Connecting your Android phone to a TV with a USB-C to HDMI adapter is a simple way to view your phone’s screen on a larger display. This setup is useful for watching videos, sharing photos, playing mobile games, giving presentations, or using supported phones in a desktop-style mode.
A wired USB-C to HDMI connection can also be more stable than wireless casting because it does not rely on Wi-Fi.
Before getting started, it is important to know that not every Android phone with a USB-C port can send video to a TV. The phone must support video output through USB-C, often called DisplayPort Alt Mode. Many flagship Android phones support this feature, while many budget and mid-range phones do not.
Before buying or using a USB-C to HDMI adapter, check your phone’s specifications or user manual to make sure it supports USB-C video output.
Common Android phones that may support USB-C to HDMI include:
Compatibility can vary by model, so always confirm support for your specific device.
Plug the HDMI end of your cable or adapter into an available HDMI port on your TV or monitor. Make a note of which HDMI port you used, such as HDMI 1, HDMI 2, or HDMI 3.
Plug the USB-C end of the cable or adapter into your Android phone. Make sure the connection is secure.
If you are using a separate USB-C to HDMI adapter, connect an HDMI cable from the adapter to your TV.
Turn on your TV and use the remote to select the HDMI input where your phone is connected. This is usually done by pressing the Input, Source, or HDMI button on the remote.
If your phone supports USB-C video output, your screen should appear on the TV automatically within a few seconds.

If your phone does not appear on the TV, try the following:
Wireless casting can be convenient, but a wired USB-C to HDMI connection often provides a more reliable experience. It can help reduce lag, avoid Wi-Fi connection issues, and provide better performance for gaming, presentations, and video playback.
No. Your Android phone must support video output through USB-C. If it does not, a standard USB-C to HDMI cable will not display your phone screen on the TV.
The most common reason is that the phone does not support USB-C video output. Other possible causes include using the wrong HDMI input, a loose connection, or an incompatible adapter.
Most basic USB-C to HDMI cables do not charge your phone while in use. Some adapters include an additional USB-C charging port so you can connect power while using HDMI.

Connecting an Android phone to a TV using USB-C to HDMI is a simple and reliable way to view your phone on a larger screen. Before you begin, make sure your phone supports USB-C video output. Once connected, you can enjoy videos, photos, games, presentations, and supported desktop-style features like Samsung DeX.
