Troubleshooting • Re: iRasptek Starter Kit RPI5 8GB No HDMI Output

Added this:
hdmi_force_hotplug=1

I can at least see something but display is all garbage.
It is a Dell 27" 4K monitor that says it can support all lower resolutions.
Mode 16 did not work either.

The following was used:

sudo nano /boot/firmware/config.txt

# Enable DRM VC4 V3D driver
#dtoverlay=vc4-kms-v3d
dtoverlay=vc4-fkms-v3d
#max_framebuffers=2

# Don't have the firmware create an initial video= setting in cmdline.txt.
# Use the kernel's default instead.
disable_fw_kms_setup=1


[all]
hdmi_force_hotplug=1
#hdmi_safe=1
hdmi_group=2
hdmi_mode=82
