Yes, many tablets can output video through USB-C to HDMI, but only if the USB-C port supports DisplayPort Alt Mode or Thunderbolt. Not every USB-C port carries a video signal — some are charge and data only.
- Tablet’s USB-C port supports DisplayPort Alt Mode or Thunderbolt 3/4
- You use a quality USB-C to HDMI adapter or cable rated for video
- Your TV or monitor has a working HDMI input
- USB-C port is limited to charging or data only (e.g. Samsung Tab A 10.1)
- Cable or adapter is power-only and carries no video signal
- Tablet firmware or model does not support video output
What Makes a USB-C Port Video-Capable?
USB-C is a connector shape, not a feature set. The port has to carry DisplayPort Alt Mode — a protocol that routes video data through the USB-C pins to an HDMI adapter. Without it, plugging in any adapter produces nothing on screen. Thunderbolt 3 and 4 ports also support video output and are fully compatible.
To check your tablet, look in the spec sheet under “USB-C” or “video output.” If it lists DeX, MHL, or DisplayPort, video output is supported. You can also learn how to check whether your USB-C port supports video before buying any adapter.
Which Tablets Support USB-C to HDMI?
| Setup | Works? | Need | Note |
|---|---|---|---|
| Samsung Galaxy Tab S8 / S7 | Yes | USB-C to HDMI adapter | Supports DeX and DisplayPort Alt Mode |
| Samsung Galaxy Tab S6 / S5e / S4 | Yes | USB-C to HDMI adapter | DeX supported on S6 |
| Samsung Galaxy Z Fold series | Yes | USB-C to HDMI cable | Full desktop DeX available |
| Samsung Galaxy Tab A 10.1 | No | — | USB-C is charge/data only |
| iPad Pro (USB-C models) | Yes | USB-C to HDMI adapter | Supports video out natively |
Samsung’s support page for the USB-C to HDMI adapter lists compatible Galaxy devices and setup steps if you want to confirm your model officially.
Choosing the Right Adapter or Cable
Not all USB-C to HDMI cables carry video. Cheap cables labelled for charging will not work. Look for adapters that explicitly state DisplayPort Alt Mode support. For 4K output, you may need an active adapter. A passive adapter handles most 1080p and standard 4K 30Hz use cases fine.
- 1080p output — passive USB-C to HDMI adapter works
- 4K 60Hz output — use an active adapter rated for 4K
- Multi-port hub with HDMI — check hub specs, not just the USB-C port
If you have already tried an adapter and got no signal, see why USB-C to HDMI is not working for troubleshooting steps. Common causes include wrong cable type, a locked display output setting, or an incompatible hub.
Quick Check Before You Buy
- Search your tablet model + “DisplayPort Alt Mode” or “video output”
- Check the spec sheet for DeX, MHL, or DP support
- Buy an adapter that lists DisplayPort Alt Mode compatibility
- Test on a known-good HDMI display first
Bottom line: A tablet can output video through USB-C to HDMI only when its USB-C port supports DisplayPort Alt Mode or Thunderbolt. Premium tablets like the Samsung Galaxy Tab S series and iPad Pro work well with a quality adapter. Budget tablets often have charge-only USB-C ports and will not output any video signal regardless of the cable used.
