    Cant detect 2nd monitor


    My computer has 1 hdmi port and 2 display ports. The display ports used to work but now cant recognize any monitor as being connected. I've tried many different cables and different monitors. I've updated the drivers and system. I can't figure out what's wrong.Device name Circe Processor AMD Ryzen 5 5600G with Radeon Graphics 3.90 GHz Installed RAM 16.0 GB 15.3 GB usable Device ID CD62C38A-751F-4A06-8D81-5B14A905EC42 Product ID 00342-20766-90427-AAOEM System type 64-bit operating system, x64-based processor Pen and touch Pen support Edition Windows 11 Home Version 22H2 Installed o

    Windows 10 stopped detecting 2nd monitor

    I've restarted the computer (several times), and it's not showing any signs of detecting the 2nd monitor.

    Ever since it stopped working, there's only '1' Display option; clicking 'Detect' in Multiple displays results in the message
    "Didn't detect another display"; the Device Manager only lists one monitor (screenshot below); and it has stopped allowing me to select other projection modes unless I connect to the 2nd monitor wirelessly.

    I'm using an HDMI cable for the 2nd monitor, and have tried both HDMI ports on the monitor unsuccessfully. The monitor models are Dell E2414H and LG 24J4840.

    2nd monitor not being detected

    Received a software update for windows 10. Upon restart my 2nd monitor was no longer working. Went to the display section in Settings and it is not being detected. Pushed the detect button and nothing. How do I get this back. My 2nd monitor is more
    important than any new things in the update.

    Windows 10 Not Detecting 2nd Monitor

    this recommendation is useless. I followed every step and the troubleshooter said no problems detected. When I had Windows 8.1 I was able to simply plug in my monitor (HannsG 28") via micro HDMI port and it was able to detect it. But Windows 10 does not detect
    my second monitor. The system just does not see it.
