Your smart TV has a USB port primarily for playing media (photos, music, videos) from a flash drive, but also to power devices like streaming sticks (Fire Stick, Roku), provide power for LED backlights for ambiance, or even connect accessories like USB keyboards for easier searching, offering versatile functionality beyond just watching built-in apps.
As long as your TV is equipped with a USB 2.0 connection or later, you should be able to use the port to power up your streaming gear. Alternatively, you can also use the port to charge a compatible phone, tablet, or other small mobile device.
The USB port on the TV may be used by the manufacturer or an engineer for software updates if necessary. This is not something you would need to worry about unless advised by an engineer or a support line to perform an update via this method. For older smart TVs, the USB port may be used to attach a Wi-Fi dongle.
To connect a USB device to your Smart TV and initialize it, perform the following steps:
It is commonly used for transferring data between computers and other peripherals such as printers, external hard drives, mice, keyboards, and more. USB offers fast speeds, reliable connections, and is incredibly versatile in its uses. USB ports can also be used to charge mobile devices such as phones and tablets.
Devices should be connected directly to the TV's USB port. When connecting an external hard drive, use the USB (HDD) port. We recommend that you use an external hard drive with its own power adapter. If there are multiple USB devices connected to the TV, the TV might not be able to recognize some or all the devices.
There's no practical difference between a flash drive and a USB stick; they are different names for the same thing, referring to a portable storage device using flash memory that connects via a USB port, also called a thumb drive or pen drive. "Flash drive" is the technical term from its technology, while "USB stick" describes its shape and interface, used interchangeably for these compact, key-chain-friendly devices for file transfer and storage.
While virtually all smart TVs have USB ports, they don't all offer the same features using those ports. So if you want to know the full capabilities of your TV's USB ports, you'll have to refer to its specific documentation.
USB ports are designed for data and power transfer, while HDMI ports are designed for video and audio transfer. USB ports can connect a wide range of devices and peripherals, while HDMI ports are mainly used for display and sound devices.
In the past, this often meant hooking up your TV to the speakers via things like auxiliary jacks, RCA cables, and even special HDMI ARC cables. For people who don't like the messy look of these wires, many modern smart TVs let you use Bluetooth connections with speakers instead.
TV Inputs/ Outputs – How They Work & What They Do
For Android devices, a USB cable can help you connect your phone or tablet to your TV, provided it has a USB port. If you're connecting to a smart TV, go to Source>USB to enable file transfers, instead of just charging the phone or tablet via the TV.
If you still have a charging cable, you can connect your phone to a USB port from an outlet, computer, or TV. This method can charge your phone, although it's typically slower.
Smart TV Connections
You can use either a wired Ethernet cable or built-in WiFi to connect and bring all the latest tech straight to your living room.
Connect one end of the coaxial cable to the output jack on your antenna. Attach the other end to the 'Antenna In' or 'Coaxial In' port on your smart TV. Access the settings menu on your smart TV and look for a section dedicated to channel tuning or antenna setup.
The most common use for USB ports on a smart TV is media playback. Usually the TV itself has a built-in media player that can play video, music, and images from a USB drive. You might also have the option to get third-party media player apps from your TV's app store, so that it can handle more media formats.
If your TV or display has a USB-C or Thunderbolt port, you can connect it using cable that came with your phone or tablet. Other USB-C and Thunderbolt cables will work with Netflix, but must support high-resolution video playback (USB version 3.1 or later).
A damaged HDMI cable or port can also prevent your phone from connecting to the TV. Loose connections, frayed cables, or unsupported resolutions can disrupt the signal. Solution: Try using a different HDMI cable or testing your current setup with another device.
USB was originally designed for computer peripherals like keyboards, mice, external disk drives, printers, scanners, cameras, and game controllers. However, mobile phones and tablets are among the most connected devices using USB alongside flash drives since their earliest iterations.
If your Roku device is getting an error message of "This USB device requires more power. Use a power adapter if available", it might be due to insufficient power supply. This occurs when the USB drive requires more power than the Roku device can provide.
iPhone models now include in the box a newer USB‑C to Lightning cable that supports fast charging and is compatible with USB‑C power adapters and computer ports that you might already have. You can use either a USB-A to Lightning cable or the newer USB-C to Lightning cable with your iPhone.
