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.
- 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.
