Echo 5 Thunderbolt 4 Hub Support Library

Description: This is the English quick start guide for Sonnet’s Echo 5 Thunderbolt 4 Hub. This is revision F of this document.

Under macOS Ventura with M1 or M2 Macs, using two USB-C to 4K HDMI adapters will light one monitor at 60Hz and the second monitor at only 30Hz. If you have an M1 Max, Pro, or Ultra, we recommend the Sonnet Thunderbolt Dual HDMI Adapters, two of which will light four 4K monitors at 60Hz.

European Union regulations require that devices of this type shall not exceed 100W power delivery. For this reason, docks no longer provide, and computers no longer request, precisely 100W power delivery from a USB-C charging device. Tolerances in devices, components, voltage regulators, impedences, cable type and length, etc. could push 100W nominal power over 100W, which would exceed the hard limit of the specification. The mean power requested by computers that need ~100W, and the mean power provided by docks is nominally 96W with a range of 92-100W over a range of conditions. 100W is the maximum power provided under the most demanding conditions.

Hello,

I am sorry that your dock is not working as expected. Unfortunately, it is not possible to connect to multiple displays connected to the dock with an M3 Apple computer. Apple has a support article here on this topic . You will see in the last section of the article there is a section titled "If Your Display Won't Connect." Here it states that "If your display is connected to a hub or dock and you can use it only to mirror your built-in display, connect your display to a port directly on your Mac. "

Thanks,
