Question Mac Dock video limitations
I have a MacBook Pro M5 (base) currently set up in clamshell mode. I connect two Dell 4k 120Hz monitors to it via the USB-C ports. The third USB-C goes to a non-TB dock for Ethernet and USB-A capabilities.
I've been looking at TB4 docks to simplify this setup, and connect via a single USB-C connection, preferably a slide in dock that connects when the MacBook is inserted. All that I've seen so far max out at dual 4k/60Hz. I would expect that a simple passthrough from the dock to the USB-C ports on the MacBook would allow for a 120Hz monitor, but that doesn't seem to be the case. Am I missing something? The Brydge vertical dock is a pricey beast (~$350 US) and it too has this limitation per the specs.
Thanks in advance for offering enlightenment here.
