[3D SETTINGS] menu ENGLISH - 71 Settings [3D VIEWING MONITOR] In the 3D video the depth of field effects in front of and into the screen are adjusted while confirming on the monitor display. 1) Press the ◄► buttons to select [MODE1] - [MODE3], and press the button. z The parallax adjustment monitor is displayed. The display content of each mode is described below. 2) Press the ▲▼ buttons to select the optimum parallax. z Press the button to return to pre-adjustment settings. z Press the button to freeze and unfreeze. 3) Press the button. 4) When you have finished making adjustments, press the button to return to [3D SETTINGS]. The display content of each mode in the parallax adjustment monitor is as follows. [Mode1] Displays the parallax of the entire image at the bottom of the projection screen. [Mode2] Displays the maximum parallax of the entire image in one dimension. [Mode3] Displays the parallax of the entire image by superimposing on the image. (The image is in monochrome signals, and only the parallax is colored.) Attention z If the red line of the in front of screen parallax descends below the area demarcated by the reference line (white dashed line) and the lower maximum line (white solid line), or if the blue line of the into screen parallax ascends above the area demarcated by the reference line (white dashed line) and the upper maximum line (white solid line), then make sure to watch from a large enough distance from the screen or stop watching. For explanation about each line, refer to the following explanation for [Mode 1]. The lines on the parallax adjustment monitor in [Mode1] display the following content: White (dashed line) Default display for video without parallax Blue Displays the into screen parallax Red Displays the in front of screen parallax White (solid line) Displays an estimate for parallax of general 3D video Into screen parallax In front of screen parallax ADJUST··ENTER : APPLY··DEFAULT : RESET··FUNCTION : FREEZE This indicates the maximum estimate in front of screen parallax while measuring.

Note z In [Mode2] and [Mode3], the display position can be moved left and right with the ◄ ► buttons. z In [Mode3], the detection level of the parallax can be changed with the button. Low level and high level can be switched by pressing the button each time. The default setting is high level. z In the cases such as 3D video input has a very large parallax or in dark scenes, the correct parallax may not be detected. z If the depth of field effects in front of and into the screen for the 3D video parallax are set stronger than the target, this may cause some individuals to feel extreme discomfort or fatigue. Adjust the parallax so as to not exceed target displaying (white (solid line)). z When an action is performed such as switching the power off and on, switching input, or switching the signal, the parallax adjustment set becomes inactive. z When adjusting the parallax using the [3D VIEWING MONITOR], the ends on both sides of the video are masked. Also note that the aspect size is changed.
