Windows 10: Why my 2nd monitor only displays if my laptop is close?

Hi;I have 2 external monitors connect to my PC via a docking station. I can get one of the monitors to work. Only when I close my PC will both external monitors work. I use a collgues PC to test the monitors and everything work perfectly. I have check that extended function is on. When going into settings-> display I can see PC has 3 displays but still the 2nd monitor will not work. Only 1 monitor and my PC display.

Color Display on 2nd monitor

I am using Windows 10 on a Dell laptop with a 2nd monitor which has been working fine. For some unknown reason I have suddenly lost the full color range on the 2nd monitor. I don't know if I have changed some setting by accident or what. I have tried
resetting the defaults but that didn't change anything on the 2nd monitor. The primary screen on the laptop continues to work fine. Any suggestions what needs to be done to restore the full color range on monitor #2?

 

Cannot get non-connected 2nd Monitor screen moved to Laptop Screen?

This is kind of hard to explain in a Subject line.

I have a USB Docking station set up at home with 2 large monitors, keyboard, printers, etc. connected to the docking station -- all plugged into a Laptop, whose screen is also active. Works great - Window's magic, I guess. I also have several programs
set up to come up (screen display) on the 2nd or 3rd Monitor screens when they are loaded.

My problem is, if (when) I just unplug the USB cable to the Docking station and take my Laptop over to a friends house, when I load one of the programs that comes up on one of my monitors, the program comes up and loads correctly (i.e. shows up on the taskbar
as running) - but the display is someplace in outer space because the 2nd (or 3rd) monitor is not there.

And for the life of me, I cannot figure out how to get the screen display (which the program apparently thinks is being correctly displayed on my 2nd monitor) moved over to my Laptop screen.

DETECT in the Settings\Display screen does not find any extra monitors (because they are not there) and the Extend and other options under the Windows-P Project option does not seem to help -- and many of the suggested fixes document steps involving options
that are apparently for older versions of Windows because many of the steps don't match the options on my version of Windows, which is the very latest Windows 10 update.

Surely there must be a simple way to fix this, but I have spent oven an hour trying to figure it out.

[P.S. I finally got the screen from the 2nd monitor to display on my Laptop screen, BUT I HAVE NO IDEA WHAT I DID TO MAKE THAT HAPPEN.]

2nd display not detected when Laptop Lid is Closed.

Hi,

I am using an external monitor together with my laptop and I usually will extend the display to the external monitor. Usually when I want to watch videos or anything, I will bring the specific window to the extended display and close my laptop lid, and the
computer will still recognise that there are 2 displays . But recently when I close my laptop lid, the computer does not recognise the multiple displays (only recognises my external display), and merges all the windows / the main screen to the external monitor.
Only when I open my laptop lid then the computer will extend the displays. I've tried setting it to "Do Nothing" when I close the lid in the power settings, but it is still the same.

Anyone can help with this problem? Thanks.
