Before we get to the list of the best 4K monitors available right now, we've also supplied some clear and concise buying advice and tips, so be sure to get the knowledge you need before pulling the trigger.

How to choose the best 4K monitor for you

The natural successor to 1080p screens and televisions is undoubtedly 4K, which is also marketed as Ultra HD (UHD). There are four times as many pixels, which means four times as much detail.

Movies look good at 1080p, but in 4K the picture is utterly breath-taking. And as long as your PC can handle the processing demands, playing games on a 4K display is an amazing experience, too.

When choosing a monitor, you need to take into consideration factors like colour gamut and response time. Response time is a reflection on how good the panel will be for gaming and the faster the better. 

You also - naturally - need to work out which panel size you need. 27-inch displays are the sweet spot for us, although you can get some cracking deals on larger displays, too.

With all that in mind, here's our roundup of the best 4K monitors currently on the market.

+Outstanding best-in-class colour accuracy+Extra features including hardware calibration tool and monitor hood
Reasons to avoid

Eizo displays are a familiar sight in professional photography and video production studios, due to the company's well-deserved reputation for outstanding consistent colour accuracy, with very little brightness deviation across the panel.

The 31-inch ColorEdge CG318-4K continues this tradition, with not just full sRGB coverage, but 99% of the Adobe RGB spectrum and 98% DCI-P3. It fully supports 10-bit colour, taken from a 16-bit look-up table.

Unlike other 4K displays, the CG318-4K has a 4,096 x 2,160 resolution. This reflects the different, slightly taller 4K standard used in digital video production, compared with the 3,840 x 2,160 resolution used in most computer displays.

It goes further still – there's a built-in calibration tool to constantly keep the colours as accurate as possible, which pops across the screen every time it's powered on, along with a bundled monitor hood.

All these features come together to produce a jaw-dropping image, matched only by its asking price. At around £4000, this serious piece of image editing hardware commands a seriously high premium.

While it costs a lot less than Eizo's offering, it's still a pricey prospect, as expected of a large high-end 4K display.

The ROG Swift PG27AQ has an IPS panel, 178 degree viewing angles, and also delivers G-Sync adaptive-sync technology, which reduces the screen tearing and micro-stutter that you often get in games.

G-Sync only goes up to 60Hz rather than the 144Hz seen on other non-4K displays, but it still looks great in games, with extremely fluid animation and minimal ghosting, thanks to a 4ms response time. The screen offers excellent contrast and good brightness, and it's also a 10-bit panel for superb colour accuracy.

And like other ROG Swift displays, the on-screen menus are controlled with a small red joystick behind the monitor, letting you quickly flick through settings. If you're looking for a 4K monitor for both work and play, then this is among the very best on the market.

5. Acer Predator XB281HK

A well-priced, gamer-focussed 4K display with Nvidia G-Sync

Specifications
Screen size: 28-inch
Resolution: 3840 x 2160
Refresh rate: 60Hz
Panel technology: TN
Inputs: 1 x DisplayPort
USB: 4 x USB 3.0
Reasons to buy
+G-Sync up to 60Hz+1ms response time
Reasons to avoid
-Narrow viewing angles compared with IPS screens

Like the Asus ROG Swift PG27AQ, Acer's Predator XB281HK is a 4K monitor with G-Sync technology ensuring no tearing or stuttering in games up to 60Hz.

It uses a TN panel, which can't offer the same wide viewing angles of IPS displays, but it makes this monitor a lot more affordable than the Asus ROG Swift. Indeed, the XB281HK is nicely priced for a general 4K display, so the inclusion of G-Sync is an impressive addition.

Being based off TN technology also means a lower 1ms response time, which is essential for the most serious of gamers.

While colour accuracy should be good since it's a 10-bit panel as well, this AOC display also offers a 4ms G2G response time for gaming, too.

Furthermore, it has a flexible stand with pivot, tilt and swivel, and height adjustment.

As the screen is really designed for professionals, it also comes with a darkroom, CAD/CAM, and animation mode, keyboard video mouse and embedded SD/MMC card reader with support for SD/SDHC/SDXC/MMC.

It certainly costs a pretty penny, and isn't much of a looker, but when its base functionality and features are so good, that doesn't matter so much if you are in the market for a top 4K monitor.

A cracking 4K screen for creative professionals, the Asus ProArt PA329Q leaves little to be desired.

Reasons to buy
+Great colour accuracy+Wide range of inputs
Reasons to avoid
-Pricier than general-purpose displays-No G-Sync or FreeSync technology

Asus has two lines of high-end display. The ROG Swift 4K display offers G-Sync, a feature that will appeal to gamers because of its elimination of screen tearing during 3D animation, but the Pro Art line competes with professional colour-accurate screens.

The PA329Q is the 2015 upgrade of the company's flagship 4K professional display, with a 10-bit IPS panel that now supports a 16-bit colour look-up table and quoted 100% Adobe RGB coverage, with support for the DCI-P3 colour spectrum as well.

If you've got very little to spend but still need a 4K monitor then the Iiyama B2888UHSU is perfect for you.

9. Iiyama B2888UHSU

The best 4K monitor for a bargain basement price point

Specifications

Resolution: 3840 x 2160
Refresh rate: 60Hz
Panel technology: TN
Inputs: 2 x HDMI, 1 x DisplayPort, 1 x Mini DisplayPort, 1 x VGA, 1 x DVI
USB: 4 x USB 3.0
Reasons to buy
+Very affordable 4K display+Picture-in-picture mode
Reasons to avoid
-Narrow viewing angles with TN panel-Not all video inputs are capable of 4K at 60Hz

Since 4K is still quite a new technology, most of the displays in this list are pricier than a lot of non-4K displays – but Iiyama's 28-inch B2888UHSU is a lot more reasonable.

It uses a TN panel with a 1ms response time, and although the viewing angles aren't quite as wide as you'll find with an IPS display, there are plenty of small extras that make the B2888UHSU a really good buy.

It has a copious number of video inputs for example, a fully adjustable stand, and a picture-in-picture mode, as seen with other larger displays, so you can use two devices simultaneously with this monitor.
