HDMI over USB-Type C cable | USB-C to HDMI Converter

This page covers HDMI over USB-Type C cable i.e. it provides USB-C cable which output HDMI format. Using this interface smart devices viz. tablet, smartphone, laptop can be interfaced with displays of various types.

HDMI | High Definition Multimedia Interface

The figure-1 depicts application of HDMI to USB converter. Following are the features of HDMI connector interface type.
• Supports compressed or uncompressed all digital audio as well as uncompressed video interface.
• Supports audio formats viz. DTS, Dolby etc.
• Supports video formats 720p, 1080i, 1080p, 480p etc.
• Supports NTPC, PAL standards
• Allows 8 channels uncompressed audio of different sample sizes 16 bit/ 20 bit/ 24bit with various sampling rates from 32 KHz to 192 KHz.


As shown in fig-1 it connects HDMI supported source devices such as PC monitor, projector, TV monitor and other digital audio devices with USB type-c compliant devices such as laptops, smartphones, desktops, tablets etc.
