Within M1, Monterey or the MacBook Pro's at all, what is the recommended length of the cable to support Power Delivery (PD) and Video-Transmission? I mean, which standard should be at least supported by the cable (e.g. USB-C Hub function not working/supported anymore as worked with Big SurĪny hints? Does anybody else saw that issue within his/her devices after updating to Monterey?ĭoes anybody know, which cables are supported?.video link/connection randomly established through USB-C connection.no charging done via monitor USB-C connection.within less than one seconds, power supply icon changed back to the battery icon.battery icon changes to the power supply icon.you hear a sound as usual, when connecting a power device to the MacBook Pro.Plug in the USB-C cable from the monitor to the MBR.MacBook Pro (M1 2020) is started and running on battery mode (seen on the battery icon on the menu bar), no other devices connected to the MBP.

USB-C 3.1 shown on the sticker of the cable) USB-C cable is connected to the monitor and the other end of the cable is waiting to be connected to an other device. Mouse and Keyboard is connected to the monitor.Monitor is plugged in with the original powerful power supply.with Big Sur, short before updating to Monterey, everything was working as expected. No change beside the update from Big Sur to Monterey done and still losing feature of Power Delivery via USB-C and video-connection sometimes. Mouse and keyboard is transmitted through the USB-C connection and sometimes, also the video-connection from MBP to the monitor is established. My MBP is connected only with USB-C to my external monitor (HP S340c) and now, after updating to Monterey, no charging via that connection. Does anybody saw the issue about not working PD (Power Delivery) via USB-C cable when updating MacBook Pro M1 2020 to Monterey?
