DJ_GLiTCH Tip: Auto-switch resolution per game (May 6, 2025)
The code is stored in Launchbox emulator settings, under "Running Script" for Teknoparrot.
You'll need QRes.exe to make this work too (download link below). No install required, just copy QRes.exe into a folder you'd like to save it in.
Change the directory path in the code to suit where you have saved QRes.exe
Note: 1: The resolution and refresh rates are tailored to my monitor (4k 240hz). If you have a different refresh rate you want to use across all resolutions, change /r:240 to be what you need (240 = 240hz, 120 = 120hz, 60 = 60hz, etc.). The resolution is self-explanatory, and is in the ChangeResolution(x,y) loop section.
Note 2: I've only populated Luigi's Mansion so far but will add more games later, and will try to make the original resolution and hz more smart (currently I hard code 4k 240hz).
Note 3: If you have any issues, try setting your display scaling to 100%.
- Persistent
- Function to change the resolution
ChangeResolution(width, height) {
RunWait, "C:\xxx\QRes.exe" /x:%width% /y:%height% /c:32 /r:240,,Hide
}
- Run when Luigi's Mansion starts
Loop {
Process, Wait, VACUUM.exe ChangeResolution(1920, 1080) ; Change to the desired new resolution for the game Process, WaitClose, VACUUM.exe ChangeResolution(3840, 2160) ; Restore the original resolution for the monitor}
