What is the main difference between a standard USB-C port and one that supports HDMI?
The main difference between a standard USB-C port and one that supports HDMI is that the latter has an alternate mode, or “alt mode,” which allows it to carry non-USB signals, such as HDMI and DisplayPort. This is achieved through a special chip that enables the port to switch between USB and display modes. When in display mode, the port can transmit video signals to an external display.
However, not all USB-C ports with alt mode support HDMI. Some may only support DisplayPort or other display protocols. To ensure compatibility, it’s essential to check the specifications of your device and the accessories you plan to use. This will help you determine which devices can be connected and what types of cables or adapters are needed.
