Baseline (Widescreen) Solution & Issues
The game treats 16:10 resolutions inconsistently. 1024x640, 1280x800, 1440x900 and 1680x1050 are hor- compared to 16:9, while 1920x1200 and 2560x1600 are letterboxed.
Ultra/Super-Wide (21:9/32:9) Specific Solution & Issues
The game is pillarboxed by default. Rose's mod removes the black bars but also introduces a softlock-like issue affecting three scenes. The mod description includes the available workarounds.
Eyefinity / Surround Specific Solution & Issues
Same issues and solution as for ultra-wide. The HUD is minimal to nonexistent, however, there are instances where the non-crucial elements appear on the side screens, as well as instances of closely inspecting objects resulting in them being partially on the side screens. The loading and auto-save icons appear on the sides as well.
4k UHD Specific Solution & Issues
The game supports 3840x2160 but introduces pillarboxing at 4096x2160.
