2nd Monitor.

I recently bought a 2nd monitor and I connected it to my PC but there is a problem. The problem is that windows 10 has detected it and I have extended my display but my 2nd monitor wont display anything it just stays black. Can someone help me please.

 

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.]
