DOT CLOCK

If you have interference patterns of the projected image, which is sometimes referred to as moire or noise, you can minimize it by pressing I H to adjust the clock frequency. (Available with signals of RGB only)

Settings

REALTIME KEYSTONE

If the projector is aligned non-perpendicularly to the screen, or if the projection screen has an angled surface, the keystone will be corrected automatically. Press I H to select the required setting.

ON: Active

OFF: Deactive

KEYSTONE

If you need to correct the angle of the projection even when the REALTIME KEYSTONE is activated, you can correct the keystone manually.

Image Operation

NOTE:

•You can correct the distortion ± 30 degrees from the plane. For a better quality image, installing the projector with a minimum of distortion is recommended.

•The distortion of the Main menu screen is not correctable.

•The result of the keystone correction will affect the aspect ratio and the size of the image.

POSITION

You can move the projected image for fine adjustment. Press I H to move horizontally and F G vertically. (Available with signals of VIDEO/S-VIDEO/RGB/YPBPRonly)

CLOCK PHASE

If you require further adjustment for the same reason as the DOT CLOCK adjustment, you can fine adjust the timing of the clock. Press I H to adjust. (Available with signals of RGB/YPBPR only)

NOTE:

•If the projecting signal’s dot clock frequency is higher than 108 MHz, the adjustment may not make a difference. See “List of compatible signals” on page 44.
