Hello
Depends on the signal but the HD10 series all have about the same throw but across different ranges of magnification.

I can't remember/can't find those throw ratio numbers.
Curt kicked me in the @$$ last weekend to get the PJ I have mounted. So after a year of sitting on said appendage I am looking at plans again.
But my numbers don't add up so I'm looking for a sanity check on throw ratios.

Hello
Test with your actual signals on a table and get it right before you mount it.

Yes, but what about the projector. Based on the news you told me last weekend, you haven't exactly been sitting on said appendage either....  
1.35 X the width of the screen should work.

And you don't even know the half of it. Life is crazy so far this year.
After I spend this week getting ready for the A/V garage sale I need to find space for the 100 pounds of vinyl I had delivered today. That means shelving. But after that I want to get started on the room. It's been way to long in coming.

You can use the Barco Lens program for example.
