Best 4K Gaming Monitors for PC 2021: 144Hz, Curved and More

Best 4K Gaming Monitors

With great pixels comes great image quality. So it's not surprising when PC gamers drool over monitors with 4K resolution. A panel packing 8.3 million pixels (3840 x 2160) makes your favorite games look incredibly sharp and realistic. In addition to being the highest resolution you can get in a good gaming monitor these days, going 4K also offers the ability to expand past 20-inch screens. With that loaded pixel army, you can stretch your screen size well past 30 inches without having pixels so big that you can see them. And the new graphics cards from Nvidia's RTX 30-series and AMD's Radeon RX 6000-series make the move to 4K even more tempting.  

But that image quality comes at a steep price. Anyone who's shopped for a 4K monitor before knows they're not cheap. Yes, 4K is about high-res gaming, but you're still going to want solid gaming specs, like a 60Hz-plus refresh rate, low response time and your choice of Adaptive-Sync (Nvidia G-Sync or AMD FreeSync, depending on your system's graphics card). And you can't forget the cost of the decently beefy graphics card you'll require to game properly in 4K. If you're not ready for 4K yet, see our Best Gaming Monitors page for lower-res recommendations. 

For those ready for high-res gaming (lucky you), below are the best 4K gaming monitors of 2021, based on our own benchmarks.

Quick Shopping Tips

When seeking the best 4K gaming monitor for you, consider the following:

  • G-Sync or FreeSync? A monitor’s G-Sync feature will only work with PCs using an Nvidia graphics card, and FreeSync will only run with PCs carrying an AMD card. You can technically run G-Sync on a monitor that's only FreeSync-certified, but performance may vary. We've seen negligible differences in mainstream gaming capabilities for fighting screen tearing between the two. Our Nvidia G-Sync vs. AMD FreeSync article offers an in-depth performance comparison. 
  • 4K and HDR go hand-in-hand. 4K displays often support HDR content for extra bright and colorful images. But for Adaptive-Sync optimized for HDR media, you'll want a G-Sync Ultimate or FreeSync Premium Pro (formerly FreeSync 2 HDR) monitor. For a noticeable upgrade from an SDR monitor, opt for at least 600 nits brightness. You can learn more from our glossary page on HDR and our buying guide for picking the best HDR monitor.

LG's 27GN950-B is colorful, accurate and the best 4K gaming monitor for most.  (Image credit: LG)

1. LG 27GN950-B

Best 4K Gaming Monitor

Specifications
Screen Size & Aspect Ratio: 27 inches,16:9
Panel Type: IPS
Refresh Rate: 144Hz
Response Time (GTG): 1ms
Adaptive-Sync: G-Sync Compatible, FreeSync
Reasons to buy
+Local dimming produces VA-like contrast+Wide and accurate color gamut+Fast and responsive
Reasons to avoid
-Oversaturated sRGB mode

With speed, accurate color and high contrast, the LG 27GN950-B is the best 4K gaming monitor and our top recommendation. There’s tough competition on this page, but the 27GN950-B stands out with some of the best input lag scores we’ve seen of a 144Hz monitor (tying with the Asus ROG Strix XG27UQ below) while also keeping up with its rivals in our response time testing.

Image quality is also a sight to hold. With an edge array backlight with a local dimming feature, the 27GN950-B doesn’t quite hit FALD-level HDR but still brought stellar performance with 8,475.3:1 contrast ratio. LG also implemented its Nano IPS panel, the answer to Samsung’s Quantum Dot tech, to achieve massive color coverage (94.5% of DCI-P3 and 133.9% of sRGB after our recommended calibration) that really made games pop.

2. Asus ROG Strix XG27UQ

Best 144Hz 4K Gaming Monitor

Specifications
Screen Size & Aspect Ratio: 27 inches, 16:9
Panel Type: IPS
Refresh Rate: 144Hz
Response Time (GTG): 1ms
Adaptive-Sync: FreeSync
Reasons to buy
+Quickest 4K monitor we’ve tested+Richly saturated color
Reasons to avoid
-Expensive compared to other 144Hz 27-inchers

The Asus ROG Strix XG27UQ is the best 144Hz 4K gaming monitor and may be cheaper than you expect, as we've seen it listed for $800. The XG27UQ doesn’t have a premium FALD backlight for beautiful HDR; however, HDR performance is still impressive, thanks to an effective edge-array backlight and the screen's Dynamic Dimming feature.

The ROG Strix XG27UQ stacked up well in our testing when it came to both response time and input lag. In the input lag test, it outperformed other 144Hz monitors, including the Acer Predator X27 and Asus ROG Swift PG27UQ, which went for about $2,000 each. And while the XG27UQ is listed as a FreeSync monitor, we were able to run G-Sync on it successfully.

3. Acer Predator XB273K

Best 144Hz 4K Gaming Monitor Value

Specifications
Screen Size & Aspect Ratio: 27 inches, 16:9
Panel Type: IPS
Refresh Rate: 144Hz
Response Time (GTG): 4ms
Adaptive-Sync: G-Sync
Reasons to buy
+Superb gaming performance+Out-of-box color accuracy+HDR+DCI-P3 color
Reasons to avoid
-Expensive

A little more affordable than the other 144Hz options on this page, the Acer Predator XB273K is the best 4K gaming monitor at that ideal refresh rate for value-seekers.  During fast-paced games with settings maxed, there was no blur. G-Sync worked successfully--with both standard and HDR content-- to fight screen tearing when paired with an Nvidia graphics card. The monitor kept up well with other 144Hz displays during our testing and even beat the Asus ROG Swift PG27UQ and Acer Predator X27, which are about $2,000 monitors, when it came to input lag. 

In terms of image quality, the Predator XB273K delivers with pro-level color accuracy and contrast that reached over 4,000:1, according to our testing, and over 2,000:1 after our calibration. HDR doesn't look as good as it does on monitors with FALD backlights, but we consider the Predator XB273K the next best thing.

4. Asus ROG Swift PG32UQX

Best 4K Gaming Monitor for HDR

Specifications
Screen Size & Aspect Ratio: 32 inches / 16:9
Panel Type: IPS
Refresh Rate: 144 Hz
Response Time (GTG): 4ms
Adaptive-Sync: G-Sync Ultimate
Reasons to buy
+Incredible contrast+OLED info screen
Reasons to avoid
-No Dolby Vision-No motion blur reduction

If you want the best 4K gaming monitor for HDR movies and games, the Asus ROG Swift PG32UQX is an expensive, but impressive, buy. This is the first gaming-focused monitor with Mini LED. Thanks to that advanced backlight, we recorded an amazing HDR contrast ratio of 180,820.8:1. And while an OLED screen like the Alienware on this page can offer deeper, purer blacks, the PG32UQX can get much brighter. It hit 1,627 nits with HDR during testing. 

We loved watching HDR films on the screen, but there’s no Dolby Vision support. This won’t affect many games, but 4K Blu-ray discs and content from Netflix and the like often use Dolby Vision. On the other hand, you do get support for 24p film candences. 

And as a gaming monitor the PG32UQX is no slouch either. It performed admirably against other 144 Hz screens in our response time and input lag tests, even besting some, including the HP Omen on this page, in the latter. And the nifty OLED screen on the bottom uniquely relays helpful information, like refresh rate adn CPU and GPU temperatures.

5. Asus TUF Gaming VG289Q

Best Budget 4K Gaming Monitor

Specifications
Screen Size & Aspect Ratio: 28 inches, 16:9
Panel Type: IPS
Refresh Rate: 60 Hz
Response Time (GTG): 5ms
Adaptive-Sync: FreeSync
Reasons to buy
+Good value+Accurate color+Good build quality
Reasons to avoid
-Average contrast-HDR looks only slightly better than SDR

You don’t often see the word budget associated with a 4K monitor, but the Asus TUF Gaming VG289Q isn’t just affordable, it’s a great gaming monitor too. Despite being available for $349 as of writing, it offers a great amount of performance, making it a fantastic value for gamers looking to get to 4K without breaking the bank. We've even seen 4K monitors priced at $400 offer lesser gaming performance. 

There was no ghosting when we gamed on the VG289Q, and overdrive successfully helped eliminate motion blur. SDR titles looked extra colorful, but there was hardly any improvement when moving over to HDR games. 

With the VG289Q priced so low, it’s not surprising that its refresh rate is limited to just 60 Hz (FreeSync works down to 48 Hz). Hardcore gamers will want more Hz, but casual players can make due with fast-paced scenes showing sufficient detail and great pixel density.

6. Acer ConceptD CP7271K

Best 4K Gaming Monitor for Professionals

Specifications
Screen Size & Aspect Ratio: 27 inches, 16:9
Panel Type: IPS
Refresh Rate: 144Hz with overclock
Response Time (GTG): 4ms
Adaptive-Sync: G-Sync Ultimate
Reasons to buy
+Reference-level color accuracy+Huge color gamut+Tremendous contrast+HDR with FALD backlight at 1,000 nits brightness and G-Sync Ultimate
Reasons to avoid
-No portrait mode-No selectable color gamuts

The lines separating the monitor needs of gamers and professionals keeps blurring. Besides that, there’s nothing wrong with a photo editor wanting to game during their free time, right? The Acer ConceptD CP271K is the best 4K gaming monitor for professionals because it boasts impressive gaming specs coupled with accurate color space coverage. 

Creative professionals can get work done with the monitor’s 110% coverage of the DCI-P3 color space, although the very meticulous will find that to be slightly too colorful. You can, however, reduce color with a software look-up table. You also get great HDR output with a FALD backlight that reaches 1,000 nits. 

At the same time, the ConceptD CP271K offers gamers accurate sRGB coverage (96.3%), as well as powerful performance that kept up with 144 Hz gaming monitors in our response time and input lag benchmarking.

7. Gigabyte Aorus FV43U

Best Big-Screen 4K Gaming Monitor

Specifications
Screen Size & Aspect Ratio: 43 inches, 16:9
Panel Type: VA
Refresh Rate: 144Hz
Response Time (GTG): 1ms
Adaptive-Sync: FreeSync
Reasons to buy
+Huge color gamut+Accurate out of the box
Reasons to avoid
-No 24p support-No Dolby Vision

If you’re looking for a big 4K experience, the Aorus FV43U offers excellent image quality and gaming performance at a much cheaper price than screens with slightly lesser image quality. We've seen it for as cheap as $1,000, giving the $1,500 Asus ROG PG43UQ on this page a run for its money. The Aorus bested the Asus in our contrast (SDR and HDR) and max brightness tests, as well as in color coverage. The Asus did beat the Aorus in our response time test by 1ms and in input lag by 7ms, but unless you’re an extremely competitive gamer, it’s probably worth the price savings and slight image quality advantages. 

The Aorus FV43U also offers USB-C connectivity, allowing you to hit 144Hz, two 12W speakers that sound better than most and a remote. HDR performance is also top-of-the-line, with our benchmarks recording 38,888.4:1 contrast and HDR games showing amazing depth and popping textures. A lack of 24p and Dolby Vision support hurt the FV43U’s chances as a full TV replacement, but there isn’t much else missing in a premium gaming monitor here.

8. Asus ROG Swift PG43UQ

Best Big-Screen 4K Gaming Monitor Splurge

Specifications
Screen Size & Aspect Ratio: 43 inches, 16:9
Panel Type: VA
Refresh Rate: 144Hz
Response Time (GTG): 1ms
Adaptive-Sync: FreeSync, G-Sync Compatible
Reasons to buy
+99% DCI-P3 color coverage+Killer HDR+Handy remote
Reasons to avoid
-Hard to find-Too bright for darkly lit rooms-No 24p film mode for Blu-ray movies

We loved the Asus ROG Swift PG43UQ when we first saw it in June, but it’s been hard to find online ever since. We reviewed it at $1,500 but have seen it sell for more. If you can find this massive screen at the right price, you won’t be disappointed. 

At 43 inches, the ROG Swift PG43UQ is juggernaut that makes for a great TV replacement -- it even has a remote. From a 4-foot distance, it lends to a highly immersive experience that rivals a curved ultra-wide. And with DisplayHDR 1000 certification, HDR movies pack a punch. Games looked incredibly realistic and warm in HDR and also natural and vibrant in SDR. 

Most importantly, the PG43UQ is specced for high-performance gaming. Response time competed well against other 144 Hz screens in our benchmarks, and input lag was better than the equally priced Acer Predator CG437K. If you can't find the Asus in stock though, the Acer's a fine substitution with a drop less performance for around $1,455

With a 1500R VA panel, here's our favorite curved 4K monitor for gaming.  (Image credit: Samsung)

9. Samsung UR59C

Best Curved 4K Gaming Monitor

Specifications
Screen Size & Aspect Ratio: 32 inches, 16:9
Panel Type: VA
Refresh Rate: 60Hz
Response Time (GTG): 4ms
Adaptive-Sync: None
Reasons to buy
+Quality build+Effective curvature
Reasons to avoid
-No G-Sync or FreeSync-Needs calibration

The Samsung UR59C isn’t a gaming monitor exactly, but you’d be surprised at the speed it offers compared to other curved, 4K so-called gaming monitors. For example, the MSI Optix MAG321CURV, a 32-inch curved 4K gaming monitor, showed a 22ms response time in our testing and 71ms input lag, while the UR59C posted the same response time but a shorter 63ms input lag. No, this is not a high-end gaming monitor. But 4K at 60 frames per second (fps) is a lot more attainable than 144 fps, which may make the lack of Adaptive-Sync acceptable, depending on your GPU’s capability. A low price makes this one of the best budget 4K monitors overall too. 

We haven’t seen many curved 4K gaming monitors but found the UR59C’s 15000mm curve noticeable and effective in upping productivity with multiple windows open. The curve didn’t feel as extreme as it would on an ultrawide, but that also meant no distortion. 

Games looked tear free and without obvious lag when we paired it with a GTX 1080 Ti, while the VA panel’s high contrast 2,648.4:1 out of the box, (according to our testing) made cut scenes feel like a movie and graphics, like trees and dirt, more realistic.

10. Aorus FO48U

Best 120Hz 4K Gaming Monitor

Specifications
Screen Size & Aspect Ratio: 47.5 inches / 16:9
Panel Type: OLED
Refresh Rate: 120Hz
Response Time (GTG): 1ms
Adaptive-Sync: FreeSync Premium
Reasons to buy
+HDMI 2.1 and DisplayPort 1.4 with DSC+Stunning image with deep contrast and saturated color
Reasons to avoid
-Not as bright as a premium LCD-No Dolby Vision

It’s very rare to find an OLED-based gaming monitor. The Aorus FO48U brings the rich contrast and massive color gamut that OLED allows, while being brighter than the Alienware AW5520QF 55-Inch OLED, the only other gaming OLED monitor currently available. With a 120 Hz refresh rate and HDMI 2.1, the FO48U is also ready to connect to the PS5 and Xbox Series X and S and run their max speeds.

With a 120 Hz refresh and 1ms GTG response time, the FO48U kept up with 120 and 144 Hz rivals during our response time test but was 4ms behind the Alienware OLED when it came to total input lag. But for a much brighter screen (even if it doesn’t quite match a nice LCD’s max nits) and greater color gamut (107.7% DCI-P3), that’s a small price to pay. 

Unfortunately, a lack of Dolby Vision and support for the 50p and 24p TV formats make it harder for the FO48U to completely replace your TV, but a pair of 15w speakers, plus one 20w one take care of audio.

11. HP Omen X 65 Emperium

Best 4K Monitor for Couch Gaming

Specifications
Screen Size & Aspect Ratio: 64.5 inches, 16:9
Panel Type: VA
Refresh Rate: 144Hz
Response Time (GTG): 4ms
Adaptive-Sync: G-Sync
Reasons to buy
+Pro-level color accuracy+Excellent SDR and HDR contrast+Built-in soundbar delivers excellent audio quality+Sturdy build
Reasons to avoid
-Very expensive

If you’re a couch gamer, you need a monitor that’s fit for replacing your TV. With a 64.5-inch display, the HP Omen X 65 Emerpium is amply equipped to do just that. This juggernaut of a gaming monitor offers larger-than-life gaming. In testing, performance matched its high price tag with zero gaming hiccups and high frame rates at high settings. 

HP also included some unique bonuses that make this monitor even more fitting for the living room. An included soundbar featuring four 4-inch woofers, two 1-inch tweeters and two passive radiators add to the feeling of immersion. The monitor also comes with Nvidia Shield Android-based streaming interface, which means gaming, TV and movie-streaming options are built right into your gaming display. A remote completes the living room package. 

And if you’re into HDR, the Omen X 65 Emperium would make a great HDR display with high contrast, according to our tests, and certification to play HDR at a minimum brightness of 1,000 nits.

    Did Prices just explode all of a sudden?

    Some of the best are back up to $2000 MSRP and not far below at retail. I thought we were seeing lower $1000's a week or so back.
    Or maybe I just haven't been noticing, but I have been web "window shopping" these last weeks or so.

    anything past 500$ is kind of useless, unless you also using it to "work" on it.
    i can buy a 49" 4K tv with 120hz and local dimming for sub 1000 (even brands like sony),
    and use a lower res like 1080 to play (tvs upscale 1080p content properly),
    which would also reduce (4K related) input lag a bit and will not require a 1070.

    What about the Samsung CRG90 ? 49", super ultra wide 5120 x 1440 , HDR 1000, 120hz (overclockable to 144), native freesync. I ordered one, it's coming tomorrow to replace my 32" QHD 60Hz NoHDR really looking forward!!! only 1,200 Eur!!!

    Anything less than 32 inch is to small for 4K. Things will be small and far away. 2k works though at around 28 inch.

    Typically stores will jack up the prices before Black Friday and then they can list a sale price and post a bigger difference - "Now $800 off the previous price"

    I'm curious with TomsHardware is going to start reviewing FreeSync TVs for gaming. You're bringing up the future of 4k OLED monitors coming, and Alienware's 55" being around $4000. Samsung's 8000 series and up (55" and up) have 4k, HDR and FreeSync. And LG's new firmware for most of their OLED TVs also enable FreeSync. All are much cheaper than Alienware's, even at bigger sizes.
