Hi guys, I'm looking at getting an external monitor to setup with my 13" MBP in my office come August. I've been looking at this Dell SP2309W: http://accessories.euro.dell.com/sna/productdetail.aspx?c=uk&l=en&s=dhs&cs=ukdhs1&sku=193757 as I've heard good things about it. I was planning on getting just a simple mini display to DVI adapter, however, on this thread (http://forums.macrumors.com/showthread.php?t=883264) someone mentioned that to drive a resolution higher than 1920x1200 you need a Dual-Link DVI adapter. The Dell monitor I was looking at supports up to 2048x1152, which does equal more pixels than 1920x1200 (2,304,000 vs. 2,359,296). So will I need Dual-Link? Also, if I did drive the display at full resolution how would that impact on performance, and is the 9400M even capable enough? If not, am I better sticking with a lower resolution monitor?
