xfx 5770 on Dell 3008 LCD issue

[amenlo9]

Hi all, i am using xfx ATI5770 with my Dell 3008 with 2560x1600 resolution. I am facing annoying issue which every time after the apple logo finished loaded (before desktop appear) my LCD will become power saving mode and become blank. I need to unplug the DVI cable and reconnect back the cable in order to see the screen again. Then i dual booted into Windows 7 but screen never become blank. Tested with another samsung 23 inch LCD and found that no issue on the Lion. Any idea how to fix this issue? thanks

got my problem solved by using the Display port instead of dual link DVI.
