not sure how it is now, but last time I looked into this it's because the board feed is run back through a control room for color correction, and then back into the display - if you run it directly on the display without color correction it's much better, this is one of the things that annoyed me the most but beyond my scope

They're color-correcting the board pre-display, and then presumably a second time from the camera's feed (of the full newsroom scene including the display)? Why? It seems at best unnecessary.

I would expect they'd color-correct the board feed in the control room when it goes direct to broadcast rather than through a camera, but I don't get why they'd ever feed that back into the display.
