1235 My USB hub (or device) is not working properly on Sonnet Echo 11 Dock
You can connect a four-port USB hub (or device with an internal USB hub) to any of the Dock’s USB ports. You cannot connect a hub (or device with an internal USB hub) that has more than four USB ports. The USB specification does not permit another level of cascaded hubs. You may connect a hub with more than 4 ports to a Thunderbolt port.
1002 Two USB-C to 4K HDMI Adapters Are Not Working Properly Under macOS Ventura With M1 or M2 Macs
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.
1151 Dock- Why Isn't There 100 W of Power Delivery
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.
1154 My M3 Computer Can't Connect to Multiple Displays Connected to Thunderbolt Dock
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,
