Key points

Ultra-widescreen is a term applied to widescreen resolutions that apply a 64:27 (marketed as 21:9) aspect ratio;[1] in contrast to the more widely supported 16:9.
The most common resolution supported is 2560x1080.[2]

Allows to see more of the game world at once.
Removes letterboxing from the top and bottom of the screen while watching films and cutscenes in certain games.
Ability to split the screen into two or four segments while working.[3]
For games that give a zoomed in (Vert-) image, if FOV is adjustable it can be adjusted to compensate and give a proper Hor+ true ultrawide image. The Wide Screen Gaming Forum FOV Calculator can be used to calculate the proper FOV increase to achieve a proper 1:1 Hor+ image (in general, when going from a 16:9 to 21:9 image, a horizontal FOV increase of 17 will convert a Vert- image to a proper Hor+ image).
If a game does not properly support ultra-widescreen resolutions, on most ultra-widescreen monitors the game can often still be played in a pillarboxed 16:9 or 4:3 resolution. This may involve using GPU scaling in the GPU driver settings to prevent stretching to fit the screen, and in some cases using a custom resolution.

Aspect ratio not recognized by storage and transmission standards.[5]
Many games, especially older or lower budget titles, either do not support ultrawide resolutions, use Vert- to zoom in on a standard 4:3 or 16:9 image to fill the screen, or simply stretch a 4:3 or 16:9 image to fit the screen instead of giving a true ultrawide image.
Unlike Vert- games, if the game simply stretches a non-ultrawide image, FOV can be adjusted to create a wider image and approximate Hor+ but the proportions will still be somewhat off.
For Vert- games in which FOV cannot be adjusted, at ultra-widescreen resolutions the FOV may be so zoomed in that it seriously impacts gameplay.

Game support and fixes[edit]

Widescreen Gaming Forum (WSGF)[edit]

The WSGF have recently introduced a new set of medals relating to a game's support for the ultra-widescreen 21:9 aspect ratio.
Similarly, the site also contains information on how to force individual games to support the ratio.
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 ultra-widescreen support.

PCGamingWiki icons[edit]

PCGamingWiki uses icons in the video settings table to illustrate the level of ultra-widescreen support awarded to a game by the WSGF.
