VGA uses separate H- and V- sync pins. Suns sometimes use composite
sync on a single pin, and sometimes sync-on-green, with no sync pins.
Those passive adapters are primarily for sync-on-green. Most* PC
monitors are just fine with sync-on-green signals, but they're confused
by the garbage/noise coming in on their H- and V- sync pins. Simple
solution: clip the sync pins out of the VGA cable you use for your
* Nearly all LCDs will accept unusual analog signals, with varying
degrees of good/bad behaviour. I once had a $100 HP monitor that would
display SoG perfectly, then overlay a "NO SYNC" error message on top of it.
