I wonder the same; I'm looking to split an Output as two Monitors, and
then rotate one of the Monitors. I am using an active splitter, like
Jack is w/ the Matrox Dual Head 2 Go devices (I'm using a Sunix DPD2001,
with DisplayPort Multi-Stream Transport disabled).
I ran into issues trying to do setup multiple Monitors for an Output,
and sent a mail to the list in September 2016; Aaron Plattner from
NVIDIA responded, noting about the "ConnectionNumber" property from the
xrandr --prop command. The Intel hardware I'm using (Intel Skylake;
Iris Pro Graphics P580 [8086:193d] (rev 09).
The thread can be viewed here:
I had to give up at the time and still haven't had a chance to poke this
again. I have a feeling this isn't supported, but I couldn't find
anything in the protocol/extension specifications stating so. In fact,
the specs imply that it _is_ indeed possible. Perhaps only certain
drivers provide this level of support?
Jack, let me know if you figure this out, please and thank you!
