Does the OnePlus OnePlus 8T support USB-C to HDMI?

No, it does not.

The OnePlus OnePlus 8T has no DisplayPort Alt Mode. A USB-C to HDMI cable will charge it, and the TV will stay on No Signal. This cannot be fixed with a different cable, adapter or app.

Confirmed by the manufacturer's documentation.

What works instead on the OnePlus OnePlus 8T

  • Browser Cast in the app. Your phone serves photos, videos and music to the TV's web browser over Wi-Fi. Nothing to install on the TV. Needs both devices on the same network.
  • Chromecast or Google TV. Cast from YouTube, Netflix and other apps directly, with DRM handled by the TV.
  • Smart TV casting. Samsung Smart View, LG Screen Share, or Miracast on most TVs mirror the phone wirelessly.
  • Return the cable. If you bought a USB-C to HDMI cable for this phone, it will never work with it. It is not defective.

Frequently asked questions

Why does my USB-C to HDMI cable not work on the OnePlus OnePlus 8T?
The OnePlus OnePlus 8T has no DisplayPort Alt Mode. The USB-C port carries power and data only, so the cable charges the phone and the TV sees nothing. The cable is not faulty.
Can an app or update add HDMI output to the OnePlus OnePlus 8T?
No. Video output is decided by the phone's chipset and port wiring. No software can enable it after the fact.
How can I connect the OnePlus OnePlus 8T to a TV then?
Wirelessly. Use the Browser Cast mode in the USB-C to HDMI app, which sends photos, videos and music to the TV's browser over Wi-Fi, or use a Chromecast, Miracast or a smart TV's built-in casting.
Will an MHL adapter work with the OnePlus OnePlus 8T?
No. MHL was a micro-USB era standard and is not supported on USB-C Android phones.
