I noticed in the photos that you are shooting at a downward angle.
Do you get the same if you're either even or shooting up at it?
We already know that the light filter does some strange things when you look down on the screen. What we don't know is if what you are seeing is only seen when looking down on the screen.
In your photos its also obvious that you were pretty close to the screen( keystone distortion). Back up and get even with the center of the screen and see what happens.
