Thank you for your support of our products. 

To ensure the best projection quality, we have added a feature that senses changes in ambient light in real-time. This means that when there are significant changes in the brightness of the video itself, the projector may automatically adjust its brightness.

To prevent the video’s brightness changes from affecting the projector’s ambient light sensing function, you can manually disable the Ambient Light Adaptation.

Go to Settings > Display & Sound > Picture > Ambient Light Adaptation

We apologize for any inconvenience this may cause.

If the above solutions cannot solve your issue, please contact Nebula Customer Support at support@seenebula.com for further assistance.
