[QUOTE="Avalon, post: 242584, member: 5184"] Hi urbankato. I checked at Apples service source, and there is no compatibility issue between your screen and your card. And if it works in Safe Mode, it seems to me that the screen resolution seems to be wrong when booting normally. Did you try reseting the PRAM (startup, press and hold apple+alt+P+R until you heard the startup chime 3 times)? What you can also try is getting into Open Firmware mode (hold apple+alt+O+F while starting up). Once there (grey background with black text) type the following, each followed by a return: reset-nvram set-defaults reset-all Sometimes when there are messed up values there, the screen doesn't get correctly recognised. Not sure if it'll help, but worth a try. [/QUOTE]
