I think I had the same problem as yours.
The solution that worked for me consists of enabling the display in Intel Graphics Command Center.
In the display settings in the Intel Graphics Command Center app, click the three dots of the concerned display and click enable if it's not enabled.

I have the same problem, with the added complication that the "Intel Graphics Command Center" automatically opens on one of the displays which is not visible. That makes it hard to make any adjustments.
After some fiddling with cords, I got it to appear on the laptop monitor, but all displays are listed as 'enabled', but are receiving no input.
Another laptop connected to the same docking station is able to use all displays, is it just this one machine that is not sending information to the external monitors.

The DELL laptop is using Windows 8 while the lenovo is using Windows 10. Previously i was able to duplicate the display from my laptop to the TV screen using a HDMI cable (both laptops could do it). But now it won't duplicate anymore because apparently there's "no signal" even though the tv detected it.

@AltDell Exactly what PC models and monitors do you have? Are all of these disabled: Hibernation, Hybrid Sleep, USB Selective Suspend, and PCI Express Link State Management? The only power management options I know are listed under under Multimedia settings on the same Advanced Settings screen as the options listed above, Have you tried blocking sleep (set it to Never) on all PCs, but allowing all PCs to turn the monitor(s) off after X min of inactivity? Do you need to wake both PCs and all monitors before using the KVM to switch them?

And to add to the questions @DELL-Chris M asked: Are you powering both monitors on before any of the PCs and KVM are powered on? If yes, has either monitor gone to sleep before you power the PCs and KVM, on or when you switch to a different PC? What happens if you swap ports used to connect the different PCs to KVM, and to connect the KVM to the two monitors?

I get this problem often with our docks:
Try the dock in different slots if available.
Try with a different display cable type if you can,
change the display cable for a new one of the same type.
I’d also try CTRL & SHIFT & WINKEY & B
Try powering down the dock then reconnecting.
Check to make sure the monitor is powering on properly.
Uninstall display drivers and reinstall the latest.
Try a windows update & relevant optional drivers if there.

Hi:
A Latitude 5520 “all of a sudden” stopped detecting the 2nd external monitor. Laptop is used with two different docks, one at office and one at home (different models). Both docks have 2 external monitors and all was working well, i.e. both monitors detected when using either dock. Then one day user was working, the screen flashed, and all of a sudden only one of the external monitors was detected. They took it home, connected it to their dock at home and same issue.
Thinking a driver update caused the issue, I reverted the display adapter driver to an older version but same issue.
Any ideas?
Thank you!
