Radeon RX Vega M random dimming

Hi,

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 cycle begins from the start..

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.

Hello soundofmaggots,

 

 

Thank you for joining this Intel Community.

 

 

The latest Radeon™ RX Vega M Graphics Driver for this Intel® NUC is 18.9.1. Are you using a Beta driver? If so, does this issue happen if you use the drivers validated for Intel® NUC Kit NUC8i7HVK?
