Help me understand optical keystone
I have a question regarding my projector image. My projector are very slightly angled down and therefore produce a trapezoid image. But this is almost entirely happening on the left side only going from bottom too top becoming more and more pronounced in that direction.
Why is this? Shouldn't the right side be affected too?
