Here’s my settings yours could be different
Brightness Iam at 75
Contrast 25
Scroll speed (very important)Iam at fast at 3.5mphto 4mph ,1.5 mph Iam at slow or medium you will have to play with that .
Interference low
tvg low
both of the last one can be played with depending on the trash floating.
in real life the screen looks a lot better than snapping a pic with the phone I have saved them to my memory card and I will play with that later.
