Yes! Always.
For the minor use, it does prevent metagaming. When the players cheat, and peak over to see what book I have out, then goggle whatever person/place/thing their character encountered from that book. Of course I also use the two factor prevention: the book I have out does not have my homebrew it in, of course. So while the players are all happy that they "figured out"(cheated) that the encountered monster can only do 1d2 fire damage, just like page 11 says......and they get all freaked out when the monster reduces their characters in size and scream "that is not a condition listed on page 101 of the rules!"
But the major use is to just have lots of needed information. I'm going to hang my own notes on the screen. And even print off better squares for some parts of the screen.
I have an old battered AC2 screen that I have used.....forever too.
But a 5.5E one? Eh, I'll ask for it as a gift maybe. It's the sort of easy gift a non gamer can buy.
