Dual Monitor 5850 Screen Flickering

post #1 of 3
Thread Starter 
Ok, so I have a 5850 and dual monitors. On the second screen there is a constant flickering or tearing in the picture. When I had Win7 I had a fix using afterburner but now in Win8 it does not work. What can I do?

The computer is running Windows 8 on 2 1920x1080 screens not in eyefinity on a single 5850.

Your sig says 5830!?
Anyway, had this on my 5770.
Fixed it by moving the monitor with the flickering off of the DVI port it was on and onto the HDMI port, via a HDMI to DVI cable.
I've had no probs since. Hope I helped!

All 5xxx series cards have this problem. If you have your card overclocked that is what is causing the issue. The 2d clocks are the issue.

Setting to stock eliminates the issue or if you want the card overclocked 24/7 then you need o edit the profiles and have 2d clocks set to 400mhz.

When you overclock 5xxx series cards the 2d clocks go down to 157mhz and cause the flickering issue.
