Contrast: Refer to Contrast on page 53.

Brightness: Refer to Brightness on page 52.

Color: Refer to Color Saturation on page 53.

Tint: Refer to Tint on page 54.

Sharpness: Refer to Sharpness on page 55.

Color Temp.: To adjust the color temperature, select Color Temp. from the Picture Adjust 
menu. (Color temperature defines the “color of gray.”) Press 

 or 

 to select 5500, 6500, 

7500, 8500, 9300 or 10500. In most cases, 6500 or 7500 will produce the most realistic colors. 
Higher settings produce a “bluer” picture; lower ones cause the image to appear more red.

White Balance: Select White Balance from the Picture Adjust menu to choose a white 
balance preset (or “gamma curve”) to store in the currently-selected picture memory. For 
more information on white balance presets, refer to White Balance on page 68. 

VAC: Iris: Select VAC: Iris from the Picture Adjust menu to increase or decrease the aperture 
or iris size (the physical opening through the lens; similar to an “f-stop” on a camera). Doing 
so allows you to optimize brightness and contrast according to the amount of ambient light 
in the viewing area. 

Select High Brightness or Theater for rooms with lots of ambient light. Select CRT Emulation 
for more “theater-like” viewing conditions (little or no ambient light). 

Lamp Power: Select Lamp Power from the Picture Adjust menu to adjust the lamp output 
level. You can choose to run the lamp as bright as possible (220W; this is the default setting) 
or you can choose the lower setting (180W). Generally, lower lamp output can prolong the 
life of the lamp, but decreases brightness.
