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 standards.
- Make sure the connected device supports the CEC standards.
- If you connected a new device or changed any connections, 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.
