I tested the HDMI output on two external screens (TV and 'standard'
display). Suspending/resuming with external display attached shows no
regressions, as well as sound through HDMI, which is handled by
'drm/i915' IIRC.
To conclude, those 'HDMI output' tests have shown neither new bugs nor
regressions (at least on my system).
