Go - USB-C Display Port Alt Mode

Looking Glass Go is designed to connect to your computer through a single USB-C cable using DisplayPort Alt Mode (DP Alt Mode). This article will guide you through understanding DP Alt Mode, checking if your computer supports it, and how to set up the connection.

Understanding DisplayPort Alt Mode

DisplayPort Alt Mode (DP Alt Mode) is a feature of the USB-C specification that allows a USB-C port to output DisplayPort video signals directly. This enables you to connect a display, like the Looking Glass Go, to a compatible USB-C port without needing a separate video cable.

Checking Your Computer's Compatibility

Windows Laptops

  • Look for the Thunderbolt (lightning bolt) or DisplayPort (DP) logo next to your laptop's USB-C ports. If present, the port supports DP Alt Mode.
  • If there are no logos, find your laptop's model number in Settings > System > About. Search for the model online and check the manufacturer's specifications to confirm if the USB-C ports support DP Alt Mode or DisplayPort output.

MacBooks

  • MacBooks don't have port capability logos. Find your MacBook's model identifier by clicking the Apple menu > About This Mac.
  • Check the specifications for your model on Apple's website. Look for "Native DisplayPort output over USB-C" under Display Support to confirm DP Alt Mode compatibility.

Desktop PCs

  • Check if your PC's motherboard has a USB-C port that supports DP Alt Mode. Refer to the motherboard manual or manufacturer's website for specifications.
  • If your graphics card has a USB-C port, check the card's specifications to see if it supports DP Alt Mode.

Using an Adapter for Computers without DP Alt Mode

If your computer doesn't have a USB-C port with DP Alt Mode, you can use an adapter cable to connect its HDMI or DisplayPort output to the Looking Glass Go's USB-C input. Currently, you can purchase a HDMI adapter directly from Looking Glass.


By following this guide, you should be able to determine if your computer can connect to the Looking Glass Go using DP Alt Mode and select the appropriate cable or adapter.
