Listed below is the set-up I plan to use in my HT. The question I have is this: My room dimensions are 11 X 21. I would like to go with the biggest screen possible. I would like to go with a 108 in horizontal size which makes it 135 diagonal in 4:3 and 124 diagonal 16:9(I believe). The question is will the Optoma be able to accomplish this? I am planning on doing a ceiling mount only. Is it easy going back and forth between 16:9 and 4:3? Would love some advice.

I purchased an H79 so that I could use the power zoom to fill my 4:3 scren width with either 4:3 or 16:9 source material. I'm using a 4:3 Da-Lite Model B with a width of about 80". My throw is about 130". I selected this throw due to room constraints (i.e. anyone want to hit their head on a projector while playing pool?), and it satisfied the online Optoma H79 distance calculator for 16:9. I *assumed* it would allow me to fill the screen witdh with a 4:3 source material, which I have subsequently learned was an incorrect assumption. Using the power zoom, I cannot widen a 4:3 pic enough to fill the 80" screen width. I cannot mount the unit at a longer throw (e.g. 17'?), which I beleive was a recommendation from one of the articles referenced on this forum. My question is, does some sort of screw-on lens exist that I could use to satisfy both formats using the zoom control? I emailed Optoma tech support and they suggested I get a scalier (yes, that's how he spelled it). We won't go there... Any help that anyone on this great forum could provide would be greatly appreciated! Thanks!
