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!

    Microsoft is forcing me to go Apple and I hate Apple. What I hate more is how unstable Win 11 Pro is. It is a constant issue that every time I restart, virtually every time, my monitor setting get reset to default and my external monitor cannot be found. Detect Display is as useless as mammary glands on a boar. Projection settings is useless too. I have been using windows since it was first commercially available. One would figure that Microsoft would have discovered stable platforms by now.
