In the situation where you are projecting onto a colored surface such as a painted wall 

which may not be white, the Wall Color feature can help correct the projected picture’s 

color to prevent possible color difference between the source and projected pictures.

To use this function, press 

 to open the pop-up menu in one of the computer, iPhone/

iPad, composite video, component and HDMI/MHL modes. Select Wall Color and press 

/ 

 to select a color which is closest to the color of the projection surface. There are 

several precalibrated colors to choose from: Light Yellow, Pink, Light Green, Blue, and 

Blackboard.

According to the detected signal type, there are some user-definable functions available 

when User mode is selected. Based on your needs, you can make adjustments to these 
functions by highlighting them and pressing 

/ 

 on the projector or remote control.

The higher the value, the brighter the image. And the 

lower the setting, the darker the image. Adjust this 

control so the black areas of the image appear just as 

black and that detail in the dark areas is visible.

The higher the value, the greater the contrast. Use this 

to set the peak white level after you have previously 

adjusted the Brightness setting to suit your selected 

input and viewing environment.

Lower setting produces less saturated colors. If the setting is too high, colors on the image 

will be overpowering, which makes the image unrealistic. Color is only adjustable under 

analog video sources such as composite video and component video sources.

The higher the value, the more reddish the picture becomes. The lower the value, the 

more greenish the picture becomes. Tint is only adjustable under video and S-video 

sources with video signal in NTSC or SECAM format.

The higher the value, the sharper the picture becomes. The lower the value, the softer the 

picture becomes. Sharpness is only adjustable under analog video sources such as 

composite video and component video sources.

There are a number of options available for color temperature* settings which vary 

according to the signal type selected.

There are many different shades that are considered to be "white" for various purposes. 

One of the common methods of representing white color is known as the “color 

temperature”. A white color with a low color temperature appears to be reddish white. A 

white color with a high color temperature appears to have more blue in it.
