<pre>I just found something. My monitor - Dell U2413 has a setting for toggling
DisplayPort 1.2. It was enabled until now. When I disable that setting, tty
starts working!
My cable is supposed to support DP 1.2 and be Vesa compliant. It's Accel
UltraAV DP 1.2 cable.
I hope this can help narrow down the problem.</pre>
