    From the splitter, one hdmi cable is connected to the TV and the other to the AVR.

    In my case, all is working with masking pin 15 and 17.

    I tried an hdmi cable with cut wire of pin 15 and it also works.



    The only problem of this solution is the long hdmi handshake (about 10 seconds) when starting the movie.


    I have an Onkyo TX-SR606 AVR and this splitter

    Your problem is similar to mine.

    New TV, old AVR and HDMI splitter


    You can try to do this with a hdmi cable from AVR to the projector.

    I suppose there are more users who by buying a new TV keep their old AVR. If they use HDMI splitter in combination with a new TV and older AVR certainly have a problem with HDR. Copying the disp_cap file to /storage/.code/userdata/ solves the problem with TV resolution, but not the HDR. I think that copying hdr_cap in /storage/.kodi/userdata/ and processing it we can solve the problem of HDR. Currently, I solved this problem by blocking the pin 15 on the cable from the splitter to the AVR.

    I have these hdmi splitter. Even hdr goes through it and of course DTS-HD or TrueHD audio to AVR.

    I resolved problem putting a strip of tape over HDMI pins 15 and 17.



    On the picture you can see example of tape strip over pin 19.



    I would prefer software solution.

    Maybe something like disp_cap in /storage/.kodi/userdata but for edid and hdr_cap.

    I have S905x box connected to an HDMI splitter. On the other side I have connected TV and AVR. When TV is on and AVR is off I can watch HDR content. When I switch AVR on then HDR is not even coming out from the box. I already done "cat /sys/class/amhdmitx/amhdmitx0/disp_cap > /storage/.kodi/userdata/disp_cap" as kszaq recommended and solved problems with UHD resolutions.


    Enclosed files "edid", "hdr_cap" and "dc_cap" before and after turning AVR on.

    cat.txt


    Any idea of how to resolve this issue?
