[quote]I am also having an issue after updating to the 10.4 drivers. My DisplayPort monitor just turns off after a while. I have to disconnect the video cable and plug it back in to get it to work. I am going to revert back to 10.3b.
Same (sort of) problem here. After correctly uninstalling 10.3b, running driver cleaner, and installing 10.4 i got blinking issues on my mini DP - DVI connected display.. never had them before with 10.1, 10.2, 10.3 and the forementioned 10.3b.
Did have them before with my Apple DP-DVI active adapter and DP-VGA passive, but bought the ACCEL mini-DP DVI active one, works like a charm..
Reverted back to 10.3b -> problems gone!
Shame, 10.4 had the 2D acceleration right, very noticable in DIRT 2 Intro.. Everything went very speedy. Back to choppy video's then..
Is this a specific driver problem?? Or should i flash the 5970 bios for more DP voltage?? (rather not)..
From what I can see it is driver related. I did not have these problems with previous drivers. To bad we can't get word around here from Dave. Be nice to know if they are aware of the issue and or going to release a hotfix.
