Hi guys,
I'm having a problem with my graphic card. I just switched from 9800 gigabyte to Sapphire 5770. I updated the os to 10.6.8... with the 9800... booted fine.. then switched the graphic cards and I got a black screen right after the apple logo... so after couple of try and errors... I connected the dvi cable to a 24" running at HD res and it booted fine.. so then I connected it to the 30" just switching cables and it worked fine again... but when I restarted it... and let it run just with the apple 30" I got the damn black screen again.. but when I reconnect the DVI... it gets out of the black screen with full resolution... so anytime I restart the computer I gotta plug in and out to get the 30" working... also I used HDMI - DVI cable for the 24" and it didn't recognize the 2nd screen either... do you guys know what I'm doing wrong?
Any help would be amazing...
Thanks so much
PS. system profiler recognizes the card as 5700 series...
PLEASE HELP
