If you cannot control an HDMI device using the HDMI
Link buttons, try the following solutions:
- Make sure
all necessary cables are securely connected and the power is on for
the projector and connected video sources.
- Make sure the cables meet the HDMI CEC
standard.
- Make sure the connected device meets the HDMI CEC
standard. See the documentation supplied with the device for more
information.
- Make sure the HDMI
Link setting is set to On.
- Check if the device is available in the Device Connections list in the Settings menu. If the device does not appear,
it does not meet the HDMI CEC standards. Connect a different
device.
- Make sure the connected devices are turned on and in
standby status. See the documentation supplied with the device for
more information.
- If you connected a new device or changed any
connections, make sure the CEC function is set for the connected
device. You may need to restart the device.
- Connect no more than three devices that support HDMI
Link at the same time.
- If you have connected a speaker or receiver, set the
output to PCM.
- If your projector shuts itself off, the connected
video source may be turning off the projector. Try turning off the
HDMI Link setting on the
projector and video source. See the documentation for your device
for information on how to disable the HDMI Link setting.
