Overview
Brotato does not support ultrawide natively: PCGamingWiki lists ultrawidescreen=false and the resolution is effectively locked (4k also false, noted as locked to 1080p-equivalent), so 21:9 and 32:9 displays are pillarboxed by default. A Steam Workshop mod ("Multi Res - Ultrawide") lets players expand the width and remove black bars, though community reports note the map/arena is a fixed small square, so revealing more width mainly shows more of the arena border rather than meaningfully more gameplay space, and at very wide 32:9 ratios black bars may return. We could not independently verify the mod against the exact current build, so we could not confirm it as fully reliable, and safety is unknown.

Confirmed native pillarboxing via PCGamingWiki Video infobox (ultrawidescreen=false) and confirmed a Steam Workshop mod addressing this exists via Steam Community search; could not verify the mod's current-patch compatibility firsthand, so recommended_fix compatible_patch is marked as community-reported only and online_fix_safety kept as unknown.
