Connecting a Google Pixel to an HDMI Display over USB-C

Before you start

Check whether the Pixel model supports video output over its USB-C port. Support can vary by generation and software version, so confirm this for the exact phone model before buying cables or adapters. The process is local: the phone drives the external display directly, and no separate service or app is required when the hardware and software support it.

You will need a USB-C to HDMI adapter or cable that passes video, a standard HDMI cable, and a display with an HDMI input. If you want to keep the phone charged during long use, choose an adapter with USB-C power delivery passthrough and connect a compatible USB-C charger. Keep the phone updated to the latest available software version from Google for the most predictable behavior.

Step-by-step instructions

Start with the external display turned off or set to a different input. Connect the HDMI cable to the display, then attach the USB-C end of the adapter to the Pixel. Connect the other HDMI end to the adapter and turn on or wake the display. If the adapter has power passthrough, connect the charger last.

Unlock the Pixel if necessary and watch for an on-screen prompt or automatic detection of the external display. On supported models, the picture may appear as a mirrored copy of the phone screen. Some versions offer a desktop-style interface or screen casting controls after the connection is recognized.

If nothing appears, remove and reseat the USB-C connection or disconnect and reconnect the adapter. Avoid using unpowered USB hubs in the path unless their video passthrough is explicitly supported. Also check that the display is set to the correct HDMI source.

Check the output

Confirm that the external display shows the expected phone content and that motion appears smooth. Play a short video or open the camera app to check that picture and sound behave as intended. Audio may stay on the phone or move to the display depending on the connection and settings, so test with a known source.

Be aware that mirroring may have a slight delay, and some protected or high-bandwidth content may not appear on the external screen. The available resolution and refresh rate depend on the adapter, the HDMI input, and the phone's output capabilities rather than on settings you can freely change.

Common problems and next steps

A blank screen is most often caused by an unsupported adapter path, a loose connection, an HDMI source mismatch, or missing video output support on that Pixel model. Test the same adapter and HDMI cable with another USB-C device that is known to support video output, and test the display with another HDMI source to narrow down the failure.

If the picture appears but there is no sound, check the phone's media volume and look for an audio output option while the display is connected. Some setups require selecting the HDMI device as the audio route manually. Keep the phone and relevant system components updated, and restart the phone only if a previously working adapter stops being detected after a software change.

For intermittent picture or dropouts, avoid extending the HDMI run with long or low-quality cables and remove unnecessary adapters from the chain. Support details for specific Pixel generations and software builds can change, so consult the official Google support information for the exact model when the basic checks do not resolve the issue.
