About 2 months ago i picked up a XFX HD 6870 BE. I have been having some issues with picture on the displays.
I have three 22 wide Acer's all in a row. The left and center are on the DVI ports and the right is on the mini display port. I have got the adapter for the mini display to DVI Link
When I got the card did a clean install of Win 7 64bit Ultimate and updated all drivers. I have since uninstalled and reinstalled the video card drivers with no change to the issues.
The card is not overclocked and is running stock. and now to the issues..
When running eyefinity some times the right screen will go black and get no signal, if I unplug the monitor and plug it back in the picture will come back.
This does not happen when it is not in eyefinity. There is also a slow rolling horizontal invisible line some times again only in eyefinity mode rolling goes from bottom to top.
The center screen has a static invisible line (horizontal) in the center of the screen and is only seen when there is movement on the screen. Again only in eyefinity mode.
and the last issue is when running a game (EVE) there are models that will blink like there is a strobe light on it. This happens in and out of eyefinity.
I used to have a 9800gtx and 9600 gt running these 3 monitor's and didn't have any of these issues up until I changed out the video card.
If any body has any ideas it would be greatly appreciated
