  • What Is The Best Gain For A Projector Screen? - Pointer ...

    2022-1-4 · If your screen’s gain is 1.5, it’ll give off an even brighter reflection, much brighter than the projector’s light. So a 1,000 lumens projector will come out as 1,500 lumens with a 1.5 screen gain. In the same way, a ratio gain lower than the standard will reflect less light. Going back to our 1,000 lumens projector example.
