Typical Test Pattern For Adjusting Sharpness - Planar PD520 Owner's Operating Manual

Sharpness: "Sharpness" is the amount of high-frequency detail in the image. To
adjust sharpness, select Sharpness from the Image Adjust menu and press
ENTER. On your external test pattern source, select a pattern like the one shown
in Figure 4-5. Adjust as needed, looking for white edges around the transitions
from black to gray and different sized lines in the "sweep" patterns at the top
and bottom. Lower the sharpness setting to eliminate them.

Color Temperature: To select a color temperature setting, select Color Temp.
from the Image Adjust menu and press ENTER. (Color temperature defines the
"color of gray.") The choices are 5400K, 6500K, 8500K and Custom. The default
setting, 6500K, is appropriate for most situations. Higher settings produce a
"bluer" picture; lower ones impart a reddish hue to the image.
Each color temperature setting has six (6) "white balance" parameters
associated with it (two each for red, green and blue). These are described later
in this section; refer to White Balance on page 39.
Gamma: The Gamma control determines how gray shades are displayed
between minimum input (black) and maximum input (white) for all signals. A
good gamma setting helps to optimize blacks and whites while ensuring smooth
transitions for the "in-between" values utilized in other grays.
Unlike brightness and contrast controls, Gamma allows you to lighten or darken
the overall tone of your images without changing the extremes. All images will
be more vibrant while still showing good detail in dark areas.
The default Gamma setting of 2.2 is appropriate for most typical home theater
environments.
