When tint is decreased, the image appears redder; when it is increased the image appears 
greener. To set the tint,...

Overscan: Image Overscan pushes the outside edge of the active picture area of the video 
signal out beyond the edge of the display area. 
Some television programs are produced based on the assumption that older television sets 
may not display the outer edges of the broadcast picture area. Over scan effectively trims 
away these inactive, outer edges and enlarges the remaining portion of the image to fill the 
display area....

• Noise Filter: To apply noise filtering to the input signal, select Noise Filter from the Input 
Color menu. The Noise Filter is useful for clearing up noisy images from 480i video 
sources.

the image.

HD Format: If the characteristics of the incoming signal on the HD1 or HD2 inputs are 
known, select HD Format from the Service menu and set them as described below. Doing so 
can reduce the time it takes the VHD Controller to switch from HD to 480i signals or vice 
versa. 
This is generally not necessary unless the VHD Controller – for whatever reason – has 
difficulty determining the color space (RGB or YUV), bandwidth or...
