I am having the toughest time trying to figure out my dual monitoring problem. I have 2 Dell flatscreen monitors and am running an ATI 4850 video card with two DVI slots. I have all of the newest drivers for my video card. I installed RC1 today hoping that my dual monitor problem would go away, yet it is still giving me trouble. I have my main 23" monitor plugged in and when I plug my second 20" monitor in, both monitors flicker and then my main monitor locks up in a light blue screen with dark blue lines through it, then my second monitor is gray with black lines through it. When I take the second monitor back out, my main monitor brings my desktop back up, but its frozen and forces me to restart. I have been to the far reaches of the internet trying to find the solution to this but haven't had any luck. If anyone could give me any tips, that would be great. If you need anymore information about my system or anything, let me know. Thanks guys!
