Compatibility Is Key It is easy to output audio and video from your USB-C devices via HDMI, as long as your source device has an HDMI chip and is therefore compatible. However, this is somewhat of a moot point since most of the latest smartphones and tablets support this straight out of the box.
Why is my USB C to HDMI adapter not working?
It might be the adapter went down, the HDMI to HDMI cable is not good quality, the HDMI cable length is over 15ft, or the display goes faulty on refreshing rate(even without any other connection), and there is also a slight chance that the host device (USB-C device) is not working well.
Is USB C to HDMI reliable?
That being said, the quality is almost negligible when it comes to USB C to HDMI adapters. The main reason behind that is the high data transmission rate supported by both USB Type C and HDMI. If you are going with a premium option, you can even get up to 4K resolution output at a 60 Hz refresh rate, if not higher.
Does USB C to HDMI need power?
The USB C to HDMI adapter features USB Power Delivery, so you can power your laptop while outputting video, using the same USB-C port. The adapter is also available in white (CDP2HDUCPW), so you can choose an adapter that matches the style of your laptop.
