First, use the autofocus feature to keep the image as sharp as possible without any manual adjustment.
Activate Autofocus by going to Settings > Projector Settings > Focus Settings > Auto Focus At Startup / Auto Focus After Movement.
Slightly move the device or press the focus button on the remote to trigger autofocus and auto keystone correction.
If that doesn't work, try the following:
Adjust the projection angle and direction, as well as the height of the projector.
Go to Settings > Projector Settings > Focus Settings and press Manual Focus Correction to adjust the focus.
Update your Nebula to the latest firmware version by going to Settings > Device Preferences > About > System Update > Check for update.
Restart your projector by going to Settings > Device Preferences > Restart.
If you still have a blurry image, contact us and include a short video showing what happens when you adjust the focus. When you email us, mention that you tried the recommended steps. This will help us find a solution for you much faster.
