Prüfen ob der Bildschirm richtig angesteuert wird

Es ist wichtig das euer LCD Bildschirm mit 50 Hz angesteuert wird. Es kann folgendermaßen geprüft werden:

vdruser@vdr:~$ DISPLAY=:0 nvidia-settings --query RefreshRate

Attribute 'RefreshRate' (vdr:0.0; display device: DFP-1): 50,00 Hz.
'RefreshRate' is an integer attribute.
'RefreshRate' is a read-only attribute.
'RefreshRate' is display device specific.
'RefreshRate' can use the following target types: X Screen, GPU.
