The Overrated USB Port on Your Smart TV
Your TV's USB port is a nice feature, but it's not a major selling point. Most people purchase a TV for watching content, but it's capable of more.
Modern TVs come with various ports, including HDMI, USB, and Ethernet. The usefulness of these ports depends on the situation. For example, the Ethernet port may not be useful if the TV is far from the modem.
The USB port can be useful, but its functionality is limited. For instance, it can be used to power a Roku Streaming Stick, eliminating the need for an external power source.
Most TVs today have an assortment of HDMI, USB, and Ethernet ports, and how much those mean to you varies by situation.
Author's summary: The TV's USB port is not that important.
