Ambient light and lumens
Every time someone posts a picture of a laser projector for their living room half the comments are just “turn off your lights bro" or "get better curtains". Like yes, obviously a blacked-out room is ideal. But some of us living rooms that aren’t dedicated home theaters.
I’ve been using the Horizon 20 Max and it does 5700 ISO lumens and for me the ambient light situation is so much better than I expected going in. Afternoon light coming in through the curtains it might be sometimes a little washed out but still very watchable. Not calibration session quality obviously, but for casual viewing, sports, kids stuff in the background etc it is totally fine.
Moreover, instead of a TV, the 120” image changes how you actually use a living room space, even if the conditions aren’t perfect. And when you want the real experience you just dim the lights a bit.
Lets say you have a good quality screen. What lumen threshold do people here actually find acceptable for a semi lit room? Is 5700 ISO lumens enough for you? At what point it would make even bigger difference? 7000 ISO lumens?
