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]
- Modern graphics cards are finally powerful enough to achieve 4k resolution at smooth frame rates. A single GTX 1080 Ti can play many modern games at 4k at 60 fps on ultra/maximum settings, and can even achieve 120+ fps on most older titles up to about 2012. [3]
Disadvantages
- Some games do not support 4K UHD natively.[4]
- Running games at this resolution requires a high-end rig - in 2013, achieving 60 FPS at max settings on Metro 2033 required four NVIDIA GTX Titans.[5]
- Mainstream 4k displays are currently limited to a 60 hz refresh rate. 4k monitors with a high 144 hz refresh rate are scheduled to be released in the near future, but the initial retail price is expected to be extremely high (likely a few thousand dollars). [6]
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.
Gold | Silver | Limited | Unsupported | Incomplete/Unknown | |

Description |
Equivalent to an A-grade from the WSGF. The game has received a perfect score from the WSGF for its 4K UHD support, and is '4K Ultra HD Certified'. | Equivalent to a B-grade from the WSGF. The game is without major flaws in its 4K UHD support, but has at least one blemish that prevents a perfect score. | Equivalent to a C-grade from the WSGF. The game has some level of 4K UHD support but has significant practical issues. | Equivalent to an unsupported grade from the WSGF. The game is unplayable in 4K UHD, or the image may be stretched to fit the window. | Equivalent to an incomplete or unknown grade from the WSGF. Analysis of the game's 4K UHD support has not yet been completed. |
Linux support
4K support on Linux, especially at 60 Hz, can be spotty due to the varying quality of drivers and their ability to stitch together DisplayPort MST panels. hax11 attempts to work around similar issues by intercepting and editing X11 requests between games and the X server.
