in the [Image mode] setting, the projector 
can project the best-quality image con-
forming to the sRGB Standard.

Appendix
The aspect ratio is the ratio of the horizon-
tal dimension (width) to the vertical dimen-
sion (height) of a screen. It is expressed 
as width : height.
The following aspect ratios are normally 
used in Computer or AV equipment.
[4:3]
The aspect ratio for SXGA+ (1400 x 1050) 
and XGA (1024 x 768) display resolution in 
PC or for the traditional television screen.
The aspect ratio for this projector is 4:3.
[5:4]
The aspect ratio for SXGA (1280 x 1024) 
display resolution.
[16:9]...

Number of dots in each resolution
If you select SXGA+ (1400 dots x 1050 
dots) as the display resolution for the con-
necting computer, this projector can 
project high-resolution images. If your 
computer does not have the SXGA+ 
option, select the maximum resolution 
among the selectable options.
An image display system used to display 
the entire screen per scan. For an inter-
lace signal (video signal) that displays one

Appendix
A parameter that adjusts the reproduction 
range of a brightness signal from black to 
white within the image signal to naturally 
reproduce it on the screen. The reproduc-
ibility of the bright tone is mainly changed. 
Since you can adjust the gain for each 
RGB color in this projector, you can also 
adjust colors. The gain is normally 
adjusted with the offset.
A memorized color is a color in our mem-
ory. The memorized color such as blue for 
the sky is more vivid than the real...

tics of the LCD panel. 
* Using the projector continuously for an extended period of time may accelerate the deterioration of optical parts.
