Baseline (Widescreen) Solution & Issues
Native anamorphic support. Graphics may be upscaled and/or letterboxed to any resolution, but are always rendered at 1280x720.
Run stasis_config_tool.exe from the install folder to access various upscaling options (particularly useful on older hardware).The best result is always a 16:9 picture, letterboxed in narrower aspects.
Ultra/Super-Wide (21:9/32:9) Specific Solution & Issues
Native pillarboxed support.
Eyefinity / Surround Specific Solution & Issues
Pillarboxing = no support.
If your center monitor is narrower than 16:9, the pillarboxed picture will be cut-off by bezel gaps. Run stasis_config_tool.exe and select preset 'Forced for non-standard screens' to manually input your single-screen resolution. The game will run letterboxed on the center screen.
4k UHD Specific Solution & Issues
Upscaling: 720p stretched to fit the screen.
