how to work without EDID ?

  • If I will activate CEC with my wetek play + AVR + TV, then avr and TV will switch on after wetek load. And resolution from wetek will be not correct 720p) because wetek couldn't read edid from TV and use 720p as default resolution. How to write in any config files that the default resolution should be 1080p@50 Hz ?


  • I have a similar problem but the link is dead. Where could I find this hack and does it work with Krypton builds?

    add the following line to autostart.sh

    mount -o bind /storage/.config/disp_cap /sys/class/amhdmitx/amhdmitx0/disp_cap

    then create a new blank file /storage/.config/disp_cap containing whichever of the following resolutions you want

    480i60hz
    480p60hz
    576i50hz
    576p50hz
    720p60hz
    1080i60hz
    1080p60hz
    720p50hz
    1080i50hz
    1080p30hz
    1080p50hz
    1080p25hz
    1080p24hz
    2160p30hz
    2160p25hz
    2160p24hz
    2160p50hz420
    2160p60hz420

    Mine just has two resolutions in as below :

    1080p50hz
    1080p24hz

    Not sure if it works in Krypton as I've not tested yet

  • Thank you very much kszaq and ukdaveuk! I used all the lines that the TV would announce when live before the box boots and it works beautifully.

    But a question arises: what about the fractional refresh rates? I know that they don't properly work as of yet in Krypton, but shouldn't they be broadcast by the TV in order to allow Kodi to change to them when this becomes possible? Your comprehensive list also does not include them.

    EDIT: For others that might arrive here to fix similar problems: note that the zip from kszaq includes lines like "1080p" without a refresh rate (meaning @60hz). Those don't work on my A95x (S905X), but I had already found out before with "echo 1080p > /sys/class/display/mode". On my box at least I have to include the refresh rate in every resolution, just as in the list by ukdaveuk above.

  • juramusger The ZIP is for S805 and it contains "old style" disp_cap. This means that you need to change "1080p" to "1080p60hz" and "720p" to "720p60hz". I forgot to mention this.

    Fractional refresh rates are set automatically on Amlogic when needed. E.g. when you play 23.976fps video and have 24Hz refresh rate set, the driver will automatically switch to 23.976Hz.

    yes, I automatically added this in my disp_cap as I already knew about the "new style" from trial and error. then 5 minutes after posting the success I thought about it and edited my post so others might find the info more easily.

    thank you for the answer concerning fractional refresh rates!
