Video output not working when coreelec is powered on before screen

[bestbudget]

So this is a new issue to me since coreelec 19 arrived.

I guess I tried all version now (including rc).

Till 19.1rc4 I actually mostly got a pink(ish) or sometimes green(ish) picture. After the upgrade today (19.1) the screen stays black (no colours any more ). The black actually comes from my core elec box (s905x3) otherwise my TV would show a no signal sign an turn off automatically.

I don’t remember any problems with coreelec versions prior 19 and have my tv/kodi setup since ever on a socket (and the x96 box is quicker turning on then the TV). It always worked in the past .

Found this snippet here from @crash

Matrix - wrong output mode set on boot

Thx for the workaround, I have the same error on X96 Max+ and an older LG TV connected with hdmi. (celec 9.2.5 and 9.2.7 works without a workaround) I created a gist too for a more general version. (i have 720p60hz resolution) #!/bin/sh # Workaround for CoreELEC 19.x-Matrix green screen error when TV switched on # after the tv box. # # Tested on: # - X96 Max+ (CoreELEC 19.0, 19.1 rc1/rc2) # # Original idea from user dasdreHmomenT on # https://discourse.coreelec.org/t/matrix-wrong-output-mod…

at it seems to does it’s job.

I wonder if coreelec couldn’t just have a setting to “force hdmi output” even if no screen is detected?
