The desk is part of the newsroom_1. Forget what I said about parenting the monitor and text, that does scale them, but they don't move around correctly that way.

You could use the grouping tool to remake the set the way you like it. Spawn props then export the different pieces. It's a little complicated but gets easier with practice.

In this image I scaled the newsroom vertically 140%. I used the grouping tool to separate the lettering in the center and deleted the rest. Then raised the monitor.
