I am runing a 30 in Dell Monitor ( 2600 x 1600 resolution) The image is not as sharp as it should be. I think it is running in analog mode.
How do i change it to Digital.
If it is connected to a DVI port on a graphics card then it is probably using digital. There isn't a specific way to switch. You might have a poor quality DVI cable. Did it come with the monitor? A quality dual link DVI cable is what you want.
