<vsyrjala> so that looks like a genuine fail on the sink side

<vsyrjala> <3>[  318.010803] [drm:drm_scdc_set_high_tmds_clock_ratio] *ERROR* Failed to read TMDS config: -6
<vsyrjala> maybe time to reboot the display?
<vsyrjala> i mean yank the power from the display for a bit

--> Display has been unplugged and re-plugged.
