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 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 110 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. It has a 27-inch IPS screen that delivers sharp images and text, with plenty of screen real estate to have multiple windows opened at the same time. It has an impressive peak brightness and decent reflection handling, so visibility shouldn't be an issue unless you're in a very bright room. The stand lacks swivel adjustment; however, its wide viewing angles make it easier to share your work with colleagues. Its out-of-the-box color accuracy is great, but it can't display a wide color gamut despite having HDR support.
Although this monitor is primarily designed for office use, it performs quite well when it comes to gaming. It has a fast response time, low input lag, and it supports FreeSync variable refresh rate to reduce screen tearing. The refresh rate is limited to 60Hz, but given the difficulty in achieving a high frame rate at a native 4k resolution, it shouldn't be a problem for most people.
Unfortunately, the contrast ratio is quite low, which is expected of most IPS monitors. Additionally, there's severe clouding throughout the screen that can be quite distracting when viewed in the dark. That said, screen uniformity can vary per unit, so your mileage may vary. It has few extra features, but on the bright side, the flicker-free backlight can be helpful on those long work days. On the whole, this is a versatile monitor that most people should be happy with.
If you're shopping on a smaller budget, then check out the LG 27UD58-B. It doesn't look as stylish as the LG 27UK650-W with its thick bezels and cheap-looking stand, but you still get a large 27-inch screen, a 4k resolution, and decent viewing angles thanks to its IPS panel. There are a few compromises, of course, as its ergonomics are terrible and it has a low peak brightness, making it less ideal for bright rooms. Its response time is just as good, input lag is low, and it also supports FreeSync if you want to do some gaming on the side.
Overall, the 27UK650-W is a better choice for most people, especially if you plan on using it in a bright environment or if you need good ergonomics. However, if cost is a concern and you don't mind compromising a bit, the 27UD58-B is a pretty decent choice.
The Acer Predator X27 is one of the best 4k monitors we've tested if you want the best HDR experience. It has an impressive color gamut with excellent coverage of the DCI P3 color space used in most HDR content. It also has the best coverage of the Adobe RGB color space we've seen so far, making it an excellent choice for photo editors.
It's a great gaming monitor as well, with excellent low input lag and fast response time. It has excellent wide viewing angles, perfect for co-op gaming. It also supports G-SYNC and has a wider refresh rate range than the vast majority of 4k monitors on the market, though you need a very powerful graphics card to take advantage of it. It's also extremely bright and has excellent motion handling, making it one of the most versatile monitors that we've reviewed so far.
Unfortunately, it 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 it's very expensive, it's still one of the best 4k monitors for HDR we've seen so far and should please most people.
The best 32-inch 4k monitor that we've tested so far is the LG 32UD99-W. This is a good monitor for those who like the traditional 16:9 aspect ratio but still want enough screen real estate to have multiple windows opened at the same time. Its 4k resolution keeps text looking sharp and legible, and its excellent low input lag provides a responsive desktop experience. If you want to do some gaming on this monitor, it supports FreeSync to reduce screen tearing, but it also has a limited 60Hz refresh rate.
For most bright rooms, it has a great peak brightness that fights glare easily; however, its reflection handling is sub-par, so it's best to avoid direct sources of light shining on the screen. It has a decent color accuracy right out of the box, with full coverage of the sRGB color space, and it supports HDR. Images remain accurate when viewed from the side thanks to its IPS panel's wide viewing angles, but its low contrast ratio results in blacks that look like gray.
Like many ultrawide monitors, it supports a Picture-by-Picture mode that allows you to display an image from two sources simultaneously. Its USB hub also includes a USB-C port with DisplayPort Alt mode, so you can use it as a second monitor for a compatible device like a MacBook Pro and charge it with a single cable. All in all, if you want a large 16:9 monitor with a 4k resolution, you should consider this one.
If you're looking for a monitor that performs better in dark rooms, 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. It also has better gaming features with good response time and excellent low input lag, so with the 4k resolution, you'll have an immersive gaming experience. Unfortunately, it 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 find the LG 32UD99-W a bit too expensive, there's a cheaper option, the LG 32UD59-B. It also has a 32-inch screen, a 16:9 aspect ratio, and a 60Hz refresh rate. However, this monitor uses a VA panel, which has a much higher contrast ratio to produce deeper blacks, but its viewing angles are significantly worse. It should perform fine in most rooms, as it has an okay peak brightness and decent reflection handling, but it may be an issue in very bright rooms. Unfortunately, this monitor has rather poor ergonomics, with only height and tilt adjustments available, and it doesn't support HDR. That said, it still has a 10-bit panel with outstanding gradient handling and good out-of-the-box color accuracy.
Overall, the 32UD99-W has many more features and performs better in general, but if you're shopping on a tight budget, the 32UD59-B is a good alternative.
