This guide walks you through the process of connecting your smartphone to your television using a USB cable. It also covers how to add USB functionality if your TV doesn’t have a port and explains the benefits of using a wired connection.

How to Connect Your Phone to Your TV via USB

Connecting your phone to your TV using a USB cable is a straightforward process, similar to hooking up a streaming stick or gaming console. If you have your TV’s user manual, it’s a good idea to review it first—it often includes details about port locations and compatibility.

Follow these simple steps:

1. Locate the USB port on your TV. Most modern flat-screen TVs come equipped with at least one USB port, typically found on the side or back panel alongside other input ports. If your TV doesn’t have one, see the solutions below.
2. Connect your phone using the appropriate USB cable. Plug one end into your TV’s USB port and the other into your phone. If the connection is successful, your phone should begin charging immediately.
3. Switch the TV input to USB. Use the Source button on your remote control, the TV itself, or navigate through the on-screen menu to select the USB input.
4. View your phone’s screen on the TV. Once connected, your phone’s display should appear on the television. For best results, adjust your phone settings—rotate videos to landscape mode, disable auto-rotate and screen lock, and consider using a phone stand for optimal viewing.

Why Use a USB Connection From Phone to TV?

While wireless screen mirroring (or casting) is convenient, it often comes with drawbacks. Stability is a major concern: data must travel from the internet to your phone, then through your Wi-Fi network, and finally to your TV. Each step introduces potential for lag or disconnection—especially during high-demand activities like online gaming or group video calls.

Even direct wireless links between devices can falter. These connections rely on radio signals, which may be interrupted by interference from other electronics (like cordless phones or microwaves). Additionally, both your phone and TV run background processes that can consume resources, leading to slowdowns or dropped signals.

Battery life is another factor. Although you can charge your phone while casting, it’s easy to forget—especially during long sessions. A low battery may force your phone to throttle performance, weakening the connection.

These issues often result in buffering, stuttering, or frozen screens. A USB cable eliminates many of these problems by creating a direct data link between your phone and TV, bypassing Wi-Fi and routers entirely. Some TVs can even power your phone during use. This method treats your phone like a standalone device—similar to a Blu-ray player or set-top box—rather than relying on casting tech like Chromecast.

Troubleshooting: Phone Not Connecting to TV

If your phone isn’t showing up on the TV, two common issues could be at play—and both may be resolved with the right adapter.

Your TV Lacks a USB Port

If your TV doesn’t have a USB port, you can still connect using an adapter. Most TVs have HDMI ports, so a USB-C to HDMI adapter (or Micro USB to HDMI, depending on your phone) lets you plug your phone into the TV via HDMI. Keep in mind that this setup may not charge your phone, so keep an eye on battery levels.

These adapters are widely available on platforms like Amazon, especially for phones with USB-C ports.

TV Doesn’t Recognize Phone as a Source

Some TVs only read USB devices as storage (like flash drives), even if they support media playback. In this case, your TV might not recognize your phone as a video source. Using a compatible adapter—such as an MHL (Mobile High-Definition Link) adapter—can help the TV detect your phone properly and enable screen mirroring.

Once the connection is established and recognized, play a video file or stream content from an app, and it should display directly on your TV screen.

22. What if my TV doesn’t have HDMI?
    If your TV doesn’t support HDMI, check for an MHL (Mobile High-definition Link) port. You’ll likely need an MHL-certified cable and possibly an adapter to connect your phone and mirror the screen.
