    Display changing color on wake from sleep


    Hello all! I'm new to the forum and hope you gurus will be able to help me sort out what's going on with my laptop. Since the last update I've been having an odd issue upon wake from sleep. The screen is dimmed a bit and is a more muted yellowish hue. When I open Settings>>Display the screen immediately returns to the bright and true colors it should have. Sometimes I have to do that twice, but then after that the display stays bright and true color until the next wake from sleep.

    Night Light toggle is set to "Off."

    I am on a Lenovo ThinkPad T440s, FHD, running Win10 2004 (19041.508). This behavior has started only since the last update. I thought it might be a driver issue but driver rollback is not available for the display.

    When I look at the display properties, the display is now recognized as a "Generic PnP Monitor." I can't remember what used to be there, but it wasn't generic. Everything else seems to be working just fine, resolution is good, brightness is good, but this wake from sleep color change is weird.

    Ideas?

    Thank you for your help!

    P.S., I asked a couple of my students, but they didn't seem to have an answer either.

    :)

  3. computer wake-up after sleep

    Did all the steps exactly as shown above and "Allow this device to wake the computer" was already selected.

    I think you might have miss-understood the problem. It appears that the computer is waking up, but it doesn't re-connect to my display. I have to turn off the display and turn it back on to get my display to to re-connect. This was not a problem prior to
    the last Win 10 upgrade.

    wake from sleep issue in windows 10

    Hi,

    Thank you for posting your reply. Apologize for the delay in response.

    I suggest you to check which devices are configured to wake up the computer from sleep by following the steps below:

    • Right click on Start icon and select Command Prompt (Admin).
    • Type the command line below:
    Powercfg /devicequery wake_armed

    3. Check if the devices (Keyboard, Mouse, Ethernet cable) are listed.

    If the system is not going to sleep and going to Hybernate, the only option to wake up is to press the Power button.

    Hope the information is helpful.
