DVI/VGA port on monitor
Hi, i just bought a new Benq20inch wide screen. It comes with both DVI/VGA port and cables. I also have a dual port video card.
But i'm a bit confused at the use of plugging them both in at once. There is a switch on my monitor which switches between port 1(dvi) and port2(vga) inputs, so theoretically i can have a extended desktop. But realistically, is there actually any more practical use of plugging both ports in at once? bit confused at how the inputport switch would be used.
any help thanks~~!!
