Large monitors are great for work and play. 34" and larger screens offer more room to multitask, making it easier to see more of your project at once or place multiple windows side-by-side. They also deliver a more immersive gaming experience. From large, TV-like displays to Super Ultra-Wide cinema monitors, these huge displays can significantly transform the way you work and play.

We've reviewed 9 large monitors and below you'll find our picks for the best 34 inch monitors and larger that are available for purchase in 2019. See also our recommendations for the best ultrawide monitors and the best gaming monitors.

    The best large monitor that we've tested so far is the Dell U3818DW. It is a very good 38 inch monitor that is great for office use. It has excellent accuracy out of the box and wide viewing angles, and the large amount of screen real estate is great for multitasking.

    The U3818DW is a high resolution, ultrawide screen with a gentle curve, that makes it easy to work on multiple things at the same time, or to see even more of your project. It also has a unique set of connections that make it easy to work on two computers at the same time, great if you work remotely and want to pair your home and work computer.

    Unfortunately, blacks tend to appear gray in a dark room, and there is noticeable motion smearing caused by overshoot, so it isn't as well suited for gaming or for watching movies. Overall though, it is a very good monitor that should please most people, assuming it fits on your desk.

    FreeSync

    If you want something even larger than the Dell U3818DW, check out the Samsung CHG90. This massive 49" monitor is basically two 16:9 monitors side by side, which is incredible for multitasking, as you can place 3 or 4 windows side-by-side. It also delivers an extremely immersive gaming experience, thanks to the 144 Hz refresh rate and support for FreeSync 2. Unfortunately, the image degrades when viewed at an angle, although the curved screen does somewhat compensate for this, as long as you are sitting directly in front of it.

  3. 4k Alternative: LG 43UD79-B

    Size : 43 "
    Resolution : 3840x2160
    Refresh Rate : 60 Hz

    What it is: Type of LCD technology used by the monitor.

    When it matters: Almost every usage, but is most noticeable in gaming where constant fluctuation in framerate cause distracting artifacts.
    :
    No

    If you would prefer a screen with a true 4k resolution, the LG 43UD79 is a good 4k alternative to the Dell U3818DW. The 43UD79 is a huge 43" monitor that delivers decent overall performance. It is well suited for multitasking in an office setting, but the stand has limited ergonomics, so you might want to VESA mount it. It also has a great selection of inputs, so you can easily use it as a TV and connect your game consoles or media streaming device to it. Unfortunately, it isn't as good for gaming, as it has a limited 60 Hz refresh rate, no variable refresh rate support, and it doesn't support HDR. Overall though, it is a decent 4k monitor.

    The Dell Alienware AW3418DW is the best 34 inch monitor for gaming that we've tested so far. It delivers decent overall picture quality, with wide viewing angles and a large, high-resolution screen. The wide-format screen is excellent for office use, as you can easily display multiple windows side-by-side.

    It is a great gaming monitor. It has an excellent 100 Hz refresh rate, and it supports NVIDIA G-SYNC, for a smooth, tear-free gaming experience. It also has an extremely fast response time, ensuring very little motion blur behind fast moving objects, and it has excellent low input lag, good for even the most advanced gamers.

    Unfortunately, the AW3418DW doesn't look as good in a dark room, and it also can't get very bright to overcome glare in a bright room. Overall though, it is one of the best 34 inch monitors we've tested and it should please most people, regardless of usage.

  5. Cheaper Alternative: LG 34UC79G-B

    Size : 34 "
    Resolution : 2560x1080
    Refresh Rate : 144 Hz
    LCD Type
    What it is: Type of LCD technology used by the monitor.

    :
    FreeSync

    If you want something a bit cheaper than the Dell AW3418DW, the LG 34UC79G-B is a great alternative. Like the Dell, the LG has a great 34" screen, but it has a lower resolution that can't display as many fine details as the AW3418DW. Despite this, it is still a great gaming monitor, thanks to the 144 Hz refresh rate and FreeSync support, ensuring a smooth, tear-free gaming experience. The 34UC79G-B also has great motion handling and an optional black frame insertion feature that can reduce persistence blur. Overall, it is a great gaming monitor that should please even more demanding gamers.
