No luck, its like kms driver has its own logic - ignoring all setup before

And again same.

But i got more info,

If i disable dtoverlay in distroconfig boot logo of libreekec looks perfect, but libreekec wont start

It seems that vc4-fkms-v3d is messing with resolution somehow

Now not even the rainbow screen is in sync

Tried new sdcard just in case, no luck

Same,

I would say its booting now in 4:3 (rainbow screen) as before it would boot in 16:9

but Kodi still 480p so its garbled...

It looks like libreelec is loading standard HDMI edid or something, kodi available resolutions are from 480p to 1080p 60

No luck, same problem - libreelec ignores it and turns on to 1920x1080@60, it does not have the pal resolution in its list, just standard hdmi resolutions

I changed it to 640x480 but its still out of sync, since its 480p60

These are tvservice outputs

LibreELECcrt:~ # tvservice -s

state 0xa [HDMI CUSTOM RGB full 4:3], 640x480 @ 60.00Hz, progressive

LibreELECcrt:~ # tvservice -l

1 attached device(s), display ID's are :

Display Number 2, type HDMI 0

This command switched to the correct mode (720x576i), but kodi is mishapen and it reverts to its standard resolution after restart...

LibreELECcrt:~ # tvservice -e CEA\ 26

Powering on HDMI with explicit settings (CEA mode 26)

Well, this is the image I've been using:

LibreELEC-RPi4.arm-9.2.7.img

So it was 9.2.7 all the time...

Also tried now

video=HDMI-A-1:320x240@60

and even that does not show correctly.

On rpi 3b it all works fine....

I tried it already, but cant figure params for 576i 50hz pal mode.

Tried 720x576@50i

But it wont sync…

Thanks

Hi all,

I have been using rpi3b with these options for a while on my SDTV and it worked beautifully.

Tried to update to rpi4 - no luck. It displays correct resolution for rainbow boot screen but librelec forces 1920x1080@60hz for some reason.

I've attached config.txt (form rpi4, but I tried the same with latest libreelec on rpi3b and it works fine)

Is librelec overriding edid or something? Any help is appreciated.

These are my custom options

hdmi_ignore_cec=1

hdmi_drive=1

hdmi_force_hotplug=1

hdmi_ignore_hotplug=0

hdmi_ignore_edid=0xa5000080

hdmi_group=1

# 320x240 - works rpi3

# hdmi_mode=9

# 576i - works rpi3

# hdmi_mode=22

# 576i quad - works rpi3

hdmi_mode=26

# 576i 100hz

# hdmi_mode=45

# 576i 200hz

# hdmi_mode=55

# 1080i

# hdmi_mode=39

disable_overscan=1

framebuffer_priority=2

hdmi_force_mode=1

hdmi_blanking=1

hdmi_pixel_encoding=1

hdmi_ignore_edid_audio=1

config_hdmi_bo*ost=6

sdtv_mode=2

sdtv_aspect=3

Thanks!
