We're...not, though? Sure, computer-based displays are supporting various DisplayPort standards more broadly all the time, but TV-based displays are still all-in on HDMI, and the #1 reason (well, OK, the #1 reason is "because that's how it's been", but the #2 reason) is because the big TV/movie companies demand HDCP—DRM on the cable.
