I have a NEC PA271W 27" monitor which should get a resolution of 2560X1440 using DVI as I am using a KVM IoGear KVM GCS1204 switch. I have 3 other computers connected with DVI single-link to the switch that max out the resolution of my NEC monitor. I believe the cable between the KVM and NEC monitor is double link, but I am not sure if that even matters. I just puchased the SP3 docking station and am connecting with mini-display to DVI single-link connection to to my KVM switch. I am only getting a resolution of 1920x1080 which is a bit fuzzy. Do I need to buy a mini-display port to display port cable and plug the cable directly (by pass the KVM switch) into my NEC monitor to the the 2450 resolution I want?
