◦User a white point that can be adjusted according to your personal prefer- ences as follows:
▪press the number 3 on the remote control to activate the User column
▪position the white point within the CIE chromaticity diagram
Note: To accurately set the Primaries and White Point you will need access to special- ized color measuring equipment and also the knowledge to use such equipment. Al- ternatively, contact the SIM2 Authorized Dealer where you purchased your product and ask them to arrange for an ISF certified calibrator to set up your projector.
Gamma Correction
Determines the projector response to the gray scale, emphasizing or attenuating the different grades of brightness (blacks, dark, medium and light grays, whites) in the projected image. Choose the setting that is appropriate to the type of video source, the ambient lighting and your subjective preferences. The available settings are:
•Natural the default preset curve, appropriate for most situations
•Dynamic the preset curve that increases the detail in the dark areas of the im- age
•Parametric that lets you select the coefficient that determines the curve. Coefficient values smaller than 2.2 emphasize the detail of dark images, while reducing overall contrast. Values larger than 2.2 increase overall contrast, but reduce the detail of dark areas. For the most common video sources, if you
set the parameter to 2.2 you obtain pleasant and
Overscan
Removes the outer edges of the image and magnifies the remaining portion of the im- age to fill the display area. It is useful with sources that output images with imperfec- tions around their borders.
Position
Use this adjustment to position the image vertically and horizontally. These paramet- ers do not normally require adjustment because the projector checks the input signal and automatically sets the most suitable values. However, if the image is not perfectly centered it may prove useful to make the projector repeat the input signal analysis and image positioning, activating the automatic adjustment procedure with the Auto key on the remote control. When this procedure is requested it is helpful to have a white or light colored background in the current picture on the screen.
Frequency/Phase
These adjustments, available for progressive signals and for signals from a PC, ensure correspondence between the number of pixels making up the signal and the number of pixels that make up the projected image. The projector usually detects the most suitable values but, if the image is disturbed (loss of resolution between equidistant vertical bands or instability and lack of detail in thin vertical lines), you can press Auto on the remote control to activate the automatic adjustment function. If the automatic procedure fails to achieve the required effect, enter the Frequency and Phase values
