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 9 4k monitors, and below are our picks for the top 5 that are available for purchase in 2018.
The LG 27UK650 is the best 4k monitor that we've tested so far. It is a very good IPS monitor with excellent low input lag, wide viewing angles, and good picture quality. The 27", 4k screen is great for office work, as it is much easier to multitask. LG includes software that makes it a breeze to multitask, as you can split the monitor into multiple virtual displays.
The 4k screen on the UK650 is great for gaming, although some gamers may find the 60 Hz refresh rate too limiting. It also supports FreeSync, which is great, making it a great choice for Xbox One S/X gamers that prefer gaming on a smaller screen.
Unfortunately, although the 27UK650 supports HDR, there is little benefit to using it as it isn't very bright in HDR and lacks a wide color gamut. Overall, it is a decent monitor that should please most people regardless of intended usage.
If you like the LG 27UK650 but would prefer a larger screen, take a look at the LG 32UD99. There is very little difference in performance between the two monitors, but the 32" screen on the 32UD99 provides nearly 40% more screen real estate. It also has a built-in USB 3.0 hub, great if you will be using it with a laptop as you can keep your keyboard and mouse connected to the screen.
If you want to save a bit of money, the LG 27UD58-B is a cheaper alternative to the LG 27UK650. The 27UD58-B is a decent 4k monitor. Compared with the 27UK650, it has a fixed stand that isn't as easy to place in an ideal viewing position, and it doesn't support HDR. It isn't as bright, but there shouldn't be any issues with it, unless your room has a lot of natural lighting. Like the 27UK650, the 27UD58 has a standard 60 Hz refresh rate, and it supports FreeSync, great for gaming.
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, 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 60 Hz 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.
If you often work in a dark room, the LG 32UD59-B is the best 4k monitor for a dark room that we've reviewed so far. It is a decent 4k VA monitor with good gaming performance thanks to the low input lag and FreeSync support.
The 32UD59-B delivers decent picture quality, but is best suited for a dark room. It has a very good native contrast ratio, so blacks appear black in a dark room, but it isn't very bright and might not be able to overcome glare in a bright office.
Unfortunately, it doesn't support HDR, and due to the VA panel, it doesn't have very wide viewing angles and is best enjoyed from the front. Overall, it is a decent 4k monitor that should please most people.
