All of a sudden every game I play on my PS3 is displayed in 1080p. Yesterday I was messing around with some options because I couldn't get 3D playback to work. I changed some audio settings (Linear PCM to Bitstream) and that did the trick.
Today I fired up some games and my TV now displays all of them in 1080p. Before, they would all display in 720p. The graphics and text are way more crisp, so I'm happy it's displaying this way. But can anyone explain me why?
