How to Identify A Full-Function USB-C Port

1. Look at your laptop's USB-C ports and find the Thunderbolt icon ⚡, D, or DP symbol next to it (DP means DisplayPort). If these icons are present, the ports are full-function USB-C ports.
2. If you don't see these symbols, check your laptop's manual to see that your USB-C port has display support or if the manual mentions "DP Alt-Mode".
3. If you are unsure of your laptop's compatibility, please provide your laptop's brand and model so that we can help you determine if this product will work for you.
