Do Samsung Galaxy Tab A series phones support USB-C to HDMI?
No. Galaxy Tab A tablets do not support DeX or wired HDMI output. Only the Galaxy Tab S line does.
Samsung's Tab A models use a USB 2.0 port without DisplayPort Alt Mode. If you need a Samsung tablet on a TV over a cable, you need a Tab S4 or newer Tab S.

What to do with a Galaxy Tab A series phone
- Browser Cast in the app. The phone serves photos, videos and music to the TV's web browser over Wi-Fi. Nothing to install on the TV.
- Chromecast or a smart TV. Cast from YouTube and streaming apps directly, with DRM handled by the TV.
- Return the cable. A USB-C to HDMI cable bought for this phone will never work with it and is not defective.
The full explanation is in how DisplayPort Alt Mode works.
Frequently asked questions
- Which Samsung Galaxy Tab A series models support USB-C to HDMI?
- None. No model in the Galaxy Tab A series has DisplayPort Alt Mode.
- Why does my Galaxy Tab A series phone charge but not show on the TV?
- Charging uses the power pins of the USB-C port. Video needs DisplayPort Alt Mode on the high-speed pins, which these models do not have. The cable is working; the phone cannot send video.
- Can an app enable HDMI output on a Galaxy Tab A series phone?
- No. Wired video output is decided by the phone's chipset and port wiring. The alternative is wireless: the Browser Cast mode in the USB-C to HDMI app, a Chromecast, or the TV's built-in casting.
- What cable works with the Galaxy Tab A series models that do support it?
- There is nothing to buy. Return the cable if you bought one for this phone.
