    The HDMI licensing BS makes it rather useless. At least most monitors and GPUs have DisplayPort now. It’s mostly just TVs that are still limited to HDMI.

        It’s not just limited to PC’s. USB C has a DisplayPort alternate mode and many phones and tablets support it now. I’m rather surprised manufacturers haven’t started putting USB C ports on TV’s for video input yet.

          Ah, i forgot some phones support straight displayport over usb. Still, wired display out on a phone isn’t exactly a common use case.
