Monitorian is a Windows desktop tool to adjust the brightness of multiple monitors with ease.

(DPI: 200%)

The user can change the brightness of monitors, including external ones, either individually or in unison. For the system with an ambient light sensor, the adjusted brightness can be shown along with configured one.

In addition, the user can change the adjustable range of brightness for each monitor seamlessly.

  💾 Installer | 💾 Executables

When you use only executables, please note the following:

• The settings file will be created at: [system drive]\Users\[user name]\AppData\Local\Monitorian\
• When you check [Start on sign in], a registry value will be added to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

• The monitor name shown in main window can be changed for easier identification of monitors. To change the name, press and hold it until it turns to be editable.
• The number of monitors shown at a time is up to 4.

Add-on features are available for Microsoft Store version on a subscription basis.

The experimental command line interaction is available. For the usage, execute monitorian.exe /help. No path is necessary.

The code for add-on features is not included in this repository.

This app is a WPF app developed and tested with Surface Pro 4.

• You can check the compatibility of your monitor by probe.log. It will include raw information on monitors, including capabilities through DDC/CI, from various APIs that are used to find accessible monitors. To get this log, tap Probe into monitors in the hidden menu described below.
• To open the hidden menu, click app title at the top of menu window 3 times.

• As part of testing, you can manually trigger to rescan monitors via Rescan monitors in the hidden menu. A system sound will be played when completed.

• As part of testing, you can record operations to scan monitors and reflect their states. To enable the recording, check Make operation log in the hidden menu. After that, operation.log can be copied by Copy operation log.

• If anything unexpected happens, exception.log will be saved. It will be useful source of information when looking into an issue.

1. Install Visual Studio.
2. In Visual Studio Installer, go to the Individual components tab and make sure the following components are checked and installed. The version must match the corresponding field of project (.csproj) file of each project.

3. Load the solution by specifying /Source/Monitorian.sln. Then go to the solution explorer and right click the solution name and execute Restore NuGet Packages.

An alternative language can be shown by adding a Resources (.resx) file into /Source/Monitorian.Core/Properties folder. Each Resources file stores name/value pairs for a specific language and will be selected automatically depending on the user's environment.

• The file name must be in Resources.[language-culture].resx format.
• The name of a name/value pair must correspond to that in the default Resources.resx file to override it.

Resources.ja-JP.resx (for Japanese) would be a good example for this purpose.
