Hi I am looking at buying the following monitor: http://accessories.euro.dell.com/sna/productdetail.aspx?c=uk&l=en&s=dhs&cs=ukdhs1&sku=193757 It has a monster resolution of 2048 x 1152. Is it possible to connect this to my iMac? 2.4GHz 2GB RAM ATI Radeon HD 2400 XT graphics card. Will the Mini-DVI Out support this resolution? Thnaks.
