with my cable described here:
you have a multi purpose solution because it does not take into account
special features of some special graphics cards.
I never understood why people rely on things like on-chip composite
sync. You easily can do that externally by two Rs and one T.
I successfully use the VGA2SCART cable above for nVidia, ATI Radeon
and Intel graphics. Of course driver initializes separate sync for
