#
Component 
For SDTV and EDTV resolutions, uses the YUV STD. For all other resolutions YUV HD is used.
Input Locking
Use this function to specify the frequency of the image input signal. You can let the projector 
determine the optimal projection frequency or force the projector to project image at the frequency 
you specify.
#
Auto 
  The present value for this function is Auto. If you specify vertical refresh frequency from the 
input device to be between 48~62Hz, the projector will automatically lock the frequency of the 
input signal so that both signal input and output will be refreshed at the same frequency in order 
to achieve optimal image output. If the frequency of the input signal falls between 24~31Hz, the 
projector will automatically double the vertical refresh frequency. If the frequency of the input 
signal falls between 31~48Hz or exceeds 62Hz, the projector will automatically set the frequency 
to 60Hz.
#
50Hz  
 Choose this option to set image output frequency at 50Hz.
#
60Hz  
 Choose this option to set image output frequency at 60Hz.

IMAGE
Contrast
Use  to adjust the contrast of the projected image. You can connect the projector to an external 
image source to display an image resembling the one shown below for adjustment. It is recommended 
that you adjust the projected image according to the results shown below so that the brightness of the 
spectrum remains constant throughout and achieve maximum contrast between black and white. 
The following image illustrates the results of direct contrast adjustment using a random image: 
 Lowered contrastEnhanced contrast  Original image

Brightness
Use  to adjust the brightness of the projected image. You can connect the projector to an external 
image source to display an image resembling the one shown (PLUGE, Picture Line-Up Generation 
Equipment) for adjustment. Although there are numerous versions of PLUGE image, they are typically 
comprised of blocks of black, white and gray on top of a black background. 
 
Contrast, Brightness, Saturation and Tint are inter related options that affect

Sharpness
The adjustment of sharpness primarily changes the value of high frequency detail. You can  connect 
the projector to an external image source to display an image resembling the one shown below to 
adjust the image sharpness.
 
The following image illustrates the results of direct sharpness adjustment using a random image: 
 
 Reduced sharpnessEnhanced sharpness  Original image (Value = 100)
Noise Reduction
Use  to adjust the noise of the projected image. This function is suitable for the elimination of 
image noise from interleaving SD input. Generally speaking, reducing image noise will lower the 
value of high frequency detail and make the image appear more mellow.

Color Temperature
You can choose from 3200K, 5400K, 6500K, 9300K and Native.
Color temperature refers to the change in light color under different energies that is perceived by the 
naked eye. The change of color temperature from low to high for visible light goes from orange red  
white  blue

LAYOUT
Zoom
Due to the fact that some consumers may still be using older television systems, some TV programs 
may not display the edges of the image. Use this function to hide the image edge by choosing one of 
the following three options:
#
Off 
 Setting it to off makes no change to the projected image. 
#
Crop 
  Setting it to "Crop" will add two "masks" equivalent to 3% of horizontal resolution on either side of 
the image and two similar masks above and below the projected image. 
#
Zoom 
  You can use this function to enlarge the image's horizontal resolution over the 106% of the  default 
aspect ratio. Any portion that exceeds the original image will be cropped. 
When you set aspect ratio to "Native" or "Unscaled" , be sure to set Zoom to "Off " or "Crop".
