Most smart TVs have USB ports, usually tucked away on the back panel next to HDMI ports, which means they often go unused. However, even a standard USB 2.0 port can unlock several practical uses for your TV — from displaying photos to powering external devices.
1. Photos and Videos Without Extra Copying
Your TV can act as a simple media player or slideshow. Just plug in a USB flash drive or external hard drive, and the system will usually offer to display the files immediately. The content plays directly from the drive — no need to copy it into the TV’s internal memory or cache, so files aren’t duplicated and the TV isn’t overloaded with extra data.
2. Use Your TV as a Second Monitor
If your computer screen feels cramped for documents, spreadsheets, or multiple windows, you can use your TV as an additional display. Connect it wirelessly with Bluetooth peripherals for extra workspace. While color accuracy or resolution may not match your primary monitor perfectly, it’s a convenient solution for expanding your desktop.
3. Stream Video on Older TVs Without a Nearby Outlet
Some streaming sticks plug into HDMI for video but get power via USB. For example, a Roku Streaming Stick can run off the TV’s USB port, eliminating the need for a wall outlet. Keep in mind that powering a streaming device from the TV may sometimes cause overheating, lag, or instability, though it often works fine.
4. Emergency Charging
You can charge a smartphone, game controller, or other device through the TV’s USB port — as long as you have the right cable. The drawback: most TV USB ports provide low power, so charging will be slow.
5. Firmware Updates via USB
For TVs without internet or smart features, USB is essential for updates. Manufacturers usually provide firmware files on their support pages. Download the update to a USB drive and install it on your TV. A restart may be required after the update.
As we approach 2026, the TV market is becoming increasingly complex, with new panel types and marketing names for familiar technologies. OLED remains the benchmark for image quality, though it also has specific limitations and characteristics.
