I have the same TV and Direct tv hooked up via hmdi. It should be on video 6 or 7. I use one for Direct TV and the other HDMI (video 7) for my DVD. Other than plugging it in correctly and then scrolling to video 6 or 7, nothing else you should need to do.
I just bought this tv yesterday(a return) and the hdmi doesn't get recognized by tv. Does anybody know if I am doing something wrong??????? I'am plugging into dishnetwork hd receiver then into tv. I have 2 hdtvs the other works fine thru hdmi??????
