At nearly 2:1 throw ratio, with a projector that is not super bright, how bad will hotspotting be in general, and the really bad effect you are talking about that is super distracting, will this be constant or just for scenes like panning over a blue sky that is very uniform, so it's easy to see the difference in brightness?I said change direction in terms of going any direction that you need to go to avoid a hotspotting. I was not advocating a new projector. There are many things that you could consider. smaller screen. Sitting closer to the screen. A different screen. Settling for less foot lambers. A multiple of things that you would have to weigh.
I'm not sure if you've seen hotspotting before. But when you see it, your eyes will focus to it multiple times per minute. It's like seeing a stuck pixel turned red on an LCD display. Your eyes always focus to it.
if you don't want to entertain any other ideas, you'll have hotspotting. And you're not going to like it
I'm definitely looking to avoid bad hotspotting, but it seems like at least some screens around 2 gain dont have a bad problem with it. So it's a question of how high can I go before it's a bad problem, with low lumen projectors and a pretty long throw distance.
