This is strange. I've got the PowerMac G4 cube, hooked up to one of my Sun 21"s via a HD15 cable. One monitor, 1600x1200 at 85Hz works fine. The other, "OUT OF SCAN RANGE" Weird. Apparently Sony "upgraded" the internals along the way... The monitors look IDENTICAL. bill -- Bill Bradford mrbill at mrbill.net Austin, TX
