Thanks for you answer.
Its a desktop computer.
Motherboard: http://www.gigabyte.com/products/product-page.aspx?pid=2758
I think i will have to buy a HD5670 al least :(
Bought this monitor yesterday :)
Now i have a problem....
U2711 + HD3200
DVI Cable from Dell (supposed to be Dual Link).
When I set 2560x1440 the OSD Menu shows 1280x1440 and all is very blurry. I cant see anything.
Any ideas?
