Unfortunately EDID doesn't seem to be making it through. /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/edid is empty so I tried read-edid, but it reported "Monitor and video card combination does not support DDC1/2 transfers".  EDID was present using VGA-DVI so the TV does support EDID. (Although it didn't actually support the modes it claimed to when it determined it was connected to a PC!)

I've attached dmidecode output in case it helps.
