What ho one and all,

New monitor, Dell U2422H. Seems to be working just fine with DP from the Quadro P2000 GPU to the monitor.

But when I turn off the computer or put it into hibernate, a system message appears; No DP signal from Device, followed by Going into Standby.

What does it mean? Can I select something to remove the message as every time I see it, I tend to think something is not right?
