My daughter's boyfriend bought a new Samsung LCD, not sure the model but it's a good one with the 240Hz and all the latest features, except 3D. He is having a problem getting 1080i from cable box. He is using HDMI connection and the set will show he is getting 720p but that's it. According to my daughter they already checked the settings on the cable box and TV. I need to find out what happens with Blu-ray and will post back. Any other ideas what could be wrong? I also need to get over and see what that thing looks like.
