Control Explanation
Auto Image Adjust automatically sizes, centers, and fine tunes the video signal to eliminate waviness and distortion. Press the [2] button to obtain a sharper image.
NOTE: Auto Image Adjust works with most common video cards. If this function does not work on your LCD display, then lower the video refresh rate to 60 Hz and set the resolution to its pre-set value.
Contrast adjusts the difference between the image background (black level) and the foreground (white level).
Brightness adjusts background black level of the screen image.
Color Adjust provides several color adjustment modes, including preset color
temperatures and a User Color mode which allows independent adjustment of red (R), green (G), and blue (B). The factory setting for this product is 6500K (6500 Kelvin).
sRGB-This is quickly becoming the industry standard for color management, with support being included in many of the latest applications. Enabling this setting allows the LCD display to more accurately display colors the way they were originally intended. Enabling the sRGB setting will cause the Contrast and Brightness adjustments to be disabled.
9300K-Adds blue to the screen image for cooler white (used in most office settings with fluorescent lighting).

- Check and see if it is in normal condition.
1.5.10 Dead Pixel and Line Test Signal: 1280*1024@60Hz Test Pattern: Dark and White Screen Pattern
- Check and see if there are dead pixels on LCD panel with shadow gauge and
filter film.
- The total numbers and distance of dead pixels should be compliant with the
spec.
Mura
Test Pattern: White, RGB, Black, & Grey Test Tool: 10% ND Filter
- Check if the Mura can pass 10% ND Filter.
Audio
Test Signal: Voice signal (optional, depend on model) Test Pattern: liberty
- Make sure there is audio output.
- Make sure that audio function (volume 80%) is working without noise and
resonance.
- Make sure that the sound of right and left speakers are in balance.
Check for Secondary Display Modes
Test Signal:

Page 31
720*400@70Hz; 800*600@56/60/72/75/85Hz; 832*624@75Hz, 1024*768@60/70/72/75/85Hz; 1280*1024@60/75Hz
- Normally when the primary mode 1280*1024@60Hz is well adjusted and
compliant with the specification, the secondary display modes will also be compliant with the spec. But we still have to check with the general test pattern to make sure every secondary is compliant with the specification.
All Modes Reset
After final QC step, we have to erase all saved changes again and restore the factory defaults. You should do “All Mode Reset” again.

P.S: The 1N4148 Vf=0.7V~1V can't meet LDO spec. The BAT42, Vf is OK but the If=200mA(forward current) can not meet current spec.
For RSDS and Panel VCC=12V

D704(SSM12L) Vf=0.38V and If=1A. So when system power on, the system loading is about 400mA (3.3V is about 200mA and 1.8V is about 200mA), So D35 changed from 1N4148(or BAT42) to SSM12L(schottky diode).
