i have the following issues:
The brightness of my PC is changing on random occasions. Normally a few minutes after I start the PC the brightness gets dimmed. but then a few minutes or even hours later it gets brighter again and the whole cyrcle begins from the beginning.
adaptive brightness in Windows and in the TV settings is already set to off. Also automatic adjustments of contrast has been set to off.
Hope i find a solution here after searching the web for more than one day.
