I think DisplayPort should definitely be factored into the discussion.
After reading about it some more, it seems the specification supports
either TMDS or DisplayPort signal being output by the port, which can
potentially lead to the same DVI-I naming issue.

If (hopefully when) manufacturers migrate to DisplayPort driven
panels, LVDS becomes a technically incorrect label. I think PANEL is
already as good as we'll get.


I propose a compromise between the two: list physical output ports
only, except in cases where multiple signals can be used by the same
port, simultaneously.

Typical Thinkpad setup:
  - PANEL
  - VGA
  - DVI (usually not physically present, but added via dock)

Discrete card:
  - DVI-1
  - DVI-2
  - TV

Discrete card with HDMI:
  - DVI
  - HDMI
  - TV

Above, with DisplayPort
2-port DVI-I setup that can drive 2 displays for port:
  - DVI-A-1
  - DVI-D-1
  - DVI-A-2
  - DVI-D-2


1-indexed numbers to be more unfriendly, and dropped where appropriate.
