Hello,

I have the problem, that often I get only a very dark red on all my displays. Only sometimes it is a very bright red. What could be the cause of this?

Thanks
Christian

Hey, best is to set the LUT to Always full refresh in the setting of the display. On automatic it will try to refresh fast but with the lost of color
