For testing purposes, disconnect all USB cabling from the U2518D. All USB devices should then plugged directly into the two PC's.
The only cabling connected to the U2518D should be power and the two video cables = PC #1 GTX 1080 DP out port --> U2518D DP to mDP cable --> U2518D mDP in port PC #2 Intel HDMI out port --> HDMI to HDMI cable --> U2518D HDMI in port
In the U2518D OSD (On Screen Display) Menu- Input Source. Go to Auto Select. Change it to Off. Exit the Menu.
Now, with both PC on, test switching back and forth from mDP to HDMI using the Menu- Input Source.
Actually started working normally again (DP + mDP/HDMI). Then after a few hours of idle, the issue came back. The only way I was able to wake the monitor was by simply unplugging the mDP. The quick fix isn't exclusively unplugging either mDP/HDMI/DP -- the monitor wakes when I unplug all but the single cable I want working. Really weird as it was working perfectly before switching. Recently decided to add a Raspberry Pi as a 3rd connection (HDMI) -- though I doubt it's culprit (unplugged in any case).
Another issue that recently came up is that the monitor doesn't power down as usual. It blanks out when it's expected to power down (via Windows power options), but it doesn't actually power down.
I've uninstalled the Dell software just in case it might be causing conflict, but I guess not. What's next? Make a video and call Dell for warranty support? Would it be worth a shot to try and reflash the monitor firmware? It's already using the latest (M2T103), but just in case of a possible corruption somehow?
Before contacting Support, attempting to install M2T103 over itself is a good idea. Was this purchased directly from Dell? When was it purchased? What is the 20 digit S/N?
I haven't replied back sooner because the monitor was working fine for a few days, and now I'm stuck with the same issues. I half solved the monitor blanking out issue (I think) by locking Windows on the unused computer. I think the monitor was auto-switching when the computer would wake up (not from sleep, just a Windows monitor wake), despite auto-switching set to off on the monitor. But my biggest issue right now is that when I switch from DP to mDP, the monitor doesn't detect a signal and blanks out leaving me unable to switch back to any other input until I unplug the DP cable from the monitor.
I hate doing exchanges, but if this issue merits an exchange I'd like to go through with it. I purchased the monitor directly from the Dell in May. My service tag is
