I'm new... Can someone explain receivers for me?

I don't think it is. 'Cause when I turn it on and put in a blu-ray movie the TV seems to automatically display it as 1080p, when it's a 720p TV. Also, I notice lip-sync when I do that.

I'm wondering if it's the HDMI cable. The performance of it that is. I mean, I'm simply talking HD quality, not necessarily picture quality, but they're basically the same thing. And I don't think it has anything to do with the lighting. It can be already dark and I don't feel the HD quality until later on that night near midnight or later actually, then it kicks in and it's awesome. I don't know why I can't get this all day long. People say there isn't any difference in HDMI cables, but I almost beg to differ, unless a receiver would be the solution. Is there anybody who knows what they're talking about in these boards?
