HDMi foundation is founded by companies who own the home theatre environement (mainly movie conpanies and television) who puts DRM on HDMI to make it harder to illegally copy content like movies, ao they will always want to be anti open source because thats the request of streaming services/movie businesses. Its why for example, mobile devices have widevine levels. those levels basically determine how "unlocked" the device is and services will refuse to offer full functionality to unlocked devices because of it, be it audio or video.
Members of VESA, who control the displaypprt standard are generally computer companies are mostly not in the business of media, so they value specs over drm on changes, which for example a use case is that displayport allows for daisychaining diaplays.
I don't know a single person who has ever used HDMI to steal copyrighted content. Seriously? Who would rip a 2 hr move by watching it vs the 10 min it takes to rip a movie digitally.
Like shit ya got CAM, WebRIP, BRRIP and SCENE. I doubt HDMI was used in any of these scenarios.
technically speaking, every gamer who capture cards to bypass when games on PlayStation has an explicit mode that disables built in recording when a cutscene is active is an example.
Decades of being the standard in a/v. That's like asking, why don't we get rid of gas stations and just install electric chargers? Well, everybody's got gas powered cars.
AV things sure since they stick around longer, but computers? When was the last time you saw a high end GPU with VGA or DVI? And they already usually have mostly DisplayPort with just one or two HDMI ports
Well, I wasn't referring to that ecosystem. That ecosystem is already on display port. The reason HDMI is so prevalent is because it's the standard in audio-visual equipment. Why would I talk about computer equipment when it's not the standard there?
The point still stands. Everybody has equipment that has HDMI, and to phase out that standard in equipment going forward is phasing out equipment people already own.
Feature-wise probably next to nothing, and it's usually behind one or two generations in terms of bandwidth. HDMI is often the only port available on TVs though, so GPU makers likely can't afford to just leave it out.
They should anyway. New tech TV's are all smart these days and the dumb ones are made for two decades ago. At this point we are better off with a PC monitor and separate speakers. Built in speakers are shit seemingly as a requirement. I use a video port switch for extra inputs without needing to use the on screen menus or just running out of built in ports.
