Why isn't my keyboard/mouse working on the monitor’s built-in USB hub? How to connect my keyboard/mouse to the monitor?

05-21-2024

External devices, such as the keyboard and mouse, cannot work on the monitor if the USB downstream ports on the monitor are not activated. 

After downstream ports are activated, external devices that use these ports can start working on the monitor. 

Depending on your monitor connection ports, USB downstream ports can be activated in one of the following ways:

- If the video source is USB-C or Thunderbolt 3, the USB downstream ports will
  be activated automatically.

 

- If not, connect your computer to the USB upstream port on the monitor with
  the complimentary USB (USB-B to USB-A) cable. Then, connect USB devices
  via the other USB ports (downstream) on the monitor for data transmission.
