Killexams : HP Pavilion Plus 14 review: Decent work laptop with a high price tag HP Pavilion Plus 14 review: Decent work laptop with a high price tag © Provided by India Today HP Pavilion Plus 14 review: Decent work laptop with a high price tag

Buying a premium productivity-focused laptop, especially in India, can get tricky. On one hand, there are loads of value for money and good-looking notebooks from Xiaomi and Realme in the Rs 50,000 bracket. If your budget is higher, Apple's premium and capable M1-series laptops are available for over Rs 90,000, but on a good day, you can buy a MacBook for roughly Rs 80,000 during an online sale event. Then, there are laptops such as HP's new Pavilion Plus 14, which looks good in terms of design and specifications, but the Rs 81,999 pricing may make some customers hesitant.

This is why I was eager to test the new Pavilion Plus 14, which makes no compromises build-wise. The laptop fully features a metal body that feels premium and increases its durability. It is also the rarest Windows-running notebook that allows users to flip open the lid with one hand. However, internally, the specifications are modest for this price. It comes with a 12th-Gen Intel Core i5 CPU paired with Iris Xe graphics. Thankfully, memory-wise, this high price tag brings 16GB of DDR4 RAM and 512GB of SSD storage.

But a pertinent question remains: Is the HP Pavilion Plus 14 worth Rs 80,000, and should you consider buying it? Here's a long-term review.

HP Pavilion Plus 14 design and display

Starting with the design, I can confidently say that HP has made no compromises in the build quality, and its premium metal finish justifies the premium price tag - to an extent. The laptop is sleek and highly portable. There's a metal finish almost everywhere and I thoroughly liked its Natural silver aluminium colour, which is much better than the traditional black shade.

In my six-week review, I carried the Pavilion Plus 14's to numerous places, and the weight didn't bother me. In fact, I carried the laptop during a latest international trip,  and believe me, every gram in your luggage at that point counts. Even then, the Pavilion Plus 14 easily fit in my backpack without taking up too much space and adding substantially to the overall weight.

HP has also added support for charging via a USB-C port. It essentially means you can skip the proprietary charger in the bag, which often increases the weight. I hardly carried the bundled 90W charger to work as well. Instead, I kept my Android phone's Type-C cable and adapter, which were more than sufficient. 

Physical connectivity options include two USB-A ports, two USB-C ports, a 3.5 audio jack, and an HDMI port. There's also a slot for an SD card reader, which I quite like and helped me substantially to transfer files from the GoPro Hero 11 to the laptop during my trip. On a side note, you can also check my review of Hero 11 if you're an upcoming creator/ influencer.

As the name suggests, HP Pavilion Plus 14 sports a 14-inch screen. The IPS display offers a 2.2K (2240 x 1400 pixels) resolution with 300 nits of brightness, 100 per cent sRGB colours, and anti-glare tech support. On paper, the display specifications look modest, and most users will be satisfied with the quality. If your priority is a laptop for movie consumption, the HP Pavilion 14 Plus is not the best companion. In that case, Asus has a bunch of notebooks under Rs 60,000 with OLED displays that offer a much richer viewing experience. On the flip side, those laptops feature a sub-standard build quality.

That being said, the display on the Pavilion 14 Plus isn't poor, and it offers decent brightness and response. I compared its display against the mini-LED screen on the iPad Pro 12 (2022). The differences are stark, but a brighter screen could've provided HP with some edge.

However, the dual speakers tuned by bang and Olufsen on the Pavilion are dreadful. In my test, the speakers failed to offer loudness and adequate bass. In other words, the Pavilion 14 Plus display for work is sufficient. For watching movies without headphones - poor.

HP Pavilion Plus 14 performance

When you're spending Rs 80,000 on a laptop, customers won't want any compromises with the processor and storage. On that front, the HP Pavilion Plus 14 checks crucial boxes. But there's a big problem too, and more on that later.

The laptop comes with a 12-core Intel Core i5 (5-12500H) processor, clocking at up to 4.5GHz with Intel Turbo Boost tech to offer extra juice during demanding tasks. As mentioned, the processor comes paired with 16GB of DDR4 RAM and 512GB of SSD storage. There's no LAN port on the laptop, but there's support for Wi-Fi 6E, which I couldn't test, though I do like the addition.

Now, there are two sides to the performance. In terms of benchmark, the Pavilion 14 Plus' scores are average, given the high price tag. On PC Mark 10's CPU test, it scored 4,269, which is mildly better than the Intel Core i3 (1220P)-powered Asus Vivobook 15 (X1502) scored in my review. Mind you, the latter costs Rs 44,990, which is much more affordable than the current HP notebook. Similarly, the GPU score on the 3D mark came to be 758 - again, average at best.

However, the 16GB RAM gives the HP Pavilion 14 Plus an edge over rivals within and below the price range. For everyday work, the laptop runs without any stutters or heating issues. 

Switching between multiple Chrome tabs and folders also did not cause any trouble either. I even like the keyboard and trackpad on the HP Pavilion Plus 14, as the duo offers good feedback and finish. The trackpad includes a fingerprint reader, which functions smoothly. In fact, I like the fingerprint scanner much better than the ones on some affordable Asus and Dell laptops, thanks to its responsiveness. 

Since the laptop is focused on productivity, gaming is doable but not ideal. On one hand, it has sufficient juice to run Age of Empires 5. However, if you want to play action titles like Apex Legends, look for a laptop with a better GPU and display with a high refresh rate. Running spreadsheet apps also wasn't a problem. I do feel that one should get a laptop with a 15 or 16-inch display if they want the best Excel or Google Sheet experience.

HP Pavilion Plus 14 battery

Performance-wise, the HP Pavillion 14 Plus managed to work fine, but all that gets shadowed by poor battery life. With regular usage (80 per cent brightness, 50 per cent audio levels), the laptop offers just 4.5 hours of battery life. If the brightness is increased to the maximum, the battery life gets poorer. And if we lower the setting, the Pavilion 14 Plus offers up to 5 hours of backup, which is again not acceptable.

With the bundled 90W USB-C charger, it takes roughly 1-1.30 hours to charge the 51Wh battery. Therefore, forget super-fast charging.

HP Pavilion Plus 14 verdict

I began this review by saying that buying a premium laptop in India can be very tricky, and the HP Pavilion 14 Plus is one of those tricky notebooks to recommend. In terms of build, I do not have any complaints, and it could even be a good alternative for MacBooks - purely based on design.

It can also handle daily tasks like web browsing, watching movies, video calling, and light gaming without much stutter, but the poor battery life makes the experience loathsome. And beyond all this, the Rs 80,000 is simply perplexing and personally, dissuades me from buying it. However, if the price drops to Rs 55,000 -- it could be a good buy, and HP could consider pricing it aggressively.

Just to be clear, the mediocrity of this laptop does not mean that HP falls short of ideas. The company still owns a large market share in India, and the new laptops in its Envy and Omen portfolio are very capable. But the Pavilion is what attracts the masses, and HP should consider making it feature-packed yet affordable.

Killexams : Nissan Ariya EV Passes Moose Test With Flying Colors

The all-electric Nissan Ariya is a very important vehicle for the car manufacturer and while we’ve not yet had the opportunity to drive it, it appears to have quite a lot going for it.

Not only does the Ariya have a very attractive exterior design, but its interior is very modern and seems like a significant upgrade over all other current Nissan models. But, how does it perform in the dreaded moose test?

To find out, km77 jumped behind the wheel of the Ariya and set about answering that question. The example it tested was equipped with the available 20-inch wheels with 255/45 Michelin Primacy tires and had the small 64 kWh battery pack and a single 218 hp electric motor driving the front wheels.

Read: Nissan Offers Free Charging, Maintenance, And Roadside Assistance With EV Carefree+

The first attempt saw the driver attempt to complete the moose test at 77 km/h (47.8 mph). While the electric SUV performed well, it did experience a touch of understeer and clipped a cone on the first attempt. However, in a second attempt at 77 km/h, the Nissan passed with flying colors, navigating its way through the cones without hitting any of them and remaining easy to control.

The Spanish publication then proceeded to test the Ariya through a slalom course. The electric SUV completed its run with a best time of 25.5 seconds. To put that time into perspective, it is much slower than a Polestar 2 Long Range Dual Motor Performance Pack with its time of 22.8 seconds but slightly quicker than a Toyota Aygo X Cross Play and a 1.0-liter Skoda Fabia Ambition. It was also just 0.2 seconds off matching the all-electric Peugeot e-2008.

Killexams : Did HP Really Build a Robot?

It looks and acts like an autonomous robot, but as you watch the machine in action, you realize it’s drawing construction markings. This is HP, so of course, it’s a printer.

At Autodesk University, HP introduced and demonstrated its HP SitePrint robot. The automated robot draws complex construction site layouts in less time than the manual process. SitePrint removes a bottleneck in the construction process. HP noted that the robot can Improve productivity by as much as ten times. “The goal of SitePrint is productivity,” Xavi Juarez, director of construction services at HP, told Design News. “We had a team that started working on this more than four years ago. The objective was productivity gains. We did the testing at customer sites. We worked on more than 80 projects.”

SitePrint was designed for autonomous operation, including obstacle avoidance. Juarez noted it can print lines and complex objects accurately with consistent repeatability. The text-printing capabilities bring data from the digital model to the construction site. “The issue this solves is the time it takes to do this work while other construction work waits,” said Juarez. “It’s hard to find skilled people to do this work.”

The concept of SitePrint came from an internal idea competition at HP’s Barcelona research and development center. “It began as an innovation contest for employees. We set up teams that had to go through a process with milestones and validation with customers,” said Juarez. “This was the winning one. After an in-depth investigation, we funded the team for further development and testing.”

According to HP, SitePrint includes a suite of technologies designed to automate the site layout process. The technology includes:

  • A rugged and autonomous robotic device designed to operate in the conditions of the construction site. Light and compact, it is very transportable, including a hard case that fits all the solution components
  • Cloud tools to submit and prepare jobs to be printed, manage the fleet, and track usage
  • A touch screen tablet for remote control and configuration
  • A portfolio of inks for different surfaces, environmental conditions, and durability requirements

HP brought customers into the development process of SitePrint to make sure the robot was able to deliver the accuracy of a skilled worker. “The existing manual layout process can be slow and labor intensive. Despite being done by specialists, there is always the risk of human error, which can result in costly reworks,” said Albert Zulps, director of emerging technology at Skanska, a construction and development company that utilizes SitePrint on two US projects. “Layout experts are a scarce resource who add a lot of value in terms of planning and strategy, but often end up dedicating most of their time to manual execution.”

HP’s SitePrint robot is available now to customers in North America through an early access program. The final product and a wider commercial launch are planned for 2023. “The manufacturing will be done in Barcelona.,” said Juarez.

Killexams : XR in Health Care: How Michigan Medicine Provides a Safe Space to Practice High-Stress Environments

Disclosure: University of Michigan is an HP customer and has received loaned and/or donated equipment from HP.

XR projects can provide cost savings, increased access, and better feedback for users, transforming in-person trainings at medical centers and institutions at large.

Case Study
Credit: Muslianshah Masrie / © 2022

Institutional Profile

One of the nation’s top public universities, the University of Michigan (U-M) has been a leader in research, learning, and teaching for more than 200 years. With the highest research volume of all public universities in the United States, U-M is advancing new solutions and knowledge in areas ranging from the COVID-19 pandemic to driverless vehicle technology, social justice, and carbon neutrality. Its main campus in Ann Arbor comprises 19 schools and colleges; there are also regional campuses in Dearborn and Flint and a nationally ranked health system, Michigan Medicine.

The Challenge/Opportunity

When a patient in a medical center experiences cardiac arrest, an interprofessional team of healthcare professionals come together to help, including doctors, nurses, respiratory therapists, and others. This group can sometimes include as many as fifteen people, and these professionals must work together to make quick decisions in a very intense environment with someone’s life on the line. A lot of skills are put to the test, and without training it can be difficult for medical teams to work together effectively to deliver the right treatment at the right time. “The problem isn’t the medicine. These healthcare professionals know the medicine. The problem is on the nontechnical side,” said Michael Cole, associate professor of emergency medicine at the University of Michigan Medical School (Michigan Medicine). The people in these situations are dealing with an incredibly high-stress and high-stakes environment that requires important cognitive and behavioral skills that are not typically emphasized in conventional healthcare curricula, skills such as situational awareness, leadership, and interprofessional communication.

In order to train personnel for the medical and nontechnical skills needed in these situations, medical centers typically send their healthcare professionals to simulation centers or purchase a medical training mannequin, which can cost upwards of $150,000. Cole was looking for options to replace this expensive and resource-intensive process, which requires learners to gather in the same location at the same time and requires a costly mannequin, a simulation center, and technical staff to run the event. After examining the potential outcomes and benefits, Cole believed that a virtual reality (VR) solution might offer a cheaper and more effective approach to training personnel for these high-stress situations. It’s much less expensive to purchase VR equipment and contract with a vendor to develop an application than to purchase the medical equipment and incur other expenses associated with running in-person simulations. Additionally, VR headsets increasingly include capabilities that can deepen the experience and expand the data collected. The Reverb G2 Omnicept Edition headset from HP, for example, provides a data stream on users’ attention, cognitive load, eye tracking, and other sensory information that can help provide more tailored feedback for trainers and trainees.

After conducting a needs assessment, the stated goal for this VR project was to “develop a multi-user, VR-based app that allows healthcare professionals to train in cardiac arrest care in a collaborative manner that provides them feedback on both their clinical decision-making skills as well as the cognitive and behavioral science—based skills necessary to optimally run a high-performance team.”


Cole approached this challenge in a planned and collaborative manner, working internally with colleagues at Michigan Medicine, as well as collaborating with Jeremy Nelson, senior director of XR, Media Design & Production at the University of Michigan, and external vendors. Initially, Cole sought the current resources available at the institution to help identify the initial steps required to bring his VR cardiac arrest training simulation to life. He made efforts to have conversations—not just email threads—with the medical IT group, the main campus IT group, procurement, and the legal department. Those conversations led Cole to begin an official RFP process to help identify the right technology necessary for the training simulation, and during that process, Nelson and other IT professionals evaluated and recommended the most promising headsets. The in-person conversations also helped ensure project stakeholders were on the same page and following the relevant institutional policies. Throughout the process, Nelson was able to help bring essential expertise to the project and act as an advocate between Cole and the various stakeholders across and outside the institution. Cole and Nelson were able to create a multidisciplinary team that brought together essential skills across areas including medicine, analytics, vendor management, procurement, and business operations.

As part of the procurement process, Michigan staff interviewed several potential vendors for the creation of the two necessary aspects of their VR setup: the real application that users would interact with in VR, and the processing of the attentional/cognitive load data based on the sensory output from the HP Omnicept headsets, which the team had chosen for this project. The sensors provide data on eye gaze and pupillary size, as well as heart rate and heart rate variability, all aspects that are much more difficult or impossible to track in a traditional training setting (see figure 1). The sensory output allows for reporting statistics not just on the cognitive load the headset already measures but also millisecond-by-millisecond statistics on where the users’ attention is during the simulated training experience and their natural responses to that experience. The app and the analytics aspects required Cole and Nelson to work with various IT stakeholders on campus to manage challenges such as data privacy, security, and headset approval. According to Cole, one of the most valuable groups of people he worked with during this project was a subgroup in IT focused on educational research: “These people were willing to understand the innovative nature of these activities and work with us instead of just saying no.” This group provides a network reserved to connect only preliminary devices for between six months and a year before they’ve gained full IT approval, which helps staff and faculty like Cole to both test and showcase their projects, reducing the wait time as they are being developed and approved.

Figure 1. User View inside the VR Application
A screen shot of the VR application showing a member of the medical staff treating a patient, with the staff member’s current heart rate superimposed.

Nelson not only helped Cole select the headsets, but he also helped test the app and the VR systems with users (see figure 2). He ensured they conducted user experience research, including users across various levels of technological literacy, from novices totally new to VR to experienced VR gamers and medical experts. This helped ensure the best end-user experience possible and proper collection and use of sensory data. With the data collected from the live VR project, the team at Michigan Medicine has been able to provide detailed feedback to medical trainees, helping them better understand their experiences and optimal practices during a cardiac arrest. Users receive individualized feedback after completing the training, including feedback on clinical decision-making and a cognitive load score. The team is also using these data to inform the future development of infrastructure for cardiac arrest codes, as well as the creation of new guidelines and policies for these situations.

While this VR project took several years to come to fruition and encountered a few barriers and obstacles, the payoff in training for the low-frequency but high-risk event of a cardiac arrest has the potential to save lives and has helped pave the way for other VR projects at U-M and Michigan Medicine.

Outcomes and Lessons Learned

Plan your VR projects to best utilize the specific benefits VR can provide. One of the reasons this project has been successful is that the planners spent time vetting cardiac arrest training as the type of project that would benefit from the specific capabilities that VR technologies provide. The alternative to a virtual training is far more resource-intensive, the purchase of VR headsets instead of a $150,000 mannequin is an easy choice, and the VR training provides more standardized and better feedback to the users. The VR training has the potential to offer better equity and access as well—users can be training together in different countries, but they all experience the same simulation and aren’t depending on the quality of the instructor to assure a beneficial learning experience. Lastly, cardiac arrest training was best for VR because it doesn’t require as many complex, tactile sensations during the training as other procedures. No one has to practice intubating the patient or putting in an IV in these situations.

Find or create an advocate role between IT and XR business cases. Having an advocate or some kind of bridge role to help work with faculty, staff, and other educators or researchers is well worth the investment. “It takes resources to develop and dedicate this type of position,” said Cole, “but those resources will pay you back tenfold if your institution is serious about supporting XR technologies.” There are many reasons this role can be useful because that person can maintain a view of the bigger picture of XR use at the institution. Researchers and faculty are often siloed in the work they do to plan an XR project, following parallel paths of vendor approval and procurement, contract negotiations, data privacy and security issues, and device use and approval. An XR advocate can help alleviate a lot of undue burdens and common challenges that researchers and faculty face in their development process, helping document application pathways, approved devices, and important staff contacts.

Shop around to find the right developer or vendor for your project. The first step to finding the right vendor or internal developer for your VR project is to conduct a needs assessment and list exactly what will be required. This will enable potential vendors to speak specifically about their ability to meet the needs of any applications or analytics necessary for the project. Cole discovered that no single vendor was able to meet both the app development and attention/cognitive-load data needs, so the team worked with two vendors, one for each aspect of the project. In fact, an initial vendor candidate for app development recommended the attention/cognitive data vendor. “If a vendor can’t provide what you need, your last question of the conversation should be, ‘Who else do you recommend I talk to about this project?,’” said Cole. One other important part of the vetting process was looking at vendors’ previous project successes and outputs instead of listening to potential timelines and promises for the current project. “It always takes longer than what they’ll tell you; almost no one can get one of these projects done in less than 90 days,” added Nelson.

HP wants you to know its all-in on enterprise virtual reality.

Among the various names vying for a place in the enterprise VR market, HP has arguably been one of the most surprising. The company, traditionally known for its printer and PC products, has become a pillar in the VR hardware landscape in only a few years. In 2017 the company unveiled the HP Z VR Backpack, essentially a VR-ready PC in a backpack form factor targeted at enabling powerful VR experiences with greater freedom of movement. HP followed that up with its first VR headset as part of the Windows Mixed Reality ecosystem.

Now, HP has debuted the HP Reverb, a Windows Mixed Reality headset focused on the enterprise market. The headset offers significant upgrades from the previous model and doubles down on the company's commitment to the commercial VR market.

According to John Ludwig, Global Lead of VR Headsets at HP, “Back in 2017 what was a surprise to us at the time, but in retrospect quite obvious, is that HP has a large commercial enterprise business and those sales people start ringing our phones asking, 'How do we get our hands on that VR backpack and VR headset?' ”

That initial flood of interest led HP to create a division dedicated fully to VR for commercial and enterprise use cases. Where other companies were going strongly after the video game and entertainment markets – largely viewed as the greatest area of opportunity for VR, HP decided it was going to create products aimed at engineers and designers.

Those verticals have ranged from product design and architecture to training and healthcare applications. “Training has been huge for two reasons,” Ludwig told Design News. “One, it saves a lot of cost. You don't have to fly a person in to train by actually working a the physical engine, for example. You can do in VR for the first 30-40 hours and then do the finishing touches in the real world. The other thing is actually the retention rate has been quite impressive for VR-based training. Retention is about five to 10 percent for lectures or reading quiz afterwards. VR is about 80 percent.”

They Want Resolution and Comfort

HP's first generation of VR products garnered feedback from customers and communities that the company has used in creating its latest products, including the Reverb. “The simple feedback from the architecture, healthcare, and product design sectors was that they needed more resolution,” Ludwig said. “They need to be able see the details so they can make VR a tool they use more often.

“In training a big issue is actually text illegibility. A lot of training is still on documents, using multiple choice questions and things like that. And so the ability to read text very well or comfortably in current generation VR hurts their ability go from documentation to VR training.”

The other big piece of feedback HP got was in relation to comfort. Even casual VR users are familiar with issues of headset weight and overall comfort, particularly in applications like product design and training that can involve a lot of head movement. The equation is pretty simple, if you make a headset more comfortable, you provide users the ability (and desire) to wear them for longer.

HP's first VR headset wasn't designed solely by the company. The base unit work was provided by Microsoft as part of its larger strategy to maintain a certain standard among the first Windows Mixed Reality headsets to roll out.

But Ludwig said HP knew if it was going to implement the feedback it had been receiving and meet expectations, the Reverb would have to be designed from the ground up.

Indeed the most notable specs for the Reverb come in the way of resolution and comfort. The headset boasts a 114-degree field-of-view with a 2160 x 2160-pixel resolution and a 90Hz refresh rate. Mathematically, that's nearly double the resolution of leading headsets such as the HTC Vive Pro, Oculus Rift, and Samsung Odyssey.

The headset itself weighs about 1.1 pounds. And while it is not a wireless headset (it uses DisplayPort 1.3 and USB 3.0), it does offer inside-out tracking, meaning it doesn't need external sensors (or “lighthouses”) to track the wearer's movement in space.

“We're utilizing the fact that you have two eyes to increase field of view and also boost clarity."

The Reverb comes packaged with wireless controllers (the standard Windows Mixed Reality controllers). However, because Bluetooth connectivity can sometimes be unreliable, HP's engineers have opted to implement a Bluetooth radio directly into the headset to avoid having to rely on the PC's Bluetooth and avoiding possible interference from other Bluetooth devices.

In our hands-on tests with the Reverb this Bluetooth implementation did cause some initial confusion with the Windows 10 setup, but after pairing the controllers directly through the OS rather than through the provided app, we found the controllers response to be very accurate and very low latency – even in gaming applications.

The high resolution is also immediately noticeable, provided you have a PC with the horsepower to handle the Reverb (HP recommends a setup with an Intel Core i7, Nvidia GTX 1080 graphics card, and 16GB of RAM at minimum). Even the Windows Mixed Reality Portal – essentially a virtual house that you can walk through to launch apps – takes on a whole new level of detail and clarity in the Reverb.

The comfort level will also be immediately noticeable to anyone who has tried other Mixed Reality headsets on the market. Thanks to some improved weight balancing and some other design decisions related to the optics, the Reverb offers a level of comfort rivaled only by the HTC Vive Pro, but at roughly half the weight.

In our own tests we logged a record amount of time using the Reverb both in enterprise demos and playing games (we ran the headset through its paces with enterprise demos provided by HP as well as by playing Robo Recall). It's a nice feeling to have to remove a VR headset simply because you're done with a task or actually want to take a break, as opposed to having neck strain or needing to stave off a headache.

The HP Reverb comes in two flavors: a consumer and professional edition. “We're commercially focused, but we also notice when the Venn diagram of consumer wants and commercial wants overlap enough,” Ludwig said. The base specs between the two versions are the same, but with slight differences. For example, the consumer variant comes with a machine washable cloth face mask, whereas the Pro version has a wipeable leather face mask for easier sanitation and use in multiuser environments. The Pro version also has a cord so that it can be connected to the HP Backpack, the latest version of which – the HP VR Backpack G2 – HP released to closely coincide with the release of the Reverb.

Coming to an Optical Conclusion

Ludwig said for HP's team of engineers the key to really delivering the resolution and visual quality that enterprise users demand is in the optics. “[With the Reverb] we're using LCD panels instead of OLED. HTC, Oculus, and Samsung, for example, all use OLED,” Ludwig explained. “The advantage there is we actually have an RGB subpixel stripe, so for each pixel we have a red, green, and blue subpixel – meaning each pixel can make any color. The result is we have two times the resolution, but we are actually more than twice as sharp.”

The other advantage the Reverb's LCDs offer is greater pixel density. “You can't really have a good panel with bad lenses, otherwise you get a bad experience,” Ludwig said. “Quite frankly the lenses aren't the best in the first generation mixed reality devices. The sweet spot is pretty small, which leads to a lot of moving your face around until the image looks clear. And it gets a little blurry near the edges, which isn't great.”

“The other advantage of our LCD panels is they are are much more pixel dense,” Ludwig added. “We use 2.89-inch panels versus the three-and-a-half-inch panels we find for OLED in the Vive, Samsung, and Oculus. So as we basically the headset ends up being a lot smaller and a lot lighter, which also leads directly to comfort.”

Adding only four degrees to the field of view over competing headsets (114-degrees versus 110) may not seem significant, but the difference is very noticeable in use. Aside from the larger view meaning less neck movement (another plus for comfort) it also lends to an overall improvement in clarity in virtual environments.

Ludwig said HP accomplished this by actually taking advantage of a bit of opticl trickery. “We found something interesting, which is that there tends to be an inverse relationship between your field of view and the clarity of the lens in a lot of cases with this kind of technology. So as you increase field of view the lens gets a little murky.

“So what we did is we moved from a symmetrical lens – where these are just circles with your eye in the very middle – to an asymmetrical lens, where your eyes are actually more inboard on the lenses,” Ludwig said. “They're not the same shape. What this lets us do is we've actually lowered the per eye field of view – so your monocular field of view has been lowered, which boosts the clarity of the lens up a bunch and increases the sweet spot of the optics by about 33 percent.”

The magic here is that the Reverb's lenses take advantage of the fact that humans have two eyes. Having a lower than average field of view in each eye results in a larger field of view with both eyes open. “We're utilizing the fact that you have two eyes to increase field of view and also boost clarity,” Ludwig said.

“We don't want to just throw hardware at companies and tell them to figure it. That would be a classic mistake.” 

Not Just Throwing Hardware

Moving forward, Ludwig said HP wants to maintain a relationship with its customers and not just become a high-end VR hardware vendor. “What we find in the enterprise space is a lot companies are saying, 'Okay let's have our technologist make something [with VR] and see if it's actually reasonable.'In general they all find yes it is. But they're having difficulty going from that to implementing it company wide because that's a much different problem.”

To address this HP is making a support system available to its customers to help bridge the gap from making VR a nice-to-have into a regular, crucial part of workflows. “We've ramped up this support system alongside our products so that say a company comes to us in future and says, 'We have CAD or architecture files, but we don't know how to make the solution to take those into VR we can work with them to find a solution...We don't want to just throw hardware at companies and tell them to figure it. That would be a classic mistake.”

Best Cheap Laptop 2022: HP Pavilion Plus 14.
Apart from the bezels, it doesn’t look budget.

HP’s Pavilion Plus 14 is an interesting animal. The Pavilion line has traditionally included the company’s budget computers, which have been a solid step down from its higher-end Envy and Spectre models. Lately, however, HP has been releasing Pavilions here and there that are solidly in the midrange zone, with their major draw being light weight rather than competitive pricing.

The new Pavilion Plus is in that camp. It’s both the thinnest Pavilion ever released and the first one to include an OLED screen. The $999.99 (currently $819.99) model that I have, with a 12th Gen Intel Core i7-12700H, 16GB of RAM, 256GB of storage, and a 2.8K 90Hz OLED display, is a step up from the $600 Pavilions I’m used to seeing on shelves. This certainly isn’t a budget laptop anymore.

While the Pavilion Plus 14 is not the hands-down best laptop one can buy for $999 (a price point where the M1 MacBook Air also hangs out), and there are some odd flaws left over from its budget roots, it offers a combination of portability, power, and conferencing features that is hard to find below $1,000.

Here are my four favorite things about the Pavilion Plus 14, as well as my two major concerns.

For more on our scoring, see how we rate.

It’s oh, so light

My favorite thing about the Pavilion Plus 14 is carrying it around. It’s only 3.09 pounds, making it super easy to haul with one arm. I put this in my backpack and felt like I was carrying nothing. A few times, I was even worried that I might have forgotten it. It’s over a full pound lighter than the higher-end Envy x360 15. Carrying it around with two other laptops (which is a thing I often have to do for my job) is no problem. I haven’t gotten to say that about too many laptops with Intel H-series chips in them this year.

The one caveat to this is that the 90W USB-C adapter is oddly large for an ultraportable. I recently reviewed an HP Victus gaming laptop, and the Plus’ charger is close to the same size.

The display is a luxury

This is the second area where the Pavilion Plus really stands out. The 14-inch OLED display is great. It’s 16:10, with a crisp 2880 x 1800 resolution (a higher resolution than the MacBook Air), and the 90Hz refresh rate delivers a noticeably smoother scroll than you’ll find on many laptops at this price point. Deep blacks and bright whites provide excellent contrast that I noticed even while I was just doing boring work in Google Docs and such. It was also quite bright (which is not always a given with OLEDs), reaching 420 nits in my testing. That beats the M1 MacBook Air’s 400 nits of rated brightness and is plenty for most laptop use cases.

The screen is really a dream.

The webcam is unique

This Pavilion Plus has one of the best cameras I’ve used on a laptop this year. The details it delivered were accurate, lighting was well-regulated (especially in my bright office space, where I often look washed out), and noise was minimal.

Moreover, the camera supports a bunch of fancy features that you can toggle in the myHP app. There’s auto-framing, which keeps you centered as you move around your camera. (This wasn’t as smooth as Apple’s Center Stage, but it did work.) There are backlight and low-light adjustments you can turn on and off. My favorite feature, though, is “BRB Mode.” This literally freezes your video feed and puts a banner that says “BRB” at the bottom to let the folks you’re calling know that you’ll be right back. I don’t know how often people will actually use this, but it’s very funny.

Two things to note are that the camera doesn’t support Windows Hello facial logins, and there’s no physical privacy shutter (though there’s a kill switch on the keyboard).

It’s a strong performer

As raw CPU performance goes, this is likely one of the most powerful thin-and-light laptops you can buy, especially among devices with OLED screens. The 12th Gen Core i7-12700H handled my Chrome-heavy workload with very little chassis heat and no fan noise. Video calls were fine, and even basic photo work in Lightroom was no problem — I didn’t get impatient while waiting for effects to work, as I sometimes do on budget-oriented competitors like the Acer Swift 3. Performance was certainly on par with that of other top thin-and-lights, such as HP’s own Envy x360 15 (my go-to recommendation in the Envy tier).

Admittedly, an H-series processor is probably overkill for this device. It’s not marketed as a workstation or content creation machine (and the lack of discrete graphics in this model wouldn’t make it a good choice for those use cases anyway). I would probably rather HP have gone for a more efficient chip that could eke out more battery life.

Speaking of which...

The battery life isn’t great

The Pavilion Plus’ battery life isn’t quite the disaster that some H-series Intel laptops have presented this year, which is a win in itself. But the lifespan I got isn’t quite good enough for a laptop that touts portability as one of its primary selling points. During my testing period, after three and a half hours of use, I was already down to just 20 percent remaining. I averaged about four hours and 38 minutes of total continuous use. I suspect that many shoppers, if they don’t mind being limited by battery life to this degree, may prefer to go for a GPU-powered workstation with better graphical chops.

The chassis is a mixed bag

Make no mistake — the Pavilion Plus 14 is quite well-built as Pavilion models go. It’s all metal, with a recycled aluminum lid. There is some flex in various parts of the chassis, but it’s far from what I would call flimsy. The keyboard deck is quite comfortable, with a nice texture, and my keystrokes don’t depress it. The vibe, across the board, is professional and premium — except for the bezels.

The bezels stick out like a sore thumb for me. It’s not necessarily because of their size (though they’re more noticeable than they are on many modern laptops). They just look and feel quite plasticky and don’t really fit in with the quality of the rest of the chassis.

Various parts also include recycled materials, as does the packaging. This is all nice, but — as I am constantly reminding people — e-waste and energy consumption also have a massive environmental impact. In that respect, recycled aluminum doesn’t, to me, make up for the power-hungriness of this device.

Agree to Continue: HP Pavilion Plus 14

To start using the HP Pavilion Plus 14, you’ll need to agree to the following:

  • Microsoft software license terms and HP end-user license agreement

You can also say yes or no to the following:

  • Privacy settings (location, Find My Device, sharing diagnostic data, inking and typing, tailored experience, advertising ID)
  • OneDrive backup
  • Microsoft 365 free trial
  • Join PC Game Pass
  • Register with HP with your name, email address, and country or region. Allow HP to use information about your system to provide customer support and show messages (including contact options, warranty information, and support messages) from HP, to Improve HP products and services, and to send personalized offers and news.

That’s two mandatory agreements and 13 optional agreements to use the HP Pavilion Plus 14.

Despite its flaws, I see the Pavilion Plus 14 as a good midrange pick. The chassis is solid and lightweight, the camera is neat, and the screen is hard to beat at this price point. Even the MacBook Air lacks the 90Hz smoothness and OLED contrast the Pavilion can offer.

That doesn’t mean it’s for everyone. The inefficiency of the processor really makes this ideal for a small group of shoppers who are looking for heavy-duty CPU power and a great screen on a really lightweight device. If you’re not among those folks and just want a well-performing ultraportable, there are better picks for you out there.
