    Just pointing out, 4k hdmi when transferred over ethernet or wifi is never going to be true 4K as it's roughly 40gbps. You also lose out on HDR and Dolby Vision. Really not worth it at all.

  • @theonlydarian
    @theonlydarian Před 4 lety +2

    4k at 30hz uses roughly the same bandwidth as 1080p at 60hz, this is why HDMI 1.4 spec (older laptops, pcs) support 4K up to 30hz. HDMI 2.0 is required to support 4k over 30hz

      @@shawnheatherly9219 I agree but regulations don't have to make any sense, I think there is an EU regulation that means banana's have to be grown straight (not sure if it still applies), regarding the signal strength it's likely so it doesn't interfere with others using the same frequency, regarding the other frequencies it is likely to stop things like pirate radio stations and signal blocking. I would not worry to much about it as any wifi device you buy in the UK (unless you hack it) is restricted to only broadcast up to the signal strength limit.

    I don't understand the premise for this video. 1080p/120 and 2160p/30 is within same HDMI specification - HDMI 1.4. Why is the reviewers premise that it should be so much harder to project 4K/30 compared till 1080p/60? Is he even aware of the HDMI specifications? Is this video a spoof? Did I miss the joke?

    • @lupsik1
      @lupsik1 Před 3 lety +7

      Didnt watch the video past the 2nd minute yet so i might take my words back but I felt i need to reply.
      1080p is is about 2 million pixels, 4K is about 8 million pixels so 4k/30 compared to 1080p/60 is 2x more bits of information to transfer.
      2 times more is not ridiculous but its a lot more, for reference right now we double processing power of consumer cpu's about every 5 years.
      The video signal going over an HDMI cable needs to be in sync with the graphical processor that sends the data, afair it determines the frequency of updates and expects to have new data in those even intervals if the frequency fits its specification.
      To allow this wirelessly the receiving device must have at least a small buffer for when a packet gets lost and needs to be sent again etc. so that you dont experience stutter, flickering etc.
      If the wireless connection isnt able to fill that buffer faster then its being emptied then you're missing the time windows for when the image was supposed to be displayed and end up with a black screen, then some image and black screen again and so on.
      My point is, the hdmi specification might allow 4k/30fps data to be pulled from the receiver but the wireless connection has to have enough bandwidth to provide that data on the receiving side.
      Sorry for the terrible explanation, but I dont understand why you're talking about HDMI specification when the discussed problem is sending the raw uncompressed data wirelessly which is a whole different thing from f.e. streaming compressed 4k video from netflix.

    Yeah, 60Hz, I don't think 30 meters is legit. There were some works being done for wireless VR that were doing to use 60Hz (Wireless AD) they only could promise same room/open room coverage. That is pretty cool though.

      Bit different to VR mate. As it's essentially two screens and it needs to be at a higher refresh rate than 60Hz as it will cause motion sickness very quickly.
