Sadly, AVR manufacturers have not been trend-setters due to heavy dependence on what TV industry does. For example, entire PC industry has video sources and displays predominantly with Display Port, yet no single AVR has those ports. As such, that new market is not available to AVR vendors and millions of PC users would never think of buying an AVR as it is not convenient to integrate those machine into PC home systems. Virtually every monitor has both HDMI and DP ports, for user flexibility. It's a norm. TVs have not been providing this flexibility and, by extension, AVRs have not either.\n\nUntil we get first TVs and projectors with DisplayPort, alongside HDMI, no AVR is going to intruduce them, unless, as you said, someone dares to become trend-setter. In recent years, vast marketing attempts have been made to sell AV gear to gamers with consoles. These attempts have been made with HDMI connectivity in mind only. Yet, the biggest source on potential new income from gamers comes from PC world where DisplayPort rules. There are many more gamers on PCs than on consoles. No one has dared to penetrate this market. This needs to change if AVR vendors want wider market and bigger revenues.\n\nWhen Displayport 2.0 comes out (probably by next year) that might change things a bit. The AVR industry still doesn't have HDMI 2.1 locked down yet. Still having too many issues. But that's to be expected when rolling it out as fast as they did. Everyone who purchased right away is a guinea pig for them. \n\nDisplayport doesn't have eARC which is what major TV manufacturers are pushing. So that could be a reason why they don't use displayport. Displayport also doesn't have low latency mode like HDMI does. \n\nI just read that the new Displayport 2.0 will have the bandwidth to hit 80Gbps. Unfortunately nothing on the market will ever hit that. Hitting 40Gbps is hard to do now. There is no 8k content and graphics cards for PC's are not able to push 8k 60hz and maintain 60fps or more. 4k is where PC and TV's are at. Sure TV market has 8k TV's, but that's a huge marketing push. Cable companies are still trying to get 4k content. I don't see 8k happening on the cable side of things for at least another 20 years. If at all. The costs to shoot in 8k is too expensive.
