This message appeared on my GN246HL recently, even if i've been using that same cable for years. Plus the message does NOT appear when i first boot my pc, but only if it goes in sleep mode and then gets turned on again (restarting the pc makes the message disappear temporarily). The message only appears when using >60hz settings. I recently had a windows update (i was and still am on windows 10, just a more recent version) that may be the cause (i surely didn't have this problem before, i don't know if it came up right after the update or some time later)

    Hello and welcome to the Acer Community.

    It might be a "glitch" with the monitor or potentially a driver issue. Resetting the monitor to back to default settings might resolve the issue. Is the computer an Acer too?

    Hi, I've tried both resetting the monitor and updating my gpu drivers (nvidia gtx 750) but to no avail. No my pc is an old desktop.

    Then testing the monitor on another system might be best option.

    The "Incorrect cable" error on your Acer GN246HL when trying to use a refresh rate higher than 60Hz after a Windows update is likely due to an outdated or incompatible cable, or potentially a driver issue. To fix this, ensure you're using a dual-link DVI cable, or consider an active DVI to DisplayPort adapter if you're using a different connection type, and verify that your graphics drivers are up to date.
    Here's a breakdown of the potential causes and solutions:

    1. Cable Type:
    Dual-link DVI:
    The Acer GN246HL requires a dual-link DVI cable to support refresh rates higher than 60Hz. If you're using a single-link DVI cable or an adapter, it won't be able to carry the necessary bandwidth.
    Active Adapter:
    If you're connecting via HDMI or DisplayPort, you may need an active DVI to DisplayPort adapter. Passive adapters, which are cheaper, will not work for higher refresh rates
    2. Driver Issues:
    Outdated Drivers:
    An outdated or corrupted graphics driver can also cause refresh rate problems. Ensure you have the latest drivers installed for your graphics card.
    Reinstalling Drivers:
    If updating doesn't help, try uninstalling and reinstalling your graphics drivers, says the Microsoft Community.
    3. Windows Settings:
    Check Display Settings:
    Go to Settings > System > Display > Advanced display settings. Select your monitor, and under "Refresh rate," ensure the desired 144Hz (or other) option is selected.
    List Modes:
    You can also click "Display adapter properties" and then "List modes" to see all supported refresh rates for your monitor and graphics card.
