Hi.
I changed galvo (to PT-A40) in my laser projector. When I want to display square shape it looks like a right angle trapezium .
Vertical lines are parallel to each other but right one is shorter then left one.
Horizontal lines aren't parallel to each other.
On the other words most right-up point of displayed image isn't in the place where I expect it to be.
I try to figure out what this happens. Does anybody have some idea?
