Raspberry Pi 4 HDMI to Component (DAC) garbled image at Emulation Station/Controller Setup Screen

it hasn't the same effect and functionality as on a Pi3

Ah, okay.

So from what I can tell, when Emulation Station starts, the HDMI output changes, somehow, to HDMI CUSTOM RGB lim 16:9, 1920x1080p...from the config.txt specified 480i (ie hdmi_group=1, hdmi_mode=6).

This would lead me to believe, if I could just change the resolution/refresh rate after Emulation Station starts, I could potentially, just reset the video output to the proper setting.

setting the hdmi_timings, or hdmi_cvt settings in the config.txt is just going to get blown away once Emulation Station starts. -Edit- This might not be entirely true.

If the 'tvservice' command is different from the Pi3 to Pi4, do you have any recommendations on what I should look into, as far as commands or configuration changes go?

Do I just need to find the proper arguments for tvservice for the RPi4?

And thanks again!

No, as I said tvservice is not working properly on a Pi4 so don't rely on it for changing resolutions after boot.

@aerosheik I'm with the same issue using the RP4 and I just can see the boot secuence until the RetroPie logo in my CRT TV appears and then I lose signal cos probably Emulation Station has another resolution and is not the same as when the system boots.

Di you fixed or is impossible use RP4 with Retropie in a CRT TV using HDMI to a components transcoder? With a RPZero I can do that wihtout problems just changing the hdmi_mode and group like this:

hdmi_mode=1
hdmi_group=6

But I still can't use my CRT TV under Retropie with a 480i output and idk what can I do right now.
