3 x Akasa SATA-2 45cm Silver Data Cable

1 x BenQ G2420HDBL 24" Widescreen LED Monitor

1 x Windows 7 Premium 64bit

Thought I’d provide that, so as you know what I’ve got and maybe point me in the right direction…

If I turn on multiple displays, one being the BenQ 24” LCD at 1920 x 1080 res, and I also plug in a spare 42” plasma panel at 1280 x 720 if I run something like VLC media player and move the video playback to the second display, this being the plasma screen, the LCD display goes all funny at the bottom half, square blotches, lines across the screen, flickers and if I turn off multiple display support it goes away.

This doesn’t happen in the BIOS, both displays are rock solid, doesn’t happen if I put a video via VLC or XBMC on the Plasma and then run a game in 1920 x 1080 on the LCD, its only with the windows desktop..!! I’m at a loss, looked at the temps etc… powerplay is working, card is ramping up and down when needed, average desktop temps are around 24 degrees, using furmark not a stutter, display is rock steady, temps no higher then 72 degrees after running furmark 3D for 20mins burn test..

Only happens when I run two displays and move video or something to the second screen…..using CATS 10.2, haven’t tired the 10.3 beta yet….

Any ideas? Maybe using two different desktop resolutions isn’t good idea…. Sadly the spare 42” plasma I’ve got can only handle 1280 x 720…..

Thanks… BTW using DVI for both displays. Plasma using a DVI – HDMI cable.

I’ve been trying to think when this happened, I do suspect Batman Arkham as it installed Nvidea Phys-X even though I can’t use it….

Driver issue, or something not compatible, I thought furmark 3D would tell me if it was the card, and that shows no corruption what so ever, neither does futuremark 2006… Haven’t tried vantage yet..
 
It is a bug in powerplay when using dual screens. I set my pci-e lanes to 101Mhz in the bios and it fixed it for me(but not working for everyone). Or you can try to switch powerplay off.
 
Ah…. Didn’t think to google powerplay bug. Soon as I typed that into google I got lots of results with the same symptoms as me…

Half the screen on the first display flickers – just as I’m getting. Apparently AMD are looking to try and fix this, TBH I can live with it. .. I don’t use the second display as a desktop display. Its only for watching blu ray, HD MKV files and some gaming… I can enable and disable the screen as needed.

I’m just happy its not the card borked..!!
