Why does everyone blame the screen for laser speckle?
I've been trying to figure out laser speckle lately and I keep seeing people say "just get a different screen."
My understanding is that the laser source itself is what creates the speckle in the first place, but the screen material can make it much more or less noticeable depending on the surface and gain.
What I don't really understand is why so many discussions end up saying "get a different screen" rather than looking at the projector itself.
Is the screen actually doing most of the damage here, or is it just making an existing projector issue easier to see?
And if two people use the same RGB laser projector but get completely different levels of speckle with different screens, does that basically mean the screen is the bigger factor in what we actually see?
