Gamma Selection ➤ The normal gamma setting of 2.2 is correct for almost all signals and conditions. If excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. This will improve contrast while maintaining good details for blacks. Conversely, if the image is washed out and unnatural, with excessive detail in black areas, increase the setting. Again, good gamma improves contrast while maintaining good details for blacks and whites.

SD Enhance ➤ The SD Enhance menu gives you options for improving the quality of standard-definition, 480i images. (For 480p and higher-definition images, the controls in this menu are disabled.) Keep in mind that these controls add frequencies that are not present in the original signal, and may make images appear “noisy” if misused.

H Enhance/V Enhance: These controls can improve the apparent horizontal and/or vertical resolution of the image.

Chroma Enhance: This control adds chroma (color information) to the input signal and can make colors appear more vibrant and saturated.

H Threshold/V Threshold/Chroma Threshold: Set these to +11 or higher to activate the enhancement controls described above. Generally, the higher the threshold, the more noticeable the enhancements you make will be.

RVR Adjust ➤ Use the RVR Adjust control to increase or decrease the Reflectance Volume Regulation setting. RVR lets you control the aperture or iris size (the physical opening through the lens; similar to an “f-stop” on a camera). Doing so allows you to optimize brightness and contrast according to the amount of ambient light in the viewing area.

Use a higher setting for rooms with lots of ambient light. Use a lower setting for more “theater-like” viewing conditions (little or no ambient light).

Image Over Scan ➤ Image Over Scan 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.

Select from 1% to 10% of Over Scan, as desired.

For HDTV, DVDs and other video sources, Over Scan is generally not necessary or desirable.
