@vic20owner:
Are you using a scandoubler on your A1200, or does the monitor support 15kHz?
My LCD TV/Monitor has both VGA, SCART, S-video and Composite input, I'm using S-video right now (best available signal from a stock CD32). I guess the TV/Monitor maybe has some sort of flickerfixer on the TV bit.... don't know. All I know is that it won't accept 15kHz input on the VGA connector (complains about it being an 'unsupported mode') whereas Amiga RGB on the SCART works...
