Monitor wake-up issue on Eyefinity-3 on HD7970 / MST-Hub, 3 out of 10 times

Postby Blín D'ñero » 26 Oct 2014, 13:35

The only real issue i am having in Eyefinity through MST-Hub (all DP) is:

After monitor wake-up call by moving the mouse , 3 out of 10 times, one (or two) monitor(s) stays black. I need to reset then (by unpowering/powering the MST-hub). Very annoying, because the result then is, that all (20 or more) windows i had open get resized to the exact same small dimensions and stacked on each other in the top left corner of the left monitor. And i have to unstack, resize and redistribute all of them again over the three screens where they were before, so i can continue working as usual.

It never happened when running all 3 monitors through DVI (and one DP/DVI adapter) on HD7970 and before on HD5870 crossfire.

I know the AMD driver team have a similar set-up as mine to test on, so they must have noticed and be working on to solve i guess.

It happens with 14.4 WHQL since i am using the MST-Hub. Also with Catalyst 14.9.1 and 14.9.2.

Next to this highly annoying issue, the whole screen seems to suffer a hiccup once in a while.

Both issues still exist in Cat 14.12... :shakes:

Update: the hiccup turned out to be a faulty videocard. It has been replaced.
