calibrating problems

[jefree]

My projector is an Optoma HD37. I am calibrating the printer and the grid is showing not square. At the bottom it is 48mm wide and at the top it is 47 mm wide. I can't find the control to fix it, apparently it is not a tilt problem because it isn't fixed by tilting the unit, but then again I'm just trying stuff.

I suggest reading the instructions, the forum and watching the videos carefully before posting so many questions in the forum. Those answers are already in there.

You need to use the Projector's keystone function to adjust that.
