If you squeeze a pillow in the center it's narrow there , wider on both ends. That's the visual description of the distortion you see with the anamorphic lens on a flat screen . To compensate you use a curved screen OR use a regular flat screen and overscan the image an inch or so until the image fills the screen.
But here's a hitch though . The new Paladin and Pheonix lens from Panamorph are vertical compression lens. The distortion is not pincushion, it's actually barrel shaped ( as in the old wooden barrels), narrow on the ends wider in the middle , exactly opposite
to pincushion. These new lens are really designed for a flat screen but will work on a flat or curved if you overscan.
Further the projector is back from the screen the lesser the distortion.
