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.

1. Disable and re-enable the graphics card
   • Press the Windows key + X and select Device Manager.
   • Expand the "Display Adapters" section.
   • Right-click on the graphics card (e.g., NVIDIA GeForce) and select "Disable device".
   • Wait for 10 seconds and then enable it again.

Answer 5

I have tried everything suggested in this thread—down to a new cable. The monitor is on, but the laptop can show Windows + P shows, which I can extend (after the uninstall/restart). But when I go into the display settings, it still says it can not detect it.

Is there anything else I can try?
