Overview
Oxygen Not Included's side-view camera scrolls and zooms freely, so 21:9 and 32:9 both reveal more of the asteroid base without letterboxing or stretched UI, and menus/HUD render correctly at wide ratios. Confidence is slightly lower than a straight 'excellent' rating because PCGamingWiki flags its own ultrawidescreen and multimonitor notes as needing a citation ({{cn}} tags in the wiki source) and there is no WSGF dispatch for this title, so this is rated good rather than excellent pending a stronger independent source.

Patch history & verification
Current live Steam branchSep 21, 2026
Confirmed widescreen resolution=true and ultrawidescreen=true via PCGamingWiki infobox; could not confirm PCGamingWiki's own unreferenced ultrawidescreen implementation notes (marked citation-needed on the wiki itself) with an independent source such as WSGF, so overall_status kept at good rather than excellent.
