That's interesting. "TSA will ask you to stop". I believe I was told that in LEO lingo "asking" means something else than "requesting". As in, the former is (at least in theory) something you might refuse without any negative consequences.
What the monitors show is SSI. TSA personnel have a duty to protect SSI, which is why they will ask you to stop photographing the monitors.
However, the vast majority of passengers are not "covered persons" and, as such, have no duty to protect SSI. So there is no legal prohibition against non-"covered persons" from filming the monitors, provided they are in plain view and you are not interfering with the screening process. FYI, airline personnel are for the most part considered "covered persons."
