HDMI to DisplayPort monitor?
An HDMI to DVI adapter would be more natural as the two connections carry the same video signals. Don't try to save $2 and get the wrong one. The one I linked to will work for all current HDMI to DVI connections.
UPDATE
DVI and HDMI carry the same signal, DisplayPort and HDMI do not. Every DVI connection can be passively converted (i.e. using an adapter, not a converter) to HDMI. DisplayPort can only be passively converted (i.e. using an adapter) to HDMI if the DisplayPort in question is designed for "dual mode", otherwise an active converter box will be needed.
