I have a HP Pavilion Elite HPE-250f with a special HP version of the AMD HD5770. HP specs say the DVI is Single-Link. However, the board contains 2 DVI-I connectors suggesting that it is Dual-Linked. I want to buy a 2560x1440 monitor but it requires a Dual-Linked DVI. Can anyone confirm that the HP version is indead SIngle-Link? Thanks.
