    A technical explanation needed.

    Equipment is Sony 65" OLED being fed ONLY from my modem via CAT6 ethernet cable.

    I go on YOUTUBE and select a 4K "relaxation" video (VP9) and play it. The feed is 1080P per the built in Sony "Nerd Diagnostics".

    What am I missing here?

    YouTube haven’t updated their Apple TV app yet for 4K support

    No Apple TV involved - the YOUTUBE App is pre installed on the Sony and diagnostics show VP9 codec. The Sony is being fed DIRECTLY from my modem via CAT6 cable.

    Bandwidth is showing as 3900 KB/s with 0 dropped frames. There are no artifacts displayed on the screen - pretty impressive image - but the diagnostics clearly show 1920 x 1080.

    Most likely the YouTube app on your TV doesn't support 4K.
    I'm not sure why you're asking on an Apple TV forum though.

    I have found that the title info is wrong.

    4K title but 1080P.

    That may be it - the best image quality that I have seen on this Sony is very good to outstanding - especially some of the GoPro F/A 18 imagery. Much of it it touted as 4K but 1080p is all I have been able to confirm thus far through the sets diagnostics.

    What is behind my question is if a true 4K signal (whatever that means) arrives at my modem - it is demodulated into 1 and zeros and fed directly to my Sony 4K. I should be getting a 4K picture but that does not appear to be the case.

    It is possible you don’t have enough bandwidth on your connection. Netflix requires 25Mb per stream to do 4K, and I believe they have a detection and if you can’t sustain a connection of that speed they downgrade you to HD. YouTube may be doing the same thing.

    Even if your broadband plan is for much higher bandwidth, I.e. a 200Mb plan, you may not be able to get 25Mb sustained to the YouTube and/or Netflix servers. This is why Netflix made their fast.com website and the Fast.com apps for mobile devices. That is a speedtest that uses the same Netflix servers that the videos come from, so you can see if your connection is fast enough to handle HD or 4K.

    Sometimes just normal internet congestion can cause limited bandwidth to certain services. Also your provider may have too many customers sharing bandwidth for you to get enough. Or the provider may be doing something to reduce how much bandwidth is sent to YouTube. It is hard to tell on all of those.

    Try doing some speed tests, and use multiple sites/apps. Especially compare Ookla (speedtest.net), DSLReports, and Fast.com. If you see sub 20Mb on Fast.com you are going to have trouble doing 4K from any service on any device. And if you see that there but super fast speeds on the other tests, your provider may be limiting what you can get from video sites.

    Shawn - I'll give that a go in the morning. My bandwidth should not be an issue but needs confirming. We are fairly low bandwidth customers of COMCAST - but ya never know.

    I tried about 10 more "4K" clips from various YOUTUBE channels and all showed at 1920 x 1080 - can't figure it out.

    I also have a 4K Sony tv, and with Youtube I sometimes have to change the quality manually to 4K in the onscreen menu,
    the one all the way to the right, from the like and dislike button.

    My download speed is averaging 52mb/s - tested through several different sites.

    I tried your suggestion and

    BINGO !!! - that worked - thank you.

    Now I can finally start assessing the image :)

    Saturday morning update after watching several hours of 4K feed on YOUTUBE - WOW, what an immersive experience!!! No artifacting / no banding / no crushed blacks or blown highlights / zero dropped frames - this is what I was hoping for after the expenditure on the SONY A1E OLED :)

    There may be some over saturation on reds once in awhile - more viewing time to sort that I guess. I'll go play with Vimeo some now and see how that compares.

    A lesson that I learned from the higher end audio world is to hear Count Basie - not over analyze the bass - trying to carry that over to the video world.

    It is actually quite good. The sound localization is insane.
