First of all...please don't recommend I change my power settings or what happens when I close the lid option - those have already been set (see attached pic) and this configuration (described below) has been in use for the past 2 years with no problems. This just started happening - and not after any system update, either.

CONFIGURATION:
Dell Precision 7540 connected to docking station WD19DC via the double USB-C cables.
External monitors are Philips 276Es connected to the docking station via HDMI cables.

In the past, when I powered on my laptop with the lid open, all 3 monitors would power up and my desktop would span all 3.
Laptop display is #1 and externals are #2 & #3 with #2 being set as the "main display"
When I close the laptop the 2 external monitors go black for a few seconds and then come back up and my desktop spans perfectly left to right.
But a few days ago this started happening...
When I close the laptop the 2 external monitors go black for a few seconds and then the left (#2/"main") comes back up but the right (#3) says, "No Video Input".
And the real oddity....if I right click my desktop and select "Display Settings" 2 monitors are shown, but one of them is the laptop screen and not the 2nd external monitor!

What am I missing? Thanks in advance.

Hmmm...after a week of headache I solved the problem...in a weird way, IMO

With monitors #1 (external/main) and a smaller resolution #2 (laptop) showing under display settings I noticed that the setting "Extend Displays" had changed to "Show Only on 1" when I closed the laptop. When I changed it to "Extend These Displays" the lower res #2 display (as shown in the settings window, I mean) changed to a larger display, my 2nd external monitor flashed a few times, and viola...I have my nice big 27" second external monitor back.

It's as if closing the laptop lid made the laptop screen (#3) go away, as expected, but it also made the #2 display unknown and thus changed the setting to only show on #1.

For what it's worth...I tested opening and closing the lid and it's back to functioning as expected.

Hope this helps someone.

Thank you! My extended display setting had changed as well and I wouldn't have caught it without your post!
