Tv on 4k for Computer Monitor, Can't Read Anything
Our Experts Have Tested 35 Products in the Monitors Category in the Past Year
Since 1982, PCMag has tested and rated thousands of products to aid you brand ameliorate buying decisions. (See how we exam.)
Whether information technology'due south for gaming, office productivity, or creative work—or just to stream your favorite movies—a 4K monitor is a must-have upgrade for some shoppers. Merely the 4K monitors on the market today are far from alike. Some are congenital to evangelize speedy refresh rates to benefit PC gamers. Others are designed for graphics pros, with extreme color accuracy and support for wide color ranges in heed. And selected models pack workflow-enhancing features that tin make managing your desktop much easier.
Here's everything you demand to know about the benefits (and possible pitfalls) of getting a new 4K panel today. Nosotros've too ranked the 4K monitors that have made the cut according to our detailed testing. They're a bang-up starter set up for your search.
Get-go Off: Do Y'all Even Need a 4K Monitor?
Permit'southward ascertain 4K first. The vast majority of 4K monitors are displays with a native resolution of 3,840 pixels across by 2,160 pixels on the vertical. That's four times every bit many equally a ane,920-by-1,080-pixel monitor—and that'due south a lot of pixels. Some other resolutions with approximately 4,000 horizontal pixels—nearly normally 4,096 past two,160—are too considered 4K. All these panels remain a premium option, but they are becoming increasingly common on desks at work, at home, or in gamers' frag dens.
But before we get too deep into the topic, we should first assistance you respond a key question: Is a 4K monitor right for you in the starting time place? Depending on what you do most with your monitor, and where you'll place it, the extra money you'd pay versus a lower-resolution brandish may not be necessary.
To 4K or Not to 4K: That is the Gamer'southward Dilemma
For starters, if yous want a 4K monitor solely for amusement purposes that don't heart on PC gaming, a 4K Boob tube would likely be a cheaper choice. That's because many 4K TVs aren't beholden to the same standards that 4K monitors are, such as the need for boosted refresh rates (for gaming models), high-level or specialized color accurateness (for content-artistic ones), or low levels of input lag. (Run across our picks for the best TVs, at present uniformly 4K models.)
Allow'due south have gaming. While gorgeous to look at, gaming in 4K with modern games requires loads of graphics horsepower to get in a higher place 60 frames per second (fps), today'due south mostly acknowledged minimum for serious gamers. Right now, merely a scattering of graphics cards can reliably power a 4K screen with leading-edge, AAA game titles at top settings. And you'd want to creepo everything upwardly to make the 4K investment worthwhile. (If you're turning downwards the particular settings in a game to make it run amend in 4K, that defeats much of the point of 4K in the first place.)
These elite cards include models like Nvidia'due south GeForce RTX 3080, GeForce RTX 3090, GeForce RTX 2080, as well equally AMD'due south Radeon RX 6800 and RX 6700 serial—all of them expensive video cards with prices greatly inflated of late. If you don't have ane, gaming at 4K is going to demand compromises—and it may not be worth the splurge.
Gaming at 4K isn't all about your hardware these days, though. A armada of software technologies (epitome sharpeners, upscalers, and supersamplers) from both AMD and Nvidia have hit the market to come across 4K-play need in recent years. In a nutshell, these technologies aim to allow PCs with video cards, PCs relying on lesser integrated graphics, and panel-based GPUs all to run at higher resolutions without the associated functioning cost, with as little visible loss in quality as possible. While they may not exist "truthful 4K" gaming, to my eyes and many more than, they're the best that owners of game consoles and midrange graphics cards can practise until hardware prices come downwards again.
The full list of software and its supported platforms, hardware, and games tin can and has seen some of its own articles already, and so we won't slow downwards to go over the nuances here. But if 1 of those scenarios fits your needs, the next pace is to figure out whether or not a 4K monitor is right for y'all for unlike reasons: your desk configuration, and your eyesight.
Side by side Question: Tin You Meet in 4K?
With TVs, the reply to whether or not yous should opt for a 4K model today is almost always "aye," considering information technology's difficult to find new, non-4K models these days, anyway. It'southward not quite every bit simple with 4K monitors. If y'all get really serious nearly that question in the monitor world, it comes downwards to algebra, and it raises bug like pixel pitch, pixels per inch (ppi), and "angular resolutions." Let's keep information technology simple, though.
A good example of the pixel-pitch problem arises in VR headsets, with an issue known every bit the "screen door" consequence. In essence, the lower the maximum resolution that a screen is capable of displaying, and the closer you sit to the screen, the easier it is to see its individual pixels. In the instance of VR headsets, it makes the image await equally though it's beingness seen through mesh, and information technology'southward why VR headsets have seen resolution upticks in successive models. When something's that close to your eyes, you can more than clearly run across the divergence.
The same issues apply to monitors, just across a larger viewing altitude than inches from your optics. The tricky bit is that viewing distance isn't stock-still; it depends on the size and layout of your desk, your chair position, and so on. Whether you can brand out the difference in resolution on a 4K panel versus, say, a 1440p ane (that's 2,560 by one,440 pixels) depends on your eyesight, that viewing altitude, and the screen size. The screen size, at a 4K resolution, calculates out to a certain number of ppi, in essence the pixel density of the screen. You can see how information technology scales here at each common resolution...

Lucky for us, we don't have to do any of the hard math on our own. The team over at Puget Systems has designed a helpful Google Sheet that will automatically help you lot figure out the optimal display size and resolution for you, depending on your personal level of visual acuity. All you lot have to practice is plug in your target screen size and resolution, the distance from the panel to your eyes, and the specifics of your eyesight. Y'all tin and then effort dissimilar numbers and see how the output changes, helping you figure out if a sure screen size or viewing distance makes more or less sense. (If you haven't been to the middle doctor lately and don't know your prescription forcefulness, a few more than hand calculations, using some of the formulas on this page, are all you need.)
Of course, less scientifically, yous can also look at 4K panels of diverse screen sizes in a local store to encounter if you tin tell the difference between them and 1440p or 1080p ones of similar screen sizes. Simply you lot'll desire to observe the aforementioned screen prototype, scaled the same amount, to see a meaningful comparison, and that may not always be practical.
Nevertheless, to summarize: Before you purchase a 4K monitor, make sure yous'll actually be able to see the do good of the increased pixel density in your particular seating setup. Take 20/15 vision, already ain a 27-inch, 2,560-past-one,440-pixel (1440p) monitor, and will sit three feet from the screen? A 4K monitor probably won't offering a large enough boost in clarity to justify the cost at the aforementioned screen size and distance. It all depends on how large your 4K console is, how close or how far you'll sit, and your eyesight.
What Screen Type of 4K Monitor Should You Buy?
Before you buy a new 4K monitor, you lot should know the benefits and drawbacks of the different brandish technologies that power them. Well-nigh of the time, information technology's piece of cake to notice what kind of panel a given 4K monitor has simply past looking at the manufacturer spec sheet. Allow'due south run through the most common kinds.
VERTICAL ALIGNMENT (VA). VA panels are some of the oldest in the game. Only they're still effectually considering, despite meliorate display technologies coming along since, they "simply work." VA panels offer some of the highest contrast ratios exterior of OLED ones (more than about which in a moment), and they also offer better viewing angles and color reproduction than TN panels. However, they're besides the slowest of all the display technologies, offering the pokiest response times and input-lag numbers of the agglomeration. That makes them subpar for gaming.
TWISTED NEMATIC (TN). TN displays, on the other hand, are extremely fast in terms of pixel response, averaging anywhere between 1-millisecond (ms) and 5ms response times, and they are relatively inexpensive to produce versus other panel types, making them ideal for gamers. The tradeoffs with TN, however? Uneven color product, limited off-center viewing angles, and wearisome contrast ratios. That's quite a flake to give up in the proper noun of speed, which ways that you lot'll typically see 4K TN displays but in gamer-centric models.
IN-PLANE SWITCHING (IPS). IPS panels are common in the world of 4K displays. They tend to be slightly more than expensive to produce than VA or TN panels, simply they offer the best "all-effectually" experience for most users: stiff color reproduction, moderately quick response times, and the widest viewing angles of any display type exterior of OLED. This comes at a price, though, with IPS models costing anywhere from $50 to $300 more than than their equivalent non-IPS counterparts at a given screen size.
A host of IPS monitors launched in 2021 and into 2022 with a tweaked panel blazon, Nano IPS or Fast IPS. The proper name varies, only this new kind of IPS adds to the gaming capabilities and overall colour vividness in near of the units we've tested so far. There are still some fluke entries, but overall Nano IPS/Fast IPS is the preferred selection for anyone who wants polish motion, low response times, and low input lag values in their adjacent display.
ORGANIC Low-cal-EMITTING DIODE (OLED). OLED is the newest brandish technology in stand-alone monitors. Offering a theoretically infinite dissimilarity ratio, gorgeous color for moving picture and TV, and superb black levels for gaming in dark scenarios, OLED sounds similar a great display technology that every monitor manufacturer should be pumping out in droves, and in the OLED Television set samples we've seen, it looks stupendous.
But although 4K OLED panels have been all the rage for several years now in the TV market (and are starting to brand their mode into laptop displays), we haven't seen a single OLED desktop computer monitor released outside of the professional-level Asus ProArt PQ22UC, a 21.6-inch 4K panel at $three,999, and the much bigger Alienware 55 OLED. In the case of the latter, due to OLED's burn down-in potential and issues with effulgence, we rated this "monitor" as more of an OLED Idiot box that happens to run at 120Hz, rather than a panel yous'd be likely to use as your desktop'due south daily driver.
MINI LED. Finally, there's mini LED. Rather than edge-lighting an LCD-based panel with a ring of LEDs that sit down effectually the display and light the moving-picture show globally, mini LED embeds hundreds, even thousands, of pocket-size LEDs behind the console itself. This allows for a lighting technique known as "full-array local dimming" (or FALD) to work. For now, it allows for the closest you tin become to OLED's infinite contrast without having to actually spend the coin that OLED displays need.
As of this writing, only a handful of desktop monitors support mini LED technology (Dell's UltraSharp 32 HDR PremierColor Monitor and the Asus ProArt PA32UCX amongst them, along with an Asus ROG Swift model for gamers, the PG32UQX), though that will change in the coming years.
The Real Gaming Aristocracy: Special Considerations in 4K
Though 4K displays are however far from the norm in the gaming-monitor market, the top models are adopting rapid pixel-response times and blisteringly quick refresh rates. Every bit the technologies in the panels (and the GPUs needed to ability them properly) advance ever forward, what are the master features that a potential 4K gamer needs to keep an eye out for? Allow's lay them out.
INPUT LAG. In broad strokes, input lag is measured as the amount of time it takes for your monitor to display an external action. For case, if I click a push button on my mouse, the input-lag number (measured in milliseconds) expresses how long it took for the click to appear as an onscreen action. Some of the all-time gaming monitors out there can accomplish input-lag figures below 2ms, though this often is slower in 4K displays, only because the number of pixels being drawn by the display on each laissez passer is greater than it would be on a lower-resolution monitor.
REFRESH Rate. Refresh rates are where things have really kicked into loftier gear over the past few years, peculiarly on monitors with native resolutions below 4K. Lower-resolution monitors take been pushing rapidly from 60Hz (the standard in everyday displays for ages) to 144Hz, 144Hz to 165Hz, and all the manner upwards to 240Hz or even 360Hz in certain esports-focused models.
Like so much else, it's more complicated with 4K. Due to the bandwidth limits of the HDMI ii.0 and DisplayPort 1.4b interfaces and their cables, early on 4K monitors were limited to just 60Hz. In the by year, however, several models that utilize HDMI 2.1 have been released that push that ceiling as high as 120Hz.
Also in that illustrious visitor are the HP Omen X65 Emperium (the beginning Nvidia "Large Format Gaming Display," or BFGD), and the Asus PG27UQ. How practise they do it? With a technique called "chroma subsampling," which y'all can read more nearly in our breakdown of the challenges and pitfalls of gaming at 4K and 144Hz.
RESPONSE Time. Not to be confused with input lag, response fourth dimension refers to the amount of time it takes for a pixel to alter from black to white, or from ane shade of gray to another. In practical terms, you lot should wait a response time of less than 20ms in fifty-fifty the slowest 4K panels, and when shopping for a gaming console in particular, it's improve to aim for 5ms or lower to keep yourself competitive in the long term.
ADAPTIVE-SYNC TECH. Nvidia K-Sync, AMD FreeSync, and AMD FreeSync2 are all flavors of what are known every bit "adaptive sync" technologies. Without getting likewise deep in the weeds, all three are designed to prevent screen tearing (that is, screen draws with parts of the image misaligned) and stuttering. These maladies can happen on monitors—gaming-focused or otherwise—in scenes with lots of fast-moving action.
They accomplish this by aligning the refresh rate of the monitor on the fly with the frame-charge per unit output of the video card, only drawing a frame when a full 1 is delivered, rather than at a fixed charge per unit. Though adaptive sync is non essential for gamers who mostly play single-player, slow-paced titles, it's great for anyone taking his or her skills into the online multiplayer arena in serious, competitive fashion.
Note that you lot need a uniform graphics card to piece of work with Thou-Sync or FreeSync. Grand-Sync requires a compatible Nvidia GeForce card (all late-model cards support it), and FreeSync needs an AMD Radeon RX i. Notation that a relatively new subset of monitors, dubbed Chiliad-Sync Uniform, have been designated by Nvidia to likewise work with the adaptive-sync tech on its cards despite non having the specific and exclusive G-Sync-enabling circuitry of earlier One thousand-Sync monitors.

Creating in 4K: Pro Graphics Panels
Seeing equally the monitor industry is ramping up the movement toward 4K, and consumers are adding millions of them to their desks, content creators need to be able to master their creations in 4K too, right? This is where professional person 4K monitors come up in.
Professionals were among the start folks to get monitors that featured true 4K-pixel-count panels, and these buyers continue to bulldoze the market place forward with 5K, 6K, and even 8K monitors peeking out just over the horizon.
A 4K monitor is a nice add-on to any amateur or professional creator's arsenal, though it should be noted that in terms of color reproduction or accuracy, in that location'due south aught inherently better well-nigh 4K monitors than 1440p or 1080p displays. Instead, the main benefit is for those who work in high item, notably in photography, 3D visual arts, or cinematography. In those areas, having more than pixels to work with gives you a greater level of accuracy, whether you're drawing angel wings on an paradigm of a model, creating vector art, mastering a moving-picture show, or doing annihilation that requires zooming in and retaining every bit much visual fidelity as possible.
Another benefit is simply sheer workspace. Even if your ultimate output isn't in 4K, working on a 4K console can let yous await at your content at total target resolution while leaving screen space for palettes, command menus, timelines, and other creation tools. Of course, you lot could relegate that stuff to a 2d monitor if you need the infinite, merely a 4K panel can enable single-display workflows that were not possible or simply were more than bad-mannered earlier.
Colour-gamut coverage is a key specification for many folks in this space. A number of 4K professional monitors achieve industry specifications of covering 100% of sRGB, too as potent results with the Adobe RGB and DCI-P3 colour gamuts. Practiced examples of these panels that we have tested include the NEC MultiSync PA311D-BK, the Dell UltraSharp 27 4K PremierColor (UP2720Q), the BenQ EW3270U, and the ViewSonic VP2785-4K.
4K for the Function: Panels With Productivity Features
Keeping busy on a 4K monitor isn't much different from doing full general piece of work on a monitor of a lesser resolution, but for 1 central deviation: effective screen infinite. Because a 4K monitor has four times the available pixels than a 1080p monitor, this gives you, in theory, 4 times as much elbow room to mountain windows next.
The reason we say "in theory"? The thought is sound, but in do information technology's almost impossible to make out the aforementioned text scaled 1:1 in 4K versus 1080p at the same screen size. This is why both Windows and Mac machines come with a feature known as "DPI scaling" (DPI being brusk for "dots per inch"). For example, when you switch your resolution from 1080p to 4K in Windows x, by default Windows 10 will machine-scale your content to 150% of its standard DPI.
This increases the size of all rendered elements on the screen past that pct. At 150% scaling, it's more likely that you lot'd be able to fit two or 3 standard browser windows adjacent and nonetheless clearly read their text. With four windows, 1 per corner of the screen? Not then likely.
To help simplify your workflow even more, some 4K monitors, such as the business-centric Dell U3219Q pictured above, come with built-in features similar an automatic window-sizing tool. (It sections off parts of your screen that programs in Windows volition resize to on their own.) Similarly, these monitors can accept video signals from multiple sources and brandish them side past side ("picture by picture") or inlaid in a larger window ("picture in picture"). This can be useful, say, if you lot accept a PC that you're developing on, but you need to test your changes in your plan on a separately connected Mac at the same time.
Connections, Adjustments, and HDR
Some specs are not as front-and-center as the brandish type or the refresh charge per unit, but they will touch on how you piece of work with your 4K display day to solar day.
The stand up's allowable adjustability might seem trivial, merely it can affect your comfort, depending on where and how you lot employ your panel. A range of tilt is pretty standard (unremarkably, the monitor maker will express it in degrees forward and back), but you'll desire to look for the ability to hinge the panel left and right on its stand or rotate it betwixt mural and portrait modes. (The latter is uncommon and mostly for serious photo editors.)
Connectivity is another thing to bank check, though for nigh folks, it comes down to an HDMI or DisplayPort input, and near 4K panels will take both, sometimes several. Watch for a match with your video source. A few panels back up input via Thunderbolt 3, suited for input from certain laptops, notably late-model MacBook Pros. A few nongaming models in contempo months have ditched HDMI and DisplayPort altogether in favor of Thunderbolt three exclusively.
One note: To go a 4K display running higher up the 60Hz refresh-rate threshold (by and large of involvement to gamers or game developers), you demand a video card capable of outputting its signal over a DisplayPort 1.4b cable, and with some 4K 144Hz monitors (such as the Acer Nitro XV273K), yous'll need 2 such connections plugged in concurrently.
Finally, at that place'due south the upshot of HDR. High-dynamic range is a color specification common on modern 4K TVs, but information technology has made inroads into monitors over the past few years. (Meet our HDR primer for much more background on it.) Of form, y'all'll need media recorded in HDR, or games that support the HDR spec, in order to relish it.
That said, if you accept a monitor that also plugs into an Xbox One X, for example, that console volition brandish all kinds of HDR content as a plug-and-play feel without issue.
So, Which 4K Monitor Should I Buy?
Upgrading to a 4K monitor, as yous can see, entails a lot more than only a simple resolution uptick. But now, armed with our overview, it'due south time to store. Nosotros've tested a host of 4K monitors out there and pulled out a selection of the very all-time that represents all the main usage classes: business-facing monitors, gaming ones, and artistic/professional panels. Let's dig in...
