Couple items to update:
was out to my place in November and did a full video calibration of my JVC x990. I'd like to give a shout out to him as the work was GREAT and well worth it! The improvement was very noticeable and worth the price IMHO. Thanks Chad!
Also, just ordered a Severtson, Cinema White Micro Perf Screen (1.3 stated gain but with perfs figuring more like 1.2). Bought the material only and will be using my existing Falcon frame. I've tested the samples onscreen and the bump in brightness is VERY nice. Based on brightness calcs (these calcs figure 1500 calibrated high lamp lumens and a 25% reduction in bulb brightness at 500 hrs) I'm figuring the following fL for my setup:
120" diag 16:9 aspect - current woven material 22fL
120" diag 16:9 aspect - Severtson micro perf 34fL
140" diag 2.35 aspect - current woven material 15fL
140" diag 2.35 aspect - Severtson micro perf 23fL
35% brightness increase overall which I'm pleased with for the price of the upgrade (screen material only).
The reason I'm doing the screen change is for more brightness to screen for nice(ish) HDR. 22fL and 15fL respectively just didn't provide enough brightness for the material I am viewing (4k HDR BD and 4k HDR video games). I was absolutely pleased with my current material (Falcon Horizon woven material) with SDR content. But then HDR hit the PJ scene and all of a sudden I needed (significantly) more brightness. With my current material, I don't believe I'm levering all of the benefits of my JVC x990 PJ and thus the change to micro perf.
I can tell from the samples that micro perf screens are a completely different game than woven screens. I don't anticipate the material will be as easy to work with as my woven material when installing on frame. I'm also not sure how my speakers may 'move' the screen. I have approx 4-5 inches between screen and speakers/subs and my large subs port to side not front so hoping for the best. Real world results remains to be seen. I'll check back when its done and I have some impressions!
