Does the Samsung Galaxy A73 support USB-C to HDMI?
No, it does not.
The Samsung Galaxy A73 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.
Samsung's Galaxy A series uses a USB 2.0 port without DisplayPort Alt Mode. Wired HDMI output is not possible on this model. Use Smart View to a Samsung TV or the app's Browser Cast mode instead.

What works instead on the Samsung Galaxy A73
- 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 Samsung Galaxy A73?
- The Samsung Galaxy A73 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 Samsung Galaxy A73?
- 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 Samsung Galaxy A73 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 Samsung Galaxy A73?
- No. MHL was a micro-USB era standard and is not supported on USB-C Android phones.
