They're not losing tbh. HDMI will remain for TVs (well, I actually think there will be a convergence, seeing as how
TV's are doing double duty in attempts at asserting themselves as proper PC displays), so DisplayPort will still go on in the PC realm for sure. As I was talking with you I decided to see what's going on with DP 2.0, and now I see the spec has changed since I read about it vaguely back in the day. DP 2.0 is now actually set to obliterate HDMI 2.1 at least in raw data rates. 77.37 Gbit/second in fact. Just wow....
I think these two standards will live on battling each other. One for TV's mainly, while the other for PC devices. So I guess I should retract my statement somewhat, but as things stand, HDMI has the high ground (which DP held when 1.4 was out for the past year and a half I think).
Am I understanding that you wish Displayport would have won-out in the TV sphere?
