Only if the USB-C port supports video output—typically DisplayPort Alt Mode, Thunderbolt or an explicitly documented display feature. Connector shape alone does not prove video support; verify the exact device specification and the display’s required resolution and refresh rate.
What this covers
- Phones, tablets and computers with documented video output over USB-C
What it does not cover
- ×Charge/data-only USB-C ports or adapters above the device’s supported display limits

ReversibleLook for DisplayPort Alt Mode, Thunderbolt, USB4 display support or an explicit external-display statement.
Match resolution and refresh rate
ReversibleConfirm the device, adapter, HDMI cable and display all support the intended format.
Connect directly for the first test
ReversibleAvoid a dock, switch or receiver until a direct device-to-display path works.
Power the adapter when required
ReversibleIf the adapter includes USB-C power input, connect a compatible charger so the device and adapter have enough power.
Look for the DP logo at the port
ReversibleIf your laptop's port has it, video will work with a compliant adapter. If not, try another port or a different route.
Use an adapter that states DisplayPort Alt Mode or Thunderbolt support
ReversibleAn adapter that only charges or carries data will give no picture on a port that supports video.
Dell's guide
What a USB-C to HDMI setup depends on
The adapter carries the picture only if the USB-C port sends video in the first place.
- The port
- Look for the DisplayPort (DP) logo near the USB-C connector. Dell says the standard delivers full DisplayPort audio and video up to 8K at 60 Hz, with USB data and up to 100 W of power on one cable.
- The adapter
- Adapters and adapter cables connect DisplayPort over USB-C to DisplayPort, HDMI, DVI and VGA inputs. A USB-C or Thunderbolt adapter must comply with DisplayPort Alt Mode, Thunderbolt 3 or Thunderbolt 4.
- If it fails
- On an unsupported port no video is sent and there is no picture, and Dell says this does not harm the device.
Stop boundary
When this stops being a self-service repair
- !Unplug the adapter and stop if it becomes very hot or the picture flickers repeatedly, and try a different certified adapter.

Exact questions
Common questions about “Will a USB-C to HDMI adapter work with this phone or laptop?”
Is there a risk in trying an unsupported port?+
Dell says none: no video is sent, there is no picture, and the device is not harmed.
Can one cable charge the laptop and drive the monitor?+
Dell says DisplayPort over USB-C can carry video, USB data and up to 100 W of power over a single cable.
How can I tell my port carries video?+
Look for the DisplayPort (DP) logo near the USB-C connector, which Dell says marks connectors that support DisplayPort over USB-C.
What resolutions are possible?+
Dell says the standard supports full DisplayPort audio and video up to 8K at 60 Hz, but the real limit is set by the port, the adapter and the monitor.
Which adapters are compatible?+
Dell says a USB-C or Thunderbolt adapter must comply with DisplayPort Alt Mode, Thunderbolt 3 or Thunderbolt 4.
Do some phones not support it?+
Yes, many do not.
Is there a wireless option?+
Yes, casting can work.
Why is my HDMI display blank or at the wrong resolution?+
A blank screen usually means the port does not output video, the adapter is faulty or the cable is charge-only. A wrong resolution can come from an adapter limited to a lower resolution or refresh rate. Try another adapter or cable, and set the resolution in display settings.
