You have to tell us if the YouTube video looks like the picture on the set or is worse due to these added effects.

Indeed, the dot pitch is coarse. Good suggestion-will experiment with the focus and see if I can subtly tame the pattern.
The best representation of the problem is the still image posted in my last comment.
