Hello,
For Someone (like me) is a problem, but for others, this can be a solution.
I have a “R7 240 LP” with CRT Emudrive ( https://cdcruze.com/2019/03/retroarch-and-crt-emudriver-setup-guide/ ) VGA port plugged to “UMSA Ultimate SCART adapter” plugged to " Sony Wega "
For Mame, Snes, SMS, SG, NES everything is perfect but for Dreamcast, PSX, Saturn, I have a sync problem ( Double Image ) , but if I plug a Monitor to the HDMI port and enable the Clone Mode ( Windows + P ) , the problem disappears, and everything is fine , even when I shutdown the monitor and the TV on
