01
Choose the display scope.
Use All Displays for a simple setup, or target one monitor when only that screen should change.
App rules
Set brightness automatically for each app.
Create app-based or fullscreen rules so Display Dimmer changes brightness when your work app, browser, game, or media window is active.
02
Add an app or fullscreen trigger.
Click Add rule, then browse for the app's real .exe, drag in an executable or shortcut, or use fullscreen detection.
03
Set the brightness and click Apply.
Choose the brightness level, turn the rule on, and click Apply. Display Dimmer will use it when that app is active.
Find the real app
Use the real app executable for best results.
Some apps open through shortcuts, launchers, browser helpers, or Store wrappers. App rules work best when the rule points to the executable Windows is actually running.
A
Open Task Manager.Find the running app under Processes.
B
Open file location.Right-click the app and choose Open file location.
C
Select the .exe.Browse to that file in Display Dimmer, or copy its path.
Shortcuts and file types
Use file types that identify the running app.
Using the correct file helps ensure rules trigger reliably when your app is active.
Use .exe files
Pick the real app or game executable, such as chrome.exe. This gives Display Dimmer the clearest match.
Shortcuts can work, but .exe files are better
A Windows shortcut can work if it points directly to a real executable. If it opens a launcher, URL, or helper app, use Task Manager to find the real .exe.
Avoid web shortcuts
Internet shortcuts and launcher-only shortcuts do not reliably identify the running app that should trigger the rule.
Click Apply
If the page says changes are not applied yet, click Apply before closing Display Dimmer.
When multiple rules match
Display Dimmer checks foreground app rules first, then fullscreen rules, then running-process rules. More specific display scopes win over All Displays; ties use the saved rule order.
When the app stops matching
The app rule releases the display. If a schedule is active, the schedule takes over; otherwise Display Dimmer restores the brightness saved before the rule applied.
Fullscreen rules
Set brightness when apps go fullscreen.
Display Dimmer can watch for fullscreen games, video, and presentations, then apply the brightness level you choose. This helps when different apps go fullscreen, or when a game or video player is hard to match by executable.
