I bought a DVI cable with RCA (Green, Red, blue) ends. I hooked the DVI port to my laptop, and plugged the RCA's into the TV (the TV has yellow, white, and red ports, but I heard they are interchangeable). I changed the input on the TV to AUX (which is what I use when playing videos games with an RCA cable) but the TV just stays black. I tried plugging the RCA cables into the different colors (as the colors don't match up obviously) and still nothing. Do I need to do something to the Laptop? Or am I just completely doing this wrong? Thanks for any help guys.
