Overview
SIGNALIS renders at a fixed low base resolution (640x360, per a PCGamingWiki pixel-measurement note) with a genuinely fixed tank-controls/fixed-camera view, and PCGamingWiki lists ultrawidescreen support as 'hackable' rather than native. A Steam Community thread confirms that without a fix you just get pillarboxing (or a blurry built-in stretch option) rather than any extra world visible, so this is a real case where the base game shows no gameplay benefit from ultrawide; the BepInEx-based SignalisFix mod on GitHub is the actual community fix that adjusts the camera/UI for wider aspect ratios, but exact gameplay-benefit details of the mod itself (how much extra world it reveals) were not fully documented in its README, so confidence there is moderate rather than high.

Already have one of these? It works too
In-game Stretch display modeBuilt-in display-scaling option that stretches the fixed low-res render to fill ultrawide instead of pillarboxing it, at the cost of image clarity/aspect distortion - not a true widescreen fix.

Patch history & verification
current (2026-09-23)Sep 23, 2026
Verified via PCGamingWiki (ultrawidescreen=hackable, base render 640x360 per pixel-measurement note, fov=false), a Steam thread confirming stock pillarboxing/stretch-only behavior, and the SignalisFix GitHub README confirming it is a BepInEx plugin adding ultrawide support. Exact FOV/crop behavior of the fix itself is not fully documented, so rated fix-required/poor rather than good.
