I have the same projector. Although, I cannot help you with regard to the PS3 because I don't have one; I can tell you that your (our) projector can accept the 1080p signal, however, the resulting display is 720p. You can easily find this information when you select the Menu then the Picture submenu; you will see that only if you are using Component or HDMI will the screen resolution be displayed. This information is on pgs. 40-42 of the manual. Sorry I can't help you with the PS3 side of things. Hopefully someone will chime in and help you.
