Hi everyone,

Did the update to 12.8 tonight on my i5 2500k running 2x 6850s in Crossfire with a 27" Yamakasi in 2560x144ips and 24" Benq in 1920x1080.

System was working a treat for the past 2 months since I set it up, now after the update my system rebooted and now my monitors are not getting any signal.

Pretty stuck as now I get nothing.  No boot screens, no OS selection, nothing.  I have dual boot to Win 7 (default) and Win 8.  I know it's going through with the boot because the LCD on my keyboard boots fully.

Any clues?

If it was "working a treat" then why did you update the drivers? Go back to the ones that worked for you before.

try a different type cable like a vga and see if that gets you a screeen then roll back the update via windows. or if you have a video output on you mother board try that or swapp the displays. don't know if that will help but it might be worth a try.

oh yea , try the other card.

Thanks guys, I guess.

While a response like "why did you update your drivers" is about as useful as the proverbial tits on a bull, I appreciate you taking the time to provide me with a completely useless response.

I have managed to get a signal again.  After rebooting numerous times and switching between each card a couple time it finally worked.  Not sure why or what fixed it precisely, but it's going.

Sorry to anyone who comes here looking for an answer if you are experiencing the same issue.  I cannot tell you how I fixed it.
