My organization has purchased a number of M700 Tiny units, So far there have been a few minor issues but nothing spectacular. But one issue we keep coming across is a dual monitor problem on machines with only one monitor connected.
The problem is the user comes in and turns on the machine and gets past the HDD password we have setup and then gets into windows and all they see is a black screen. Ifthey move the mouse to the screen they can see it. We get a call about a black screen and nothing on it. We go to the system and find it is plugged in and all is good. Windows 10 is acting like it has dual monitors setup but the unit has never had a second screen connected to it. The M700 has dual Display Ports on it. I am finding this issue on either of the two ports but usually the one not close to the power adapter. If the monitor is plugged into the one mentioned I moved it to the one closest to the power and that seems to resolve the issue for most. Every now and the problem is with the one closest to the power adapter.
I have run all the system updates from Lenovo System Updater and still find this randomly happens. I am guessing this is a windows 10 issue. The machines do not yet have the anniversary update. That is something we are planning on rolling out soon. Does anyone have any suggestiongs for this type of problem? Has any one else experienced this?

The monitors are attached via DP (DP to DP)? What size and what res.? You don't mention the BIOS version and date.

Are they running the OS as received from Lenovo, or did these system have an image installed on them? If so, did the image PC have dual monitors?

There was a significant enhancement to the Display capability with Win 10, and it's possible that the Anniversary Update can correct a problem there.

Same issue w/multiple M700's purchased over the last 2-3 months (5-2017). Running our image of Win10E build 1511. If only one monitor is connected sometimes it'll work - or not.
Thankfully, most our users are using DUAL monitors, which doesn't seem to be an issue.
All are connected via DP to DVI or DP to VGA adapter - doesn't matter.
We're coming from a Wyse and HP TC enviroment where most users had dual monitors w/OUT this issue using Windows 7 Embedded.
Anyone found a fix?
