My main monitor is a 15 inch LCD TV Monitor. The quality is excellent but it sometimes has trouble syncing properly to Amiga composite displays. It has no problems with a scan doubled Amiga signal in the VGA input. I also have a 7 inch portable DVD player with composite video in and it syncs perfectly to an Amiga composite display but the screen size and display quality are not that good. You might look for an external genlock that has a S-Video out. This would give you much a better quality display than using composite video.
