A few weeks ago they were using a shot that had a view of those plasmas at the very back of the newsroom, the area with alot of white. It looked quite brilliant, but they had to go back to the shot of the dark gallery behind the "sail".
I think it has got to do with the positioning of the desk / 'newswall', they are almost parallel [if you get what I mean when you picture it from the top] to each other resulting in such awkward angles.
