How do you get an HDMI signal?

To get an HDMI signal, you need to connect an HDMI cable from an HDMI output source, such as a computer, gaming console, or Blu-ray player, to an HDMI input on a display device, like a TV or monitor. Ensure both devices are powered on, and select the correct HDMI input source on the display. The HDMI cable transmits both audio and video signals, allowing you to enjoy high-quality multimedia output. If there is no signal, check the cable connections, settings, and ensure the devices are compatible.
