OPERATION
Odd Pixel Adjustment
NOTE: For sources with Color Space set to RGB only.
When using certain RGB sources with static
images, you may need to adjust the normal gain
or offset of odd pixels in relation to even in
order to smooth out very narrow (1-pixel wide)
checks or vertical stripes. These patterns signify
adjacent "on" and "off" pixels, and can be
removed as follows:
NOTES: 1) Always adjust offset before gain, since offset affects gain. 2) A value of 128 repre-
sents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment eliminates "1 pixel
on, 1 pixel off" patterns only, not any type of larger patterns.
Advanced Color Temperature
Select the Advanced "Color Temp" option if you want to apply, alter, add, or copy a color tem-
perature, or if you want to use an unaltered factory default color temperature.
By default, the projector can utilize any of four calibrated factory-set color temperatures: 3200,
5400, 6500 or 9300 (expressed in degrees Kelvin). For most applications, these temperatures
will display accurate and realistic colors from a variety of sources. They can be selected at any
time in either the Image Settings menu or in the Advanced Color Temperature menu.
1. Use an external grayscale test pattern of some kind (make sure it has both dark grays
and light grays).
2. Make sure the image is displayed in its native resolution, i.e. with No Resizing.
3. Display a single color - choose through the "Color Enable" menu option or use the
key shortcuts shown on the back of the remote keypad.
Func
4. Examine an area of darkest gray (but not black). If there is a 1-pixel wide pattern
present, adjust "Odd Pixel Adjustment" offset for the current color. Stop when the pat-
tern disappears and the area is smooth.
5. Examine an area of lightest gray (but not white). If there is a 1-pixel wide pattern
present, adjust "Odd Pixel Adjustment" gain for the current color. Stop when the pattern
disappears and the area is smooth.
6. Repeat for each color, adjusting offset then gain for each.
