Troubleshooting • Re: Raspberry Pi 5 not connecting to my 4k Monitor? First time using a pi.

and would like you to make another test by adding below to cmdline.txt

Code:

video=HDMI-A-1:1920x1080M@60D video=HDMI-A-2:3840x2160M@60D vc4.force_hotplug=3

edit: just tested that and there's something weird!

Code:

[   11.783774] vc4-drm axi:gpu: [drm] User-defined mode not supported: "3840x2160": 60 712924 3840 4160 4576 5312 2160 2163 2168 2237 0x20 0x6

added

Code:

hdmi_enable_4kp60=1

to config.txt -> same result

Code:

[   11.723409] vc4-drm axi:gpu: [drm] User-defined mode not supported: "3840x2160": 60 712924 3840 4160 4576 5312 2160 2163 2168 2237 0x20 0x6

EDIT 2:
Tested another DUT with the same line connected to a LG UHD monitor.
Result:
HDMI-1 is active @ UHD
HDMI-2 is XGA, showing there same error message.

--> command shows no effect (again). User should try with a fake EDID instead.
