Still haven’t bothered replacing my curtains
Before I got the n3 ultimate, I was pretty sure I’d end up buying blackout curtains. I kept seeing people talk about blackout curtains and dark walls whenever I looked up projector setups. Two months later and I’m still using the same thin curtains in the living room. They still let some light through when they’re closed, but it really hasn’t bothered me much. Maybe the screen is helping too.
Most of my movie watching is at night anyway, and I’ll sometimes turn the brightness down a bit. I still use the projector during the day sometimes and it’s been fine. Direct sunlight is obviously a different story, but outside of that I haven’t really had an issue. So far I haven’t seen much reason to replace them.
