Hey, everyone. Not sure if this is the most appropriate spot to post this, but need some help and/or validation on screen size (probably a DIY). Purchasing a JVC NX5. Room size is 24dx16wx9h dark walls/ceiling bat cave.
I previously had a 1080p pj with a 120" 16:9 screen. This time around I want to go with a scope screen (~2.35-2.4). I will not have an A lens; I'll be zooming in to fill the wide screen.
Just want to make sure my logic and math is correct. Since I had the 120" before, I'd prefer for the non-zoomed 16:9 image to not be less than that size. (I used this calculator
at projectorscreen.com for everything. If there's a better one I should use, let me know.)
For CIH based on a 120" 16:9 (~58.8" height), that equates to a 153" 2.40 screen. But, to fill the entire screen I'd need to zoom in to a 162" 16:9 equivalent right? Is that logic correct?
See the attached images.
Assumption: AT Seymour Center Stage XD screen. Advertises 1.2 gain but from reading, real world is really ~0.95? If the logic above is correct, then a 162" with a throw of ~18'6" and 0.95 gain will produce ~21fL. Non-zoomed 120" 16:9 only gets brighter fL from there. The big question, personal preferences aside: is this bright enough for 4k HDR
? Also, at this throw distance, its getting close to its fill zoom (1.85x of available 2.0x). Is that an issue? I could move it back as far as 22/23 ft throw if necessary, but then less brightness yeah?
Appreciate any insight. Feel free to educate me!
