Widescreen resolution

The game is always letterboxed to 16:9 resolutions. Aspect ratio is hackable by replacing 39 8E E3 3F in Limbo.exe with the desired aspect ratio value according to here.

The game always uses the desktop's resolution, but by default, it uses a 1280x720 rendering resolution. It's possible to force a higher rendering resolution, but the game intentionally uses blurring and other image filtering methods combined with assets made for 720p resolution, so the impact on graphical quality is negligible.

Change the game resolution using the configuration file^{[citation needed]}
Go to the configuration file(s) location. Open `settings.txt`. Find and change `backbufferheight = 720` to the desired vertical resolution.

Windowed

Switch to windowed mode using the configuration file^{[citation needed]}
Go to the configuration file(s) location. Open `settings.txt`. Change the line `windowedmode = false` to `windowedmode = true`.

Borderless fullscreen windowed

Force borderless fullscreen^{[citation needed]}

Install Special K by following the Special K Unofficial Guide. Manual local installation may work better.
Start the game and press Ctrl+⇧ Shift+← Backspace to toggle Special K's Control Panel.
Open the Display menu and select "Windowed Mode" and "Force Override".

Issues fixed

Run the game at screen refresh rate

The game by default uses Vsync (Always on) and also forces the monitor refresh rate to 60 Hz, which results in a limit of 60 FPS.

Fullscreen mode defaults to 60 Hz, even if the screen refresh rate is set higher than that.

Set screen refresh rate^{[citation needed]}

Install Special K by following the Special K Unofficial Guide. Manual local installation may work better.
Start the game once and close it immediately to allow the Special K configuration file to be created.
Open <path-to-game>\d3d9.ini or %USERPROFILE%\Documents\My Mods\SpecialK\Profiles\limbo.exe\SpecialK.ini depending on the installation method you used.
Change RefreshRate=-1 to RefreshRate=0 under [Render.FrameRate].
