  • Some dongles are limited to 4K@30. Like this one. You’ll want to double-check the specs of your adapter. They do make DP/HDMI to USB-C cables for what it’s worth. USB-C is a frustrating spec because you can run a lot of different standards over it. Even with cables you’ll want to make sure they’re not running some older spec.

    I just double-checked your monitor’s manual. It looks like HDMI 1 can only do 30hz. Only HDMI 2 and the DP ports support 60hz. Were you trying to connect through HDMI 1?


  • Try plugging the Mac in without a dock.

    A lot of docks out there are DisplayLink based, and you may need to install their driver to get the higher refresh rate.

    Also try switching up which type cable you’re plugging into the dock. Most dock manuals have an esoteric support table based on whether or not you plugged in a DisplayPort or HDMI cable.
