: Contains resolution settings and panel voltage requirements.
Knowing the controller board model number (printed on the green PCB) would help identify exactly what this file does.
In the world of display hardware, "AVTER" typically refers to or specific firmware variants for universal controller boards. If you extract this .rar file, you will likely find: A .bin file : This is the actual firmware image.
The file appears to be a specific compressed archive commonly associated with firmware or driver updates for specialized electronics , specifically related to LCD/LED controller boards or TV mainboards (often the SKR or TP.VST series).
