Force output resolution at bootup

    I'm currently running an x64 v11 nightly but I've come across this since, forever.

    If my LE system crashes or needs a reboot and the home theatre receiver is not turned on, the LE system does not know what resolution to set the output. Since it does not know what resolution to set, it sets no resolution. Many times have I come to fire everything up and I am presented with a blue screen as there is no signal coming into the Onkyo receiver. It forces me to SSH in and re-boot the system when the receiver is turned on so that the display comes back up again.

    I'm hoping there might be a way that I can force the system to output a specific resolution within the LE config somewhere. I've already whitelisted resolutions in Kodi but I suspect the problem starts before Kodi gets started up.

    Yeah, now im at the point where i use the edid of my samsung tv with the integrated panel of a wyse aio thin client.

    i only use the 50 and 60 hz settings (there are more like 24hz, 25hz, 48, etc).

    it was just an experiment but it works!

    (before, on windows i was able to force refresh rate to 50hz with "custom resolution utility (cru)" on the wyse integrated panel too.

    BUT NOW libreelec gui/interface goes black or turns the screen off for a second when the machine "does smthg".

    for example. display is on and when i then hit a key on the keyboard, display goes black for a second.

    another example. display is on and when i then insert usb stick it goes off or turns black for a second.

    Another 1, is the minute of the time changed and screen turned black for a second.

    For me it looks that any kind of change on the libreelec interface causes a "screen resolution" change. :(

    BUT!!! when i playback a video file. screen remains ON till video is stopped.

    Do you have a clue what happens?

    Any way to fix this "screen off" bug?

    I think this is the only last hing that prevents me from using it. :(

    The "News Scroller" (tagesschau24, video source is 720p@50fps) isnt good in the video but in real it runs completely smooth like on a 50hz tv.

    Now i used this edid from a sony device and it seems to work with 50 hz.

    But when i set 1920x1080@60hz with the sony file i get the "black screen for a second" problem again :)

    Would it be possible to create a small edid.bin editor?

    I mean, i think this could be the easiest way to fix problems.

    Then i use the 50hz setting from the sony file and the 60hz from the native original file.

    :)

    OMG OMG OMG

    I made it.

    I used the "original native edid.bin" and then edited it (The CEA Extension was completely missing in the original). :)

    WOOOOW :)

    BTW. This custom edid stuff isnt included in a backup, or?
