I just came across this forum. I bought this exact same TV on Black Friday of '08 as well. Well, I have Dish Network satellite, but now HD package for now and so obviously my TV says so. However I do have an Xbox 360 with HD output and when I switch it to the correct input on the TV for the Xbox 360 it says 1080p and the picture is AMAZING (also hooked up Xbox 360 without the HD cable and it was just normal resolution)! So the TV knows what is hooked up it seems. So, I guess just make sure that you have HD service from your cable or satellite provider and that you have the proper cables hooked up in the right places. That is all I can help for now.
