I'm sure this has been asked before but my search didn't turn anything up.
I just set up my PS3 to output to a Panasonic AE900 720P projector. I set the PS3 display output settings to include 480p and 720p, and skipped 1080i and 1080p. When I put in Blackhawk Down as a test, I noticed on the projector's menu screen that the output was only 480p.
Is it not possible to output BD video at 720p to match the native res of my projector? Am I missing something? Not that 1080i looks bad, but I assume the scaler in the PS3 is better than the one in the projector.
