I'm running Lion on a MacBook Pro, and am having a weird situation on the lock screen. When I shut down or restart the computer, and the apple icon appears while booting, it is a much lower resolution than the standard resolution of the MBP -- it's a much bigger icon, and looks pixellated around the edges. Often, when it gets tot eh password stage, my user icon and password entry box appear in the lower right hand corner of the screen and half off the screen as well, as though I'm looking at the upper left quadrant of a much larger screen. When we actually get into the OS, it looks fine. I'm looking for a way to fix this and make it stop happening.
