Being somewhat familiar with DIY LCD PJs, you must be either using a very bright panel or some such adaptation to even get a watchable image from 22', or you have outfitted the PJ with a special lens that has an exceedingly long Throw ratio.
If the lens can give you 100" diagonal at that distance without bottoming out on Zoom mode, your doing something that even a Eposn 8350 cannot do, and the Epson is judged to have the widest Throw/Zoom ratio of any PJ currently on the market.
Now of course you can always go bigger, but the amount of lumens your producing will either curtail or assist such a choice. I don't know what your dealing with in that respect either, so understand that my comments, as well as other's can only be based on known values and specifications.
The only way to be certain is to always try your best to reduce distances commensurate to the size screen being utilized.
And BTW...cut Kirnak a wee bit of slack. This is a DIY Forum, and the way you stated your request did seem somewhat dismissive of wanting to be too bothered. And in the all in all, someone with that sort of mind think going into a DIY project just might...just might mind you...decide to cut corners or simply not do all that needs to be done to accomplish a DIY Screen that is more than worthy of note.
When that happens, all too often the application itself takes the blame...and we have another disgruntled Poster. The decision to try to take too easy a route often goes hand in hand with lessor results...or abject failure. That in fact we do not see hardly any of such people railing about the injustice of the work ethic vs. end results obtained via the DIY Screen making route should tell you about everything you need to know.
Rephrase the request and I'll betcha someone with extra paint left from having mixed up a gallon for a 100'er just might be really happy to oblige ya!
