I have a Samsung LN40A650 TV and just purchased a Samsung Blu Ray player and it doesn't display a 1080p picture via HDMI. It displays a 1080i picture via component cables. I also have an upconverting Denon 790 receiver and my TV display glitches at 1080p when using HDMI. I change the output display to 1080i and it is fine via HDMI. I contacted Samsung to see if there was a firmware update that addresses this issue but there wasn't. Does anyone have any ideas? Please help. My warranty has just expired.
