<pre>I'm not sure, but is possible the issue were fixed between revisions 43 and 45
of ubuntu kernel 4.15.
Before upgrading the kernel, we reached a solution:
- Using EDID emulators, getting xrandr showing both DisplayPort outputting 4k
- Dumping the EDID to a file
- Quitting emulators, conecting DisplayPorts normally with EDID firmware forced
to previously generated file.
Will attach our working EDID file.</pre>
