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 68 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-W 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.

    This 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, this monitor 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-W but are looking for a larger screen, check out the LG 32UD99-W instead. The larger 32" screen is ideal for multitasking, and it 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, the best budget 4k monitor is the LG 27UD58-B. This is a decent 4k monitor with a simple stand, decent picture quality, good motion handling, and low input lag. Unlike the LG 27UK650, this monitor doesn't support HDR, but this doesn't change much. It has excellent gradient handling and an excellent SDR color gamut.

    G-Sync

    If you want the best HDR experience, the Acer Predator X27 has the widest color gamut of any 4k monitor that we've reviewed so far. It's a great choice if you do a lot of professional photo or video editing in the wider Adobe RGB color space. This monitor is also extremely bright and has excellent motion handling, making it one of the most versatile monitors that we've reviewed so far.

    It 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 the majority of 4k monitors currently available, it is limited to a 60Hz refresh rate.

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

  5. Best 4k Monitor For A Dark Room: BenQ EW3270U

    Usage Ratings - Version 1.0

    :
    FreeSync

    If you want better dark room performance, check out the BenQ EW3270U. It is a good 4k monitor that delivers decent overall picture quality, with a very good native contrast ratio, great gray uniformity, and decent black uniformity. It has decent motion handling for gaming or watching videos, with excellent response time, a flicker-free backlight, and it supports AMD's FreeSync variable refresh rate technology.

    This monitor also supports HDR and can display a wide color gamut, but it can't get as bright as the LG 27UK650-W, so small highlights in some HDR content don't stand out as much as they should. There's also an optional HDR simulation mode, similar to HDR+ found on some Samsung TVs, but we don't recommend using this.

    Unfortunately, the image on this monitor degrades when viewed at an angle, so it isn't as good of a choice if frequently share your screen with someone else. Overall though, this is a good monitor for most uses.

    If you want a good dark room monitor, but find the BenQ EW3270U too expensive, check out the LG 32UD59-B instead. Overall, the two monitors are very similar. This monitor doesn't support HDR, but has slightly better vertical viewing angles than the BenQ. It also has slightly better ergonomics, although some people might still find them too limiting. Overall, this is a decent 4k monitor for most uses.
