Windows 10: Bg image changes to blue when connecting my second monitor

Hey guys, so I just got a new Dell Monitor a few months ago. And started using it right away, unplugging my old monitor. Until I decided to use both of them for multitasking purposes. But I notice that my background image started changing to solid blue when I plug in the second monitor.

It isn't permanently SET TO SOLID BLUE. It's just, when I refresh it, it changes to solid blue. And then refreshing it later on, it changes back to my wallpaper, and then refreshing it later on again, back to solid blue, on and on as long as I have two monitors plugged. Is it because the monitors don't have the same size and resolution? First monitor is 1600:900, 2nd is 1366:768.

I tried several ways to fix it:

1. Checked if Windows 10 has expired (Activation).
2. Updated my GPU drivers.
3. Setting screen resolutions to recommended.

My HDMI connection to my second monitor no longer works

The problem has returned--sort of. Here is the sequence of steps I followed:

1. No display on my second monitor, despite the fact that the HDMI cable was connecting my computer to the monitor.

2. Tried changing the *Start-P settings repeatedly. Nothing. When I set the connection to "extend," my computer clearly thinks that there is a second monitor (all the Windows icons go there--as I have it set to my #1 display), but it is completely dark.

3. Tried multiple restarts. Nothing.

4. Tried connecting it to my older laptop as described above. Worked perfectly.

5. Plugged it back into my current laptop. Works just fine now.

So clearly it's some sort of software or setting issue. Can anyone tell me how to fix this if it comes up again without having to resort to using my old laptop, in case I don't have it around?

 

Changing desktop background when a second monitor is connected/disconnected

Is there a way I can get the computer to automatically change the desktop background when i connect/disconnect the second monitor. As i usually use a dual monitor background but when I disconnect the second monitor the background tries to fit onto the
the first monitor. I'm just hoping there's a way I can get it to automatically change.
