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

10-20-2025

To utilize the USB-A (rectangular) ports on your monitor, a USB connection between your computer and the monitor is necessary. You can establish this connection in one of two ways:

 

  • USB-C Connection: If your computer supports USB-C, you can connect it to the monitor using a USB-C to USB-C cable. This option also supports video transmission.

 

  • USB-B Connection: Use the included USB-A to USB-B cable. Connect the USB-A end to your computer and the USB-B end to the monitor. This method is suitable if you are using an HDMI or DisplayPort cable for video transmission.

 

Once the USB connection is established, the monitor’s built-in USB hub will be activated, allowing you to connect and use USB devices, such as a keyboard or mouse, through the monitor’s USB-A ports.
