    Secondary display issues - iMac running Windows 10 on bootcamp


    I'm running Windows 10 on an iMac 27" using Bootcamp. I have a secondary display attached to the iMac.
    The secondary display is a Dell Monitor https://www.dell.com/ae/business/p/d...17h-monitor/pd


    The problem:
    The secondary display is recognized when the device boots up. I have the display configuration set to

    "Extend this display"

    The iMac is configured as "set this as the main display".

    While the iMac has a screen resolution of 5120x2880, the secondary display has a maximum resolution of 1920x1080, because of which moving across both screens is not smooth.

    This is evident in the video below which i took as a screen record.

    I can live with this discrepancy (It is smooth when running on Mac OS X with no such issues). There are however a couple of issues

    1. My display settings are not remembered if i close the Settings>>Display window and open again. "Extend this display", although previously checked is now unchecked. This is an intermittent problem and does not always happen.

    2. If i put the computer in sleep mode and wake up again, the secondary display is not recognized at all. The secondary display remains just a black screen. The Settings>>Display window does not show the secondary display as well. Unless i restart the computer, the secondary display does not get recognized.

    How can i 'fix' these issues ? Any help is appreciated. Thank you

    You really need to be on the Apple Support forums. You are using Apple's hardware to run Windows in Bootcamp and only the Apple forums can help you out. Moving between two displays at different resolutions is going to be horrid. Put both at the same resolution and you should have no problems after that.

    If im honest, i have tried the Apple forums. It is a recurring problem for other Apple users as well for which not many have a solution. i wanted to try here to see if anyone else might have an alternative solution. Yes, i agree with you. putting both in the same resolution helps with the screen transition, but if i put the computer in sleep mode, i still cannot get the second monitor to wake up . Either way, thank you for trying.
