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.
For sure, I edited but that can take a minute, whats the dock you are using? I’ve been through a bunch of this stuff. If it’s a DisplayLink dock, you will get no love on MacOS without the driver, no mater what cables you use. If it’s one of the many USB based docks common to office fit outs, that might be your trouble.
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.
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.
My work issued Lenovo laptop only does 1440p/30 4k/30 with it’s built in HDMI and, for reasons that make sense only to Lenovo, also is 30hz capped when connected to their USB-C and Thunderbolt dock for who knows why. Drives me crazy.

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).

yes and the other ones are not displaylink
its connected in hdmi port 1.
yes, but it should be able to do 1080p 60.
as you say, they should do at least 1080p 60, they dont. because its not the cable or the dock.
That is indeed MildlyInfuriating - sucks dude!

you would think humanity has solved the Hdmi issue at this point…
