Windows 11 with 3 monitors resolution problem

We have several pc's with multiple displays. All should have a scale of 100% & resolution of 1920 x 1080. Since we changed our desktops from W10 to W11, there is a resolution detection problem of one of the 2 (identical ) monitors. 

After a reboot one of the 2 screens has suddenly a resolution of 1440 x 900, AND Windows doesn't offer higher resolution then 1440 x 900 for this monitor.
It can also happen when we turn of a monitor.
Sometimes we get it back after resconnecting and rebooting .
In windows 10 we didn't had that problem. 
Anyone who has a solution for this problem? Microsoft?

Kind regards

KD

    Ensure that Windows 11 is fully updated, as Microsoft often releases patches that could improve multi-monitor support.

    1. Check monitor connections:
    Make sure all monitors are properly connected to the graphics card (HDMI, DisplayPort, DVI, etc.).
    Check for damaged cables and try replacing them.
    2. Update the graphics card driver:
    Open “Device Manager” and expand “Display Adapters”.
    Right-click on the graphics card and select “Update Driver”.
    Visit the official website of the graphics card manufacturer (e.g. NVIDIA, AMD, Intel) to download and install the latest driver.
    3. Adjust the monitor resolution:
    Right-click on your desktop and select “Display Settings”.
    In the “Display” tab, select each monitor and set the appropriate resolution.
    Make sure the “Zoom and Layout” settings are consistent.
    4. Rearrange the monitors:
    In the Display Settings, drag the monitor icons to match the actual arrangement order.
    Click the “Identify” button to confirm the number of each monitor.
    5. Use the graphics card control panel:
    Open a graphics card control panel (e.g. NVIDIA Control Panel, AMD Radeon Settings, Intel Graphics Card Control Panel).
    In Multi-Monitor Settings, adjust the resolution, refresh rate, and alignment.
    6. Check the monitor refresh rate:
    In “Display Settings”, select each monitor and click “Advanced Display Settings”.
    Make sure the refresh rate is set to the recommended value for your monitor.
    7. Disable unnecessary monitors:
    If the problem only occurs on a specific monitor, try disabling that monitor and check if the other monitors are working properly.
    8. Use clean boot:
    Press Win + R, type msconfig, and enter.
    In the “Services” tab, check “Hide all Microsoft services” and click “Disable all”.
    In the “Startup” tab, click “Open Task Manager” and disable all startup items.
    Restart your computer and check if the problem is solved.
