DisplayPort and 4K

HDMI exists because the corporations behind the HDMI group are the ones that make most of the TVs and dvd boxes. So by pushing HDMI they get to use it for free while the competitors have to pay extra and are at a disadvantage. Nvidia and AMD are not on the HDMI group which is why on pro and enthusiast hardware displayport is pushed much more. My current gpu has 3 displayport and 1 hdmi.

On the tv side, the benefits of displayport are less important since most users are not watching 4k 144hz content and hdmi is now capable of playing 4k at 60hz. So hdmi is not only pushed by the corporations but is also the most convenient option the users want since all of their other hardware uses hdmi and it works fine.

Honestly I think GPUs should drop the hdmi port entirely and ship with a displayport to hdmi cable which works fine because displayport gpus also support hdmi and dvi over the dp port.

You forgot to mention that besides royalties, the main reason HDMI is used in consumers electronics is that it also streams audio with CEC as apposed to Display Port that only does video.

For most consumers, plugging in just one cable that does everything is a lot more convenient.

Edit: sorry, didn't know DP can also stream audio, my bad

DisplayPort does audio. The main reason for HDMI is DRM.

DisplayPort has done HDCP and DPCP DRM since early on, so I don’t think it’s that.

DRM was added to DP later on, IIRC, it wasn't part of original standard.

HDMI adding audio and DRM was the core of the proposal, plus a connector that was more consumer friendly.

I think HDCP is also one of the top reason. Does display port support content protection like HDMI?

This is a common misconception. However DisplayPort transmits audio as well.

Thanks for pointing it out and all the correction.

I also thought DisplayPort was for Video Only.
