PC won't wake from sleep when monitor is connected to it.

[Hardquestions]

My PC won't wake up from sleep sometimes when monitor(Samsung) is connected to it with a DP cable.

After hitting reset Dr.Debug (Asrock MB) will pop a b2 error and will refuse to post.

Even if i turn off or unplug my PC from power b2 error will remain and will refuse to post until i unplug my monitor from my GPU(GTX 1060).

Then i can hotplug my Monitor to my GPU and everything work just fine.

Any solutions?
