Dear All,
finally I got my Setup on a Raspi 4 running with Hyperion. Quite Smothly. But the left part of the frame, does not apear to be recognised by the videograbber. When I check the live view in the Hyperion Web frontend it is blurry ( See attached screenshot) and it does not grab any colors or changes in the picture.... 
Is there a possible fix for this problem ?
Thanks for an help!
