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!

    Same thing here. My laptop, asus rog zephyrus g14, does not detect other monitors, though it used to have no problems with it. The cable and the second monitor are fine, I checked them with another laptop. I thought it's about updates or drivers, but till now nothing helps. I already agree it might be because of windows 11, I cried for days trying to make this laptop work properly at the beginning, wanted to give it back to the seller. The hardware is good, but the soft is just unbearable. Next time I'm buying mac just to not stress so much. But till then I am left with no second monitor. I am extremely upset and disappointed.

    Hi

    This occurred to me today.

    I shut down this afternoon and went out. When I came back home, Windows is not sending a signal to the external monitor.

    There was no auto-update as I was shutting down this afternoon.

    My Setup.

    Lenovo YOGA Laptop with Intel iRISxe Graphics

    External Screen Dell 24"

    Out of laptop via USB-C. Into the Screen using HDMI.

    The screen detects the HDMI cable and says there is no signal.

    The laptop doesn't detect the external device.

    I have tried everything you suggested above - including Windows+P, and click extend. Doesn't work.

    Have removed the graphics card and reinstalled the graphics card. What else can I do?
