How to Connect HDMI to a KTC Monitor

Using HDMI on a KTC display may depend on the cable connection, the selected HDMI input, and the signal path. Check the sections 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 HDMI cable connection

A single direct HDMI cable is the easiest way to confirm the basic connection.

Check this:

  1. Connect the HDMI cable firmly to both the source device and the monitor.
  2. Turn on the display and the source device.
  3. Wait a few seconds for the picture to appear.
  4. Check the screen again after the device finishes waking up.

If the connector feels loose, reconnect it before changing other settings.

Check the selected HDMI input

Many monitors have more than one HDMI port, so the selected input must match the cable in use.

Check this:

  1. Open the monitor input menu.
  2. Choose HDMI, HDMI 1, or HDMI 2, depending on the port you used.
  3. Confirm the selection.
  4. Wait for the signal to appear.

Selecting the wrong HDMI port is a very common reason for a black screen.

Check the simplified signal path

If the setup includes extra devices, test the monitor with one direct HDMI cable first.

Check this:

  1. Disconnect adapters, switches, docks, or extension cables.
  2. Leave only one HDMI cable connected.
  3. Reconnect both ends of the cable.
  4. Test again before restoring the full setup.

This makes it easier to tell whether the issue is the cable path or the monitor settings.

If the steps above do not match your screen

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

  • confirm that the source device is sending video on the HDMI port in use
  • check whether the monitor has more than one HDMI input
  • try another HDMI cable if the picture flickers or never appears
  • restart the source device after reconnecting the cable
