All drivers are freshly installed and up to date. Graphics card is barely a year old and all cables also checked. The monitor thats not detected does work also.

Everything worked until 2days ago when windows updated and now windows does not detect the second display.

Please help thank you.

Hello ScrP, welcome to the Microsoft community, I'll be happy to help you today;

I understand that after an update the second monitor is not detected;

What exactly is the model and manufacturer of your graphics card?

Are you using an HDMI cable to connect the second monitor?

Are you using a laptop or desktop?

Before answering the question, I suggest you try to force the detection of the second monitor;

Press Windows key + i and go to System;

Click Display;

Scroll down to Multiple screens, click Detect;

Then press the keys together: Windows key + P and select the Extend option;

Verify that the second monitor is detected;

See you soon!

    I tried everything you mentioned but it just shows (Didn't detect another display).

    I plugged the VGA cord from my Monitor to the TV

    I plugged the HDMI cord from my monitor to my PC

    I plugged the HDMI cord from my TV to my PC

    That might be the wrong way to do it but I don't know how else to do it.

    Hi - I actually got the second monitor to detect and come back quicker this time, for what ever reason.

    (a few times After I wrote in this forum)

    I only had to unplug the USB-C to VGA about 5 times with warm reboots, then a cold reboot (shutdown to ground).

    In the past I have done several other things when this happened. Never sure which thing fixed it. Sometimes

    unplugging the VGA plug from monitor to the USBC-VGA adaptor.

    Not an exact science here.

    I followed the instructions, but it does not stay on extend. I click extend, but nothing happens. I clicked Detect again and it is still not able to find another display, hit windows and P again and its back on PC screen only.
