W540 - Dual Monitor Display Resolution with DVI-D Dual Link Cable
I have recently purchased a W540 and connected to my Dell u3011 30" monitor. I used the Dual Link DVI-D cable that came with the monitor and plugged it into my Ultra Dock. The maximum resolution i can get is 1920x1080? When i change over to a Display port cable i can achieve the full 2560 x 1600 resolution? Is there something i need to do in addition to achieve the full 2560x1600 resolution with the DVI-D dual link cable? I want to be able to connect 2 laptops to the one monitor and only have 1 display port input so i need to be able to use the DVI cable on the 2nd machine while still achieving 2560x1600 resolution.
