I see the max resolution for an external display on this model is 2560 x 1600, and I'm looking to purchase a 27" monitor with 2560 x 1440 resolution. Connection on the monitor is Dual Link DVI. This laptop has the 9600M GT with 256MB. Would a Display Port to DVI-D cable run this monitor at 2560 x1440? Sorry for the n00b questions. Don't want to buy the wrong thing.
