Windows 11 cannot detect second monitor.

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.

    I am a GenX who had the same issue. My MSI laptop used to detect and display on an additional monitor until it did not. I tried everything I found online: update my display adapters, tried Window "P", tried multiple connections (USB/HDMI) and more. Nothing worked. Until a young IT person where I teach figured out what it was. My laptop is a gaming laptop (no gaming on my part, only AutoCAD and 3D rendering programs that need a lot of processing power and really good graphic card). My laptop has actually 2 display adapters - which I was not aware of: one "regular" called AMD Radeon(TM) Graphics and one I assume for "gaming mode" called AMD Radeon RX 6700M (you can find your display adapter(s) in "Device Manager" then "Display Adapter". My laptop went for a screen replacement at the manufacturer and I suspect they changed the setting to gaming mode without telling me. Unless I changed inadvertently to a gaming mode... I had noticed since I got the laptop back that the laptop fans were running on turbo mode most of the time (with very poor battery life), that I could not put my laptop to sleep, and that my AutoCAD program asked me a weird question about my display resolution the first time I used it after getting it back. I had assumed the laptop was just getting old. All the IT person did was disable the gaming display adapter, and my laptop was back to normal, with sleep mode unable, detecting another monitor and running at normal fan speed with now much better battery life. I felt stupid for not knowing that, so I hope my GenX misadventure will help others.

    hi, My 2nd screen was working for over a year. today it stopped working. tried to delete and restart and uninstall restart and still not displaying duplicate screen. when I press window key + P and select duplicate or extend. Then in settings display select detect and says "we didn´t find another display". After when I open again window key + P, the window is always on PC screen only instead of duplicate. That seems to be the problem but I can´t get it to stay on duplicate selection. any ideas? thanks for helping

    Hi, I tried hard reset - hold power button on your PC till turn off. This simple solution worked.

    Yes, the exact same issues, worked on W-10 computer but not on W-11 system. Frustrating.

    Will not Recognize second monitor, tried all the same fixes you did, still nothing.

    Microsoft needs to fix it and stop offering only run-arounds that dont work.. !
