Windows 11 cannot detect second monitor.

Question

I just purchased a new laptop that’s running Windows 11. I am trying to set up duel monitors. When I click ‘Detect’ I get ‘We didn’t find another display’.  I am using an HDMI cable to connect the second monitor to my laptop. Both screens work, but they are a mirror image. There’s no way showing to change that setting because the second monitor was not detected. No good.

I set up the second monitor on my main workstation that’s running Windows 10. No problem. Monitor was detected and set as ‘Extended’. Worked fine.

I reviewed everything I could find about this issue. I tried all the suggested fixes. Nothing worked. All available drivers are up to date, etc., etc.

Another thing I tried was hitting the Windows Key + P. That procedure did identify both monitors. In the settings it did show an option to detect the monitors. When I clicked ‘Detect’ it still came back with ‘We didn’t find another display’ I was able to changed the setting to ‘Extended’. I thought I had it working. However, all I get on the second monitor is the background screen, nothing else. No programs show up. I do get the toolbar. But when I click a toolbar link on the main monitor it activates on the second monitor. It’s a mess.

Has anyone had this problem? Is there a fix?

Thank you for any assistance.

Answer 2

hey! Is your 2nd screen working now ? If so, what steps did you followed to make that happen.

Answer 3

No, it is not working still. I tried using regular USB to connect rather than USBC and it still didn’t work.

Answer 4

Thank you for the tips Dhanam, they didn't work though.

Have a similar problem. Used to work with Win 11, then after some windows and Asus updates it doesn't.

Restarted and hard power cycled laptop.

Have uninstalled / deleted and reinstalled graphics driver. Recommended one and latest one a couple of times.

Updated AMD Adrenaline.

Rollback and updated windows at separate times.

Tried the Win P and detect manually.

Used different HDMI cable that works on another PC.

Tried on a couple of different monitors.

Tried a USB C to HDMI that works with another laptop but not this one.

Disabled any gaming settings I could find.

Any others ideas as it still doesn't work?

Thanks

My 2nd monitor is connected to an external brick / MS Surface interface. It supplies power to the Laptop, connects the 2nd display and has various ports and plug-ins on it. Simply disconnecting it from the laptop and reconnecting worked for me.
