Did I just buy a crappy HDMI to DVI adapter? Is my monitor too old? It's from, like, 2009, but it has a dvi-d port. The HDMI works fine through all this... I can pull the plug, put it in my TV and RPi displays in safe mode.
RPi works, I can SSH to it, view and edit /boot/config.txt. Can run tvservice and extract edid information which I can post tomorrow if necessary. EDID info pulls model number and modes correctly from what I can tell.
I have changed HDMI_safe=1 and commented everything else out. Still no DVI display from monitor.
Anything else suspicious before I go buy a new adapter?
