A friend just gave me an ACD (I'm not sure of the size, I believe it is 23", 1920x1200,which looks like a 2002-2004 vintage. I think I need a $125 cable to connect the ADC to a DVI adapter. My inclination is to just dump it, is there any reason I should keep it? It doesn't seem like it's worth the cost of the cable, better to put that towards a new display. Thoughts?
