So I am playing Plants Vs. Zombies on my PS3 using a Roku TV, but I realized that it is not showing the full game picture. the sides of the screen are cut off, even on the direct viewing setting. I have seen on YouTube videos that there is more of the screen shown on this game, and I would like to have the full screen shown. there is more than enough room to show it, but it is just cut of by black bars. How do I fix this?
