Solutions When the Image Contains Static During Network Projection
If the projected image contains static during network projection, try the following solutions:
• Check for any obstacles between the access point, the computer, the mobile device, and the projector.
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.
