Mode button. If the Analog Offset Base and Analog Gain slider controls are enabled, then the display model supports

adjustment of the settings via software, and skip to step 6. Otherwise the controls must be adjusted via the OSD.

4. Use either an IR remote or the IR Remote emulation (see other tab) to display the OSD. If the Expert Mode OSD has

been successfully enabled, the OSD will show “EXPERT” in the top right corner. The Expert OSD menu is accessed by

navigating to the right-most menu, then navigating one more step right.

5. On the EXPERT OSD menu, navigate to the AUTO BIAS GAIN control.

6. In the software, click the Black LUT button to load the special LUT. This process will take less than 1 minute. When

completed the screen may start to display some video noise - this is normal.

7. The aim of the next step is to adjust the red, green and blue Offset Base (Bias) settings correctly until the screen is

full of bright white noise. If the slider controls are available, adjust the Analog Offset Base controls, otherwise the the

OFFSET BASE 01 (red), OFFSET BASE 02 (green), and OFFSET BASE 03 (blue), values on the OSD.

Use the IR Remote or IR Remote emulation feature to adjust the OFFSET BASE values up and down.

As the setting value nears the ideal setting, the color being adjusted will start to show as noise. The red, green, and blue

noise will combine to make white noise.

The following table shows how the screen color will change as the OFFSET BASE values are adjusted:

SCREEN COLOR OFFSET BASE 01 Value OFFSET BASE 02 Value OFFSET BASE 03 Value

Black INCORRECT INCORRECT INCORRECT

Red Noise OK INCORRECT INCORRECT

Green Noise INCORRECT OK INCORRECT

Blue Noise INCORRECT INCORRECT OK

Yellow Noise OK OK INCORRECT

Cyan Noise INCORRECT OK OK

Magenta Noise OK INCORRECT OK

White Noise OK OK OK

Note that screen may be very noisy and it may difcult to get a pure white screen. Adjust each control until as pure a

white screen as possible can be obtained.

Important: Do not adjust the OFFSET 01, 02, or 03 settings.
