Windows 10: Windows won't detect my monitor

I use my laptop connected to an external monitor. Today I got home, plugged in my laptop to find that it wouldn't detect my external monitor. I've no idea why this is happening as 2 days ago it was working fine, same cable and everything. I use a HDMI switcher but plugging directly into my monitor still doesn't work. My Xbox One and Nintendo Switch both work fine so I believe this is software related. I have already tried updating, rolling back and reinstalling my drivers but that hasn't helped.

Appreciate any help

Thanks!

Windows 10 Not Detecting 2nd Monitor

this recommendation is useless. I followed every step and the troubleshooter said no problems detected. When I had Windows 8.1 I was able to simply plug in my monitor (HannsG 28") via micro HDMI port and it was able to detect it. But Windows 10 does not detect
my second monitor. The system just does not see it.

 

4870x2 won't display at 1680x1050 at all!

OK. Now I know what ur problem is. Step by step:
1. Go to Catalyst Control Center
2. Click on the word "Graphic" right on top left corner. It will display drop down menu
3. Click on Display monitor and will see the list of monitor at near bottom
4. Right Click the monitor and select "Configure". It will show up the window
5. There will be 3 option to select. Select the middle one and then click on the tab which show the bar with 15%.
6. Drag the bar to max, and the screen will stretch to the native resolution 1680x1050.
7. Also click the tab with showing RGB drop down list and select the last one (it will change to image quality for pc).
That's it. Good Luck.
