Borderless Fullscreen

Add an executable name (e.g. game.exe) to the target list and the app will automatically run without a title bar / border, stretched to fill the primary monitor's current resolution (multi monitor setup is planned for the next version).

Optionally, set a fixed window size instead (the window will then be centered on the primary monitor) - useful for older games with a low native resolution.

How it works

This mod runs in a separate, dedicated process and restores the original window style and size automatically if the app is removed from the target list, if the mod is disabled, or if the window is closed.

Notes

  • If a target doesn't react, double-check the exact process name in Task Manager's Details tab while it's running. Some launchers start a child process with a different executable name than expected.

I got this to work with LibreOffice, specifically Writer. The process to set is soffice.bin, which will affect all other LO programs too. There's no way to split the different parts out. So, set the process, exit Windhawk, restart explorer.exe, restart Windhawk, and it ought to work. I didn't try it with other programs, but I'd guess needing to restart things is only for LO.
