The USB-C input is “plug and play” — you don’t need to do anything on the projector. As soon as you plug in the cable, the projector will switch to it.
Note that there are two USB-C ports: one only for charging, and one only for video. The correct one for video is shown below:
If it’s not working, try the following:
- Are you using the supplied USB-C cable, or another cable? If you’re using another cable (e.g. the charging cable of your notebook), please first try with the included cable.
- Are you plugging into the correct USB-C port on the PicoPix Max? There’s one only for charging, and one only for video. Please use the video port!
- Is an HDMI cable also plugged in? If yes, unplug all cables and then plug the USB-C cable back in. The projector automatically switches to the last-plugged input.
- Have you enabled USB-C video output on your laptop?
- If you have any other devices with USB-C video output, does plugging them into the PicoPix work fine?
You can also try upgrading the USB-C video chip firmware by following the instructions here.
If nothing works, it’s possible that your device does not support “DisplayPort Alternate Mode” for USB-C video output.
