Now there is a lot of different screen material has been developed to counteract or help to maintain and increase the projection image quality . These material have surface up recently by different manufacturer for those conventional standard throw lens for Home Theatre market .
The reason is the projectors are getting brighter and brighter to be able to produce good HDRs and wide colour spectrum . These also allows more flexibility of how you can use in different environment and colour settings . We can do the conventional Bat Cave concept Or have ambient lights while watching .
The new screen material have a high silky smooth surface for 4k projection , anti hot spot in Bat Cave mode , wide viewing angle , increase black levels , does not loose white points and deeper picture depth .
Yah bro Kaydee6 came by to my demo area and look at the physically screen with lights on and off . He was worry that there will be hot spotting and resolution surface . As it was matching with his 4k projector.
