The HDMI Forum has rejected our proposal unfortunately. At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.

    HDMI didn’t succeed over display port; they’re two different formats meant for two different audiences.

    • HDMI is meant for consumer electronics like TVs / set-top boxes because it focuses on delivering a little bit of everything (audio, video, network, DRM, etc) in a single cable for the best, easiest (minus the DRM) singular TV / device experience.

    • Display port is meant for computers because it focuses on delivering the best responsive multi-monitor experience.

    In other words, if you are working or gaming on a computer, you should be using Display port; however, if you are using anything else, you should be using HDMI.

        Regardless of the cable that came attached, check the monitor to see if it supports a Display port – It most likely does. Your monitor likely came with an HDMI cable for sake of cost reduction (I guess better than no cable at all). If the monitor doesn’t support Display port, it means that manufacturer didn’t build or manufacture that monitor to be a true computer monitor class product.

          I know it’s probably for cost cutting. But the monitor does indeed have a DP input option. Maybe the HDMI is included because it has inbuilt speakers and as far as I know those aren’t usable thrpugh DP and I don’t know if it has a separate audio input.
