Sorry but you are just plain wrong here so one last reply now to explain it to you then I'm choosing not reply to you any longer on this topic. This is about video decoding and video output, and 2GB VRAM is enough for 4K output when 4K HDR videos are hardware decoded using the dedicated video decode engine on these cards. You are probably confusing hardware accelerated video decoding playback with the GPU GFLOPS graphics requirements for playing PC AAA-games, which is not at all the same, that is like comparing apples and oranges.

Do you honestly believe that Nvidia would release a card with a "HDMI 2.0b" port that is not capable of 4K output, (not even 4K video playback output) just read the specification:

You can compare this to the first Raspberry Pi with only 256MB of RAM which Kodi can today do H.264 decode and output 1080p video on, and that is with shared RAM used for both system and video. So why should 2GB of dedicated VRAM not be enough to decode and output 4K when the GPU have a dedicated video decode engine. You can also compare this for example Amazon Fire TV 4K which only have 2GB of total RAM, and again that is shared between graphics and system, it too have a dedicated video decode engine so it is capable of decoding and outputting 4K video without a sweet. And many non-Android 4K hardware players have much less RAM than that.
