Fix display resulution

[watch]

Hey I have a similar problem as here discribed:

Resulution 480p after power on

Hi, please help, after power on TV and my Mecool kiii pro with coreelec, kodi is in 480p. After reboot box with tv power on, kodi boot in normal resulution 4K. Why kodi in first boot change resulution to 480p? How fix it?

I disconnect my box and the tv from the grid after using it for just once a week. When I turn it both back on again the box seems to be back faster than my tv so the box switch to a lower resulution than 1080p as I set it up in the settings.
Delaying the startup process of the box as adviced in the old thread is not a propper sulution in my opinion.

My question now is: is it possible to force the system to boot up in 1080p even it can’t detect an output strait away?

Yes, with SSH commands:

fw_setenv hdmimode 1080p50hz
fw_setenv outputmode 1080p50hz

or

fw_setenv hdmimode 1080p60hz
fw_setenv outputmode 1080p60hz

I would try a different HDMI cable first.

If your box is Amlogic, turn on Display, then turn on box, and then run cat /sys/class/amhdmitx/amhdmitx0/disp_cap > /storage/.kodi/userdata/disp_cap through SSH.

After this, even when you restart the box during shutdowned Display, Kodi dont loose display’s capabilities memory.

I did this on Amlogic, if your box is Rpi, then you need to store edid through tvservice -d /flash/edid command and then add a few commands to the config.txt.
