S2719DGF turns on, flashes white, stays solid white

Hello,

I have a S2719DGF.

Post your issue in public and all of the following data
* The issue and all of the troubleshooting you have performed

-It powers on, goes completely white, then black, cycles slowly a few times then finally stays solid white. This happens whether or not the monitor is connected to a computer, and no button presses from the monitor result in any noticeable menu or change of this behavior.

* To what specific PC model is the monitor connected?
* What operating system is running on the PC?
* What specific video card GPU is installed in the PC?
* List all of the video card GPU video out ports
* Then detail how the video card GPU is connected to the monitor like this =
PC GTX 1080 DP out port --> U2718Q DP to mDP cable --> U2718Q mDP in port
PC USB port --> U2718Q USB upstream cable --> U2718Q USB upstream port

-I have it connected to a Dell tower with an HDMI cable but since the monitor does the same thing whether or not it is hooked up to the tower, I am skipping the above info. Additionally, another Dell monitor connected to the tower works just fine.

Is there a series of button presses or a way to reset the monitor without being able to interact with a menu at all?
