I have a new for me projector coming (Viewsonic PX727-4k) and I'm getting the room ready for the change. It's throw ratio is 1.5 to 1.8. The width of my screen is 120" so it seems the projector distance from the screen to the lens can be between 180" and 216". It'll be a ceiling mount and I have a joist at 184" and another at 200".
Any thoughts about which of these joists to use? Would the one at 184" result in a noticeably brighter picture (I'd like to use eco mode if possible to prolong the bulb life) and, if so, is there any negative to using it as opposed to the one at 200"?
I guess I'm not sure if there's a 'sweet spot" in these throw ratios or if the resulting picture is the same throughout the entire zoom range?
