The 4K monitor is an incredible part of your PC gaming setup. Why spend hundreds of pounds on your gaming desktop if you're going to play it through a 20-year-old faulty monitor? You probably shouldn't.  

Instead, invest in a 4K gaming screen to make the most out of your favourite AAA titles. The 4K gaming monitors have refined what is possible regarding refresh rates and visual clarity. These monitors deliver sharp, precise visuals that standard-resolution monitors cannot match.  

These monitors are a more enticing prospect than ever because of the consistently falling price ranges. They can quickly render images in staggering detail, with an ultra-smooth motion to boot, so it's easy to get why they are becoming the mainstays of PC gamers. So, do yourself a favour and add a 4K monitor to your gaming rig if you still haven't. Trust us, you'll get much more than that traditional screen or the best affordable gaming laptop you've spent money on.  

Additionally, when buying a monitor, you'll want to align the PC specifications with your monitor to make the most out of it. A 4K gaming display with faster refers rates will be wasted if your desktop packs an outdated GPU or CPU. To help you choose the ideal monitor for you – whether you are seeking an affordable option, one with a lower response time, or something with high HDR or adaptive sync– we've collected some of the best 4K monitors available in the market. Under the hood, you can follow our "4K monitor buying guide" to make an informed decision.

ASUS TUF Gaming is a gamer powerhouse designed for extended excellence. With a 28-inch 4K display and Nvidia G-Sync support, it offers a remarkable experience.

It also offers DCI-P3 90% colour gamut, which feels very good with the 5ms response time.  

Head in the game, and the good news continues. ASUS integrate GameVisual Technology with seven pre-set display modes to optimise visuals for different gaming titles. You can access this unique feature through a hotkey or the onscreen display settings menu.  

On the other hand, ASUS Shadow Boost technology makes dark areas darker without overexposing brighter areas, making it easy for you to expose enemies in fast-paced games. Likewise, the Flicker-free technology ensures your eyes remain strain-free in long gaming sessions.

The OLED panel adds a higher refresh rate, an anti-glare coating, and more game-friendly accoutrements.  

The main question is whether this monitor is worth its high price tag. So yes, it does a few things better for the premium at this price point. Firstly, it comes with a 138Hz refresh rate, which various gamers appreciate, packing one of the best graphics cards.  

The addition of true 10-bit colour depth and a cinema-grade 98% DCI-P3 gamut delivers unparalleled realism. The monitor calibrates with Delta E < 2 to ensure the best colour reproduction.

How to Choose the Best 4K Gaming Monitor?

It would be best to consider different factors when choosing the right 4K monitor. Bear in mind which monitor size is suitable for you. Usually, 34 inches or above with the panel type (VA, IPS or TN) is ideal for your needs. 

Pay attention to the connectivity you want, like HDMI inputs, DisplayPort, and USB connections, especially if you plan to connect your monitor with various gaming peripherals. Refresh rates are the key feature to focus on. Go for 120 to 144 Hz to avoid screen tearing and motion blur. 

Of course, if you intend to use your monitor for creative workflows, you should consider one with excellent colour accuracy, higher brightness nits and great HDR chops. G-Sync and Free-Sync are also worthy considerations. If you want the minimum input lag possible and don't mind tearing, then the FreeSync standard is the way to go. On the other hand, if you love smooth motions without tearing and can compromise on input lag, a 4K monitor with G-Sync is the right choice.  

Finally, evaluate the price. Many 4K screens range from £100 to £1000. However, if you are on a budget, consider whether buying a high monitor that will meet your evolving needs or a lower-end monitor that you can replace is also an option. At lower prices, you may get a bit less quality of performance, but if you can afford to splurge, the kitted-out models are definitely worth the  hefty price.
