--- Comment #15 from Michael Mounteney <gate03 at landcroft.com> ---
So everything works as intended but the monitor no longer switches to the
highest resolution.

It seems that the problem is that the EDID is reporting single-link, which is
relevant to DVI-D, but my connection is HDMI.  Doesn't it make sense to ignore
any single-link/dual-link information with an HDMI connection?  Possibly with
CONFIG_HDMI_IGNORE_LINK_ARITY ?

If you aren't prepared to do this, could you at least supply an indication of
where to hack the source;  otherwise I am stuck on kernel 4.7.4 for ever, or
for at least as I continue to use Linux.
