If you are increasing the size of your screen of your front projection does it affect picture quality?

Question

I want my front projection from 100 inch to 200 inch will that reduce or decrease the picture or image quality on my projection? If yes how much will it affect?

Answer 1

Yes, the larger the screen, the higher resolution that will be needed to properly fill the screen.  By doubling the size you are essentially cutting the quality in half.

Have you ever seen standard definition tv on a large high-def tv?  Looks like c**p, doesn't it?
