Dell D6000 Display Port

[AlbanRampon]

Hello P.Cip,

The logs indicate that the DisplayPort link cannot "train". This is a part where the sender and receiver send specific known patterns and, based on error level, decide at which speed they will talk.
This is generally the sign of a bad connection, the link, and different from being unable to read the monitor identification details I initially thought about.

Could it be possible for you to try an alternative DisplayPort cable?
If this doesn't work, we will need to proceed with purchasing a HP Z27i monitor.

Kind regards,
Alban
