HDMI output not working

[Flavor]

Have you tried multiple monitor/TVs? We set up the config to work with the majority of displays, but we do run into some that it doesn't like from time to time.

As far as config.txt goes:
The first thing I might try changing is this line
hdmi_drive=1 #Normal DVI mode (No sound) (2 for HDMI with sound)
to
hdmi_drive=2 #Normal DVI mode (No sound) (2 for HDMI with sound)

Or you could just comment it out like
#hdmi_drive=1 #Normal DVI mode (No sound) (2 for HDMI with sound)


The next one I'd try is changing
HDMI_FORCE_MODE=1
hdmi_group=2
hdmi_mode=16
to
#HDMI_FORCE_MODE=1
#hdmi_group=2
#hdmi_mode=16

FYI, after you change /boot/config.txt, you need to reboot (with the HDMI connected to your display) to see any change in the result.
