    Mid-2010 mini.

    When trying to select a different resolution, many of them give a "display not supported" error. I imagine the error either lies with the graphics card, or with the monitor.

    I've got a plan in mind for testing, however I wanted to see if anyone else has had this problem before.

    Never had that problem, but if I did, I'd just reboot, set the resolution correctly, and forget about it.

    Sounds like a graphic card problem. Good luck.

    I've had that happen with my Air + 24" LED Cinema Display once or twice. For me, it required power cycling the monitor to fix it.

    Power cycled the mini and the display for 5 minutes and it seems to have resolved the issue (for now).

    Very odd.

    Similar thing happened to me on dual displays - one display reverted to 800x600 and the other wasn't detected.

    Power cycled the monitors a few times and all came back to normal.

    Weird.
