Multihead (3 Montiors) Sabrent USB->HDMI problems

[daidoji70]

That seemed to work to get it listed under xrandr --listproviders

However, screen didn't turn green as it did last time or seem to show
anything (it doesn't display when windows are pulled onto its monitor, just
black).  The difference between this time and last time is it looks like
the EDID had some kind of issue.

Nothing showing in the Xorg.0.log after the hotplug took place.

xrandr --current looks a lot different than last time as well when it was
"kinda" working.
