Have you tried turning on the monitor for a few seconds before you turn on the system? Perhaps the monitor has to "warm up" in order to synchronize with the card.

This would also tell the board to enable the color D/A chip and tells it that the monitor can (probably) handle VGA sync specs. I imagine that ATI uses it also on the OEM board in my Gateway2000 at work. I have to have the MultiSync 3D monitor powered up when turning on the machine before turning on the computer. As a rule, the monitor shouldn't need to be warmed up (how is the computer gonna know B-). I don't have an outlet strip. ----- "Lets go kick some Earthling butt!" -- Spaced Invaders quintro!bpdsun1!rmf@lll-winken.llnl.gov uunet!tiamat!quintro!bpdsun1!rmf
