Howdy all, considering a Seymour Screen to save some money over a Stewart and have heard good things, however I can't find much info on the Glacier White material vs. the Stewart StudioTek 130 G3. I want/need a 1.3 gain screen to take advantage of HDR, with minimal sparkling/artifacts with a fine/smooth enough surface to resolve 4K. Searching this long there there's only one mention of the Glacier White and it doesn't give much info. I do NOT need an AT screen.
Looking at 128" Diagonal Metro frame 16:9 by the way.
Appreciate any insight on whether this would be a good choice over the Stewart!
