  • Right, so you tried 5 different docking stations? As I said friend, Lenovo and Dell both make DisplayLink docks that are super common for office use.

    The Samsung U28E590 from your screenshot does not support 4k60 on both HDMI ports, and only does 30hz on Port 2 regardless of resolution. So if the Dock is in port 1, and you go USB-C > HDMI on port 2, you are not going to get 4k60, because the monitor can’t do it on anything but port 1.

    If you are using the Apple USB-C > HDMI, you should know it is oldAF any maxes out at 4k30hz (HDMI 1.4). The updated adapter came out in late 2019 and added 4k60 and HDR support (HDMI 2.0).

    In the more likely event that you have random office supplied cables, USB-C to HDMI, a SHOCKING number of them are cheap trash and will not do 4k60, but should do 1080p60… unless plugged into HDMI 2 on the monitor listed.



  • Something is up with the Dock-Mac. Could be firmware. I have a Lenovo Thunderbolt 3 dock that refused to do 1440p/60hz in Windows, but would on my Mac only to drop out every few minutes. Firmware update solved both sets of issues.

    Had another USB C dock that used DisplayLink, which wouldn’t do above 30hz on my Mac until I downloaded the DisplayLink driver.

    What’s the dock you are using in the office?
