OK, so two video cards and

three monitors, yes?

and it works for you, after some tweaks.

You know, at this point I don't care if it's somewhat slow as long as it
works.  I think I'll back up / and /usr tomorrow then install Nouveau to see
if it's any better.

Yeah, it has more than enough outputs.  In fact I moved the HDMI connection
(goes to the L monitor) directly from one to the other.  I haven't been able
to get the GPU fans to come on more than once or twice.  I think either the
card's BIOS or the circuitry that controls the fans may be damaged.  I
thought that if I drove one monitor from the iGPU that would be a workaround
that let me use all three monitors.  But no, the dGPU still overheats if
that monitor's enabled.  So fine, until I either find a fix or replace the
card I'll go back to having them all on the dGPU and disabling one.

I think this monitor actually uses one.
