Explanation
Not all USB-C cables support video output (DisplayPort Alt Mode) or Thunderbolt, even though they carry power. A charge-only USB-C cable will work for charging tests but won’t pass the video signal to the projector. You need a USB-C cable rated for Thunderbolt or DisplayPort Alt Mode to transmit the display data directly.
