When you connect HDMI CEC-compatible devices to the
projector with HDMI cables, you can control them on the
same power on or power off status using the HDMI CEC
control feature in the projector's OSD. This lets one device or
multiple devices in a group power on or power off via HDMI
CEC in a typical configuration.
NOTE:
• In order for the CEC function to work properly,
make sure that the device is correctly
connected to the HDMI input of the projector
via an HDMI cable, and its CEC function is
turned on.
• If both HDMI 1 and HDMI 2 ports are
occupied, the CEC function will not be able to
detect the correct source.
• Depending on the connected device, the CEC
function may not work.
Select the test pattern from green grid, magenta grid, white
grid, white, test card or disable this function (off).
