Comment # 3 on bug 1038951 from Benny Johnson

One more note, sorry for the spam. Running with the 144Hz monitor on the dock
and one monitor on my laptop seems to be perfectly stable. Running with both on
the dock is still unstable, but a lot less so than with 3 monitors. It runs up
to about 84.90 Hz before turning off when I'm only running two monitors. If I
add my laptop screen, that number goes down to about 50 Hz. So it seems pretty
clear that this is an issue with pushing the dock to its limits.
