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.

(DPI: 100%)

• Windows 7 or newer
• .NET Framework 4.7.2
• An external monitor must be DDC/CI enabled.

• Windows 10 Anniversary Update (1607) or newer:
  Monitorian (Microsoft Store)

• Other:
  💾 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 code for add-on features is not included in this repository.

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

The logs will be useful when looking into an issue.

• exception.log - Information on exceptions when an unexpected problem happened.

• probe.log - Information on capabilities of each monitor obtained from various APIs and used to find accessible monitors. To get this log, click the app title in menu window 3 times and then tap the button appeared beneath.

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 right click the solution name in solution explorer and execute Restore NuGet Packages.

An alternative language can be shown by adding a Resources (.resx) file which stores name/value pairs under /Source/Monitorian.Core/Properties folder. The system will automatically select the file which matches 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.
