WARNING: this monitor will not work with DisplayPort.
15 April 2009
Summary: As several others have pointed out, you need a dual-link DVI port to drive this monitor and then only in its native 2560x1600 mode. It will not work with DisplayPort-to-DVI adaptors because they only support single-link DVI. If you use one of these adaptors, the monitor will display at 1280x800.
