Hiding the image
In order to draw the audiences full attention to the presenter, you can press BLANK to hide 
the screen image. Press any key on the projector or remote control to restore the image. The 
word BLANK appears at the lower right corner of the screen while the image is hidden.
You can set the blank time in the 
SYSTEM SETTING: BASIC > Blank Timer menu to 
let the projector return the image automatically after a period of time when there is no action 
taken on the blank screen. 
Once Blank is pressed, the projector enters Eco mode automatically.
CAUTION
Do not block the projection lens from projecting as this could cause the blocking object to 
become heated and deformed or even cause a fire.
Locking control keys
With the control keys on the projector locked, you can prevent your projector settings from 
being changed accidentally (by children, for example). When the Panel Key Lock is on, no 
control keys on the projector will operate except Power.
1. Press  (Panel Key Lock), or go to the 
SYSTEM SETTING: ADVANCED > 
Advanced > Panel Key Lock menu
2. Press / to select On.
3. A confirmation message is displayed. Select Yes to confirm.
To release panel key lock, press and hold   on the projector for 3 seconds.
You can also use the remote control to enter the 
SYSTEM SETTING: ADVANCED > 
Advanced > Panel Key Lock
 menu and press / to select Off.
Keys on the remote control are still functional when panel key lock is enabled.
If you press  Power to turn off the projector without disabling panel key lock, the projector 
will still be in locked status the next time it is turned on.
Creating your own startup screen
In addition to selecting the projector preset startup screen from among Black, Blue, or 
ViewSonic screen, you can make your own startup screen that is a picture projected from 
your computer or video source.
To create your own startup screen: 
1. Project the picture you want to use as your startup screen from either a computer or 
video source.
2. Open the OSD menu and go to the SYSTEM SETTING: BASIC > Screen Capture 
menu.
3. Press Enter.
4. A confirmation message displays. Press Enter again.
5. The message Screen Capturing... displays while the projector is processing the 
picture. Please wait.
6. If the action is successful, you see the message Captured Succeeded on the screen.  
The captured picture is saved as Screen Capture and have been set as your current 
startup screen. 
						

							38
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 for details.), the capture action may fail. When it 
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 / to select On. A confirmation 
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 / to select Enable.
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.
We recommend you use the High Altitude 
mode by selecting it whenever your 
environment is higher than 1500 m.
YesNo
Notice
Do you want to turn High Altitude 
Mode ON? 
						

							39
If the 3D signal is input from an HDMI 1.4a compatible device, the projector detects the 
signal for 3D Sync information and once detected, it projects images in 3D format 
automatically. In other cases, you may need to manually select a 3D Sync format for the 
projector to project 3D images correctly.
To select a 3D Sync format:
1. Press 3D on the remote control to access the 3D Settings menu or go to the 
SOURCE > 3D Settings menu.
2. Press Enter. The 3D Settings page is displayed.
3. Highlight 3D Sync and press Enter.
4. Press 
 to select a 3D Sync setting and then press Enter to confirm.
When the 3D Sync function is on:
• The brightness level of the projected image will decrease.
• The Color Mode cannot be adjusted.
• The Zoom function can only magnify the pictures to limited sizes.
If you discover the inversion of the 3D image depth, set the 3D Sync Invert function to “Invert” 
to correct the problem.
Using the projector in standby mode
Some of the projector functions are available in standby mode (plugged in but not turned 
on). To use these functions, be sure you have turned on the corresponding menus under 
SOURCE > Standby Settings, and the cable connections are correctly made. For the
