My PS3 hud settings are set to 1080p.

When the game loads, it loads in 480P and I get a warning message that I should set the resolution to 720P. I have looked around the game and could not find any options to change the resolution.

My TV does support 720P/1080p all of my other game automatically load on either 720p or 1080p.

What can i do to load my game on ps3 at 720P
