The System Information report for Graphics/Displays on my MacBook Pro Retina (Late 2013) shows the following info for the internal screen and for an external Acer monitor.

What is the meaning of that last item,
Television: Yes? This hardware is not actually a TV, just a display with HDMI, DVI, and VGA inputs.
I understand that modern TVs are indeed just monitors with an OTA tuner and speakers implanted. But I wonder, given the lack of a tuner, what the meaning of that item in the report specifically means.
