Comparable material from Stewart vs the ST Matte White 1.1 gain?
I currently have a 120" Silver Ticket White 1.1 gain screen. I noticed the Wire Cutter compared the Silver Ticket to the Stewart StudioTek 130G which has a 1.3 gain. However, I've never noticed any sparkling from the Silver Ticket, it appears to reflect evenly in all directions, and can be viewed even from extreme viewing angles. Thus, it appears to be a closer match to the StudioTek 100, since that material is a Lambertian surface with no maximum viewing angle. Indeed, I've found that for excellent results with a JVC RS-49 projector, the Silver Ticket requires a fully darkened room (dark walls, ceiling, carpet, seating). I had exceptional results with a room with complete light control, black velvet coated walls and ceilings, as well as a black rug, and dark furnishings.
The recommendation for the StudioTek 100 indicate that it is only for fully darkened rooms with total light control. Silver Ticket makes a similar suggestion but I see a lot of people using it in rooms with white walls and ceilings. Specifically, they say: "Best results occur with a dedicated theater with little no no ambient lighting and dark, matte-colored walls."
Perhaps it's simply that the StudioTek costs 10x more so it wouldn't make sense to use it in a sub-optimal manner.
I'm considering upgrading to a 120" screen with StudioTek 100 material and am wondering if controlling reflected light of walls/ceilings will be any more of an issue with the StudioTek 100 than the Silver Ticket. I have some samples on the way of the StudioTek 100 and 130, but I'm not sure how helpful that will be in answering my question. Any advice would be much appreciated.
