• Can SwitchResX disable a display ?
    At this time, this function is working on Intel Macs with the drawbacks that are mentioned in the following FAQs
    On Apple Silicon Macs, the function doesn't work at all because the underlying function in macOS has been removed.

    On Intel Macs:
    SwitchResX includes a function to remove a display from the System's list of managed display. This means the display in question, once deactivated, will not be visible from the System or from any application. Only SwitchResX will be able to activate the display again.

    To get this option active, open the Preferences application, go in the "Menus" section, select "Enable/Disable displays" and you'll get the option in one of the SwitchResX menus
    Please also note that if you have mirroring enabled, the menu item will NOT show. So be also sure to disable video mirroring.


    There are however some compatibility problems on Yosemite and Mavericks: see this section of the FAQ.
