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 75 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

    Gaming

    Resolution : 3840x2160
    Refresh Rate : 60 Hz

    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
    :
    IPS
    Variable Refresh Rate
    :
    FreeSync

    If you find the size of the LG 27UK650-W limiting and want a larger monitor, then get the LG 32UD99-W. The two monitors have very similar performance, although HDR content does look slightly better on the larger one, which can also display a wide color gamut. Both monitors support FreeSync for tear-free gaming, and the response time is excellent, so fast-moving content has almost no blur trail. This monitor has a built-in USB hub and a USB-C port that supports power delivery and DisplayPort Alt Mode.

    Overall, while the LG 27UK650-W is the best 4k gaming monitor for most people, if you want something larger and cost isn't an issue, then the LG 32UD99-W is a better choice.

  3. Dark Room Alternative: LG 32UD59-B

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

    If you often game in a dark room and don't like that blacks look more like gray on the LG 27UK650-W, then get the LG 32UD59-B. You won't get the HDR support nor the wide viewing angles of the other LG. Also, the response time, although still fast, isn't as good as on the other monitor; this means you'll notice a little more blur behind fast-moving content. On the upside, if you sit straight in front and viewing angles aren't an issue, you'll enjoy deep blacks in a dark room, thanks to the monitor's good contrast ratio.

    Overall, if you want the best gaming experience, then get the LG 27UK650-W; however, if dark room performance is very important to you and you don't mind compromising on viewing angles and response time, then the LG 32UD59-B will do a better job provided you sit straight in front.

  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, the LG 27UD58-B is lacking HDR support, which doesn't add much anyway.

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