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 90 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.


  1. Best 4k Gaming Monitor: LG 27UK650-W

    7.8
    Gaming
    Size 27"
    Resolution 3840x2160
    Max Refresh Rate
    60 Hz
    LCD Type
    IPS
    Variable Refresh Rate
    FreeSync

    The LG 27UK650-W is the best 4k gaming monitor that we've tested so far. Although this 27 inch monitor has a clean and simple design that fits better in an office setting, it can handle gaming pretty well. It doesn't have the fastest refresh rate at 60Hz, but the outstanding response time and input lag make this monitor great for gaming. If that's not enough, LG also included support for FreeSync, which provides a nearly tear-free gaming experience. Those with a recent NVIDIA 10- or 20- series graphics card can also take advantage of this technology with a driver update.

    If you're looking for the best HDR experience, you won't find it here. While the monitor does support HDR, the experience is limited by the mediocre peak brightness and lack of wide color gamut. Those who like to game in a dark room may be disappointed by the IPS panel's poor contrast ratio and subpar black uniformity.

    There are some advantages to LG's choice of IPS technology, though, as they're well-known to have wide viewing angles and great color accuracy out-of-the-box. All in all, if you're looking for a great 4k gaming monitor at a decent price, this is our top pick.

  2. Larger Alternative: LG 32UD99-W

    Size 32"
    Resolution 3840x2160
    Max Refresh Rate
    60 Hz
    LCD Type
    IPS
    Variable Refresh Rate
    FreeSync

    If the LG 27UK650-W's size is too small for an immersive gaming experience, then consider the LG 32UD99-W. Both monitors will perform similarly, but there are some notable differences. This larger monitor is capable of displaying a wide color gamut and can get brighter, which results in better HDR performance. Another welcome addition is the USB 3.0 hub and USB-C port, which allows users to display an image from a portable device while charging at the same time. Although this monitor isn't a great performer in dark rooms, either, it still performs slightly better in regards to contrast ratio and black uniformity.

    Overall, the 27UK650-W is the best 4k gaming monitor for most people, but if you need something bigger, go with the 32UD99-W.

  3. Dark Room Alternative: LG 32UD59-B

    Size 32"
    Resolution 3840x2160
    Refresh Rate 60 Hz
    LCD Type
    VA
    Variable Refresh Rate
    FreeSync

    If you're looking for a monitor with good dark room performance, the LG 32UD59-B is better than the LG 27UK650-W. The VA panel on this monitor has a much higher contrast ratio and better black uniformity, resulting in deeper blacks. There are some trade-offs, though: the peak brightness is lower, there isn't any HDR support, and the viewing angle isn't as wide. Other minor differences are in regards to motion handling, which is slightly inferior, but still good enough for gaming purposes.

    Overall, the 27UK650-W is a better choice if you're after the best gaming experience. However, if you want a monitor that has better dark room performance, then consider the 32UD59-B.

  4. Best G-SYNC 4k Monitor: Acer Predator X27

    8.1
    Gaming
    Size 27"
    Resolution 3840x2160
    Max Refresh Rate
    144 Hz
    LCD Type
    IPS
    Variable Refresh Rate
    G-SYNC

    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 impressively 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 slightly 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. 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.

    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. Overall, this is a no-compromise monitor that should satisfy even the most demanding gamers.

  5. Cheaper Alternative: Acer Predator XB273K

    Size 27"
    Resolution 3840x2160
    Refresh Rate 120 Hz
    LCD Type
    IPS
    Variable Refresh Rate
    G-Sync

    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 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 mediocre, 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.

  6. Best Budget 4k Gaming Monitor: LG 27UD58-B

    7.6
    Gaming
    Size 27"
    Resolution 3840x2160
    Refresh Rate 60 Hz
    LCD Type
    IPS
    Variable Refresh Rate
    FreeSync

    The best budget 4k gaming monitor we've tested so far is the LG 27UD58-B. This monitor follows a very familiar LG design with its arc-shaped stand, except that it has much thicker bezels, which is less ideal for multi-monitor setups. Build quality is decent, even though it's entirely made of plastic, 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. 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.
