It's a medical prob. Ever since cataract surgery, I've not been able to tolerate any refresh between 60 and 85mhz. Many screens I can't tolerate at all, Sony in particular. I generally use LCD screens because they lessen the vertigo. It's hard to get 85mhz AND 32bit color. I'm not sure if my brand new monitor, not yet out of the box, will do 85 at true color, though I know it will do 85 at 16bit, that's why I got it. It's the largest LCD I could afford-- 17 inch. That's the equivalent of a 19 inch screen, biggest I've ever had. Maybe a better video card will help, but I don't know with LCD's if that will make a difference. I really don't want to go back to 60 or 65, it's hard to work at that refresh rate for very long. Painter won't work at ALL at 16 bit-- everything looks weird, posterized. I'd like to know if the same is true for Poser 5. The awful joke is I have a computer that can work at TrueColor without making me sick, but it's a non upgradable 450mhz processor, so SOL there. Emily
