I just purchased a mid 2010 Mac Pro with a ATI Radeon HD 5770 video card. It arrives later this week. I'm looking to purchase a monitor but it's not clear to me what resolution monitor is needed. I know the card supports 2560 X 1600, but I'm wondering if it will support a lower resolution monitor such as 2560 X 1440. Any help would be appreciated. The selection of 2560 X 1440 monitors is much greater so I'd like to chose one of those if it is compatible.
