Although 4k TVs are becoming very common, 4k monitors are just starting to become more mainstream. Whether you're 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 76 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's a very good 4k monitor that should please most users.
If you like the LG 27UK650-W but are looking for a larger screen, the best 32 inch 4k monitor we've tested is the LG 32UD99-W instead. The larger 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.
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's 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's great and should please most people.
The BenQ EW3270U is the best 4k monitor for a dark room that we've tested so far. It's a good 4k monitor for most uses, delivering decent overall picture quality, very good motion handling, and outstanding low input lag, great for a responsive desktop experience. It also has a decent selection of inputs, including 2 HDMI ports, so you shouldn't have any issues connecting all of your devices at once.
This monitor looks better than the LG 27UK650-W in a dark room, thanks to the good contrast ratio and decent black uniformity. It supports HDR, but this doesn't add much as it can't get very bright in HDR, although it can display a wide color gamut.
Unfortunately, this monitor doesn't have the wide viewing angles found on IPS monitors like the LG, so it's best enjoyed from directly in front, at a comfortable viewing distance. Overall, though, this is a good monitor for most uses.
If you want something a bit cheaper than the BenQ EW3270U for a dark room, check out the LG 32UD59-B. Overall, there is very little difference between these two monitors. The LG doesn't support HDR, but this doesn't add much to the BenQ anyway. The stand on the LG has a great height adjustment range, which is much better than the BenQ's stand that can only tilt.
