Please try the following steps to confirm and resolve the problem:
- Please make sure all cables are connected to the projector properly and stably.
- Check whether the projector input source mode has been selected as the corresponding format.
For example, the device and the projector are connected with an HDMI cable, the HDMl input channel must be selected for projection, and no signal will be displayed if other channels are selected.
- Replace the HDMI cable
