Although 4k TVs are becoming very common, 4k monitors are just starting to grow in popularity. 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 over 100 monitors, and below are our recommendations for the best 4k monitors that are available for purchase. See our recommendations for the best 4k gaming monitors, and the best 1080p and 1440p monitors.
The best 4k monitor we've tested so far is the LG 27UK650-W. The 27 inch screen and high resolution allows you to open plenty of windows while you're working and the out-of-box color accuracy is great, so content will look how the creator intended it to be. This monitor can get really bright and it does a decent job at handling reflections, so you can place it in any bright environment, like an office.
Casual gamers will appreciate the great response time, with minimal blur trail behind fast-moving objects, and the extremely low input lag. It supports FreeSync variable refresh rate technology, but it can only go as low as 40Hz and as high as 60Hz, which might disappoint some more serious gamers. Like most IPS panel monitors, it has fantastic viewing angles, so it's a great monitor for co-op gaming or if you need to share work with others, but that comes at the cost of a good contrast ratio, which is mediocre. On the upside, it has excellent gray uniformity, so solid colors on the screen, like on a web page, will appear uniform with no obvious shading.
This monitor offers a great picture quality, making it the best 4k monitor we've tested so far.
If you need something a bit cheaper, take a look at the LG 27UD58-B. It has the same size and resolution as the LG 27UK650-W; however, it doesn't support HDR, the ergonomics are disappointing, and dark room performance is noticeably worse, as contrast ratio is mediocre and black uniformity is sub-par. On the upside, out of the box color accuracy is slightly better and it still has a lot of great features, such as a flicker-free backlight, great motion handling, low input lag, as well as support for FreeSync variable refresh rate.
Overall, the 27UK650-W is a better monitor, but if you don't mind a few compromises, the 27UD58-B is a decent choice for those shopping on a budget.
If you want the best HDR experience, the Acer Predator X27 is one of the best 4k monitors we've tested that supports HDR. It has an impressive color gamut, making it 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's a great gaming monitor as well, with excellent low input lag and a fast response time. It has excellent wide viewing angles, perfect for co-op gaming. The monitor also supports G-SYNC and has a wider refresh rate range than the vast majority of 4k monitors on the market, though you'll need a very powerful graphics card to take advantage of it.
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 LG 32UD99-W is the best 32 inch 4k monitor that we've tested so far. It's a versatile 4k monitor with wide viewing angles, excellent low input lag, and some great gaming features. It has a fast response time for clear motion, and it supports AMD's FreeSync variable refresh rate technology for a nearly tear-free gaming experience.
This monitor also has a few great additional features. It can display the image from two sources at once in a picture-by-picture mode, and it has a built-in USB hub. The USB-C upstream port also supports power delivery, great for MacBook owners, so you can charge your device while you work and leave your other USB-C ports free.
Unfortunately, like most IPS monitors, it doesn't look as good in a dark room, as it has a low contrast ratio. Overall, this is a great monitor for almost any use.
If you're looking for a monitor that performs better in dark rooms, then check out the BenQ EW3270U. With a VA panel, it doesn't have the same wide viewing angles as the LG 32UD99-W's IPS panel, but it has a much better contrast ratio and better black uniformity. The BenQ also has better gaming features with a good response time and a fantastic low input lag, so with the 4k resolution, you'll have an immersive gaming experience. Unfortunately, this monitor doesn't perform very well in bright rooms with decent SDR peak brightness, but it still has good reflection handling if you choose to put it in a bright environment.
If you're looking for the best 32 inch 4k monitor we've tested so far, consider the LG, but if you want a dark room alternative, look into the BenQ.
If you want something cheaper than the LG 32UD99-W, check out the LG 32UD59-B. Like the BenQ EW3270U, this monitor has a VA panel, so it looks better in a dark room but has worse viewing angles. This monitor doesn't support HDR, and it has limited ergonomics, but the large, high-resolution screen is great for multitasking, and it delivers good overall gaming performance.
Overall, the 32UD99-W is a much better monitor for most people, but it's also very expensive. If you want to save some money, the 32UD59-B is a more basic, but decent choice.
