I hope someone can help here. I have a Yamaha receiver that is HDMI compatible (rxv563). I connected the hdmi from the input from the tv to the output of the receiver and then I connected an hdmi cable from the cable box to another input of the receiver. The problem I am having is the cable box is setting to a default setting of 720p. I mannualy changed the settings from the cable box from 720p to 1080i. when i turn off the receiver, tv and cable or even if I leave the cable box on. when I turn on the tv and receiver the cable box defaults to 720p again. Yamaha is saying their is nothing to trouble shoot. Funny thing is that when I run the hdmi cable from the cable box to the tv and a optical cable from the cable box to the receiver the cable stays at 1080i. if I do that, then I am not getting anything out of the receiver? Can anyone help?
Is there any perceivable difference in the picture you're seeing between 720p and 1080i? Generally, the two are equivalent, one is not better than the other, it's more of compatability thing. If it's switching back to 720p and you don't see any difference, there probably isn't, so don't worry too much.
I wouldn't worry too much about watching TV in 1080i vs. 720p. Probably not much difference to seen anyway, seeing as how most cable signals are crap anyway. If I'm watching a movie on my Blu-ray it's a different story altogether.
Dave, if you're watching your Blu-ray in 1080i or 720p you're losing out. That would be 1080p for Blu-ray - right? I agree, though, no worries between 720p and 1080i, especially when it comes to cable - even if it's HD programming.
My brothers got the Sony XBR which has 1080p and the 24fps and that is jaw dropping on Blu-ray - so no one needs to sell me - it's just a matter of time for me.
