Actually being able to make use of the best 4K gaming monitors is becoming easier and easier. While Ultra HD resolution still demands a lot from your graphics card, gen-on-gen GPU performance improvements (coupled with upscaling tech like DLSS) are enabling smoother PC game performance than ever. As such, upgrading to a 4K display for high-end play is making more and more sense.
Especially so, now that 4K monitors now more commonly feature the same high refresh rates, low response times, and adaptive syncing features as rest of the best gaming monitors. Again, you’ll need a pretty brawny graphics card to consistently stay above 60fps at 4K – I’d recommend at least the DLSS 3-supporting GeForce RTX 4070 Ti – though if you’re happy with more of a 45-60fps range, there are 60Hz models you can get on a relatively tight budget.
Below are all the best 4K gaming monitors we’ve tested, using a combination of games-playing experience and more objective colour, brightness and contrast recordings taken with a colourimeter. See? We can be scientific. Point is, if you want a 4K monitor that won’t muck up your games with crap colour reproduction or distracting ghosting effects, these are the ones to buy.

BenQ EL2870UThe best cheap 4K gaming monitor
4K gaming monitors often cost an arm and a leg, but the BenQ EL2870U shows you needn't break the bank to get a great 4K display. It doesn't have as many bells and whistles as some of the other screens on this list, such as a high refresh rate or a height-adjustable stand, but its 28in TN panel is still capable of displaying rich, vivid colours to make your games look great.
It's not the brightest 4K gaming monitor in the world, topping out at around 280cd/m2, so you'll probably have to have it on max if you work or play games in a particularly bright room. Under normal lighting conditions, though, this should still be plenty for everyday use, and BenQ's clever ambient light sensor can automatically adjust the monitor's brightness to make sure it's always appropriate for your surroundings and help reduce eye strain.
The BenQ EL2870U also comes with AMD FreeSync support for smooth tear-free gaming, and while it's not an officially certified G-Sync Compatible monitor, Nvidia graphics card owners should still be able to make use of its variable refresh rate technology by enabling it in their Nvidia Control Panel. All in all, it's a great screen for the money, and you'll be hard-pushed to find a better-looking 4K display for less.

Dell UltraSharp U2720QThe best no-frills 4K gaming monitor
The Dell UltraSharp U2720Q made several key upgrades on the U2718Q that Katharine still uses as an everyday monitor, including proper VESA DisplayHDR 400 support for entry-level HDR, and a USB-C port with power delivery that you can use to charge USB-C laptops and smartphones.
It doesn't have a super high refresh rate like some of the other 4K monitors on this list, but if you're after a 'normal' looking 4K screen that's just as good for playing games on as it for home working, then this is the monitor to buy. The U2720Q shares exactly the same design as the U2718Q, including its super slim bezels, and its IPS panel is just excellent, producing rich, accurate colours along with great contrast and low black levels. Plus, the U2720Q's HDR support means you can really let those colours sing in compatible games, too.
Best of all, it has a height-adjustable stand, giving it an important leg-up over the fixed BenQ above. It's a truly great 4K display, and one that gets our seal of approval. Especially Katharine's.
Corsair Xeneon 32UHD144The best 144Hz 4K gaming monitor
Here’s a list of everything I don’t like about the Corsair Xeneon 32UHD144: the stand is kind of big. That’s it. This is a big, bright, intensely vivid 4K/144Hz gaming monitor that’s a visible step up from mid-range alternatives (like the AOC U28G2XU/BK) while keeping the price… well, not low, but fair for the quality you’re getting.
There are a few colour profiles in the OSD (itself simple and easily usable with the rear-mounted joystick), but even the Standard mode is gorgeous. This covers 99.8% of the sRGB and 99.6% of the Adobe RGB gamuts, with a comfortable 1019:1 contrast ratio, so games always look as bold as they do sharp. There’s AMD FreeSync Premium support too, which morphs into effective Nvidia G-Sync compatibility when connected to a GeForce GPU.
HDR performance isn’t outright dazzling, but with a peak of 686cd/m2 in Final Fantasy XV, it’s brighter than most. And that desk hog of a stand is heavy-duty in a good way too, while offering ample adjustment for the main screen.
AOC U28G2XU/BKThe second best 4K 144Hz gaming monitor
The AOC U28G2XU/BK remains the best 4K 144Hz monitor at its price, even if the more premium Corsair Xeneon 32UHD144 has greater allure on the whole. It also uses a colourful IPS panel, though is more on-target with its colour accuracy, hitting a very respectable 2.3 average delta-E (1 is ideal, and it’s common for gaming monitors to exceed 4).
That makes the U28G2XU/BK a good choice for anyone who prefers a more natural colour profile to eye-punching saturation, though it’s far from bland-looking either: I measured its out-of-the-box settings reaching 98.5% sRGB colour gamut coverage and a 1012:1 contrast ratio. It’s smooth, too, with no real ghosting problems and support for both G-Sync and Freesync Premium Pro.
Its desk-friendly 28in screen size and highly adjustable stand round out a commendably constructed monitor. The only thing you’d have to give up is true HDR: the U28G2XU/BK has VESA DisplayHDR 400 certification, but I could only record it reaching 356cd/m2 in games.
Asus ROG Swift PG32UQXThe best 4K HDR gaming monitor
Oof. That much for a single monitor? Indeed, the Asus ROG Swift PG32UQX is the opposite of accessible; if anything, it’s a statement of how far you’re willing to go to get hold of the latest tech.
That said, it’s also a very, very, very good 4K gaming monitor. Response times could be higher but everything I played looked glorious at 100fps+ 4K, and colour coverage and accuracy are truly top-tier. The ROG Swift PG32UQX is build to last too, with a reliable stable, adjustable and sharp-looking metallic stand.
What you’d really be paying for, though, is Mini LED backlighting. This is a generational upgrade on the crude edge backlighting you get on most IPS monitors, cramming thousands of tiny LEDs across the entire panel for a superior combination of high brightness, high contrast and bleed-free backlighting uniformity. Its brightness benefits are of particular use to games that support HDR, as the ROG Swift PG32UQX can tip over the 1000cd/m2 mark on bright spots without unintentionally lighting up any contrasting dark areas.

Philips Evnia 42M2N8900The best TV-sized 4K gaming monitor
Not only is the Philips Evnia 42M2N8900 a titan of a gaming monitor, it’s also an impressive early showing for OLED panel tech in a 4K gaming monitor. Perfect infinity: 1 contrast, 100% SRGB gamut coverage, and absolutely non-existent ghosting are OLED’s three big benefits here, giving games a sumptuous vibrancy.
That is, it should be said, in spite of its low brightness, so it’s not the best for HDR support. And OLED is higher-maintenance than IPS or VA, with the Evnia 42M2N8900 regularly wanting a screen refresh to prevent burn-in. To be clear, though, I don’t think it’s at serious risk of this: I could play shooters for hours without HUD elements searing into the screen in the process. Just don’t leave it on for days at a time and you’ll be fine.
Besides looking excellent, the Evnia 42M2N8900 also has the advantage of an adjustable stand: megasized monitors often go for a fixed set of feet instead, making it harder to set them up at a comfortable angle. And that’s just one of several hardware extras, from the reactive Ambiglow ambient lighting to its HDMI 2.1 connectivity. The latter will be useful if you want your TV-sized gaming monitor to indeed act as a TV, and connect to a 4K-capable games console as well as your PC.

Frequently asked questions
Why are lots of 4K gaming monitors only 60Hz?
It all comes down to how much bandwidth is available in your monitor's display inputs. It takes a lot of bandwidth to power a 4K display, especially once you throw HDR into the mix, and opting for more pixels often comes at the cost of a high refresh rate. For example, while HDMI 2.0 can quite happily support a refresh rate of 144Hz at 2560x1440, it's currently limited to just 60Hz when you move up to 3840x2160. DisplayPort 1.4, on the other hand, offers more bandwidth than HDMI 2.0, allowing up to a maximum of 120Hz at 3840x2160 with HDR - although some monitors will let you overclock them to 144Hz in their onboard menu settings. As a result, if you see a 4K monitor with a high refresh rate at the moment, there's a decent chance it can only manage that rate over DisplayPort. If you connect it to your PC over HDMI 2.0, you'll be stuck with 60Hz.
The good news is that HDMI 2.1 monitors, which allow for 120Hz refresh rates at 4K (and 144Hz with compression), have arrived. The world's first HDMI 2.1 gaming monitor, the Asus ROG Strix XG43UQ, launched in May 2021, with several more following it. DisplayPort 2.0 is also on the way, and should allow for 4K at 240Hz without compression, though we haven't seen any compatible gaming monitors announced yet (the Samsung Neo G8 uses compression to hit 240Hz).
Can a 4K monitor run at 1440p?
Yes. All you need to do is go to Windows' Display Settings, and set your Display Resolution to 2560x1440, as shown below.
Are 4K gaming monitors worth it?
With their high pixel count and sharp, crisp pixel densities, 4K monitors can be brilliant tools for everyday desktop work. They provide plenty of space for looking at several desktop applications at once, and they also make it much easier to see and juggle multiple windows in creative applications such as Adobe Photoshop and Premiere Pro. If you regularly use these kinds of apps in your everyday work life, 4K monitors are almost definitely going to be worth the extra investment over lower resolution displays.
That said, if your main reason for buying a 4K monitor is to simply play games at a 4K resolution, then you'll need to make sure you've got a powerful enough PC to really make the most of it. This can end up being quite the costly endeavour, as you'll need one of today's best graphics cards inside your PC in order to play them at a decent frame rate. I wouldn't try go any lower than the Nvidia GeForce RTX 3070 or AMD Radeon RX 6800, although if you want to play at higher quality settings, then you really want either an RTX 3080 or RX 6800 XT. Best of all would be an Nvidia RTX 40 series GPU, like the RTX 4070 Ti. These support DLSS 3, an upgraded version of the DLSS upscaler that can further boost framerates by adding in entirely AI-generated frames between the ones that your card is rendering normally. This makes for smoother motion, without putting more strain on the GPU's rendering capabilities.
Ironically, the cheapest way of getting a full-blown 4K gaming system in your house is probably buying an Xbox Series X or PlayStation 5. As we found out when we tried to build an equivalent Xbox Series X PC, we would have had to spend almost £1500 to get the same kind of 4K gaming chops as the Series X, which is over a grand more than what the console costs. In this sense, the question of whether 4K gaming monitors are 'worth it' depends very much on how badly you want to play games at this resolution, and how much you're willing to spend in order to get there.
Of course, there's nothing wrong with buying a 4K monitor and then using it to play games at 1440p. If anything, it gives you even more flexibility than lower resolution screens, especially if you're in the process of trying to upgrade your PC at the moment, or you're waiting for graphics card prices to come back down to normal again. And, even though 1440p is arguably more of a sweet spot for games in terms of balancing sharpness and performance, 4K monitors are much better for everyday desktop tasks, you'll likely thank yourself later for getting a screen with more pixel real estate.
