Win 10, new Acer Laptop, Display lost my monitor

Marty Brown · 11-06-2015, 12:53 AM

I had a Dell Inspiron with two external monitors that worked just dandy with Display Link connected to one of the externals. (The Display Link hardware drives one monitor and a cable from the HDMI port drives the other.) That Dell died a quick and painful death and I replaced with a shiny new Acer i7 beauty.

When I installed the Display Link software and plugged in the two monitors, initially, both monitors worked as before. Now, after moving things around and reconnecting, the Display Link monitor works, but is not listed as an active monitor when I try to identify monitors using the Graphics Properties menu, - that monitor is not listed at all. Yet, I can drag things to the monitor and use it. But the monitor is showing as if it is on the far left spot on my desk and it is actually on the far right. My desk setup is such that moving it to the far left is not an option.

Anyone got some ideas on troubleshooting this in Windows 10? I tried following the trouble shooting tips posted here, but they're not up-to-date with Win10... some of the run commands simply do not exist in Microsoft's latest.

Hello Marty,
You might have a corrupted layout.
Would you please try and delete the registry keys detailed in Windows Display Properties "Identify" numbers are incorrect?
First disconnect your additional screens and then reconnect them one by one.
Kind regards,
Alban

Alban - great suggestion! It solved the most aggravating part of the problem - the monitors now "follow the mouse" - that is, they go from east to west as my mouse travels in the same direction.

My graphics options still only identify two monitors - the built in laptop display and the monitor connected by the HDMI cable.. the Display Link monitor does not get it's own identify number, but it functions, and I can drag things to and from it. Not sure why it is not being identified, but the biggest problem is solved.

Thanks very much for your help. I have to admit I was a bit nervous about deleting a registry key, but it all worked out...

Excellent. I understand about deleting registry keys. Like jumping in parachute, it is only scary the first few times...
