I would imagine this would be an issue for all cable boxes, But my Comcast HD box only does 1080i, I havn't heard of a cable box that is out with 1080p yet. I wish there was more insight into this. I get 1080p with my blueray and xbox but cable is only 1080i go figure lol. I hope this helps.
I apologize this is probably going to be a really dumb question but I just bought a Panasonic TC-P54G10.
After hooking up from the cable box to the TV via HDMI cable the "HD" channels are ranging from 720p to 1080i but I haven't seen any in 1080p..
Is this something in the settings or is this a cable box problem?
Any insight is welcomed.
