It is usually quoted as width × height, with the units in pixels: for example, 1024 × 768 means the width is 1024 pixels and the height is 768 pixels. This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight".

One use of the term display resolution applies to fixed-pixel-array displays such as plasma display panels (PDP), liquid-crystal displays (LCD), Digital Light Processing (DLP) projectors, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pixels creating the display (e.g. 1920 × 1080). A consequence of having a fixed-grid display is that, for multi-format video inputs, all displays need a "scaling engine" (a digital video processor that includes a memory array) to match the incoming picture format to the display.

For device displays such as phones, tablets, monitors and televisions, the use of the term display resolution as defined above is a misnomer, though common. The term display resolution is usually used to mean pixel dimensions, the maximum number of pixels in each dimension (e.g. 1920 × 1080), which does not tell anything about the pixel density of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not the total number of pixels. In digital measurement, the display resolution would be given in pixels per inch (PPI). In analog measurement, if the screen is 10 inches high, then the horizontal resolution is measured across a square 10 inches wide.NTSC TVs can typically display about 340 lines of "per picture height" horizontal resolution from over-the-air sources, which is equivalent to about 440 total lines of actual picture information from left edge to right edge.

Some commentators also use display resolution to indicate a range of input formats that the display"s input electronics will accept and often include formats greater than the screen"s native grid size even though they have to be down-scaled to match the screen"s parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 × 768 pixel array). In the case of television inputs, many manufacturers will take the input and zoom it out to "overscan" the display by as much as 5% so input resolution is not necessarily display resolution.

The eye"s perception of display resolution can be affected by a number of factors – see image resolution and optical resolution. One factor is the display screen"s rectangular shape, which is expressed as the ratio of the physical picture width to the physical picture height. This is known as the aspect ratio. A screen"s physical aspect ratio and the individual pixels" aspect ratio may not necessarily be the same. An array of 1280 × 720 on a 16:9 display has square pixels, but an array of 1024 × 768 on a 16:9 display has oblong pixels.

Most television display manufacturers "overscan" the pictures on their displays (CRTs and PDPs, LCDs etc.), so that the effective on-screen picture may be reduced from 720 × 576 (480) to 680 × 550 (450), for example. The size of the invisible area somewhat depends on the display device. Some HD televisions do this as well, to a similar extent.

The European Broadcasting Union has argued against interlaced video in production and broadcasting. The main argument is that no matter how complex the deinterlacing algorithm may be, the artifacts in the interlaced signal cannot be completely eliminated because some information is lost between frames. Despite arguments against it, television standards organizations continue to support interlacing. It is still included in digital video transmission formats such as DV, DVB, and ATSC. New video compression standards like High Efficiency Video Coding are optimized for progressive scan video, but sometimes do support interlaced video.

Many personal computers introduced in the late 1970s and the 1980s were designed to use television receivers as their display devices, making the resolutions dependent on the television standards in use, including PAL and NTSC. Picture sizes were usually limited to ensure the visibility of all the pixels in the major television standards and the broad range of television sets with varying amounts of over scan. The actual drawable picture area was, therefore, somewhat smaller than the whole screen, and was usually surrounded by a static-colored border (see image to right). Also, the interlace scanning was usually omitted in order to provide more stability to the picture, effectively halving the vertical resolution in progress. 160 × 200, 320 × 200 and 640 × 200 on NTSC were relatively common resolutions in the era (224, 240 or 256 scanlines were also common). In the IBM PC world, these resolutions came to be used by 16-color EGA video cards.

One of the drawbacks of using a classic television is that the computer display resolution is higher than the television could decode. Chroma resolution for NTSC/PAL televisions are bandwidth-limited to a maximum 1.5MHz, or approximately 160 pixels wide, which led to blurring of the color for 320- or 640-wide signals, and made text difficult to read (see example image below). Many users upgraded to higher-quality televisions with S-Video or RGBI inputs that helped eliminate chroma blur and produce more legible displays. The earliest, lowest cost solution to the chroma problem was offered in the Atari 2600 Video Computer System and the Apple II+, both of which offered the option to disable the color and view a legacy black-and-white signal. On the Commodore 64, the GEOS mirrored the Mac OS method of using black-and-white to improve readability.

The 640 × 400i resolution (720 × 480i with borders disabled) was first introduced by home computers such as the Commodore Amiga and, later, Atari Falcon. These computers used interlace to boost the maximum vertical resolution. These modes were only suited to graphics or gaming, as the flickering interlace made reading text in word processor, database, or spreadsheet software difficult. (Modern game consoles solve this problem by pre-filtering the 480i video to a lower resolution. For example, Final Fantasy XII suffers from flicker when the filter is turned off, but stabilizes once filtering is restored. The computers of the 1980s lacked sufficient power to run similar filtering software.)

The advantage of a 720 × 480i overscanned computer was an easy interface with interlaced TV production, leading to the development of Newtek"s Video Toaster. This device allowed Amigas to be used for CGI creation in various news departments (example: weather overlays), drama programs such as NBC"s

In 2002, 1024 × 768 eXtended Graphics Array was the most common display resolution. Many web sites and multimedia products were re-designed from the previous 800 × 600 format to the layouts optimized for 1024 × 768.

The availability of inexpensive LCD monitors made the 5∶4 aspect ratio resolution of 1280 × 1024 more popular for desktop usage during the first decade of the 21st century. Many computer users including CAD users, graphic artists and video game players ran their computers at 1600 × 1200 resolution (UXGA) or higher such as 2048 × 1536 QXGA if they had the necessary equipment. Other available resolutions included oversize aspects like 1400 × 1050 SXGA+ and wide aspects like 1280 × 800 WXGA, 1440 × 900 WXGA+, 1680 × 1050 WSXGA+, and 1920 × 1200 WUXGA; monitors built to the 720p and 1080p standard were also not unusual among home media and video game players, due to the perfect screen compatibility with movie and video game releases. A new more-than-HD resolution of 2560 × 1600 WQXGA was released in 30-inch LCD monitors in 2007.

In 2010, 27-inch LCD monitors with the 2560 × 1440 resolution were released by multiple manufacturers, and in 2012, Apple introduced a 2880 × 1800 display on the MacBook Pro. Panels for professional environments, such as medical use and air traffic control, support resolutions up to 4096 × 21602048 × 2048 pixels).

In recent years the 16:9 aspect ratio has become more common in notebook displays. 1366 × 768 (HD) has become popular for most low-cost notebooks, while 1920 × 1080 (FHD) and higher resolutions are available for more premium notebooks.

When a computer display resolution is set higher than the physical screen resolution (native resolution), some video drivers make the virtual screen scrollable over the physical screen thus realizing a two dimensional virtual desktop with its viewport. Most LCD manufacturers do make note of the panel"s native resolution as working in a non-native resolution on LCDs will result in a poorer image, due to dropping of pixels to make the image fit (when using DVI) or insufficient sampling of the analog signal (when using VGA connector). Few CRT manufacturers will quote the true native resolution, because CRTs are analog in nature and can vary their display from as low as 320 × 200 (emulation of older computers or game consoles) to as high as the internal board will allow, or the image becomes too detailed for the vacuum tube to recreate (i.e., analog blur). Thus, CRTs provide a variability in resolution that fixed resolution LCDs cannot provide.

As far as digital cinematography is concerned, video resolution standards depend first on the frames" aspect ratio in the film stock (which is usually scanned for digital intermediate post-production) and then on the actual points" count. Although there is not a unique set of standardized sizes, it is commonplace within the motion picture industry to refer to "nK" image "quality", where n is a (small, usually even) integer number which translates into a set of actual resolutions, depending on the film format. As a reference consider that, for a 4:3 (around 1.33:1) aspect ratio which a film frame (no matter what is its format) is expected to horizontally fit in, n is the multiplier of 1024 such that the horizontal resolution is exactly 1024•n points.2048 × 1536 pixels, whereas 4K reference resolution is 4096 × 3072 pixels. Nevertheless, 2K may also refer to resolutions like 2048 × 1556 (full-aperture), 2048 × 1152 (HDTV, 16:9 aspect ratio) or 2048 × 872 pixels (Cinemascope, 2.35:1 aspect ratio). It is also worth noting that while a frame resolution may be, for example, 3:2 (720 × 480 NTSC), that is not what you will see on-screen (i.e. 4:3 or 16:9 depending on the intended aspect ratio of the original material).

The best TVs with ATSC 3.0 not only offer excellent picture performance, but they"re fully ready to support NextGen TV when it comes to a city near you.

What is ATSC 3.0? ATSC 3.0, also known as NextGen TV, is a suite of standards that will support the world’s first IP-based TV system, which marries broadband and broadcast to deliver cord-free television. Once it goes live fully, it will offer 4K over-the-air broadcasts, better sound quality, multi-language closed captioning and a number of other outstanding features.

The technology is still in its infancy with broadcasters slowly ramping up to the full suite of features, but buying an ATSC 3.0-compatible TV means that you"ll be ready to jump on-board the ATSC 3.0 train when it comes to your area.

Unfortunately, not every TV maker is putting ATSC 3.0 hardware into new TVs. In fact, among the best TV brands, the only ones offering TVs with the new ATC 3.0 tuners are LG, Samsung and Sony, though Hisense announced at CES 2022 that it would be including ATSC 3.0 hardware in some of this year"s models.

Our favorite is the Samsung QN90A Neo QLED TV, but it"s hardly the only Samsung model. Samsung"s entire 8K lineup also includes ATSC 3.0 tuners built-in — not that we"d necessarily recommend you buy that just yet.

Sony is bringing ATSC 3.0 to every TV range announced so far in 2022, following on from considerable support last year. That means you can expect it in all of its TVs including Bravia LCD (X80K, X85K, X90K and X95K), the Master Series OLEDs (A80K and A90K) and the Master Series Z9K 8K. You"ll find last year"s Sony A80J in our list here - a superb 2021 OLED that is still well worth a look.

LG gets an incredible two mentions on the list, one for the LG G1 OLED TV, and one for the newest iteration, the LG G2 OLED. LG"s Z1 8K OLED model also has it on board. You can expect 2022"s G2 and Z2 to feature the tech too.

Our favorite TV with ATSC 3.0 hardware is the Samsung QN90A Neo QLED TV. Using a combination of Samsung"s highly refined quantum dot technology with the tight control of mini-LED backlighting, the QN90A is one of the best TVs we"ve ever seen. In our testing, we found its brilliant color handling and unmatched brightness make for a superb performance, and Samsung pairs that with a bounty of smart TV functions and genuinely intelligent features. We particularly love the solar-powered remote control that eliminates the need to swap out batteries – delivering eco-friendly design and unbeaten convenience at the same time.

The 2022 version of LG"s premium G-series OLED TVs is here — and it"s brilliant. The LG G2 OLED improves upon last year"s G1 in almost every regard to up the game when it comes to the screen tech. Brightness has been a long-time OLED shortcoming, but in our testing we found that the LG G2 reached 590.54 nits — way above the G1"s 412.05, albeit not quite on a par with the Sony A80J"s 713.65 result. And brightness is just one aspect of its performance that impressed us, with color accuracy, color gamut and lag times all faring well in our testing. And of course you get the deep blacks we"ve come to expect from OLED.

A NextGen TV tuner is just one of the cutting edge technologies built into the Sony Bravia XR A80J. This 4K OLED TV has HDR, a 120 Hz refresh rate, Google TV software and Sony"s own Bravia Core streaming service, Acoustic Surface Audio+ technology… the list goes on. Sure, not everyone will need everything here, but it"s nice to have the option.

The Hisense U8H Mini-LED TV is all about bringing high-end features to a mid-level price bracket. To wit, it’s packing a light sensor for Dolby Vision IQ that can raise or lower the brightness to match the ambient light in the room and a Mini-LED panel that has up to 528 local dimming zones. Its peak brightness exceeds any TV around that price, and its color reproduction is as good as some of this year’s best TVs.

Not only does it have some smart-looking specs under its belt, it has some killer additional features — there’s two HDMI 2.1 ports that support 4K@120Hz and on-board Google TV 11 with Chromecast Built-in. Around back you’ll find a hefty sound system that delivers bass in spades, though it could be a bit stronger in the mid-range. Of course, there"s also an ATSC 3.0 tuner inside, too.

The LG G1 OLED TV is the updated version of LG"s superb Gallery GX OLED, boasting a premium 20 millimeter-thick design and sleek flush-to-the-wall mounting setup. A lot goes unchanged, like the impressive profile and built-in ATSC 3.0 tuner. The design is impeccable – enough to win best TV design in the 2021 Tom"s Guide Awards. It"s still the best 4K OLED TV we"ve seen from LG, but as the first TV with LG"s second-gen OLED evo technology, our tests found it falls short of some claimed performance improvements we were pretty excited for.

That said, the LG G1 OLED is still an impressive OLED set, and LG has even knocked the price down a bit, while updating almost everything else about the set. The slim OLED features more comfortable remote control, enhanced gaming features, and the latest version of webOS, all while delivering the same excellent picture quality and impeccable sound that we expect from LG"s best OLED models. The LG G1 OLED TV stands as a reminder of just how far modern TV technology has come — we just hope it hasn’t plateaued.

NextGen TV is the marketing name for the new ATSC 3.0 broadcast standard, which combines traditional over-the-air broadcasting and improved digital signal encoding with internet connectivity, opening up all sorts of possibilities that were previously unimagined for free broadcast television. (Read our full article ATSC 3.0 explained: How NextGen TV delivers 4K HDR broadcasts for free to learn more.)

Better signal quality with less interferenceThanks to a move toward UHF signal, it"s less prone to interference from obstructions, like buildings or trees, and adds orthogonal frequency-division multiplexing (OFDM), the same technology behind the latest Wi-Fi and mobile wireless technologies. It"s a much more robust method for transmitting digital information, and the move will further bolster the signal quality with ATSC 3.0.

Higher resolution for over-the-air broadcastWith a bitrate of up to 57 Mbps – nearly three times as much as the older ATSC 1.0 standard – and support for H.265 and MPEG-H Part 2 codecs, the new standard can deliver much higher video quality, including HDR metadata. Broadcasts in 4K resolution are already possible, with potential for 8K broadcasts in the future.

Combines broadcast TV with broadband internetThis leverages the connected nature of smart TVs to have a dedicated return channel – an active stream of data back to the broadcaster – which makes the new broadcast system a two-way IP-based standard. That could allow broadcasters to pair their traditional content with streaming capabilities, allow for cloud DVR functions, video-on-demand and more targeted advertising.

Available on many more devicesThanks to the more robust signal quality and the data-connected aspects of the new standard, it will offer better reception for portable and vehicle-bound TVs – two categories that have fallen off sharply since the more fragile digital TV of the ATSC 1.0 standard took effect. You could even get ATSC 3.0 on your phone, provided phone makers opt to add the necessary hardware.

At the moment, probably not. NextGen TV is still early in its rollout, and any stations you might be able to get with the new tuner you can get on the older ATSC 1.0 standard anyway.

But, if you want the potential to receive 4K signals over the air, or to take advantage of any of the proposed features that are likely to be implemented as NextGen TV rolls out, you will need a new tuner.

In our TV test space, we submit every TV to a number of lab tests, using industry-standard equipment, such as a calibrated spectrophotometer, calibration software and a dedicated test pattern generator. We measure for several indicators of picture quality, but these are the main metrics used in all of our reviews:

Color gamut, which measures how much color a given TV can produce. Expressed as a percentage rating, most OLED TVs meet or exceed 100% of the Rec709 color space.

Lag time is the interval between a signal, such as button press on a game console, and the subsequent change registering on-screen. Measured with a Leo Bodnar Video Signal Input Lag Tester, this is measured in milliseconds, and provides a good indicator of how well-suited a TV is to modern gaming.

We pair this lab testing with hands-on time, viewing video samples and movies to see how these numbers translate into real-world performance. With that information, we can tell you which TVs look best, sound best and offer the best viewing experience.

Finally, we also evaluate the smart TV software and menus, getting a feel for the navigation and functions of each TV. We look at everything from the remote control design to the voice interaction to let us meaningfully talk about the smart features and overall ease-of-use for a smart TV.

NextGen TV, aka broadcasts later this year. While not every station in every market has a NextGen TV counterpart, more and more are coming on the air.

What"s NextGen TV? It"s an update to the free HDTV you can already get over-the-air in nearly every city in the US. There"s no monthly fee, but you do need either a

It"s not backwards-compatible with the current HD standard (ATSC 1.0), so your current TV won"t be able to receive it. Your current antenna should work fine though.

Put simply: If you connect an antenna to your TV you will receive free programming, just like most people can get now. Yet, that is selling the potential benefits of NextGen TV short.

NextGen TV is IP-based, so in practice it can be moved around your home just like any internet content can right now. For example, you connect an antenna to a tuner box inside your home, but that box is not connected to your TV at all. Instead, it"s connected to your router. This means anything with access to your network can have access to over-the-air TV, be it your TV, your phone, your tablet or even a streaming device like

This also means it"s possible we"ll see mobile devices with built-in tuners, so you can watch live TV while you"re out and about, like you can with Netflix and YouTube now. How willing phone companies will be to put tuners in their phones remains to be seen, however. You don"t see a lot of phones that can get radio broadcasts now, even though such a thing is easy to implement. We"ll talk more about that in a moment.

In November of 2017, the Federal Communications Commission approved ATSC 3.0 as the next generation of broadcast standard, on a "voluntary, market-driven basis" (PDF). It also required stations to continue broadcasting ATSC 1.0 (i.e. "HD"). This is actually part of the issue as to why it"s voluntary.

While it"s not a mandatory standard, many broadcasters still seem enthusiastic about NextGen. At the beginning of the roll-out, then executive vice president of communications at the National Association of Broadcasters Dennis Wharton told CNET that the improvement in quality, overall coverage and the built-in safety features mean that most stations would be enthusiastic to offer ATSC 3.0.

One of NextGen TV"s more controversial features is a "return data path," which is a way for the station you"re watching to know you"re watching. Not only does this allow a more accurate count of who"s watching what shows, but it creates the opportunity for every marketer"s dream: targeted advertising.

Ads specific to your viewing habits, income level and even ethnicity (presumed by your neighborhood, for example) could get slotted in by your local station. This is something brand-new for broadcast TV. Today, over-the-air broadcasts are pretty much the only way to watch television that doesn"t track your viewing habits. Sure, the return data path could also allow "alternative audio tracks and interactive elements," but it"s the targeted ads and tracking many observers are worried about.

Return data path is still in the planning stages, even as the other aspects of NextGen TV are already going live. There is a silver lining: There will be an opt-out option. While it also requires Internet access, if this type of thing bothers you, just don"t connect your TV or NextGen TV receiver to the internet. You will inevitably lose some of the other features of NextGen TV, however.

Another point of potential contention is getting ATSC 3.0 tuners into phones. At a most basic level, carriers like AT&T, Verizon and T-Mobile are in the business of selling you data. If suddenly you can get lots of high-quality content for free on your phone, they potentially lose money. Ever wonder why your phone doesn"t have an FM radio tuner?

T-Mobile made a preemptive strike along those lines all the way back in September 2017, writing a white paper (PDF) that, among other things, claims, "In light of the detrimental effects that inclusion of ATSC 3.0 can have on the cost and size of a device, the technology trade-offs required to accommodate competing technologies, and the reduced performance and spectral efficiency that it will have for other mobile bands and services, the decision as to whether to include ATSC 3.0 in a device must be left to the market to decide."

TV broadcasters, on the other hand, are huge fans of ATSC 3.0 on mobile phones. It means more potential eyeballs and, incidentally, a guarantee of active internet access for that return data path. John Hane of the Spectrum Consortium feels that tuners built into phones is "inevitable," and that international adoption of ATSC 3.0 will help push it forward. Wharton says that the focus is getting TVs to work, but mobile is in the plan.

Here"s the actual language:"The programming aired on the ATSC 1.0 simulcast channel must be "substantially similar" to the programming aired on the 3.0 channel. This means that the programming must be the same, except for programming features that are based on the enhanced capabilities of ATSC 3.0, advertisements and promotions for upcoming programs. The substantially similar requirement will sunset in five years from its effective date absent further action by the Commission to extend it."

Here"s another way to think about it: The first HD broadcasts began in the mid-90s, but when did you buy your first HDTV? As far as the 3.0 transition is concerned we"re in the late-90s, maybe generously the early 2000s, now. Things seem like they"re moving at a much more rapid pace than the transition from analog to DTV/HDTV, but even so, it will be a long time before ATSC 3.0 completely replaces the current standard.

If you want to check it out for yourself, many of you already can. The first stop is to go to WatchNextGenTV.com. That website will help you find what stations in your area are broadcasting, or which ones will soon.

Next up you"ll need something to receive it. If you"re in the market for a new TV there are several options available from Hisense, LG, Samsung, and Sony. Here"s our list of

Then there"s what to watch. Being early in the process, you"re not going to find much 4K content, possibly not any. This was the same with the early years of HDTV. It"s also going to vary per area. There is certainly a lot of 4K content being produced right now, and that has been the case for several years. So in that way, we"re in better shape than we were in the early days of HD.

One company is using the bandwidth and IP nature of NextGen to do something a little different. It"s a hybrid paid TV service, sort of like cable/satellite, but using over-the-air broadcasts to deliver the content. It"s called

But technology moves faster and faster. It"s highly doubtful it will take 16 years to fully implement NextGen TV. As we mentioned at the top, dozens of stations are already broadcasting. Will every station in your city switch to NextGen TV? Probably not, but the bigger ones likely will. This is especially true if there are already other NextGen TV stations in your area. There"s a potential here for stations to make additional money in the long run with 3.0, and that"s obviously a big motivator.

There"s also the question of how much content there will be. If it follows the HDTV transition model, big sporting events in 4K HDR will come first, followed by lots and lots of shows featuring nature scenes and closeups of bugs. Seriously -- this was totally a thing. Then we"ll see a handful of scripted prime-time shows. My guess would be the popular, solidly profitable ones that are produced (not just aired) by networks like CBS and NBC.

So should you hold off buying a new TV? Nope, not unless you only get your shows over the air. And even if you do, by the time there"s enough content to be interesting, there will be cheap tuner boxes you can connect to whatever TV you have.
