If necessary, change their positions to improve communication. Also make sure that they are not too far apart; move them closer together and try to connect again.

• If the wireless connection is slow or your projected image contains noise, check for interference from other equipment, such as a Bluetooth device or microwave. Move the interfering device farther away or expand your wireless bandwidth.

• If the connection speed declines, reduce the number of connected devices.

Solutions When the Image or Sound Contains Static During Screen Mirroring

If the projected image or sound contains static during Screen Mirroring, try the following solutions:

Solutions to Problems Using Content Playback

If you cannot play back a playlist correctly, try the following solutions:

• Check the following on all projectors:

• All projectors are the same model. If any of the projectors are a different model or have a different resolution, synchronized playback may not be performed properly.

• Make sure the name, date, and time settings are correct.

• Make sure all projectors are connected to the same network.

• Make sure the Content Playback setting is turned on in the Operation menu.

• Make sure your USB device contains a playlist.

• Make sure your USB device is connected directly to the projector and not through a USB hub or card reader.

• If the USB device is partitioned, you may not be able to play back playlists. Delete all of the partitions before saving the playlists on your USB device.

• Do not share a playlist between projectors that are different in resolution. Color and shape effects added by using the Overlay Effect setting may not be reproduced correctly.
