Hi all,
Today, after resuming of the notebook from a sleep state I had a screen blink and it does again the same. Whenever I try to do any setup to the video, it is applied but after aprox. 3 seconds the settings is reset again to the default so I am unable to change anything in the display settings again.
I am also still waiting for the response from DELL support.
If you have any further ideas, i would appreciate them very much.
