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 in 2019. 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

    Usage Ratings - Version 1.0

    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, however, 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. For those who like to game in a dark room, you 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
    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 LG 27UK650-W is the best 4k gaming monitor for most people, but if you need something bigger, then go with the LG 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 tradeoffs, 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 LG 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 LG 32UD59-B.

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

    Usage Ratings - Version 1.0
    8.1
    Gaming
    Size : 27"
    Resolution : 3840x2160
    Refresh Rate : 120 Hz
    LCD Type
    :
    IPS
    Variable Refresh Rate
    :
    G-Sync

    The best 4k gaming monitor with G-SYNC support we've tested so far is the Acer Predator X27. It's a great IPS monitor overall with good picture quality, wide viewing angles, and good peak brightness, making it suitable for a bright room.

    Gamers will appreciate the 120Hz refresh rate and the fast response time that delivers fast-moving content with almost no blur trail. This monitor supports NVIDIA's G-SYNC for a very wide range of refresh rates, ensuring a tear-free gaming experience. Also, if you play a lot of HDR games, you should note that it offers the best HDR experience of the monitors we've tested so far, mainly due to the excellent HDR peak brightness. The remarkable color gamut is also the best we've tested so far.

    Unfortunately, the monitor, just like most IPS monitors, doesn't deliver good dark room performance; blacks look gray due to the lacking contrast ratio and poor black uniformity, despite the existence of a local dimming feature that can't help much. Overall, this is an expensive monitor that delivers great performance in most uses and will satisfy those who choose it.

  5. Cheaper Alternative: Acer Predator XB273K

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

    Although the Acer Predator X27 is a great gaming monitor, if you want something cheaper, the Acer Predator XB273K is a great alternative. This monitor has an excellent response time, outstanding low input lag, and it also supports G-SYNC. It's a bit less versatile than the other monitor, though, as it doesn't have the full array local dimming feature, has worse gradient performance, and is significantly less bright in HDR.

    Overall, the Acer Predator X27 is a better choice and a more versatile monitor, but if you want to save some cash without much compromise in gaming performance, the Acer Predator XB273K is a good alternative.

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

    Usage Ratings - Version 1.0
    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. It has a similar design to the LG 27UK650-W, but with a black finish and a stand that isn't as versatile since it doesn't allow many ergonomic adjustments. On the upside, this monitor delivers a good gaming performance thanks to its very low input and FreeSync support that ensures tear free-gaming. The response time is slightly slower than the other LG monitors, and some people might notice a little more blur in fast-motion.

    When compared to other LG monitors, it's lacking HDR support, which doesn't add much anyway.

    Overall, this is a good 4k gaming monitor that will please most casual gamers.
