If someone could enlighten me as to what the problem is I would appreciate it. There is so little content at 1.78:1 that black bars are going to happen whether or not the display is native 16:9. Also, I would certainly use a 16:9 screen with these products and let the border absorb the black pixel area. We have included imbedded test patterns for easy setup with such a screen.
Hi Bob - the concern (at least mine) was that I'd have to deal with light spill above and below my screen (on my wall) if I set up a 15:9 projector to completely fill my 16:9 screen. Sort of the same issue you face when using a 16:9 screen with a 4:3 projector, only with smaller letterbox bars.
If you have a traditional fixed screen from one of the well known screen manufacturers, then you probably don't care that you have 3" etc. of extra letterboxing, since your screen border will likely absorb it. But there's so many different types of screens, setups, and borders in use, and the extra spill may or may not make a difference to you. Maybe this is worrying about nothing, I don't know.
Take my setup for example - I have a 16:9 DIY screen with no border. I use felt to mask the screen for 2.35:1 material. If the projected image is 15:9, that means I have projected black on my screen wall above and below the screen, and above my 2.35:1 masking (see my Gallery). Now my screen wall is dark brown, so it probably won't be noticeable, or will it? I don't know - I'd rather not find out. Also, what if someone had my exact setup but had a white screen wall? The spill would probably be clearly visible then. Not a big deal for sure, and certainly addressable with a border or masking, but having a true 720p projector was one thing I found appealing about the IN76 vs the other offerings such as the HC3000, which AFAIK projects a 15:9 image.
At any rate, it looks like a moot point since it sounds like the 48 pixels will not have projected black, and for all intents and purposes, the IN76 is a true 16:9 projector.
