Hey everyone. I have a basement that's about 28'. I wanted to get a 125" diagnoal image out of my HD131xe and i installed it at about 25ft distance. But according to Projector central calculator, you only have to install it at 10' to get that big of an image? How's that possible? I will get same size image if i move it to 10' from 25' away? !

Didn't we go over this already in another thread?
Yes it is very accurate. At least for the model you have.you are looking at the wrong number. It is 10" offset not 10' viewing distance

I'm not sure at all what you are saying.

With the HD131xe, if you are using a 125" screen, then the lens MUST be between 13'7" and 16'3" from the screen and must be 10" above the top of the screen. The calculator shows you exactly that when you set your image diagonal to 125"...
