Shaj Posted December 9, 2008 Share Posted December 9, 2008 Hi guys. Having a weird problem. Just got myself a new monitor (Samsung SyncMaster T220HD). It works fine through the VGA connector, but I'm having a weird problem when connecting it to DVI. The display is perfectly fine, but as soon as it wakes up from sleep I get a blue screen, followed by a glimpse of the desktop and then back to the blue screen. Since the monitor has multiple inputs, I tried connecting the vga cable as well. And this seems to have solved the problem. Now when it wakes up from sleep it shows the blue screen, followed by the glimpse of the desktop, back to blue screen and then finally everything back to normal. Anyone have a solution fot this? All the latest updates have been installed. XFX 8600GT 512MB card with VGA/DVI running via EFI strings with full QE/CI.

Thanks for replying. That is the exact method I used to get DVI working. Before that I couldn't even get any output through DVI. My problem is that the screen turns blue once the monitor wakes up from sleep and won't go back to normal unless the VGA is connected to the monitor as well. I have noticed a few other things though. 1) Through system profiler it seems as if my DVI is the secondary display connector and VGA first. However, with both connected, all the initial display (including POST and the Apple Logo) come through the VGA, but as soon as it boots to the desktop, the VGA becomes the 'secondary' monitor and the main screen shows up through DVI. 2) I get the blue screen when monitor wakes up from sleep. I get it when I switch from DVI to VGA on my monitor. I also get it when I switch off and on the monitor. On my Vista installation everything works perfectly. So not sure where and what the problem is. I am seriously considering NVKush or NVInject to see if it helps. Is there any difference between quality/performance over EFI?

Shaj Posted December 11, 2008 Author Share Posted December 11, 2008 Still no possible solutions One other thing I have noticed is that with DVI alone connected, the profiles and calibration make no difference whatsoever!
