4K resolution is a common display resolution, often known as 2160p and UHD. The resolution of a display describes how many pixels it has in width x height format. The more pixels on a screen, the sharper the image should be. The Digital Cinema Initiatives (DCI), an organisation of motion picture studios that develops digital cinema standards, defines 4K resolution as 4096 x 2160 (opens in new tab), but this resolution is uncommon in consumer goods. PC monitors, laptops, and TVs labelled as 4K resolution typically have a resolution of 3840 x 2160. However, this resolution is officially referred to as Ultra HD (UHD). UHD/ 4K resolution monitors are frequently seen.
Most recent GPUs (opens in new tab) support UHD/ 4K resolution output, though playing games at this resolution will require a reasonably strong graphics card (opens in new tab). As a result, many gamers prefer to play games in 1080p (opens in new tab) resolution (1920 x 1080).
There are various high-end laptops with 4K screens on the market. There are also several 4K resolution on the market now that are reasonably priced. However, if you want a 4K gaming monitor with a high refresh rate (120Hz or above), you’ll have to spend a premium.
