When I'm in game, the actual GAME is in 1920x1080. But My screen is cutting off at a much lower resolution.

I have all my resolutions at 1920x1080. When I start a game, it launches the Yuri's Revenge opening scene in a very small resolution. I have to hit ESC to end the scene and begin the game. When I'm in the game, it looks like the resolution is 1920x1080, but it's the same resolution as the opening scene. Which is MUCH smaller. The screen is cut off from the left (No menu shown). If I ALT TAB it shows the full game, but when I enter the game it's not the same resolution. Maybe it's because the opening scene is being launched at the start? I can't find a solution. Please help
