Quick Tips Before You Start

Before connecting your computer to an external display, here are a few things to keep in mind:

  • Identify Your Ports: Check what video ports are available on both your computer and the external display. Common ports include HDMI, DisplayPort, USB-C (with DisplayPort or Thunderbolt support), and VGA.
  • Get the Right Cable: Make sure you have a compatible cable or adapter. HDMI cables support both video and audio on a single cable, making them ideal for TVs.
  • Check USB-C Capabilities: Not all USB-C ports support video output. Your USB-C port must support DisplayPort Alternate Mode or Thunderbolt to transmit video signals. Check your computer's documentation if you're unsure.
  • Consider Wireless Options: If your TV or display supports Miracast, you can connect wirelessly without cables. This option is covered in the laptop connection guide.
