    Skylake HDMI 2.0 with chroma compression in Linux

    boost

      Hi,

       

      I built a new Skylake system with a 6700K and a Asus Z170-Deluxe. The mainboard converts a displayport out to a HDMI 2.0 out with a HC2800 chip.The OS is  Fedora 23 with rawhide kernel 4.4 and xorg-x11-drv-intel-2.99.917-16.20150729.fc23.x86_64 driver. I have connected my TV to the HDMI out and I want to set the display to 3840x2160@60Hz.  Using xrandr to set the resolution only produces an error on the TV: "Not supported". Unfortunately my TV only supports this resolution with chroma compression in a YCbCR420 color space, which works on a different PC with a nVidia card.

      How do I get this setup to work in 3840x2160@60Hz with integrated graphics?

      Does it even work in Linux? From this thread on a Asrock board with a similar configuration I gather it's possible to set up this resolution with YCbCr420 in Windows.

       

      Thanks in advance.
