An interesting take on the lighting issues, and one that would be easy to show instead of tell in TV, would be to use mixed reality. Have the displays show up when focus character puts on glasses, disappear when without them, and possibly even enhance the "otherness" aspect of the displays. BTW, your example about showing screen in TV reminded me of, iirc, pilot episode of Babylon 5 - where camera suddenly cuts to Amiga-rendered ID card filling the whole screen (rotoscoping it otherwise would be too costly at the time).
