Ground pins (GND) are symmetrical and duplicated on both sides of the connector.Adapter has been fully tested for functionality on the 2018+ iPad Pro (mirroring only)/MacBook Air/iMac and iMac Pro/MacBook and MacBook Pro/Google Pixelbook/Dell XPS 13 & XPS 15/Lenovo Thinkpad/HP Spectre x360/Samsung DeX capable devices/Surface Laptop 3 and Surface Go/and many other systems which support USB-C DP Alt Mode.It is easy to carry and use, convenient for storage in your laptop bag when traveling. Video Signal: USB-C DP/HDMI Alternate Mode Displaylink Simple Plug-In & Display For USB-C DP Laptops May Need Additional Drivers For USB-A & USB-C Without DP Compatible With Mac, Windows, Chrome, & Linux Kickstand (NOT Included) Required For Use With Microsoft Surface Pro One of my adapters ( Choetech) says it uses DisplayPort 1.2 so I'd like to confirm this. I know that Macs support both HDMI and DisplayPort over USB-C Alternate Modes, and I'd like to know which. I have a 13' MacBook Pro 2016 (non-touchbar) which I've connected to a couple of HDMI displays.The SBU1 and SBU2 pins can be used both for communication between two connected devices, and for transmitting analog signals from the left and right channels. Four pairs of pins of high-speed data exchange (blue in the picture) are used simultaneously. Contacts in the center (D+ and D-) — data of the USB 2.0 interface and earlier versions are also duplicated, but crosswise. Power supply (+V) is symmetrical and duplicated on both sides of the connector. Please note, your USB C devices need support DisplayPort Alternate Mode (Video output) or Thunderbolt 3.
![]() Usb-C Alternate Mode Pro Mac And IMacIt is a logical continuation of the Lightning-cable, but not only for Apple devices anymore.Please note: it is necessary to distinguish between the concept of “ port” and “ connector”.The Type-C connector (jack) can be soldered to an old phone (instead of micro-USB), but the port will remain old USB 2.0. The speed here is with a margin, so there is no need for HDMI.Finally, USB-C is convenient because it is two-sided. In the alternative mode, Thunderbolt 3 can transfer data at speeds up to 40Gb/s (of course, with certain “ifs”, but more on that below).Thirdly, it is able to transmit video with resolution up to 5K. It is a spec for the use of original audio accessories.The new USB-C specification has opened up a number of new features for users.Firstly, USB-C has a new USB PD (Power Delivery) standard, according to which this port and the corresponding cables must ensure the transmission of voltage up to 100 W in both directions.Secondly, it has impressive data transfer rates. But it must be borne in mind that there are two various specifications, as well as many other configurations. When you to connect a high-speed device that maintains a USB 3 with that kind of cable, the message “This device can work faster” will appear on your computer and the data exchange speed will be much lower than when connected with a USB-3 cable.The second catch is related to fast charging protocols.The USB-C standard provides the ability to transfer energy with the capacity of up to 100 W (20 volts and 5 amps), which allows you to use this connector even when working with powerful laptops. USB-C IssuesIn such an abundance of contacts, transmitted protocols and signals, is where the first issue arises— they are not all used, which means that they are not necessary in each cable.Almost all USB charging cables can work only in USB 2.0 mode (they only have wires to data lines D+, D- and power). Smartphone models are sold with a new connector, but with an old port. The only pros are the symmetry and reliability of the connector.Thus, the presence of Type-C doesn’t mean anything. Mac equivalent for task managerHowever, in the 12-inch MacBooks everything remained unchanged. The 13-inch MacBook Pro models, until the recent update, had only two of the four ports (the ones on the left) with Thunderbolt 3 support.Since 2018, all the models with Touch Bar, all four ports support data transfer at full speed. USB-C 3.1 Gen 2 (up to 10Gb/s) + Thunderbolt (up to 40Gb/s) — for MacBook Pro 2016-2018 (dual port)That is, if you have a 12-inch MacBook, then you can forget about Thunderbolt 3, and would be foolish to overpay for supporting this specification when choosing a cable.MacBook 12″ supports video transfer via HDMI, VGA and DisplayPort (with the appropriate adapters), but to combine it with Thunderbolt devices will not work.There are many more interesting things happening with the MacBook Pro 2016 and newer versions. USB-C 3.1 Gen 1 (up to 5Gb/s) — for lineup of MacBook 12”
