Sorry for the late response, but your method works Chris, thanks!
The Dell monitor seems to be the 'problem'. Every now and them I got the 'Entering power save mode' message when I turn on the NUC. The exact procedure to fix this is:
Turn off the monitor and disconnect the power cable
Hold the power button 30 seconds
Reconnect the cable and turn on the monitor
Suddenly the mDP and DP ports are recognized with input again. Disconnecting cables is not necessary.
I have a final question and statement about this matter: I think it is not normal to go through this process every month in order to have a functional monitor. Is this are hardware / firmware problem with the Dell minitor and can this be fixed somehow?
There has been no driver update since the problem occured, and a roll back to the previous Intel Iris driver or the initial driver installed by Win10 does not solve the issue.
How do I know if it's an issue with the pc's DisplayPort or monitor DisplayPort if I don't have any other devices with a DisplayPort to test with?
It's weird that I tested both mDP and DP on the monitor, as well as the DPs on the two NUC devices, and none of the combinations seem to work anymore.
"How do I know if it's an issue with the pc's DisplayPort or monitor DisplayPort if I don't have any other devices with a DisplayPort to test with?"
There is no way to know. I would reset them and re-test. If still no go, get exchanges. If the replacements have the same issue, the monitors could not be at fault.
* Turn the computer and monitors off * Disconnect all cables from the monitors including the power cable * Press the monitors power button in for 30 seconds * Reconnect all cabling and re-test
We are not testing on the Intel NUC MiniPC. So no, we are not going to create a firmware flash update just for that MiniPC. Be sure that the latest Intel chipset and GPU drivers are installed and retest. Once working, disable all operating system auto updating to make sure they do not change the drivers. Of course, per the warranty, you may initiate a monitor exchange to get a refurbished replacement P2715Q. Test the replacement before sending any monitor back to Dell. If the replacement does not have the issue, keep it and send us the original. If the replacement has the SAME issue, the monitors were not at fault. Send the replacement back to Dell. Look to the computer operating system drivers or hardware as the culprit.

If it worked in the past, then some driver update to the NUC5i7RYH and D54250WYK are the culprit. Try rolling back the driver updates and re-test.
