2nd Monitor Flickering Using 10.3 Drivers

Hi all, I was wondering if anyone could help me or if anyone had had these problems before?

I just upgraded to 10.3 and I am finding that my 2nd monitor is flickering, the 1st/main display is fine.

Should I go back to 10.2? Or is there a simple workaround that I'm not aware of?

Many thanks for any help offered.

Disabling ATI Overdrive seemed to stop it flickering, could my settings have been too high? I am only using the ones that it gave me when I used auto-tune.

I get flickering when ever I use overclocking on the second display. I only tested what the card could overclock to so don't overclock in normal use.

when I did it I noticed the 2d clocks were droping from 400gpu 900 mem(iirc) to 157gpu 900 mem (again iirc) and that with 2 monitors is too low - and then the flickering started.

Not sure what the problem is but it's definately powerplay related.
 
Yep.. I too have this. Powerplay is buggy and doesn't work well with two or more screens if you overclock.

solution - don't overclock if you want to use dual screens. It really does suck, and no drivers are fixing this issue. My 5870 is awful with dual screens if I overlcock by just 1mhz.!!

I just run mine at stock, seems to stop this. Typical ATI fair really... Top notch performance, poor drivers (at times) which is a shame, as it really does take away from an otherwise excellent performing product..
 
You could try this solution, as it stopped problems i had with multi monitors and also getting 120hz monitor working properly.

- Create a new profile in CCC, but dont activate it.
- Search for the name of the profile, it will be an XML file in your windows/users folder.
- Edit the xml and increase the 2d clocks. (shown in picture)

- I had to increase my 2D core to 600 and the memory to full 1200 to stop all flickering and get 120hz working properly. But you can try the numbers shown in the screen shot. Keep increasing them till the problem stops.
- Once you have edited the xml, save and load up the profile.

Worth a shot it sorted all my ATI problems.
