I think this may be a firmware issue. https://github.com/raspberrypi/firmware/issues/1626

That bug report relates to the fkms driver (which I understand is like the default kms driver but with support for hdmi= settings in config.txt). I can't seem to get either kms using the new syntax in cmdline.txt or fkms using the old syntax in config.txt

The report mentions an older version of the firmware before the bug was introduced. I'm going to see if I can get that installed and try again with the fkms driver.

I am using the HDMI output through a YPbPr adapter. Forgot to mention that. This works for me on 9.2

Hi, I'm currently stuck on 9.2 because 10.0 uses a different way of setting modelines which hasn't been working out for me. My usecase is connecting to a SD CRT TV so I need my Pi to output 640x480i. In 9.2 that's just a matter of setting hdmi_group and hdmi_mode appropriately, but from what I gather, 10.0 requires setting the output in cmdline.txt. I tried adding video=HDMI-1:640x480@60iD to the end of the line in cmdline.txt but no video signal comes across that is recognized by the CRT. Help is appreciated. My pi is a 3B v1.2.
