The only reason HDMI still exists over the vastly superior DisplayPort is the cable length. The DP standard, if memory serves, limits the cable to 3 metres / 10 feet so the max cheap passive cable you can buy on Amazon is obviously 15 feet. Meanwhile, the HDMI standard has no cable length limit but in practice 50 ft is the longest passive you can buy.


I'd say the only reason HDMI still exists is because everything has HDMI built in. The best standard doesn't always win, the most prolific one does.


When DP came out in 2008 it already supported 4K and HDMI didn't.


I don't see how that's in any way an argument against "the best standards don't always win".
