So, I can't actually project a 1080x1200 image? It says the chip is 1080x1200, but maybe it doesn't actually let you use it all?
Is it not the one I linked above? Because the spec sheets there say it's 1920x1080 native. Now DPI does make 1920x1200 projectors so maybe I found the wrong one.
My reasoning for the vc lens was to get increased brightness and pixel density, but maybe I don't really need it. I'll try it with just the lumagen and maybe add a lens later.
Well theoretically you've already got plenty of brightness and pixel density for 16:9, that won't change when you watch scope content. Without a lens scope is the same brightness and density as everything else.
Where you really "need" a lens, or where it becomes useful, is when you're trying to make scope the same height as 16:9 (ie Constant Image Height, CIH). When you do this, because scope is larger, it is necessarily dimmer and less dense. A lens mitigates some of these "losses" relative to 16:9. If you've got a 16:9 screen, I just don't see the point in the cost/complexity of a lens setup since everything you watch will be the same brightness/pixel density.
Now if you've got a scope screen, that's a different story. A VC lens can work in such a case, but you either need to leave the lens in place all the time, or be able to zoom (which requires a 1.33x zoom range, which your Cine probably doesn't have), either way a Horizontal Expansion lens is a much better choice for a scope screen/CIH setup.
