NothingProjector's current long-throw screen page explicitly lists the Valerion VisionMaster Max among example compatible projectors. That makes its A4 sample relevant to owners who want to test the material before a full-size screen.
Start with screen type, not brand matching
You do not need a screen from the same brand as the projector. You need compatible throw geometry, enough brightness at the target size and a surface that behaves well with the projector's light source.
Why laser speckle deserves attention
Independent 2026 testing of long-throw screens with modern RGB-laser projectors found meaningful differences in speckle between materials. Test large single-color fields and moving sports scenes rather than judging only a colorful demo reel.
NothingProjector versus Valerion's own Fresnel option
The NothingProjector long-throw material is listed at 0.8 gain and 170°. Valerion's Fresnel screen is listed at 1.8 gain and 90°. That is a real brightness-versus-viewing-geometry trade-off, not a small spec difference.
Check the long-throw material with your projector.
The A4 sample is the promoted offer; it is intended as a material test rather than a claim that every room will produce the same result.
