I just got a 3 year old apple computer to use it to burn CDs and surf the web and even watch DVDs. I noticed a DVI output on the back and I connected it to the t.v. and saw the apple logo but nothing else after. I bought the cable for my Zenith DVB 318 and since it doesn't show anything due to HDCP, I kept the cable anyway. Do I need to a different DVI cable. I know that it comes in different letters like DVI-I, DVI-D something like that. can anyone help me to connect this computer to my Sony KP51WS520.
