    Yes, you read correctly. I want to force a refresh rate of 30Hz on a normal FullHD or WQHD monitor.

    Reason is that I want to go for a bigger monitor and I'd prefer 4k at this point in time (running FullHD in HiDPI). With the mini only allowing 30Hz@4k, I'd like to evaluate 30Hz for myself to decide whether it would be acceptable or whether I'd have to contemplate a different setup.

    The only available refresh rate in OSX is 60Hz (and 50Hz, when monitor is connected via HDMI). I'd prefer not to buy SwitchResX just for this one-time evaluation.

    Any ideas?
