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 68 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

    Size : 27 "
    Resolution : 3840x2160
    Refresh Rate : 60 Hz
    LCD Type
    What it is: Type of LCD technology used by the monitor.
    When it matters: Different technologies have different viewing angle properties.
    :
    IPS
    Variable Refresh Rate
    What it is: Feature that allows the monitor to synchronize its refresh rate with the input device's output and reduces stuttering and screen tearing.
    When it matters: Almost every usage, but is most noticeable in gaming where constant fluctuation in framerate cause distracting artifacts.
    :
    FreeSync

    The LG 27UK650-W is the best 4k gaming monitor that we've tested so far. It's a great gaming monitor, with great motion handling and excellent low input lag. It has an excellent response time, but as it's limited to a 60Hz refresh rate, there is a bit more noticeable motion blur than monitors with a faster refresh rate.

    It doesn't have much in the way of extra gaming features, but it does have a black stabilizer feature that makes it easier to see dark objects in shadows without affecting bright areas. This monitor also supports FreeSync, for a nearly tear-free gaming experience whether you are gaming on an Xbox One or a PC with an AMD graphics card. It's also compatible with NVIDIA's new Adaptive Sync drivers, as long as you have a recent 10- or 20- series graphics card.

    This monitor also supports HDR, but unfortunately, it has very limited HDR performance. It can't get bright enough to show off specular highlights, and it can't display a wide color gamut. Overall, it's a very good monitor for most uses.

  2. Larger Alternative: LG 32UD99-W

    Size : 32 "
    Resolution : 3840x2160
    Refresh Rate : 60 Hz
    LCD Type
    What it is: Type of LCD technology used by the monitor.
    When it matters: Different technologies have different viewing angle properties.
    :
    IPS
    Variable Refresh Rate
    What it is: Feature that allows the monitor to synchronize its refresh rate with the input device's output and reduces stuttering and screen tearing.
    When it matters: Almost every usage, but is most noticeable in gaming where constant fluctuation in framerate cause distracting artifacts.
    :
    FreeSync

    If you like the LG 27UK650-W but want a larger monitor to game on, then check out the LG 32UD99. The two monitors have almost identical performance, although the latter does perform slightly better with HDR content and can display a wide color gamut. The response time and input lag are excellent, just like the smaller LG and, of course, the monitor supports FreeSync to ensure tear-free gaming. It also has a USB-C port and a USB hub, which is great if your computer has limited connectivity.

  3. Dark Room Alternative: LG 32UD59-B

    Size : 32 "
    Resolution : 3840x2160
    Refresh Rate : 60 Hz
    LCD Type
    What it is: Type of LCD technology used by the monitor.
    When it matters: Different technologies have different viewing angle properties.
    :
    VA
    Variable Refresh Rate
    What it is: Feature that allows the monitor to synchronize its refresh rate with the input device's output and reduces stuttering and screen tearing.
    When it matters: Almost every usage, but is most noticeable in gaming where constant fluctuation in framerate cause distracting artifacts.
    :
    FreeSync

    If you want a monitor that looks a bit better in a dark room, check out the LG 32UD59-B instead. This monitor uses a VA panel and delivers deeper, more uniform blacks, great for dark room viewing. It has a slightly slower response time than the LG 27UK650, which results in a bit more noticeable blur behind fast-moving objects, and the image degrades more rapidly at an angle. Overall, though, it's a very good gaming monitor that should please most casual gamers.

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

    Size : 27 "
    Resolution : 3840x2160
    Refresh Rate : 120 Hz
    LCD Type
    What it is: Type of LCD technology used by the monitor.
    When it matters: Different technologies have different viewing angle properties.
    :
    IPS
    Variable Refresh Rate
    What it is: Feature that allows the monitor to synchronize its refresh rate with the input device's output and reduces stuttering and screen tearing.
    When it matters: Almost every usage, but is most noticeable in gaming where constant fluctuation in framerate cause distracting artifacts.
    :
    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.

    As a gamer, you will appreciate the fast response time that displays fast-moving objects with almost no blur trail, and the 120Hz fast refresh rate. 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 thus 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, does not 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 cannot help much. Overall, this is an expensive monitor that delivers great performance in most uses and will satisfy those who choose it.

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

    Size : 27 "
    Resolution : 3840x2160
    Refresh Rate : 60 Hz
    LCD Type
    What it is: Type of LCD technology used by the monitor.
    When it matters: Different technologies have different viewing angle properties.
    :
    IPS
    Variable Refresh Rate
    What it is: Feature that allows the monitor to synchronize its refresh rate with the input device's output and reduces stuttering and screen tearing.
    When it matters: Almost every usage, but is most noticeable in gaming where constant fluctuation in framerate cause distracting artifacts.
    :
    FreeSync

    If you don't want to spend a lot on a new monitor, the LG 27UD58-B is the best budget 4k gaming monitor that we've tested so far. This monitor is very similar to the LG 27UK650-W, delivering a good overall gaming experience. It has a very similar design, but with a simpler stand that has limited ergonomic adjustments and a black finish.

    In terms of gaming performance, this monitor is very similar to the 27UK650. It has a slightly slower response time, so fast-moving objects have a bit more blur behind them, but it still supports FreeSync and has nearly identical low input lag, which is great.

    Unlike the other LG, this monitor doesn't support HDR, but this doesn't add much anyway. Overall, this is a good 4k gaming monitor, great for casual gaming.
