Public bug reported:

Hi, on new laptop (thinkpad t450s) I get error message after connecting external monitor:
[drm:intel_dp_complete_link_train [i915]] *ERROR* failed to train DP, aborting

And after that, monitor is turned to sleep mode. Interesting thing is,
that monitor is detected.

I've already reported bug to kernel intel-gfx, so some additional informations can be found there:
