Looks like a standard RandR issue, together with the fact that the card isn't
able to detect EDID from the HDMI connector. Maybe running rhd_conntest as
indicated in the README gets us some more information.

In the meantime, try running xrandr, and check whether there is any mode
detected for the HDMI connectors.

Some modes turn up, but not 1920x1080. What xrandr command should be used to
get
_anything_ onto the HDMI connection? The HDMI on the TV is blank, and all
xrandr
commands I've tried gives zero result.
