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 
screen by two scans (one for odd lines 
and one for even lines) is input, progres-
sive processing is required. When the pro-
gressive function is turned off, one screen 
is displayed using image signals per inter-
lace signal, deteriorating the vertical reso-
lution of the image. When the progressive 
function is turned on, one screen is dis-
played using image signals per two inter-
lace signals, improving the vertical 
resolution of the image. Turn off the pro-
gressive function when flickering and hori-
zontal lines are noticeable on a fast-
moving picture.
A parameter that shifts the reproduction 
range of a brightness signal from black to 
white within an image signal toward the 
higher or lower level of brightness. The 
reproducibility of the dark tone is mainly 
changed. Since you can adjust the offset 
for each RGB color in this projector, you 
can also adjust colors.
The offset is normally adjusted with the gain.
A value that represents the related color in 
a light source in general. In this projector, 
the color temperature is used to adjust the 
RGB color balance for the projected 
image to correct the related color influ-
ence by the ambient light. If you increase 
and decrease the color temperature, white 
changes to blue and red, respectively. You 
can set the color temperature in the [Color 
adjustment] menu if [Photo] has been 
selected for [Image mode].
Lightning environment around the projec-
tor. You can correct and project an image 
more appropriately according to the ambi-
ent light on the screen via the setting of 
[Ambient light] if you have selected 
[Photo] for [Image mode].
A tone adjustment system used during 
projection of image data. The gamma cor-
rection function works effectively when 
portions of an image are obscure because 
they are too light or dark.
This projector supports manual gamma 
correction and dynamic gamma correction 
which performs the gamma correction 
automatically.
