2K shows on my Xperia Z2 but when I select it the video freezes and YouTube app starts to run slow. Every other resolution works fine, will 2K not work on a snapdragon 801? Im sure the LGG3 had snap 801 and a 2K screen. Im using Marshmallow existenz rom locked bootloader. Thanks for any help.

    In Xperia XZ Premium there is property that enable 4K(2160p) on YouTube app
    tested on Xperia Z5 Android 7.0 2K (1440p)

    add this line into your build.prop
    # 4K for Youtube

    no need to set display size on cmd or terminal.
