USB-C 3.2 Gen 2 10Gbps 100W Cable
The U2723QE requires a high-bandwidth 10Gbps connection to support simultaneous 4K video, USB data, and Ethernet. Standard charging cables lack the high-speed differential pairs required for the hub to function, leading to 'Not Working' symptoms where video might display but peripherals fail. This cable ensures proper E-marker identification and signal integrity for the USB-C Alt Mode handshake.

Main Interface Logic Board
The internal USB hub, Ethernet controller (Realtek), and DDC (Display Data Channel) communication are managed by the main logic board. A hardware failure in the Cypress or Realtek controller chips on this board results in the OS failing to recognize the downstream USB tree. Replacing this board restores the electromechanical path for data transmission and power negotiation.

Internal Power Supply Board
The USB hub requires stable 5V/12V rails provided by the internal power supply to drive connected peripherals and the Ethernet chip. If the power supply board develops capacitor leakage or MOSFET failure, it may provide enough power for the LCD panel but insufficient current for the high-draw USB-C PD hub functions, causing them to drop out.
