U3818DW, HDMI signal cuts out intermittently

We need more data;

* Power reset the monitor
- Disconnect all cables from the U3818DW (including the power cable)
- Press and hold in the power button for 10 seconds. If a capacitive power button, just wait for 30 seconds
- Reconnect the power cable, powered speakers (no headphones), USB upstream cable and a single HDMI to HDMI cable from the computer video card
- Turn the U3818DW on and retest

* To what computer model is the U3818DW attached?
* What operating system is installed on the computer?
* What video card/GPU is installed in the computer?
* What video OUT ports are on the video card/GPU?
* List all U3818DW cables and adapters attached to the computer and the ports they are using and how they are connecting to the U3818DW. For example =

Powered speakers (no headphones) connected to the U3818DW Audio-Line out port
Computer USB out port --> U3818DW USB upstream cable --> U3818DW USB upstream port
Computer video card GTX 1080 HDMI out port --> U3818DW HDMI to HDMI cable --> U3818DW HDMI in port (left)
-or-
Computer video card GTX 1080 HDMI out port --> U3818DW HDMI to HDMI cable --> U3818DW HDMI in port (right)

* For my notes, send me via Private Message the following =
Service tag number
20 digit serial number
A0x revision

How do I private message you with the information? 

In the private message, I only need the Service tag number, 20 digit serial number, A0x revision.

All of the other troubleshooting data should be on this public thread.
