3) Unzip the firmware update tool and launch the “CheckVersionUpdate” file.

4) If Microsoft Defender prevents the app from opening select "More info" and then select "Run Anyway".

5) If a prompt asks to run the program as an Administrator, click yes.

6) The program will automatically detect the chipset version of your USB-C to DP cable, and update the firmware if the chipset version is the correct version.
