Connecting your phone to a TV is an incredibly useful way to enjoy videos, share photos, give presentations, or simply experience mobile content on a larger screen. If your phone comes with a USB-C port, using a USB-C to HDMI connection is one of the most stable and straightforward solutions available.
This guide explains how USB-C to HDMI works, which devices are compatible, and how to connect your phone to a TV step by step.
Can You Connect a Phone to a TV via USB-C?
The short answer is yes—but only if your device supports video output.
While many modern smartphones feature a USB-C port, not all USB-C ports support video transmission. To output video, the device must support DisplayPort Alt Mode (DP Alt Mode).
In general, many mid-range to flagship Android phones, tablets, and USB-C laptops support this feature. Before attempting to connect, it’s recommended to check your device’s official specifications to confirm USB-C video output support.
Why Use USB-C to HDMI?
Compared with wireless screen casting, USB-C to HDMI offers several clear advantages:
-
Stable connection with no reliance on Wi-Fi
-
Low latency, ideal for video playback and gaming
-
Plug-and-play operation with no apps or setup required
-
Support for higher resolutions and refresh rates
With a USB-C to HDMI cable that supports HDMI 2.0, you can enjoy smooth and clear 4K video output on a TV or external display.
What Do You Need?
Before getting started, make sure you have the following:
-
A smartphone that supports USB-C video output
-
A TV or monitor with an HDMI port
-
A USB-C to HDMI cable
For example, using a USB-C to HDMI 2.0 cable that supports 4K at 60Hz, such as a 6-foot USB-C to HDMI cable from LENTION, can help ensure a stable connection and clear visuals for everyday entertainment or work scenarios.
How to Connect Your Phone to a TV Using USB-C to HDMI
The process is simple and only takes a few steps:
Step 1: Connect the USB-C End
Plug the USB-C connector into your phone’s USB-C port.
Step 2: Connect the HDMI End
Insert the HDMI end of the cable into an available HDMI port on your TV or monitor.
Step 3: Select the Correct Input Source
Turn on your TV and switch the input source to the corresponding HDMI port.
In most cases, your phone’s screen will automatically mirror onto the TV. If it doesn’t, check your phone for any prompts related to external display or screen projection.
What Can You Do After Connecting?
Once connected, you can:
-
Watch videos stored on your phone or stream content on a larger screen
-
View photos and slideshows
-
Present documents or slides
-
Join video calls on a bigger display
-
Play mobile games with a larger visual experience
If the cable supports audio and video output, sound will also be transmitted directly to the TV without the need for extra speakers or audio cables.
Frequently Asked Questions
Why Is There No Display on the TV?
Common reasons include:
-
The phone’s USB-C port does not support video output
-
The TV is set to the wrong HDMI input
-
The cable does not support DisplayPort Alt Mode or high-resolution output
Check each of these factors to troubleshoot the issue.
Does USB-C to HDMI Affect Video Quality?
As long as you use a cable that supports HDMI 2.0 and your phone supports high-resolution output, you can achieve smooth, high-quality visuals—up to 4K resolution with stable performance.
Can I Charge My Phone While Using USB-C to HDMI?
Most standard USB-C to HDMI cables do not support charging. If you need to charge your phone while displaying content, consider using a USB-C hub that supports Power Delivery (PD).
Conclusion
Using a USB-C to HDMI cable is a simple, reliable, and efficient way to connect your phone to a TV. As long as your device supports USB-C video output and you use a quality cable, you can enjoy a smooth big-screen experience without the instability often associated with wireless casting.
For users who prioritize stable connections, low latency, and high-quality visuals, USB-C to HDMI remains one of the most practical screen-mirroring solutions available.
