If you feel like you need a bigger screen to watch movies or set up dual monitors for your work, what you need to do is source out your content to another bigger, better screen. 

You have USB-C connectors in your mobiles, tablets, and some laptops. For monitors and TV screens, you have HDMI connectors. To allow streaming directly from your mobile to your TV screen, you would require a USB-C to HDMI cable. 

You don’t even require an HDMI adapter in between, how cool is that! 

But what are the exact requirements and exactly how to use USB-C to HDMI, let’s find out.


 USB has different standards namely 3.0, 2.0, etc.   These differ in terms of data transfer speed.

Before we begin, an important thing to understand is that not all devices with a USB type C port can stream data through a USB-C to HDMI cable. USB has different standards namely 3.0, 2.0, etc. 

These differ in terms of data transfer speed. 

A USB type C port may support any of these standards but to provide output for an HDMI port,your device needs to have a USB-C 3.1 port or a thunderbolt 3 port, which supports DP Alt mode

USB-C 3.1 would either mean USB-3.1 Gen 1 (also called USB-C 3.0) or the USB-C 3.1 Gen 2.

If you are thinking about what a thunderbolt port is; by looks, a thunderbolt port is the same as that of a USB-C port but the difference lies in the speed. Thunderbolt 3 gives a maximum data transfer speed of 40 Gbps which is four times that of USB-C 3.1.

This was a video and data transfer protocol developed by Intel, but plug-in perspective remains the same as a USB-C. Thunderbolt port would have a lightning bolt-shaped label beside it.
