--- Comment #8 from Simon <Simon80 at gmail.com> ---
Ah, OK, I had assumed that the cable was fully passive, but if these register
values are coming from the cable, then yes, my position is becoming more and
more tenuous. What is the Windows driver doing, then? I guess it's just taking
risks?

It would be nice if there was an override for this situation that was easier
than manually adding a mode via xrandr, but admittedly, it's a tradeoff there
for some users, and I can no longer argue that it's a bug at this point, more
of a feature request.

If there's anything you're willing to change to improve the situation (in a
"patches welcome" sort of way), please reopen the bug. If you're resolved to
stick with the status quo, then we might as well resolve this as not a bug.
