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.
