The battle bridge main viewscreen aboard the USS Enterprise-D in the three episodes in which it appeared: "Encounter at Farpoint"↖️↗️ "The Arsenal of Freedom"⬅️➡️ and "The Best of Both Worlds II"↙️↘️. I think ↖️⬅️ are the same footage re-used and colored slightly differently.
@gaghyogi49 - Something I noticed about the Battle Bridge viewscreen is how it looks to be a deliberate callbackl to the Auxiliary Control Room screen from The Doomsday Machine.
