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 85 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 want something cheaper than the LG 27UK650-W, check out the LG 27UD58-B instead. It's a simpler model, with no support for HDR, bad ergonomics, and worse black uniformity, but it has similar motion handling and low input lag, great for gaming, and it supports FreeSync for a nearly tear-free gaming experience.
Although the 27UK650-W is the best 4k monitor for most people, if you want to save a bit of money and don't mind compromising on ergonomics, the 27UD58-B is a decent alternative.
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 plan on using your monitor in a dark room, the BenQ EW3270U might be a slightly better choice than the LG 32UD99-W. This VA monitor has much better contrast, resulting in deeper blacks, and it has slightly better black uniformity. It's a bit less versatile, though, as the image degrades when viewed at an angle and it has very limited ergonomics, so it might be difficult to place it in an optimal viewing position.
Overall, the LG 32UD99-W is more versatile, a better choice for most people, and the best 32 inch 4k monitor, but if you want your monitor to look the best in a dark room, the BenQ EW3270U might be a better choice.
If you want something cheaper than the LG 32UD99-W, check out the LG 32UD59-B instead. 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 LG 32UD99-W is a much better monitor for most people, but it's also very expensive. If you want to save some money, the LG 32UD59-B is a more basic, but decent choice.
