USB-C to HDMI Cables: How To Use One Properly?


If you’re looking to watch videos from your phone on a larger screen or to set up duplicate monitors at your workstation, you’ll need USB-C to HDMI cables. Why? Your hand-held electronic devices, such as phones and tablets, probably have a USB- C connector, while bigger screens, such as TVs, are equipped with HDMI connectors. When you use the cable, the best thing is that you don’t need an adapter.

Connect the USB –C plug to your USB- C device.

Take the cable and insert it into the USB type-C on the bottom of the phone, tablet, or laptop.

USB ports come with different standards. Not every USB Type-C port can transmit data via USB-C to HDMI cable. Some USB-C ports don’t provide output for HDMI. Only the USB-C port supplying DP alt Mode allows video signal transmission. 

So, ensure your host device (the phone, tablet, or laptop) provides video. Therefore, it’s best to have a high-speed type with a 3.1 port. You can also use a thunderbolt, a modern high-speed port that offers max data transfer of up to 40 Gbps, which is much quicker than the USB-C 3.1.
