It is not without quirks: the screen brightness could be higher, the red on black trim is an acquired taste, and it has no built-in speakers. On the other hand, you get amazing picture quality, quick response time, accurate color performance, multiple ports, and a versatile stand for multiple viewing angle options. Its most notable feature is AMD FreeSync to prevent tearing and ensure that your games are running smoothly. Of course, the picture-in-picture and picture-by-picture modes are also helpful because who doesn’t multitask nowadays.

8. AOC U2879VF

The most affordable 4K monitor for gaming

Screen size: 28-inch | Aspect ratio: 16:9 | Resolution: 3,840 x 2,160 | Brightness: 300 cd/m2 | Response time: 1 ms | Contrast ratio: 1,000:1 | Color support: 1.07 billion

4K gaming at 144fps
Fastest 1ms response time 
Narrow viewing angles

IPS displays may offer better viewing angles and color representation, but a good TN panel makes for a much better gaming monitor, thanks to much faster response times, higher refresh rates and affordability. This is why the AOC U2879VF has a 1ms response time and a refresh rate of 144Hz refresh rate for a low price. If you can forgive the restricted viewing angles, the occasional flickering at 144Hz, the absence of a USB port, and the ho hum color performance, this AMD FreeSync enabled monitor is for you.

9. Acer Predator X27

4K, HDR and 144Hz? Oh my!

Screen size: 27-inch | Aspect ratio: 16:9 | Resolution: 3,840 x 2,160 | Brightness: 1,000 cd/m2 (peak) | Response time: 4 ms | Contrast ratio: 1,000:1 | Color support: 16.7 million

Great HDR
High refresh rate
Very expensive

If you have an absolute beast of a gaming computer – think two Nvidia RTX 2080 Tis in SLI – and you need a monitor that can keep up, you might want to take a look at the Acer Predator X27. Not only is it a 27-inch 4K monitor with HDR, but it also has a refresh rate of a whopping 144 Hz. If you have the horsepower, you can play games in 4K competitively without losing an edge to the person playing in 1080p. But, as you may expect from a spec sheet like this, it’s very expensive – but if you need the tech, it’s definitely there.

10. LG 43UD79-B

A hefty display with even heftier features

Screen size: 42.51-inch | Aspect ratio: 16:9 | Resolution: 3,840 x 2,160 | Brightness: 350 cd/m2 | Response time: 5 ms | Contrast ratio: 1,000:1 | Color support: 1.07 billion

Massive 42-inch panel
Multiple screen splitting options
Tough to fit on small desks
Very expensive

You’ll need a bigger desk with 43UD79-B’s hefty, 42-inch screen. Unfortunately this bigger than life screen might also be darker around the edges and a sluggish refresh rage. However, this 4K monitor’s other features will more than make up for its flaws. The screen split software, for one, allows for a range of screen configurations. This, coupled with its four HDMI inputs, a DisplayPort 1.2a port, and a USC-C port, will let you effortlessly run multiple devices at once. Along with its true IPS screen, color-rich display, and FreeSync compatibility, you might just be getting a bargain.
