> A carefully shaped money-backed lever over the market is absolutely part of reason you never see DisplayPort inputs on consumer TVs, where HDMI group reigns supreme, even if the TV might use DisplayPort internally for the display panel connection. Curious about this. Is the HDMI standards group engaging in anti-competitive behavior to prevent DisplayPort from taking over on TVs? I've always assumed it was just momentum.

I was just thinking about USB-C vs Lightning... What if the EU were to mandate HDMI over DisplayPort?

  The EU Generally chooses the more open and cheaper alternative. They did this with phone charging, car charging and would probably do the same with display connectors. USB C is the cheaper and more capable connector

Another key is that HDMI carries more power than display port. There are dongles for your tv that can get all the power they need from an HDMI cable. Not so far display port. When it comes to use case, display port is better when connecting a fully independent device to a display and HDMI is better for connecting a peripheral to a system

  > Another key is that HDMI carries more power than display port. A quick look at Wikipedia's article for both standards shows that you're wrong: DisplayPort: 3.3 V ±10%, 500 mA HDMI: 5 V, 50 mA Which means at least 1500 mW for DisplayPort, and only 250 mW for HDMI. So no, the DisplayPort cable carries more power than the HDMI cable. And when you think about it a bit, it makes sense that DisplayPort carries more power than HDMI: one of the use cases for DisplayPort is an active converter to HDMI, which needs power for both its electronics and the HDMI cable.
