Comparison of 4K Ultra HD and other common 16:9 aspect ratio monitor resolutions.

For a list of games, see List of games that support 4K Ultra HD.


Key points

4K Ultra HD (also 4K UHD or simply UHD) refers to a new standard of screen resolution at 3840 pixels wide and 2160 pixels tall.
It is important to note that 4K refers to the horizontal resolution, in contrast to others, such as '1080p', which refer to the vertical resolution. 4K Ultra HD is therefore also known as '2160p'.[1]

Properties

Advantages

Far higher resolution and pixel density leads to greater clarity and reduces the need for anti-aliasing.[2]

Disadvantages

Few games currently support 4K UHD natively.[3]
Running games at this resolution requires an extremely high-end rig - achieving 60 FPS at max settings on Metro 2033 requires four NVIDIA GTX Titans.[4]

Game support and fixes

Widescreen Gaming Forum (WSGF)

The WSGF have recently introduced a new set of medals relating to a game's support for 4K Ultra HD.
Similarly, the site also contains information on how to force individual games to support 4K Ultra HD.
This information has now been implemented into the PCGamingWiki video settings table.
The vast majority of games have yet to be rated by the WSGF for their 4K Ultra HD support.

PCGamingWiki icons

PCGamingWiki uses icons in the video settings table to illustrate the level of 4K UHD support awarded to a game by the WSGF.
