Contrast
- Contrast is the difference in brightness between lightest
and darkest tones in a picture. A picture with too much contrast has
highlights (lighter tones) that are too bright and no detail and shadow
areas that are too black. A picture with too little contrast looks dull,
with no true blacks and more grayish highlights. Different water
clarities coupled with the amount of light available will affect the
contrast. Adjust the contrast to the desired setting for the best overall
picture.
Brightness
- Use the brightness adjustment to change the overall
brightness of a picture. You can lighten a picture that's too dark,
or darken one that's too light. Different lighting conditions and
water clarity will affect the brightness of the picture. By adjusting
the brightness, the backlight of the monitor will increase making
the picture brighter. This can be helpful when viewing the VS820
outdoors during daylight hours Adjusting the brightness can make the
monitor easier to see.
Sharpness
- Sharpness is the amount of high-frequency detail
in the image. Adjust the sharpness according to personal
preference.
(note: increasing the contrast can give an
impression of increased sharpness, so try this first).
Color
- Increasing the color saturation with a black and white monitor
will increase the darkness of the blacks and make the picture look
darker overall. Decreasing the color saturation will make the blacks
and darker colors look washed out and gray.
