Although 4k TVs are becoming very common, 4k monitors are just starting to become more mainstream. Whether you are looking for a better multitasking experience for work or just want a more immersive gaming experience, 4k monitors have a lot to offer. Although they used to be very expensive, they have recently started to drop in price as 4k becomes more popular and more devices support it.

We've reviewed 64 monitors and below are our recommendations for the best 4k monitors that are available for purchase in 2019. See our recommendations for the best 4k gaming monitors, and the best 1080p and 1440p monitors.

    The LG 27UK650 is the best 4k monitor that we've tested so far. It has a good design, with a good height adjustment on the stand and a decent tilt range. Performance-wise, it delivers good overall picture quality, with great wide viewing angles, and has great motion handling and excellent low input lag.

    The 27UK650 is also a great gaming monitor. It has an excellent response time, delivering clear motion with very little blur, and the backlight is completely flicker-free. It also supports AMD's FreeSync variable refresh rate technology, even on 10- and 20- series NVIDIA graphics cards with NVIDIA's new Adaptive Sync drivers.

    Unfortunately, the 27UK650-w doesn't look as good in a dark room, and the 60Hz refresh rate may be disappointing to some. Overall, it is a very good 4k monitor that should please most users.

    If you like the LG 27UK650 but are looking for a larger screen, check out the LG 32UD99 instead. The larger 32" screen is ideal for multitasking, and the 32UD99 performs nearly identically to the smaller model. It has a slightly better color gamut and is able to display a wide color range in HDR. It also has better connectivity, thanks to an included USB hub that can be used to connect and charge your accessories, with only one cable going back to your computer.

    If you like the LG 27UK650-W but would prefer something cheaper, check out the LG 27UD58-B instead. The 27UD58 is a decent 4k monitor with a simple stand, decent picture quality, good motion handling, and low input lag. Unlike the 27UK650, the 27UD58 doesn't support HDR, but this doesn't change much. The 27UD58 has excellent gradient handling and an excellent SDR color gamut.

    G-Sync

    If you want the best HDR experience, or often work in the wider Adobe RGB color space, the Acer Predator X27 has the widest color gamut of any 4k monitor that we've reviewed so far. It's also extremely bright and has excellent motion handling, making it one of the most versatile monitors that we've reviewed so far.

    The X27 has an excellent wide color gamut, better even than most TVs, and it covers nearly 100% of the Adobe RGB color space, making it great for professionals that work in the print or marketing industries. It has excellent wide viewing angles and great HDR support. The monitor also supports G-SYNC, but like all current 4k monitors, it is limited to a 60Hz refresh rate.

    Unfortunately, the Acer Predator X27 doesn't look the best in a dark room. It has a disappointing native contrast ratio, so blacks appear gray in a dark room. It does have a local dimming feature, but it isn't very effective. Overall, although the X27 is very expensive, it is a great monitor that should please most people.

  5. Best 4k Monitor For A Dark Room: LG 32UD59-B

    Usage Ratings - Version 1.0

    • 1.0: Fall 2017

    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 are looking for a monitor that will perform well in a dark room, then check out the LG 32UD59-B. It is a decent 4k monitor that delivers deep blacks in a dark room thanks to the high native contrast ratio and the decent black uniformity of its VA panel. It has a low input lag and supports FreeSync for a tear-free gaming experience.

    The picture quality of the 32UD59-B is decent, but the monitor can not get very bright to overcome room glare, so it is best suited for dimmer rooms. It does not offer support for HDR content and, due to its VA panel, the image deteriorates when viewed from the side.

    Overall, it is a decent 4k monitor that should please most people who buy it.
