Unlike TVs, projectors are actually one part of a multipart system. The screen, room, and projector all play a role in the final image you see. A projector can be perfectly accurate (more on this below), but the image can still look wrong because of how the screen is affecting it. The main factors we considered when testing a projection screen were: gain, color accuracy, viewing angle, and texture.

Gain is a measurement of how much light the screen reflects. A gain of 1.0 means it reflects the same amount of light as an industry standard white magnesium-oxide board. Screens can reflect less light and have a gain of less than 1.0, or more light and have a gain higher than 1.0. A lower gain will produce deeper, darker blacks but reduce overall image brightness. In the early days of digital projection, this was useful because projectors had terrible (read: grayish) blacks. But that is less of an issue now with most decent projectors.

A higher gain, made possible by special screen materials, reflects more light back toward the center of the room. This creates a brighter image, but it also reduces viewing angles and can introduce hot spots (areas of the image that are noticeably brighter than other areas). It used to be that a higher gain was necessary, but as projectors have gotten more powerful, today a gain of 1.0 is often sufficient.

Color accuracy measures how well the screen reflects the colors projected onto it. The makeup of the screen can result in certain colors being absorbed more than others and introduce a tint to the image that isn’t coming from the projector. Many projectors ship with picture modes that are close to accurate out of the box, but those might no longer be accurate after they hit the screen. A screen that introduces as little color shifting as possible is ideal. The two images below show the same image on two different screen materials. You can easily see the color shifts between the two and the problems a screen can introduce.

Viewing angles influence how wide you can sit from the center of the screen before the light noticeably drops off. With a gain of 1.0, the viewing angle can be close to 180 degrees, since it reflects everything more or less equally in all directions. With a higher gain, the viewing angle gets smaller, as you are in essence “focusing” the reflected light more toward the center of the room. With a high-gain screen, you’ll want to put seats closer to the center of the screen.

The texture of the screen also impacts how much detail you can see. If a screen’s texture is evident from a usual seating distance, it will alter the image quality and possibly your enjoyment. If the screen material is very fine, then you will not see any texture from a normal viewing distance, so the image appears smooth.

Almost all of the screen reviews out there are of expensive screens, so we had to start from scratch. I first went to the AccuCal Projection Screen Material Report. W. Jeff Maier of AccuCal has tested samples of many screen materials using high-end equipment to determine their color accuracy and actual gain. Since he is dealing with only samples of the materials (often 8½- by 11-inch pieces) that he is sent through the mail, the report doesn’t go into construction or installation of the screens themselves.

Next, my research turned to the main AVSForum and other resources. Here the screen conversations range from the top-of-the-line Stewart to a DIY option for $3 from Home Depot. There are also many small Internet Direct companies that would otherwise go unnoticed without discussions at AVS and other locations.

We also pored over reviews from Amazon, making sure to carefully read what people actually complained about. I also talked to other reviewers and calibrators to find out what they might have used and seen in their work that impressed them, even if they had not formally reviewed that particular screen.

After all that, we set out to review 100-inch, 16:9 screens, as close to 1.0 gain as possible. We figured this was a good-size, average screen that would work for most people. You can certainly go larger, though the image will be dimmer (by an amount equal to the increase in screen area). Since most modern home theater projectors won’t have an issue creating a bright image on a 100-inch screen (and most can even do larger), we didn’t feel anything higher than a 1.0 gain was necessary. Since most content is 16:9, that was also our preferred screen shape, though many companies make 2.35:1-shaped screens as well.

We didn’t test pull-down screens or ambient-light-rejecting materials unless we already had a sample around. Those are more specialized cases, and we were looking for the screen that would be best for the greatest number of people in a semi-permanent home setting.

We were looking for a roughly 100-inch, 1.0-gain, 16:9 screen that had very little color shift, no noticeable texture, good viewing angles, and easy installation and setup. And, ideally, was very inexpensive.

So to sum up, we were looking for a roughly 100-inch, 1.0-gain, 16:9 screen that had very little color shift, no noticeable texture, good viewing angles, and easy installation and setup—and, ideally, was very inexpensive. With that in mind, we ended up bringing in the Silver Ticket STR Series 100″, the Elite Screens SableFrame 2 100″ in CineWhite, the 100-inch Stewart StudioTek 130 and Cima Neve 1.1 screens, three 120-inch screen materials (blackout cloth, FlexiWhite, and FlexiGray) from Carl’s Place, Wilsonart Designer White laminate in an 8- by 4-foot sheet, Goo Systems" Screen Goo Reference White and GooToob, and Home Depot"s Behr Silver Screen. I also included in the testing my personal screen, a 122-inch Screen Innovations SolarHD 4K.

The Stewart and Screen Innovations screens are much more expensive models that are often sold only through custom AV retailers, but we still included them in our tests as references for comparison. Stewart is the best-selling screen brand for custom home theaters, and the StudioTek 130 is the company"s best-selling material. It is the reference standard for a home theater screen and the one most reviewers are likely to recommend if you ask for a single suggestion; I use it when testing projectors. In our tests of screens, we wanted to make sure to pit everything against this reference to see how well they performed.

For decades, we’ve lived with an inconvenient technological truth: Cameras and other sensors cannot occupy the same space as our screens. It’s why, increasingly, smartphones rely on the dreaded “notch” as a way of maximizing screen-to-body ratios while preserving the front-facing camera and other sensors.

But it turns out that cameras and screens aren’t quite as incompatible as they seem. Thanks to improvements in manufacturing techniques, these two adversaries are about to end their long-standing territorial dispute. This isn’t a far-flung prediction; it’s happening right now.

Complaining about a phone notch, hole-punch or a large screen bezel is the very definition of a first-world problem. And judging from Apple’s stellar sales numbers, none of these side effects of forward-facing cameras are dealbreakers for buyers.

First, it lets you make phones that have true edge-to-edge screens. Videos and photos look better, and app developers can make use of every square millimeter for their designs — all while keeping the phone’s body as small as possible.

Screen technology is dominated by two kinds of displays. The most common are liquid crystal displays (LCD), which include LED TVs and QLED TVs. The second, organic light-emitting diode (OLED), dominates smartphones and tablets, and is growing in use in laptops and even desktop monitors

LCDs are actually transparent when not in use — that’s why you see a gray background on a calculator screen wherever the black digit segments aren’t active. But taking advantage of this transparency to take a photo poses big technical hurdles, especially once you factor in the need for a backlight.

One solution favored by Xiaomi and Oppo in their UDC prototypes is to rely on an OLED pixel’s inherent transparency. When an OLED pixel isn’t being used to emit light, it lets light in. So you can place a camera behind an OLED display and it will be able to gather enough light to capture images. But there’s a catch: You still need to place the camera at the top or bottom of the screen, because when the camera is active, the OLED pixels above it must be shut off, which creates a temporary black area on the screen. That approach is a solution to the notch and hole-punch problem, but it does nothing to solve the downward gaze issue.

The first commercially available phone with an under-display camera — the ZTE Axon 20 5G — uses this technique, but it also suffers from a less-than-ideal compromise. Modern smartphones have incredibly densely packed pixels. The iPhone 12 Pro has a 460ppi (pixels per inch) display, which means that there are more than 200,000 pixels in one square inch. Sony’s Xperia XZ Premium had a whopping 807ppi screen (more than 650,000 pixels per square inch).

Punching holes in between those pixels, even with a laser, is so tricky that ZTE had to remove some pixels from the area above the camera to buy some extra room. The result is a noticeably lower-resolution square on the screen.

A lower-resolution section of the screen might not bother you when it’s near the top, in an area that’s used mostly for inconsequential information. But few people would accept such an obvious reduction of resolution in the center of their phone’s display, which is what we would need to counteract the downward-gaze problem.

Helander claims the self-assembly process works on any screen size, and lets manufacturers decide how many openings are needed — from just one to 1 billion.

We’ll need some kind of reliable indicator of when the camera is active and an equally reliable way of disabling it. Because it’s under the screen, there’s no way to physically block the lens without blocking content on the screen as well.

Smart speakers like the Google Nest mini ship with physical switches that can be used to disable the microphones. Assuming that there’s no way to remotely overcome the switch’s position, it provides a very good level of trust. A similar mechanism on TVs, monitors, and laptops should come standard once cameras become invisible.

There are many things that factor into what would be the best monitor (contrast ratio, response time, gamma display, etc.), and the biggest factor in these is how the screen is constructed.

Here is an explanation from jaguarskx on Tom"s Hardware (in 2007, I might add), and yes, I consider "jaguarskx" to be the preeminent expert on LCD panel types:

TN = Twisted Nematic - These are 6-bit screens that cannot really reproduce 16.7 million colors. They can only reproduce 262,144 colors; 64 shades of Red, Green & Blue. Thats (2^6)^3 or 64^3. All the other colors are created through a process called dithering. These typically have fast response times (for gaming) at the expense of color accuracy. These are inexpensive monitors.

MVA and PVA panel are the most common 8-bit LCD screen around. They are relatively slow compared to TN, but offers better color accuracy. Good viewing angles and contrast ratio. However not all MVA and PVA panels are 8-bit screens. S-MVA and S-PVA are typically the ones that are 8-bit panel from my research. S = Super.

8-bit LCDs can truly reproduce 16.7 million colors. That"s because there will be 256 shades of each color (2^8 ); Red, Green & Blue. Therefore 256^3 = 16.7 million (actually, a little more).

S-IPS = Super In-Plane Switching. These are high end and really expensive LCD panels. All these panels are 8-bit panels and comes the closest to CRT image quality. From what I"ve read they also have very good response times as well. LCD monitors geared towards graphic artists who demands the most color accuracy are designed with these type of panels. That means the shades of color you see on the screen are the exact shades that will be printed out on a good color printer.

Despite sunny advertisements of smiling people using their laptops outdoors, most laptops rely on LCD screens, and those screens do not respond favorably to natural daylight. While your visibility -- or lack thereof -- depends on your laptop"s exact screen specifications, you have plenty of options for remedying the situation, ranging from simple tweaks to some no-nonsense, and potentially costly, solutions.

Master Your Environment If you can"t see your laptop"s screen in the daylight, the most reliable -- and cost-free -- solution is to find some shade. Even if it"s sunny out, shade immediately increases the visibility of your laptop"s monitor. If you"re unable to find a shady nook such as a porch, awning, umbrella, tree or building, position your body so that your back is to the sun, casting your shadow over your laptop"s screen. It"s not a perfect solution, but it does help bolster basic visibility.

Tweak Your Settings In addition to finding a shady corner, customizing your laptop"s display offers another free solution to daylight visibility woes. Go with a high-contrast color scheme that relies on stark blacks and whites rather than bright colors or subtle shades of gray to significantly increase outdoor readability. On Windows operating systems, you can find a few pre-made high-contrast themes under the Personalization Control Panel. Likewise, set your LCD"s brightness to its maximum setting and increase your laptop"s default text size for less strenuous outdoor viewing.

Deck Out Your Screen Consider investing in a laptop accessory, if outdoor visibility is a consistent problem. A variety of manufacturers offer structured cloth and plastic laptop “hoods” or shades, which fit over the laptop monitor to shield its front and sides from sunlight. Typically, these devices leave the keyboard free of obstruction and collapse into a more portable form when not in use. This solution caters to those who use their laptops in daylight often, as laptop shades generally cost between $25 and $40, as of 2013 prices.

Beef Up Your Hardware If your work requires you to take your laptop outside constantly, a device with a specialized indoor-outdoor display may be worth a look. These screens -- often included with more ruggedly designed laptops -- which are typically significantly more expensive than standard laptops -- help increase outdoor visibility via reduced-glare construction, enhanced monitor brightness and a boosted contrast ratio. Look for labels such as “outdoor view,” “enhanced outdoor monitor” or “transflective.”

If you want sharp image quality, 4Kresolution is where you want to be in 2023. Sure, there are 8K screens and even more modest 6K ones(opens in new tab) making the rounds these days, but they cost a pretty penny. And lower resolutions deliver higher frame rates on even the best graphics cards. However, 3840 x 2160 sits at the upper echelon of premium viewing experiences for what our eyes can perceive. So for most people, whether you"re gaming, watching a movie, surfing the web, watching your coworkers call you on the best webcams or getting work done, 4K is an ideal fit. And with one of the best budget 4K monitors, you can get there without breaking the bank.

4K was a luxury that wasn"t achievable for a reasonably priced PC monitor for years. But as these high-resolution screens have become more commonplace and the bleeding edge has turned to high refresh rates and full-array local dimming, a relatively large assortment of budget 4K monitors will allow you to take the plunge without shelling out several hundred dollars.

What size do you need?For a budget monitor, 32 inches is a nice sweet spot, providing ample screen space while still fitting atop a desk. If you don"t need to share the screen, consider 28-inch and 27-inch screens. They"re common in this price range and generally less expensive.Decide the monitor’s main purpose. For gaming, higher refresh rates and Adaptive-Sync (AMD FreeSyncor Nvidia G-Sync) are priorities, alongside a beefy graphics card. You should have a minimum of a GTX 1070 Ti or RX Vega 64 for medium settings at 4K or, for high or better settings, an RTX-series or Radeon VII. For general productivity or entertainment, look for high contrast for high image quality. Creatives should strive for accuracy. For more, see How to Buy a PC Monitor, plus our Best Gaming Monitorslist.Errors under 3Delta E(dE) are generally invisible to the naked eye. A monitor with a 5dE color error, for example, probably has colors that look visibly off. Accuracy is a bigger priority for creative work.Do you need HDR? A 4K monitor with the right HDRimplementation makes 4K/HDR content look much better than it would on a regular, SDR monitor. While many 4K monitors support HDR, few budget ones deliver it with noticeable impact. If you want a monitor that makes the HDR upgrade worth it, consider increasing your budget or opting for a lower resolution to save money. Read How to Choose the Best HDR Monitor for more.Consider ports and other features.Do you need HDMI 2.1 and/or the latest DisplayPort (1.4)? How important are USB Type-A ports to you? Do you want USB-C for charging or a single-cable setup? Speakers and the stand’s ability to tilt, swivel or rise are also considerations.

Ultrawide screens typically offer more noticeable curves, but despite its 16:9 aspect ratio, the UR59C"s1500R curve is pronounced and beneficial, allowing us to keep more windows in view.

You’ll have to pay a hefty price for a monitor that can push 8.3 million pixels at a 144 Hz refresh rate. The best budget 4K gaming monitor, the Asus TUF Gaming VG289Q, is a slower 60 Hz but fights screen tears with FreeSync. Yes, input lag is significantly larger than what you’ll find on a 144 Hz monitor, as is response time. But this is an excellent option if you’re working with a budget graphics card and want your games to look detailed and realistic. SDR games looked extra colorful on the VG289Q, and dynamic contrast brought subtle visual benefits, like added dimension. However, there are screens on this page with better contrast.

The Dell S2721QS earns the title of best 27-inch budget 4K monitor with a bright screen, reliably accurate image, and useful add-ons. Those bonus add-ons include the ability to connect multiple PCs and view them simultaneously via picture-in-picture or picture-by-picture and an optional app that makes it easy to calibrate the screen or arrange up to 6 windows in various preset layouts. The latter is a productivity boon.

HDR isn’t this monitor’s strong suit. We recorded undersaturated color in this mode, as well as visible grayscaleerrors. And this monitor doesn’t have the speed or Adaptive-Sync (FreeSync or G-Sync) to make it an appropriate gaming screen.

But in terms of image quality, this is a bright screen, hitting 393 nits in our testing, along with solid contrast for an IPS monitor (1,101:1). You can also expect accurate colors. We recorded just a 2.6dE error with sRGB color.

The HP U28 is one such screen and the best budget 4K monitor for creatives. Of course, none of the monitors on this page are color slouches, but the U28 stands out with its ability to accurately cover both the sRGB and P3 color spaces with just a switch in the OSD and no calibration. You also get an adjustable stand that allows height and swivel adjustments and the ability to flip into portrait mode, offering plenty of flexibility for creative work.

The Samsung 27” S80UA is a little more expensive than the other monitors on this page, but you won’t have to worry about image quality. It’s super colorful for a budget screen, covering 95% of DCI-P3, according to our testing, and accurately. You can also opt for sRGB mode, which also offers a low color gamut error of just 2.8dE.

You also have DisplayPort and HDMI options, and even a headphone jack. But there are no speakers, and like many budget 4K screens, HDR is a bust. You’re better off watching your HDR movies in the monitor’s SDR modes, but color will still look great. On top of that, the stand is reliable, even in portrait mode, but is a little low, despite height adjustment.

While buying a new smartphone, we make sure to accessorise our phone well. We doll it up and take care of it like a baby. But one of the most important things is its screen protectors. Choosing between screen protector vs tempered glass is essential while ensuring your phone screens’ well-being. They will help you shield your phone screens from everyday scratches, breakage or any other damage.

All it does is add an extra layer of protection over your regular phone screen. Especially if you are accident-prone or clumsy, you need to cover up your phone screens right away using the screen guards. Investing in a good screen protector vs tempered glass is probably the best way to reduce the chances of getting damaged screens, thus letting your phone have a longer lifetime. However, replacement or repairing a damaged screen could cost you a fortune. One can not afford to risk it. Better safe than sorry, no?

Choosing the right screen protector vs tempered glass for your smartphones could be a tricky one. Having a debauched quality is deadly. It is similar to wearing gloves to escape the dirt and expecting them to protect your wrist bones against fracture. There are many varieties to choose from. We will assist you appropriately so that you make an informed decision. You might be confused about whether to go for a tempered glass protector or the plastic one. Let’s go through various aspects you need to pay attention to by cautiously weighing their cons and pros so that you make an exemplary and smart purchase.

Cracked or broken touchscreens are very commonly seen rather than intact ones. Plastic screen protectors vs tempered glass are universally found in the market. Just like a coin, they have both pros and cons. Let’s analyse them:

Plastic screen guards are very resilient in making them last longer. Experiments have shown that hammering or even dropping it from a height onto rocks has no effect on the plastic screen protector vs tempered glass.

Another pro linked with the plastic screen protectors is this that they are reusable. At any point, you can take them off, store it and use it again later. This feature ensures their long-term usage. In case you need to put on a waterproof case, you can take the plastic ones off and put the other one on.

There are many downsides which come along the plastic screen guards. Due to being made up of plastic material, over time these protectors lose their clarity. That often results in haziness and looks repulsive while one uses them.

It is relatively thinner than the glass tempered screen protectors. The thicker the screen guard, the tough it is and thus affording our screens resistance against damages.

These are not fingerprint resistant and leaves them on your screen after you use your smartphones. It doesn’t look so pleasant. You need to often wipe them off your screen after usage.

Tracking your fingers and navigating over a plasticscreen protector vs tempered glass may not feel as smooth as when you are using the tempered glass screen protector.

In one line, these are everything the plastic ones aren’t. They are the exact opposite of what we mentioned above. They are the more traditional choice for those who wish to cover their phone screens without harming the edges. Tempered glass screen protectors are made by extensively heating the glass and quickly cooling it. As the glass endures both extreme heat and then rapid cooling, they end up being incredibly stronger.

Tempered glass screen protectors contain multiple layers, including an oleophobic nano-coating, anti-shatter film and a penetrable silicone coating on top of the tempered glass. These compressed layers add to the heat and scratch resistivity of the tempered glass as much as five times stronger than normal glass.

They may be a costlier alternative than the plastic ones, but it safeguards your device better. Tempered glass screen guards are much sturdier and robust in nature than the former.

You might not even notice they are on the top of your mobile screen. It doesn’t make your phone look hideous by not compromising with the look of your smartphone. They provide you clarity as much as your smartphone would without any screen protector over its screen.

In case if your tempered glass breaks, it breaks into small, blunt chunks and that doesn’t compromise with the safety it was providing to your phone screen.

Since it is a glass, chances are you might cut yourself after a bad chip. You shouldn’t reuse a cracked tempered glass screen protector, unlike the plastic ones.

Tempered glass screen guards don’t offer as much impact protection as promised by a plastic screen guard. The hammer experiments we mentioned above are not meant to be run on these tempered glass screens.

A plastic screen protector is comparatively a lot cheaper than the tempered one. You can buy multiple plastic protectors at the price of a single tempered screen protector. This is chiefly due to the quality of the plastic or glass.

The plastic screen guards are not as sleek and modish as the tempered glass screen protectors. Instead, the tempered glass gives you a pleasant look at your smartphone.

Installing the plastic screen guards on your phone screens is quite more tedious than the tempered glass ones. There are various kinds of glass protectors for tempered glass screen protectors, such as full or bezel adhesive.

You can feel the difference between both plastic and tempered glass screen protectors. Your fingers glide smoothly over the tempered glass, and it’s amusing to use. They feel more like the original screen.

Screen protectors can safeguard your smartphone up to a limit. However, no matter which one you opt for, you need to be careful with your smartphones. While this is entirely your choice which screen protector to go for, in our opinion, a tempered glass screen protector is a much more valid, resistant and solid alternative. In a nutshell, the plastic one gets dull over time, but the tempered glass one is modish.

Tempered glass screen protectors were first introduced to the market in plastic protectors. However, when it comes to the ever-changing demands of the smartphone world, a plastic screen protector can no longer adapt its qualities or features to meet those needs. There are a lot of distinctions between tempered glass and plastic screen protectors that have been covered in this post.

There may be additional elements that impact your choices for screen protector vs tempered glass, but it is evident from the information provided above that, on average, a glass screen will be the most effective option. This is because they are more convenient to use, are more pleasant to look at, and provide more protection.

Most people consider overhead and ambient lighting to be the biggest factor when it comes to light sensitivity. The light that computer and device screens emit can be just as troublesome. The way the screens are lit and how they perform when dimmed can affect how you feel.

LCD screens are backlight by a fluorescent bulb – and they have the same issues as any other sort of fluorescent light. Dimming LCD screens can helpful, since the less intense the light from a fluorescent is, the less intense the invisible flicker is. Screens that are too dark can cause eyestrain, so be sure you find a comfortable balance.

LED-lit LCDs are, unsurprisingly, lit by LEDs. LEDs can only be completely on or completely off. To simulate any brightness less than 100%, they must pulse on and off. Dimming these screens causes an invisible flicker that is otherwise not an issue with most LED screens. Just like with fluorescent lights, the flicker is undetectable to the human eye, but the brain can still pick it up and make you feel ill.

If you have an LED-lit LCD that bothers you try keeping the brightness at 100%. If that"s uncomfortably bright, try adjusting your computer’s white balance to make the light warmer or use a program like f.lux, which automatically changes the white balance according to the time of day.
