Right ive got the PS3 connected to my LCD tv via HDMI, i went to test the display to see what i could use, and ive got all settings apart from 1080i or 1080p i cant remember which but anyway if i put a game in and turn the tv it automatically goes to 720p and starts the game, anyway whenever i quit the game the tv just goes to a blue screen and nothing happens? same thing happens if i turn the PS3 on with no game in?
