Texan99's comment reminds me: participation in worship by th3e congregation is worth pursuing. I heartily disliked screens with song lyrics projected when they first came on the scene. As a book person, and a music-reading person, I liked having my Gestalt verses and my bass lines in focus as I sang. Leading worship in a painfully small congregation I learned a different lesson: people looking down and singing into a book do not build that sense of soaring elevation with their neighbors which leads to community worship; people looking up at screens do. It's just the physics of sound waves.
In an earlier era, when people had a limited repertoire - 100 hymns out of a hymnal of 250 - which did not change much over their lifetimes, they could sing up and out, using the hymnal only as an aid. Those days are gone. If you want people to sing together, they either have to all know it ( a very small number these days), learn it on the spot (call-and-response or extremely simple), or put it up on the screen so they raise their heads.
