Used the calculator for the gt17's and got 13.51. That seems a bit long to me but I am double checking.

maximize picture on the tubeface and move the pj forth and back to fill your screen.
the calculator is a rough guide and no more.

I will need to go home to check. Are you asking the screen size or the setting for H/V on the projecor?

I just had another customer complain of a shaking H width issue, about 20 minutes after turnon. Turns out his width was at 100, which kills H output boards.
that's the second customer that's done that in the last year... I suspect you'll be on the low side of the width, say under 50, which will shorten your tube life. I typically set my Marquees up so that the width is between 60 and 80.

I am at 53 and 7 right now I might move it closer about a foot or so and go for 60-65. But part of this was to move the projector to more of the rear part of my man cave.

OK....moved up a foot and a half and did a setup again....64 and 13.....that is as far as I want to go. Looks great though.

Case I do not have an answer to that. But I do know I can go to an 11-12 foot wide to max at 13 1/2 feet.

2,5m trow for a 2m wide screen with HD10E lenses.
Remember i had a 3m trow for my 2,4m wide screen with HT17 lenses, so its a 1,25 x width.
Measured from the front of the lens to screen.
