Throw ratio

[p3eps]

I just want to check something before I order a new projector...

My sim projector is on a bracket on the ceiling. There's not much room for it to move, as I have a bike on the ceiling right behind it. It could move a couple of inches, but that's about it.
I currently have a Benq TH682ST projector in place - which according to the datasheet has a throw ratio of 0.69 - 0.76. I assume there are 2 numbers as it has a small zoom (1.1)?

I'm looking at purchasing the new Benq TK710STI to upgrade to 4K. This has a throw ratio of 0.69 - 0.83, and a 1.2 zoom.

The new projector would have a larger scope for zoom on it - so am I correct in assuming that I can just attach it to the existing bracket, adjust the zoom / focus, and that'll be that?

I think I'm right, but don't want to order this and then have to move stuff around! Can anyone with better projector knowledge confirm?

TIA 👍

Yes, if your existing set up works, the 710STI should work as far as distance from the screen. I replaced my 671ST with the 710STI and it fit in the same mount, and same location…..and a much improved image.

I actually got it last week - works perfectly.
The hardest part was trying to figure out how to get the projector off the bracket!!
