Thanks for your help, ideas, suggestions.
I closed the curtain as-is, it’s as dark as I can make it. I could probably do a better job at closing curtains, pressing them tighter against the wall to darken.
But then… instead of a room with open window, open curtain, I’m making sunny weather into permanent dark due just a projector.
Once it’s dark outside I’ll try again. If it works well at natural night then I could elect to do laptop screen daytime, projector nighttime.
The product in software, so far, I cannot flaw it. Audio quality good. The fan not too noisy. So it’s only brightness really.
I am at 54 degs latitude. You’re at 38 degs latitude, and we passed the spring solstice so more daylight for me.
A winter product, not a summer product?
