I had my 8ft Othello electric Owl screen swapped out due to a problematic motor / screen sticking problem but I have noticed that I am unable to fill the screen correctly with the image. The vertical edges are not straight and the screen is not true 16:9. The left and right edges bow inwards at the middle by more than a quarter of an inch meaning that if the image is perfectly aligned to the top and bottom corners the black side borders are overlapping into the image. Also, I could not understand why I have been unable to fill the height when the width s filled and have measured the screen white area only to find it is 95 3/4 inches wide by 54 3/8 inches high. Unfortunately over size in one direction and under in the other. I noticed this on the original but never actually measured it assuming it was caused by my additional short throw lens on the Z10k. Installing the new one today I took the time to measure and use a straight edge and am rather disappointed with the results. Has anyone else with one of these screens noticed similar problems? Thanks.
