picture quality is poor.
Depending on the signal strength and the location of the projector and Wireless unit, images from
the HDMI devices may not be projected properly. Change the location and orientation of the
projector and Wireless unit.
Make sure that there are no obstructions blocking the radio wave between the projector and
Wireless unit, and make sure that the projector and Wireless unit are not placed too far away
from each other.
When an interlaced video signal is input, the picture quality may be poor.
If a message “Input video from HDMI is interlaced. This may cause the video to display
incorrectly. Check the output settings of the device connected to the Wireless unit for a non-
interlaced option.” appears, set the output resolution of the HDMI output device to “Auto,”
“1080p,” or “720p.”
[58] Troubleshooting/frequently asked questions
Frequently asked questions
The projection screen dims automatically, or the
projection screen turns off.
When the projector is used in a hot environment, or the ventilation holes (intake/exhaust) are
blocked, the brightness is automatically reduced to cool down the inside of the projector. If the
temperature in the projector is not cooled down even when the brightness is reduced, the
projection automatically stops.
[59] Troubleshooting/frequently asked questions
Frequently asked questions
Poor picture quality.
The projector uses wireless LAN and Bluetooth communication, therefore the communication
range may become short depending on the environment such as an obstruction between the
projector and Wireless unit (or your smartphone), signal strength, and wall material. In such a
case, change the projector’s location, or bring your device and the projector nearer to each other.
If the projector is used near another device which uses wireless LAN or Bluetooth
communication, interference may occur causing low communication speed or connection failure.
In such a case, move the projector away from the other radio device. If the problem persists, turn
off the other radio device.
