Well HDMI is better than all the standards I used before it. Never did something with DisplayPort but for what I can tell it's Apple related (right?). I used DVI-I, DVI-D, VGA, and even old stuff in the past.

There is the vesa standards organization with a pretty good history of successful display connections standards vga(analog video) dvi(digital video) and displayport(packet video) and very little drama affecting the end user with how the connection is used.

Contrast this with the hdmi consortium which put together the hdmi standard. originally hdmi was just dvi with a built in audio channel. and while I will concede that the audio channel was a killer feature and resulted in the huge success of hdmi. They really did very little technical work and what work they did do was end user hostile (hdcp rights management)

It really is too bad that display-port is sort of relegated to computer monitors as it is better designed and less end user hostile than hdmi. but hdmi with it's built in audio channel won the market for digital video connections and by the time display port was out people were, understandably, reluctant to switch again. While display port is better, it is not enough better to be for the end user to care.

Have you even bothered reading any discussion here? I can't downvote you but its easy to see why others did so, a very lazy and clueless comment about very basic of tech everybody uses, on Hacker news. You can for sure do better.
