Our Experts Have Tested 29 Products in the Monitors Category in the Past Yr
Since 1982, PCMag has tested and rated thousands of products to aid you brand better buying decisions. (See how we test.)
Whether it's 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. But the 4K monitors on the market today are far from alike. Some are built to deliver speedy refresh rates to benefit PC gamers. Others are designed for graphics pros, with extreme colour accurateness and support for broad colour ranges in listen. And selected models pack workflow-enhancing features that can brand managing your desktop much easier.
Here'south everything you need to know near the benefits (and possible pitfalls) of getting a new 4K panel today. We've as well ranked the 4K monitors that have fabricated the cut according to our detailed testing. They're a great starter set for your search.
First Off: Practise You Even Need a 4K Monitor?
Permit's ascertain 4K first. The vast majority of 4K monitors are displays with a native resolution of three,840 pixels beyond by ii,160 pixels on the vertical. That'due south 4 times as many as a i,920-by-one,080-pixel monitor—and that's a lot of pixels. Some other resolutions with approximately 4,000 horizontal pixels—nearly commonly 4,096 past 2,160—are also considered 4K. All these panels remain a premium selection, but they are becoming increasingly common on desks at work, at dwelling house, or in gamers' frag dens.
But before we become too deep into the topic, we should first help you respond a fundamental question: Is a 4K monitor right for y'all in the start place? Depending on what you practice most with your monitor, and where you'll identify it, the extra money you'd pay versus a lower-resolution display 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 entertainment purposes that don't center on PC gaming, a 4K TV would likely exist a cheaper pick. That's because many 4K TVs aren't appreciative to the same standards that 4K monitors are, such equally the demand for boosted refresh rates (for gaming models), high-level or specialized colour accuracy (for content-artistic ones), or low levels of input lag. (See our picks for the best TVs, now uniformly 4K models.)
Permit'due south have gaming. While gorgeous to look at, gaming in 4K with modern games requires loads of graphics horsepower to get above 60 frames per second (fps), today'southward generally best-selling minimum for serious gamers. Right at present, but a scattering of graphics cards can reliably power a 4K screen with leading-edge, AAA game titles at top settings. And y'all'd want to creepo everything up to make the 4K investment worthwhile. (If you're turning downwardly the detail settings in a game to make it run better in 4K, that defeats much of the point of 4K in the first place.)
These elite cards include models like Nvidia's GeForce RTX 3080, GeForce RTX 3090, GeForce RTX 2080, as well as AMD'south Radeon RX 6800 and RX 6700 series—all of them expensive video cards with prices greatly inflated of late. If you don't accept ane, gaming at 4K is going to demand compromises—and it may not be worth the splurge.
Gaming at 4K isn't all nearly your hardware these days, though. A armada of software technologies (prototype sharpeners, upscalers, and supersamplers) from both AMD and Nvidia take striking the market place to meet 4K-play demand in recent years. In a nutshell, these technologies aim to permit PCs with video cards, PCs relying on lesser integrated graphics, and console-based GPUs all to run at college resolutions without the associated operation cost, with as piffling visible loss in quality as possible. While they may not be "truthful 4K" gaming, to my optics and many more, they're the all-time that owners of game consoles and midrange graphics cards tin practise until hardware prices come up down once more.
The full list of software and its supported platforms, hardware, and games can and has seen some of its own articles already, and so we won't slow down to become over the nuances here. Just if i of those scenarios fits your needs, the next stride is to figure out whether or not a 4K monitor is correct for you for dissimilar reasons: your desk configuration, and your eyesight.
Next Question: Can You Come across in 4K?
With TVs, the answer to whether or not you should opt for a 4K model today is almost ever "aye," because information technology's difficult to find new, non-4K models these days, anyway. It's not quite as simple with 4K monitors. If you get really serious nigh that question in the monitor world, it comes down to algebra, and it raises problems similar pixel pitch, pixels per inch (ppi), and "angular resolutions." Let's continue it uncomplicated, though.
A skillful example of the pixel-pitch problem arises in VR headsets, with an effect known as the "screen door" outcome. In essence, the lower the maximum resolution that a screen is capable of displaying, and the closer you sit down to the screen, the easier it is to see its individual pixels. In the case of VR headsets, it makes the epitome look as though it's being seen through mesh, and it's why VR headsets accept seen resolution upticks in successive models. When something's that shut to your eyes, you lot can more conspicuously run across the difference.
The same issues utilize to monitors, just across a larger viewing distance than inches from your eyes. The tricky bit is that viewing distance isn't fixed; it depends on the size and layout of your desk, your chair position, and so on. Whether you can make out the deviation in resolution on a 4K console versus, say, a 1440p one (that'south 2,560 by ane,440 pixels) depends on your eyesight, that viewing distance, 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. Y'all can see how it scales hither 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 Sail that will automatically assist you figure out the optimal display size and resolution for you, depending on your personal level of visual acuity. All you lot have to do is plug in your target screen size and resolution, the altitude from the panel to your eyes, and the specifics of your eyesight. You lot tin and so endeavor different numbers and see how the output changes, helping y'all figure out if a certain screen size or viewing altitude makes more or less sense. (If y'all haven't been to the eye physician lately and don't know your prescription strength, a few more hand calculations, using some of the formulas on this page, are all you demand.)
Of course, less scientifically, yous tin as well wait at 4K panels of diverse screen sizes in a local store to come across if you can tell the difference between them and 1440p or 1080p ones of like screen sizes. But yous'll want to discover the same screen image, scaled the same amount, to run into a meaningful comparing, and that may non ever be practical.
Still, to summarize: Before yous buy a 4K monitor, make sure you'll really be able to see the do good of the increased pixel density in your particular seating setup. Have 20/15 vision, already own a 27-inch, 2,560-by-1,440-pixel (1440p) monitor, and volition sit down three feet from the screen? A 4K monitor probably won't offer a large enough heave in clarity to justify the cost at the same screen size and distance. It all depends on how big your 4K console is, how shut or how far yous'll sit, and your eyesight.
What Screen Blazon of 4K Monitor Should Y'all Buy?
Before yous buy a new 4K monitor, you should know the benefits and drawbacks of the different display technologies that power them. Nigh of the time, it'due south like shooting fish in a barrel to find what kind of panel a given 4K monitor has merely by looking at the manufacturer spec sheet. Permit'due south run through the nigh common kinds.
VERTICAL ALIGNMENT (VA). VA panels are some of the oldest in the game. Only they're even so around because, despite better display technologies coming along since, they "simply work." VA panels offer some of the highest dissimilarity ratios outside of OLED ones (more most which in a moment), and they too offer meliorate viewing angles and color reproduction than TN panels. However, they're also the slowest of all the display technologies, offering the pokiest response times and input-lag numbers of the bunch. 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, withal? Uneven color production, limited off-center viewing angles, and ho-hum contrast ratios. That'south quite a bit to give up in the name of speed, which ways that y'all'll typically run into 4K TN displays only in gamer-centric models.
IN-PLANE SWITCHING (IPS). IPS panels are common in the world of 4K displays. They tend to exist slightly more expensive to produce than VA or TN panels, but they offering the best "all-around" feel for well-nigh users: potent color reproduction, moderately quick response times, and the widest viewing angles of any display type outside of OLED. This comes at a price, though, with IPS models costing anywhere from $50 to $300 more 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 type, Nano IPS or Fast IPS. The proper noun varies, but this new kind of IPS adds to the gaming capabilities and overall colour vividness in well-nigh of the units we've tested and then far. There are still some fluke entries, simply overall Nano IPS/Fast IPS is the preferred pick for anyone who wants smooth move, low response times, and low input lag values in their next display.
ORGANIC LIGHT-EMITTING DIODE (OLED). OLED is the newest display applied science in stand-alone monitors. Offer a theoretically infinite contrast ratio, gorgeous color for film and Idiot box, and superb black levels for gaming in night scenarios, OLED sounds like a great brandish technology that every monitor manufacturer should exist pumping out in droves, and in the OLED TV samples nosotros've seen, it looks stupendous.
Just although 4K OLED panels have been all the rage for several years now in the TV market (and are starting to make their way 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 $3,999, and the much bigger Alienware 55 OLED. In the case of the latter, due to OLED's burn-in potential and problems with brightness, we rated this "monitor" every bit more of an OLED TV that happens to run at 120Hz, rather than a console you lot'd exist likely to use as your desktop's daily commuter.
MINI LED. Finally, there's mini LED. Rather than border-lighting an LCD-based panel with a ring of LEDs that sit around the display and light the movie globally, mini LED embeds hundreds, even thousands, of modest LEDs behind the panel itself. This allows for a lighting technique known every bit "total-array local dimming" (or FALD) to work. For now, it allows for the closest you tin get to OLED's infinite contrast without having to actually spend the money that OLED displays demand.
Every bit 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 among them, along with an Asus ROG Swift model for gamers, the PG32UQX), though that will modify in the coming years.
The Existent Gaming Elite: Special Considerations in 4K
Though 4K displays are still far from the norm in the gaming-monitor market, the top models are adopting rapid pixel-response times and blisteringly quick refresh rates. As the technologies in the panels (and the GPUs needed to power them properly) advance ever forward, what are the primary features that a potential 4K gamer needs to go along an eye out for? Let's lay them out.
INPUT LAG. In broad strokes, input lag is measured every bit the amount of time it takes for your monitor to display an external action. For example, if I click a button on my mouse, the input-lag number (measured in milliseconds) expresses how long it took for the click to announced as an onscreen activity. Some of the best gaming monitors out in that location tin can achieve 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 information technology would be on a lower-resolution monitor.
REFRESH Charge per unit. Refresh rates are where things have really kicked into high gear over the by few years, especially 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 way up to 240Hz or fifty-fifty 360Hz in sure esports-focused models.
Similar and then much else, it'south more complicated with 4K. Due to the bandwidth limits of the HDMI 2.0 and DisplayPort 1.4b interfaces and their cables, early on 4K monitors were limited to only 60Hz. In the past year, however, several models that utilize HDMI 2.1 have been released that push that ceiling every bit high as 120Hz.
As well in that illustrious company are the HP Omen X65 Emperium (the first Nvidia "Large Format Gaming Display," or BFGD), and the Asus PG27UQ. How practise they practice it? With a technique called "chroma subsampling," which you can read more than about in our breakdown of the challenges and pitfalls of gaming at 4K and 144Hz.
RESPONSE TIME. Not to be dislocated with input lag, response time refers to the amount of time it takes for a pixel to modify from blackness to white, or from one shade of grey to another. In practical terms, you should expect a response time of less than 20ms in fifty-fifty the slowest 4K panels, and when shopping for a gaming panel in particular, information technology's better to aim for 5ms or lower to keep yourself competitive in the long term.
ADAPTIVE-SYNC TECH. Nvidia Thousand-Sync, AMD FreeSync, and AMD FreeSync2 are all flavors of what are known every bit "adaptive sync" technologies. Without getting too deep in the weeds, all iii are designed to forestall screen fierce (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 activeness.
They achieve this past aligning the refresh rate of the monitor on the wing with the frame-rate output of the video card, merely cartoon a frame when a full 1 is delivered, rather than at a fixed rate. Though adaptive sync is not essential for gamers who mostly play single-role player, slow-paced titles, it'southward groovy for anyone taking his or her skills into the online multiplayer arena in serious, competitive fashion.
Note that you demand a uniform graphics bill of fare to work with Thou-Sync or FreeSync. G-Sync requires a compatible Nvidia GeForce carte du jour (all belatedly-model cards back up it), and FreeSync needs an AMD Radeon RX one. Note that a relatively new subset of monitors, dubbed G-Sync Compatible, have been designated by Nvidia to also piece of work with the adaptive-sync tech on its cards despite not having the specific and exclusive M-Sync-enabling circuitry of earlier G-Sync monitors.

Creating in 4K: Pro Graphics Panels
Seeing every bit 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 4K monitors come in.
Professionals were amidst the first folks to get monitors that featured truthful 4K-pixel-count panels, and these buyers continue to drive the market forrard with 5K, 6K, and fifty-fifty 8K monitors peeking out just over the horizon.
A 4K monitor is a nice addition to any amateur or professional creator's armory, though it should exist noted that in terms of color reproduction or accuracy, at that place'due south nothing inherently better almost 4K monitors than 1440p or 1080p displays. Instead, the chief benefit is for those who work in high detail, notably in photography, 3D visual arts, or cinematography. In those areas, having more pixels to work with gives you a greater level of accuracy, whether you're drawing angel wings on an image of a model, creating vector art, mastering a motion-picture show, or doing anything that requires zooming in and retaining every bit much visual fidelity every bit possible.
Some other benefit is simply sheer workspace. Fifty-fifty if your ultimate output isn't in 4K, working on a 4K panel can let you look at your content at full target resolution while leaving screen infinite for palettes, command menus, timelines, and other creation tools. Of class, yous could relegate that stuff to a 2d monitor if yous need the infinite, just a 4K panel tin enable unmarried-display workflows that were not possible or but were more bad-mannered before.
Colour-gamut coverage is a key specification for many folks in this infinite. A number of 4K professional monitors accomplish industry specifications of covering 100% of sRGB, equally well as strong results with the Adobe RGB and DCI-P3 color gamuts. Expert examples of these panels that we take 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 Office: Panels With Productivity Features
Keeping busy on a 4K monitor isn't much different from doing general work on a monitor of a lesser resolution, but for one key difference: effective screen infinite. Because a 4K monitor has four times the available pixels than a 1080p monitor, this gives you, in theory, four times equally much elbow room to mount windows side by side.
The reason we say "in theory"? The idea is sound, but in practice it's nigh impossible to brand out the same 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 short for "dots per inch"). For example, when you lot switch your resolution from 1080p to 4K in Windows 10, by default Windows x volition auto-scale your content to 150% of its standard DPI.
This increases the size of all rendered elements on the screen by that percentage. At 150% scaling, it's more than likely that you'd be able to fit two or three standard browser windows next and still clearly read their text. With 4 windows, one per corner of the screen? Not and then likely.
To aid simplify your workflow fifty-fifty more than, some 4K monitors, such as the business-centric Dell U3219Q pictured above, come up with congenital-in features like an automatic window-sizing tool. (Information technology sections off parts of your screen that programs in Windows will resize to on their ain.) Similarly, these monitors can have video signals from multiple sources and brandish them adjacent ("moving picture by picture") or inlaid in a larger window ("picture in picture"). This can be useful, say, if you have a PC that y'all're developing on, but you demand to exam your changes in your program on a separately continued Mac at the same time.
Connections, Adjustments, and HDR
Some specs are not every bit front-and-centre equally the display type or the refresh charge per unit, only they will bear on how you lot work with your 4K display mean solar day to day.
The stand's allowable adjustability might seem trivial, only it can touch your comfort, depending on where and how you use your panel. A range of tilt is pretty standard (normally, the monitor maker will express it in degrees forward and dorsum), but you'll want to look for the ability to hinge the panel left and right on its stand up or rotate information technology between mural and portrait modes. (The latter is uncommon and mostly for serious photo editors.)
Connectivity is another thing to bank check, though for most folks, it comes downwardly to an HDMI or DisplayPort input, and virtually 4K panels will accept both, sometimes several. Scout for a match with your video source. A few panels support input via Thunderbolt 3, suited for input from certain laptops, notably late-model MacBook Pros. A few nongaming models in contempo months take ditched HDMI and DisplayPort altogether in favor of Thunderbolt iii exclusively.
One note: To get a 4K display running above the 60Hz refresh-charge per unit threshold (mostly of involvement to gamers or game developers), you need a video bill of fare capable of outputting its signal over a DisplayPort 1.4b cablevision, and with some 4K 144Hz monitors (such as the Acer Nitro XV273K), you lot'll demand two such connections plugged in concurrently.
Finally, there's the issue of HDR. High-dynamic range is a colour specification common on modern 4K TVs, but it has made inroads into monitors over the past few years. (Run across our HDR primer for much more than groundwork on information technology.) Of course, y'all'll need media recorded in HDR, or games that back up the HDR spec, in order to enjoy it.
That said, if you have a monitor that also plugs into an Xbox One X, for example, that console will display all kinds of HDR content as a plug-and-play experience without issue.
And so, Which 4K Monitor Should I Purchase?
Upgrading to a 4K monitor, as you lot tin can see, entails a lot more than just a unproblematic resolution uptick. Only now, armed with our overview, it's time to shop. We've tested a host of 4K monitors out at that place and pulled out a choice of the very best that represents all the main usage classes: business organization-facing monitors, gaming ones, and creative/professional panels. Let's dig in...
