just crossfired my pc

[kiel367]

just recieved my second 5770 from the bay
install went fine
latest ccc
but
now i cannot get the resolution to be fullscreen on my display
i am using vga to a hanns-g hw73a 17inch
i previously had it spot on with 1 card at 1360x768 32bit in the advanced setting under windows screen resolution as i cannot get ccc to give me the correct display, it sometimes jumps to it, but my screen decides to auto adjust as it doesnt seem to like the resolution, the only full screen i can get is 1024x786, this was the issue i was having even before i got the graphics card but i seemed to resolve it with the manual selection of the resolution, now i try it again and im left with rubbish resolution and black lines round my screen, can anyone help?

Wasn't one card enough for such a low res?

 

[kiel367]

well thats hardly the point, i could do with a solution really

 

[arc@css]

True, though it is a good point nonetheless. Sorry to hear of your problem, there's a few cf 5770 owners that'll most likely pop along later. Good luck.

I had a similar issue when i first crossfired my 4870's. turned out to be because of RAM size being different on the two cards (indavertadly ordered a 1GB version... oops)

The black lines went away for me when i changed one of the GPU's but i could only change the res on the desktop through windows

Could be a RAM size issue is my point if they are different

the cards are identicle cards matey

whats the max resolution support combined with its max supported refresh rate on your monitor?
whats the catalyst version number that you are using.
in cc properties what is it showing for your display settings?

its ok i sorted it, i managed to get it to 1440x900 and mess with the inbuild monitor centering built into my monitor, thanks anyway folks!

ok sounds like the refresh rate and resolution was out of tolerance
