OPERATION

DMD Odd Pixel

NOTE: For sources with Color Balance 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 pat- terns signify adjacent “on” and “off” pixels, and can be removed as follows:

DMD Odd Pixel Menu

1.Use an external grayscale test pattern of some kind (make sure it has both dark grays Func 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 “DMD Enable” menu option or use the key shortcuts shown on the back of the remote keypad.

4.Examine an area of darkest gray (but not black). If there is a 1-pixel wide pattern pres- ent, adjust “DMD Odd Pixel” offset for the current color. Stop when the pattern disap- pears and the area is smooth.

5.Examine an area of lightest gray (but not white). If there is a 1-pixel wide pattern pres- ent, adjust “DMD Odd Pixel” 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.

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) DMD Odd Buffer 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 Adjustments menu or in the Advanced Color Temperature menu.
