I've got a Dell system that came with a TNT card and a DVD decoder card for my DVD. My TNT card has approx. 16 pins on the card itself that accepts a ribbon cable from the decoder card. This allows me to see the image on my monitor that is going to my TV. This feature is a must for me since my Herc MX card did'nt have it and I couldn't stand it(my TV is in a diff room than my PC. Too many trips back and forth). I'm looking to update my vid card in my dell machine, so what is that feature called so I can make sure the one I order has it? My Herc card had holes where the pins would be but no pins.
