How to Use USB Upstream and KVM on a KTC Monitor

USB upstream and KVM on a KTC monitor may depend on the upstream connection, the switching path between devices, and whether USB-C is carrying display and data together. Check the parts that match your setup. If these steps do not fit your screen, use the model links below for exact instructions.

What to check

Check the upstream connection

The simplest setup is one computer connected to the monitor's upstream path.

Check this:

  1. Connect the monitor video cable first.
  2. Connect the monitor's USB upstream path to the computer.
  3. Connect the keyboard, mouse, or other USB devices to the monitor.
  4. Check whether the connected USB devices begin working.

If the video works but the USB devices do not, the upstream connection is usually the missing step.

Check the KVM switching path

A KVM-capable monitor may switch USB control together with the active video source.

Check this:

  1. Connect each source device with its own video path.
  2. Connect the required USB upstream path for each device if the model uses more than one.
  3. Connect the keyboard and mouse to the monitor USB ports.
  4. Switch the active source and check whether USB control follows the selected device.

Some models tie KVM behavior directly to input switching, while others use a dedicated menu item.

Check the USB-C integrated path

Some models combine video, charging, and USB data over one USB-C connection.

Check this:

  1. Connect the supported USB-C port on the source device to the monitor.
  2. Select the correct input if needed.
  3. Wait for the display and USB devices to appear.
  4. Test keyboard and mouse control after the picture is stable.

A full one-cable setup works only when the device, cable, and monitor all support the same USB-C features.

If the steps above do not match your screen

Before going to the model list, try these quick checks:

  • confirm that the model actually supports USB upstream or KVM
  • check whether the USB devices are plugged into the correct monitor ports
  • compare the result with a direct USB connection to the computer
  • remove docks or adapters during the first test if USB behavior is unclear
