Hi all,

I’m trying to install a profile which resulted from calibration, but I get the error message “‘NoneType’ object has no attribute ‘DeviceKey'” when I try to install it. I’ve seen the thread on https://hub.displaycal.net/issue/6099/ and thus reinstalled my display driver, including the necessary reboots, but no luck there. Also reinstalled DisplayCAL. How can I proceed?

Thank you,
Bram

  2. Hello Florian,

    I’m using a NVidia GTX 1060. It is indeed listed in the device manager. My monitors (EIZO 27″) connected via DisplayPort are listed quite generically.

    Thanks,
    Bram

  5. No …profiles.1.log. I’m unsure if you could use the DisplayCAL.log itself, so I’ll just attach it, just to be sure.

  6. There’s something wrong with your system. EnumDisplayDevices should not fail in that way. Please run DisplayCAL-apply-profiles.exe –debug and attach DisplayCAL-apply-profiles.log

    My recommendation would be to completely wipe the display driver and re-install it fresh.

  7. I wiped the display drivers this morning, but that didn’t help.

    Attached you’ll find the logs the debug flag generated.

  10. Nothing that I can do about it. The Windows API calls say that there are no monitors attached to your display adapters.

  11. But there are monitors mentioned at the top? And two adapters have the DISPLAY_DEVICE_ACTIVE flag. Is there anything I can do to make them be reported correctly?

  12. But there are monitors mentioned at the top? And two adapters have the DISPLAY_DEVICE_ACTIVE flag.

    There are no monitor sub-entries under any adapter, and that is a problem. See below how it should look, i.e. at least one adapter should have a monitor connected to it.

    Is there anything I can do to make them be reported correctly?

    Other than trying to figure out what’s wrong with your setup, there’s not much you can do. Reporting the issue to nVidia and Microsoft could be an option. I’m pretty sure if you use Windows color management settings, it’ll also fail, for the same reasons.
