    Hi,


    I've been using the Rock64 builds of LibreElec and enjoying 4k HDR output for a while now. This build for example: LibreELEC-RK3328.arm-9.1-nightly-20190501-6f2af43-rock64


    Just got an RPI4 today and I'm running some tests.


    Setup:


    I've got it up and running using this: LibreELEC-RPi4.arm-9.1.001.img.gz


    I got a micro HDMI cable from Amazon to use with the PI4: https://www.amazon.co.uk/gp/product/b014i8tvli


    which I understand supports 4K HDR


    Issues: I can select resolutions of 4096x2160p @ 30, 29.97, 25, 23.98 and 3840x2160p @ 30, 29.97, 25, 23.98 --- but not at 60fps


    Also the same content that used to be 4K HDR under the Rock64 build won't activate HDR on the RPI4.


    It does play at 4k though. The HDMI is plugged into the same TV and same HDMI socket as the Rock64 was and it's playing the same 4K HDR title ... but no HDR.


    Anyone got any suggestions. Happy to provide any info if it helps track down problems in the RPI4 build and HDR.


    Thanks,
