1080p on a 720, but how? - Blu-ray Forum

ObiMcD · 09-03-2008, 06:29 AM

I'm not sure if this should go on this forum or the PS3 forum but my roommate bought a new TV tonight, a 37" LG30 720p, and so we hooked up my PS3 to it when it went to automatic settings, low and behold it claimed that we could display at 1080p, the display was set at 1080p and looked fine, but at the same time we were wondering if it was really 1080p, maybe the wrong TV in the wrong box or something like that, or somehow the TV was able to down-rez the 1080p signal into 1080i or 720p. Subsequently we watched an HD DVR recording of a few shows on the TV and it looked a bit grainy, like maybe it was 720 playing on a 1080, but I haven't been around enough 1080p's to know for sure. Any ideas on why we have such a potentially sweet problem?

The TV was receiving a 1080p signal, but downgrading it

The TV is smarter than you think it is. It receives the 1080p signal but it will only show it at the maximum resolution of the screen. So you are watching a 1080p signal at 720p.

On a side note, I too have a 720p TV and noticed that the picture looks much better with the PS3 set to output only at 720p. When on 1080p the picture was a bit grainy and blurred.

Yep, signal is in 1080p, but what you see isn't.
