Connect OnePlus 5T to TV: Wired and Wireless Ways

To connect your OnePlus 5T to a TV, you can use a USB-C to HDMI cable for a direct wired connection, or use wireless methods like Chromecast, Miracast, or DLNA. This guide explains each option in detail, including what you need, how to set it up, and common issues you might face.

Understanding Your OnePlus 5T’s Video Output

The OnePlus 5T, released in 2017, does not have a dedicated video output port like HDMI. However, it supports video output through its USB-C port using the DisplayPort Alternate Mode standard. This means you can connect the phone to a TV or monitor with a USB-C to HDMI cable or adapter, provided the cable/adapter supports DisplayPort Alt Mode. Not all USB-C cables do, so you need to check the specifications before buying.

For wireless connections, the 5T runs on OxygenOS (based on Android), which includes built-in support for Chromecast, Miracast, and DLNA. These allow you to mirror your screen or stream media to compatible TVs and streaming devices.

Wired Connection: USB-C to HDMI

The most reliable way to connect your OnePlus 5T to a TV is via a wired connection. Here’s what you need:

• A USB-C to HDMI cable or a USB-C to HDMI adapter (with an HDMI cable).
• A TV with an available HDMI port.

Steps to connect:

1. Plug the USB-C end into your OnePlus 5T.
2. Plug the HDMI end into your TV.
3. Change the TV’s input source to the correct HDMI port.
4. Your phone’s screen should appear on the TV. If not, check that the cable supports DisplayPort Alt Mode.

Note: The OnePlus 5T does not support Samsung DeX or a desktop mode; it simply mirrors your phone’s display. This is fine for watching videos, showing photos, or playing games.

Wireless Connection: Chromecast and Miracast

If you prefer a wireless setup, you have two main options: Chromecast and Miracast.

Chromecast

Chromecast is a device that plugs into your TV’s HDMI port. To cast from your OnePlus 5T:

1. Connect the Chromecast to your TV and power it on.
2. Make sure your phone and Chromecast are on the same Wi-Fi network.
3. Open the Google Home app on your phone, tap the device, and select “Cast screen” to mirror your entire screen.
4. Alternatively, in apps like YouTube or Netflix, tap the Cast icon and select your Chromecast.

Chromecast works well for streaming video and music, and screen mirroring is also supported. The quality depends on your Wi-Fi network.

Miracast

Miracast is a standard for wireless screen mirroring that doesn’t require a Wi-Fi network; it creates a direct connection between devices. Many smart TVs have Miracast built-in (often labeled as “Screen Mirroring” or “Smart View”). To use it:

1. On your TV, enable the screen mirroring feature (check your TV’s manual).
2. On your OnePlus 5T, go to Settings > Bluetooth & Device Connection > Screen Mirroring.
3. Your phone will scan for available devices; select your TV from the list.
4. Follow any on-screen prompts to connect.

Miracast is useful if you don’t have a Chromecast, but it can be less stable and have higher latency than wired connections.

Using DLNA for Media Streaming

DLNA (Digital Living Network Alliance) allows you to stream media files from your phone to a DLNA-compatible TV or media player without mirroring the entire screen. This is ideal for watching videos or viewing photos stored on your phone.

To use DLNA:

1. Ensure your TV supports DLNA (most smart TVs do).
2. Connect both devices to the same Wi-Fi network.
3. Use a DLNA-enabled app on your phone, such as BubbleUPnP or LocalCast.
4. Select the media file you want to play and choose your TV as the playback device.

DLNA is less common now, but it’s still a viable option for local media streaming.

Choosing the Right Method for Your Needs

Here’s a quick guide to help you decide:

• For gaming or low-latency needs: Use a wired USB-C to HDMI connection. It offers the best performance with no lag.
• For streaming from apps: Chromecast is the most convenient and reliable.
• For quick screen mirroring without extra hardware: Miracast is a good option if your TV supports it.
• For playing local media files: DLNA is efficient and doesn’t drain your battery as much as mirroring.

Consider the content you want to display and the equipment you already have.

Common Problems and Troubleshooting

If you encounter issues, here are some solutions:

• No signal on TV with wired connection: Make sure the cable supports DisplayPort Alt Mode. Try a different HDMI port on the TV. Restart your phone.
• Wireless mirroring is laggy or disconnects: Move closer to your Wi-Fi router, or ensure no other devices are hogging bandwidth. For Miracast, try moving closer to the TV.
• Chromecast not found: Ensure both devices are on the same Wi-Fi network and that Chromecast is powered on. Restart the Google Home app.
• Screen mirroring not supported by TV: Some older TVs don’t support Miracast. In that case, use a Chromecast or wired connection.
• Audio not playing through TV: Check the TV’s audio output settings. For wired connections, the audio should automatically route through HDMI.

Frequently Asked Questions

Does the OnePlus 5T support HDMI output?

Yes, it supports HDMI output via its USB-C port using DisplayPort Alternate Mode, but you need a cable or adapter that explicitly supports this standard. Standard USB-C cables won’t work.

Can I use a USB-C to VGA adapter?

Yes, if the adapter supports DisplayPort Alt Mode, you can connect to a VGA monitor, but you’ll need an active adapter that converts the signal. However, HDMI is more common for TVs.

Why doesn’t my phone show on the TV when I plug it in?

Likely because the cable or adapter doesn’t support video output. Check the product specifications for “DisplayPort Alt Mode” or “Video Output.” Also, make sure the TV is set to the correct HDMI input.

Can I connect to a TV that doesn’t have HDMI?

If your TV only has composite or component inputs, you can use an HDMI-to-composite converter, but the video quality will be lower and you’ll need additional equipment. Wireless options like Chromecast also require HDMI.

Does screen mirroring work with any TV?

No, screen mirroring via Miracast requires the TV to support Miracast. Many smart TVs do, but older models may not. Chromecast is a universal solution as it plugs into any TV with HDMI.

Can I use the phone while it’s connected to the TV?

Yes, the phone remains fully functional. You can use it as a remote, browse the web, or use other apps while the display is mirrored on the TV.
