Many Nebula projector users may come across the image delay when using their projector.
This post will give solutions to this problem.
Solutions to the Problem
Update the firmware on your Nebula projector to the latest version by selecting Settings > Device Preferences > About > System Update.
Try to connect the Nebula to another HDMI output device (For example, a computer, a Fire TV Stick, a TV box) through HDMI only without connecting the Nebula to an external speaker via Bluetooth.
Change the projection mode on your Nebula projector to “game” mode, especially when you are doing game streaming.
a. Long-press the “settings” button on the remote after entering the HDMI input interface and the “Menu” option will come out.
b. Select “Picture Settings” and enter “Picture Mode”.
c. Choose the “game” option.
Reset your Nebula by going to Settings > Device preferences > Reset when nothing changes after trying all the above steps.
Causes of the Problem
The poor quality of the HDMI cable
A poor connection or the HDMI output device connected to your Nebula.
A Bluetooth speaker is connected to your Nebula simultaneously when it is connected to another output device through HDMI, which may cause the data transfer and decode process more complex and lead to an audio/image delay.
There is something wrong with the Nebula projector, such as firmware, system settings, or excessive amount of cache.
