Gaming has evolved in recent years, with new 4k screens delivering a more detailed gaming experience. Console and PC gamers alike have embraced this new format, with upgraded consoles released mid-cycle that can take advantage of the greater levels of detail provided by these new screens. This doesn't come without trade-offs, though, as most 4k screens have slower refresh rate and, by extension, slower response times than their lower-resolution counterparts.
We've reviewed over 110 monitors, and below are our picks for the best 4k gaming monitors to buy. See also our recommendations for the best monitors for Xbox One, the best monitors for PS4, and the best monitors for PC gaming.
The best 4k gaming monitor we've tested so far is the LG 27UK650-W. This is a simple 27 inch monitor that's meant for general office use, but it performs well enough for most casual gamers, especially if you're into atmospheric games or RPGs. The 4k resolution brings out every little detail to provide an immersive gaming experience, and it has a fast response time that results in minimal motion blur. Its input lag is exceptionally low, and it even supports FreeSync variable refresh rate to minimize screen tearing when gaming. Unfortunately, the refresh rate is limited to 60Hz; however, it shouldn't be an issue for most people, as it's still challenging to achieve a high frame rate at a 4k resolution with current hardware.
The monitor's build quality is decent, but the ergonomics are sub-par, as it lacks swivel adjustment and the tilt range is quite narrow. Thankfully, it has great viewing angles, so the image doesn't degrade much if you're viewing from the side. It has an impressive peak brightness that makes it suitable for most lighting conditions, but it isn't the best option for dark rooms, as its low contrast ratio and mediocre black uniformity make blacks look grayish. And although there's HDR support, this monitor can't display a wide color gamut and doesn't get bright enough to make highlights stand out in HDR content.
There's not much in terms of extra features; you only get a Super Resolution feature to upscale lower resolution content, and a black stabilizer feature to make objects more visible in dark scenes. It's worth noting that the VRR support also extends to G-SYNC, so it should work with recent 10- or 20- series NVIDIA graphics cards. Overall, although it isn't the most feature-rich monitor for gaming, it's a great option if the 4k resolution is important to you.
If you find a 27 inch screen too small, then check out the LG 32UD99-W. It looks almost identical to the LG 27UK650-W, and it performs very similarly as well. It has a slightly higher contrast ratio, which results in deeper blacks, and it can get a bit brighter, especially in HDR. The main downside is that this monitor's response time is a little slower, so there's more motion blur in fast-moving scenes. Also, it has worse reflection handling, making it less suitable for bright rooms. On the upside, it can display a wide color gamut to deliver a better HDR experience, and it comes with a USB-C port that supports DisplayPort Alt mode. This means that you can display an image from a compatible device like a MacBook Pro, and charge the device at the same time with a single cable.
Overall, the 27UK650-W is a better choice for gaming due to its faster response time; however, if you need the extra screen real estate, then go with the 32UD99-W.
If you want a monitor with better dark room performance, consider the 32 inch BenQ EW3270U. Since it's a bigger monitor, the pixel density isn't as high as the LG 27UK650-W, but it still produces a good quality image and it's able to display deep blacks thanks to its VA panel. It also has a good response time at 60Hz, although there's a bit more motion blur than the LG. This monitor supports FreeSync and it's G-SYNC compatible with newer NVIDIA graphics cards, and it has a low input lag. Unfortunately, it doesn't have wide viewing angles and it doesn't get very bright, but luckily it has good out-of-the-box color accuracy and it has some nice extra features like built-in speakers.
If you want the best 4k gaming monitor we've tested so far, you can't go wrong with the LG, but if you want a monitor with better dark room performance, look into the BenQ.
The best 4k G-SYNC gaming monitor we've tested so far is the Acer Predator X27. Although pricey, this monitor is a great choice for anyone who wants a high refresh rate and native G-SYNC support without compromising on resolution. It's well-built and the stand provides sturdy support, but its ergonomics are rather mediocre, as it can't rotate into portrait mode.
As expected of most gaming monitors, it has a fast response time and low input lag, although latency does increase if you play at 60Hz. This monitor uses an IPS panel that provides good viewing angles, so images remain accurate even if you're not seated directly in front of the screen. There are built-in speakers if you need them, and the backlight is flicker-free, which can help reduce eye strain for those long gaming sessions. There are also four USB 3.0 ports to charge your mobile devices, with two of them conveniently placed on the side of the monitor.
Sadly, it has a sub-par contrast ratio and poor black uniformity, making it less ideal for dark rooms, which is typical of most IPS panels. On the upside, it has an impressive wide color gamut and excellent peak brightness to provide a great HDR experience. Overall, this is a no-compromise monitor that should satisfy even the most demanding gamers.
If the Acer Predator X27's price is out of reach, consider the Acer Predator XB273K. This monitor also uses an IPS panel, but it has a slightly higher native contrast ratio, as well as a more accurate color reproduction right out of the box. Sadly, black uniformity is just as bad, with severe clouding throughout the screen, and it can't get bright enough to really bring out highlights in HDR content. Also, it lacks a local dimming feature and its reflection handling is just okay, so it's best to avoid placing the monitor opposite a source of bright light.
If you can afford it, the X27 is still a better choice, but if you're okay with a few compromises, the XB273K is a good alternative.
The best budget 4k gaming monitor we've tested so far is the LG 27UD58-B. This monitor follows a very familiar LG design, except that it has much thicker bezels, which is less ideal for multi-monitor setups. Build quality is decent, but unfortunately, the stand has bad ergonomics, as it only allows for tilt adjustments.
With a 4k resolution, images look incredibly sharp on this 27 inch screen. Motion handling is great, input lag is low, and it comes with native FreeSync support, which is good for those with an AMD graphics card or an Xbox One X. The only downside is that the refresh rate is limited to 60Hz, but given the difficulty in pushing high frame rates at 4k, this shouldn't be a problem for most people. Also, like most IPS panels, this monitor doesn't look good in dark environments due to its low contrast ratio and bad black uniformity.
Being a budget monitor, there aren't many extra features to speak of. It has a black stabilizer feature that can help see objects in very dark scenes, as well as a super-resolution feature, which is used for upscaling lower resolution content. It may not be the most feature-packed monitor out there, but for the price, it's worthy of consideration.
