Operating In A High Altitude Environment; Using The Cec Function; Using The 3D Functions - ViewSonic PJD7828HDL User Manual

In the unlikely event that the capturing action fails, change your target picture. When the
resolution of the input signal is higher than the projector's native display resolution (See
"Projector specifications" on page 57
happens, please set the resolution of the input signal under native resolution and try again.

Operating in a high altitude environment

We recommend you use the High Altitude Mode when your environment is between 1500
m–3000 m above sea level, and temperature is between 5°C–25°C.
CAUTION
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature
is between 5°C and 35°C. The projector will be over cooled, if you turn the mode on under
such a condition.
To activate the High Altitude Mode:
1. Open the OSD menu and go to the SYSTEM
SETTING: ADVANCED > High Altitude
Mode menu.
2. Press /
message is displayed.
3. Highlight Yes and press Enter.
Operation under "High Altitude Mode" may cause a
higher decibel operating noise level because of increased fan speed necessary to improve
overall system cooling and performance.
If you use this projector under other extreme conditions excluding the above, it may display
auto shut-down symptoms, which is designed to protect your projector from over-heating.
In cases like this, you should switch to High Altitude Mode to solve these symptoms.
However, this is not to state that this projector can operate under any and all harsh or
extreme conditions.

Using the CEC function

This projector supports CEC (Consumer Electronics Control) function for synchronized
power on/off operation via HDMI connection. That is, if a device that also supports CEC
function is connected to the HDMI input of the projector, when the projector's power is
turned off, the power of the connected device will also be turned off automatically. When
the power of the connected device is turned on, the projector's power will be turned on
automatically.
To turn on the CEC function:
1. Open the OSD menu and go to the SOURCE > Auto Power On > CEC menu.
2. Press /
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.
Depending on the connected device, the CEC function may not work.

Using the 3D functions

This projector features 3D function which enables you to enjoy 3D movies, videos, and
sporting events in a more realistic way by presenting the depth of the images. You need to
wear a pair of 3D glasses to view 3D images.
