    This is a common persistent problem for many types of laptops. Mine is a Dell Alienware . It was NEVER resolved in previous threads, just closed by windows helpBasicly: if you plug an external monitor into your laptop and your laptop goes to sleep, windows doesn't detect the attached monitor when you wake it up, NOR can it find it using search in settings. I'm using the latest updates Win11 home

  2. Problem with Windows 11 (?) detecting external monitors from sleep

    Laptop is Lenovo Yoga running Windows 11 with Intel(R) Iris(R) Xe Graphics driver. All up to date. The laptop is connected to two external monitors via USBC port and HDMI adaptor. The monitors work perfectly when the HDMI adaptor is plugged in, but when the laptop awaked from sleep, only one of the external monitors is detected. To resolve I have to unplug then re-plug in the HDMI adaptor to the laptop (USBC port) and this seems to nudge the laptop to detect both of the monitors. As a consequence, I am unplugging and re-plugging in the HDMI adaptor many times each day.

    When I connect my HP Envy laptop running Windows 10, using the same monitors and HDMI adaptor, there are no such problems. When this laptop wakes from sleep it fires up the two external monitors.

    I don't know if this is a problem with Windows 11, or the graphics driver, or indeed something else I'm missing.

    Any help would be much appreciated as it would be great to get my Lenovo Yoga working as intended.

    thanks

  3. Problem with Windows 11 (?) detecting external monitors from sleep

    Hi, thanks for responding so quickly. I have done all of the above but there is no change.

    Either after rebooting, or waking up form sleep, the second external monitor appears not to be detected.

    And yet, unplugging and replugging the adaptor USBC plug out-of and back in to the laptop USBC port will cause both monitors to be detected OR ALTERNATIVELY (as I have recently discovered) unplugging/replugging any of the monitors from the HDMI adaptor also works. Basically, when I do either of these things, the unplugging causes the laptop to move the display to its own single screen, then replugging seems to launch push to the two external monitors.

    Where as my HP Envy (Windows 10) laptop doesn't seem to require this 'push' to detect both external monitors, my Lenovo (Windows 11) laptop does.

    Any further help would be much appreciated.

    many thanks

    Problem with Windows 11 (?) detecting external monitors from sleep

    Dear Don,I understand that the steps did not resolve the issue;

    When the PC wakes up from sleep mode try pressing the keys: Windows key + P and select the Extend or Duplicate option and check the second monitor instead of disconnecting and connecting the monitor;

    Hope this helps, see you soon!
