[IMAGE OPTIONS]

Adjusting Clock and Phase [CLOCK/PHASE]

This allows you to manually adjust CLOCK and PHASE.

4. Using On-Screen Menu

CLOCK ������������������� Use this item to fine tune the computer image or to remove any vertical banding that might appear� This function adjusts the clock frequencies that eliminate the horizontal banding in the image�

This adjustment may be necessary when you connect your computer for the first time�

PHASE ������������������� Use this item to adjust the clock phase or to reduce video noise, dot interference or cross talk� (This is evident when part of your image appears to be shimmering�)

Use [PHASE] only after the [CLOCK] is complete�

46

Adjusting Horizontal/Vertical Position [HORIZONTAL/VERTICAL]

Adjusts the image location horizontally and vertically.

4. Using On-Screen Menu

- An image can be distorted during the adjustment of [CLOCK] and [PHASE]. This is not malfunction.

- The adjustments for [CLOCK], [PHASE], [HORIZONTAL], and [VERTICAL] will be stored in memory for the current signal. The next time you project the signal with the same resolution, horizontal and vertical frequency, its adjustments will be called up and applied.

To delete adjustments stored in memory, from the menu, you select [RESET] → [CURRENT SIGNAL] or [ALL

DATA] and reset the adjustments.

Selecting Overscan Percentage [OVERSCAN]

This allows you to set the appropriate overscan for an incoming signal.

AUTO ��������������������� Display an appropriately overscanned image (factory setting)�

OFF ������������������������ Does not overscan the image�

ON ������������������������� Overscans the image�

Projected image

Overscaned by 10%

NOTE:

• The [OVERSCAN] item cannot be selected when VIDEO signals are used or when [NATIVE] is selected for [ASPECT RATIO].

Selecting Aspect Ratio [ASPECT RATIO]

The term “aspect ratio” refers to the ratio of width to height of a projected image.

The projector automatically determines the incoming signal and displays it in its appropriate aspect ratio.

• This table shows typical resolutions and aspect ratios that most computers support.

Options Function

The projector will automatically determine the incoming signal and display it in its aspect ratio. ( →

next page )

The projector may erroneously determine the aspect ratio depending on its signal. If this occurs, select the appropriate aspect ratio from the following.

The image is displayed in 4:3 aspect ratio.

The image is displayed in 16:9 aspect ratio.

The image is displayed in 15:9 aspect ratio.

The image is displayed in 16:10 aspect ratio.

The image of a letterbox signal is stretched equally in the horizontal and vertical directions to fit the screen. Parts of the displayed image are cropped at the top and bottom edges and therefore not visible.

The projector displays the current image in its true resolution when the incoming computer signal has a lower resolution than the projector’s native resolution.

[ Example] When the incoming signal with the resolution of

800 × 600 is displayed:

NOTE:

• When a non-computer signal is displayed, the [NATIVE] is not available.

• When a signal with a higher resolution than the projector’s native resolution is displayed, [NA-

TIVE] is not available.

Sample image when the aspect ratio is automatically determined

NOTE: To display a letterbox signal properly, select [LETTERBOX].

NOTE: To display a squeezed signal properly, select [16:9].

TIP:

• The term “letterbox” refers to a more landscape-oriented image when compared to a 4:3 image, which is the standard aspect ratio for a video source.

The letterbox signal has aspect ratios with the vista size “1.85:1” or cinema scope size “2.35:1” for movie film.

• The term “squeeze” refers to the compressed image of which aspect ratio is converted from 16:9 to 4:3.

Turning on Noise Reduction [NOISE REDUCTION]

This function allows you to select the level of noise reduction.

The projector is set to the optimized level for each signal at the factory.

Select your preference item for your signal when video noise is noticeable.

The options are [OFF], [LOW], [MEDIUM], and [HIGH].

NOTE: This feature is not available for the RGB signal. Noise reduction set to off gives best image quality by way of higher bandwidth.

Noise reduction set to on softens the image.
