How to Identify A Full-Function USB-C Port
- Look at your laptop's USB-C ports and find the Thunderbolt icon ⚡, D or DP symbol next to it (DP means DisplayPort) as shown above. If these icons are present, the ports are full-function USB-C ports.
- 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".
- If you are unsure of your laptop's compatibility, please let us know your laptop's brand and model so that we can help you determine if this product will work for you.
