Why Don’t Monitor USB Ports Work with HDMI Alone?

Many people get confused when they connect their monitor with HDMI and discover the USB ports don’t work. This happens because HDMI cables only carry video and audio signals. They don’t transmit USB data.

A computer monitor with usb connection needs two separate connections:

1. HDMI (or DisplayPort) for the display signal

What is a USB Upstream Port on a Monitor?

The usb upstream port on monitor is the key to making your monitor’s USB ports work. It’s different from the regular USB ports you use for devices.

Here’s the difference:

• Upstream port: Connects the monitor TO your computer (usually USB-B, square shape)
• Downstream ports: Connect devices TO the monitor (usually USB-A, rectangular shape)

The upstream port acts like the entrance to a highway. It creates the connection between your computer and the monitor’s built-in USB hub. Without this connection, the downstream ports (the ones you actually use) have no path to communicate with your computer.

Most monitors place the upstream port on the back near the other connections. Look for a port that’s a different shape from the regular USB ports. It’s often blue if it’s USB 3.0, or black/white if it’s USB 2.0.

How to Connect Your Monitor Using USB Port?
