No 480i possible at emulationstation/Kodi PI4 400

@lightpixel said in No 480i possible at emulationstation/Kodi PI4 400:

... I also added tvservice -e "CEA 6" in the config.txt, but it it´s not recognized....

That's a command, not a valid config.txt configuration option.
Can you post your current config.txt ? Add code blocks (```) before and after the contents.

# uncomment if you get no picture on HDMI for a default "safe" mode

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus

# uncomment if hdmi display is not detected and composite is being output

#hdmi_mode:0=6

tvservice -e "CEA 6"

hdmi_ignore_edid=0xa5000080

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# no display
config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

# Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
#dtoverlay=vc4-fkms-v3d
#overscan_scale=1

Oh success: I´ve put the

tvservice -e "CEA 6"

in the autostart.sh and now it works...

Your config.txt is wrong - you've commented out the hdmi_mode/hdmi_group options and set hdmi_safe , which will set a fixed resolution. Plus, the tvservice command doesn't go in config.txt.

I suggest you start with a stock config.txt and add at the end:

hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=6
hdmi_ignore_edid=0xa5000080

@lightpixel
and also
config_hdmi_boost=4
doesn't apply to pi4: https://www.raspberrypi.com/documentation/computers/configuration.html#troubleshooting-your-hdmi

@dankcushions
thanks to all but I give it up...
ES starts in 480i now correctly, but Kodi and all other emus switch to 480p when starting.
I´ve here a Pi2scart on my desk which I ´ve ordered some month ago...
Is there any chance to get I work at 480i?
I should only setup the corrcet hdmi timings for 480i... but how?

Don't have a Pi2Scart set-up, so can't comment on that.

i dont know if this is still up-to-date, but after my dissapointing try to connect my Pi4 to a CRT i also wanted to buy a Pi2Scart.
At this point it was not possible to use it without issues, there were problems with the 3,5" headphone-jack, which is used by the Pi2Scart for audio-output.

lightpixel

@sirhenrythe5th
for me sound over the 3,5mm jack is working perfect. And at 240p everthing is working like a charm....

sirhenrythe5th

@lightpixel thanks a lot for info, then this issue seems to be resolved.
Do i understand it right that with this Pi2ScartDevice you also bypass this downclocking of the CPU that the Pi4/OS does when the AV-Out of the Pi4 is used?

lightpixel

@sirhenrythe5th can´t tell exactly, but I did nt notice any performance differences between Pi2scart and composite.
