Q: Why is the TV not displaying portions of the display when   
     converted? 

 

A: 

Your display might be running in “Overscan” mode (placing portions 

of the picture beyond the boundaries of the screen’s visible area).  This 

typically  occurs because VGA graphics have more display lines than the 

TV can handle.  Toggle through the H-SIZE and V-IZE settings in the 
MENU until you find the optimum setting for your application. 

 

NOTE 

The SIZE control allows the entire image to be displayed by reducing it 

and putting a crisp, black border around it.  Use this control in 

situations where edges of the image would otherwise be lost due to 
overscanning. 

 

Q:  There are noise lines on the TV picture.  How do I get rid of 

them? 

 

A: 

There are four settings in most televisions that affect the clarity of 

the display. The same adjustments can be used to improve the clarity 

of the display whether you use a converter or not.  The settings are: 

 

1.

 

BRIGHTNESS:  Typically, the brightness setting is by default too 

high.  A high brightness setting often causes the display to flicker. 

2.

 

SHARPNESS:  If the sharpness is set too high, often the result is 
what is termed “dot-crawl”, where the edges of the image appear 

to move.  Lower the sharpness to soften the edges. 

3.

 

COLOR: If the color is set too high, often the result is colors that 

bleed or appear to sparkle.  The high (purple) and low (red) 

frequency colors are most affected.  Adjust the color setting down 

to soften the colors. 

4.

 

CONTRAST:  If the contrast is set too high, often the result is 

exaggerated colors.  Adjust the contrast down to complement the 

Sharpness setting.
