I currently run my PC with two screens which I find very useful. I propose to change my PC for a more up to date model which has a DVI output and and analogue output from the video card. I intend to use the primary screen from the DVI output of the PC (for better picture quality) and the secondary screen from the analogue output. A local PC supplier says that I cannot do this since the digital signal and the analogue cannot be used in tandem. Any thoughts on how I can use 2 screens in DVI and analogue?
