QD Oled Defringe

This app applies a screenwide filter that reduces the green/magenta fringe seen on samsung display qd oled panels. It works by using DLL injection on the desktop windows manager service; similar to how ReShade works for video games. Code is based on dwm_lut.

App Features

• Run in taskbar
• Filter strength adjustment (I like to run it at 0.5)
• Per monitor control: If you have a multi-monitor setup with only one qd oled display, set filter strength for other monitors to 0.0

Known Issues / Limitations

• Only tested on windows 11 with aw3423dwf monitor.
• Only works when monitor is operating in native resolution.
• Filter causes screen to become slightly blury. I believe this can be reduced with a more advanced filter but I dont want to spend time on this feature.
• May cause visual artifacts. For example on youtube, there may appear a thin green line under the video box.
• Does not work in fullscreen.
• Does not save settings. Will need to set settings after every launch.
• DirectFlip and MPO get force disabled. These features are designed to improve performance for some windowed applications like video players.

• May trigger antivirus.
