- The resolution you entered isn't supported by your monitor
- Check Windows Display Settings for supported resolutions
- Try a standard resolution like 1920x1080, 1280x720, etc.
- Make sure the process name is correct (check Task Manager)
- If game uses a launcher, you may need to profile the launcher name
- Try adding the game profile again with correct process name
- Make sure Windows' explorer.exe is running (it's required)
- Try running as Administrator
- Check that .NET Framework 4.8 is installed
- Ensure you have write permissions to
%APPDATA%\AutoRes\ - Try running as Administrator
No manual configuration needed! Everything is managed through the GUI:
- Normal Resolution: Set via "Set Normal" button
- Game Profiles: Add/delete via "Save Game" and "Delete" buttons
- Preferences: Dark Mode and Auto-Start settings are saved automatically
Settings are automatically persisted to %APPDATA%\AutoRes\settings.xml (you never need to manually edit this file).
The app automatically filters these commonly-used processes to keep the list clean:
svchost, explorer, dwm, lsass, services, winlogon, csrss, wininit,
conhost, taskhostw, SearchIndexer, System, Registry, smss,
SearchProtocolHost, SettingSyncHost, WmiPrvSE, OneDrive, TeamViewer,
CCleaner, avast, avgnt, Avira, BitDefender, McAfee, Norton, kaspersky,
nod32, WindowsUpdates, TiWorker, ntoskrnl, Idle, chrome, edge, firefox, iexplore
Note: This is a heuristic filter that may be updated in future releases. If your game is being filtered out, check Task Manager for the actual process name and report it as an issue.
This keeps the process list focused on actual games and applications.
