The following tips may help you optimize your display:
Adjust your computer's graphic card so that it outputs a video signal 1600 x 1200 @ 60 Hz to the LCD display. (Look for instructions on “changing the refresh rate” in your graphic card's user guide.)
If necessary, make small adjustments using H POSITION and V POSITION until the screen image is completely visible
. (The black border around the edge of the screen should barely touch the illuminated “active area” of the LCD display.)

or graphic characters.
Sharpness
adjusts the clarity and focus of the screen image.
Scaling
adjusts the video input signal to the screen size other
than 1600 x 1200 using the following options.
1:1
adjusts the video signal so that the height and width of the
picture are the same.
Fill all
adjusts the video signal to fill the screen.
Fill Aspect Ratio

1. Power supply (DC/DC Converter):
1.1 IC251 BA9741F is a two-channel switching regulator controller that uses PWM method. For DC to DC conversion for step-down. It converts a 12V DC into regulated and stable output voltage of 5V.
1.2 Regulator: IC252, IC253, IC254, IC255 function is to convert 5V into regulated and stable O/P of 3.3V and 2.5V. IC252 converts 5V to 2.5V; converts 5V to 3.3V; IC253, IC254, IC255.
2. DDC data select:
2.1 IC601 is save D-SUB DDC data.
2.2 IC606 save DVI-A analog DDC data, IC605 save DVI-D digit DDC data. IC604 is triple 2 channel analog multiplexes / de-multiplexes, IC604 pin 10 & 11 is “Lo” select IC605 DDC data, IC604 pin 10 & 11 is “Hi” select IC606 DDC data.
3. ADC (Analog): The IC608 AD9888 is a complete 8-bit, 205MSPS monolithic analog interface optimized for capturing RGB graphics signal
from PC. The IC608 have two input source (D-SUB & DVI-A), the input source control by I
2
C from IC401 scaler.
4. TMDS (DVI): The IC609 THC63DV161 is a TMDS receiver compliant with DVI Rev. 1.0. The IC609 turn on/off control by pin 2 “DPD” from IC401 scaler.
5. Scaler: The PW166B image processor is a highly integrated “system-on-a-chip” that interfaces analog, digital, and video inputs in virtually any format to a digital projection system or multimedia display.
Any embedded SDRAM frame buffer and memory controller perform frame rate conversion. Computer images from VGA to UXGA at almost any refresh rate can be resized to fit on a fixed-frequency target display device with any resolution up to UXGA with full 24-bit color.
The PW166B includes advanced second generation image scaling that provides completely programmable, horizontal and vertical image scaling.
The PW166B also includes advanced second-generation sync decoding which provides full support for a wide variety of sync types. This includes interlaced, progressive, sync-on-green, and TMDS DE (Data Enable) only.
An integrated OSD controller provides bit-mapped based OSD with 16 colors from a 64K color palette. The OSD controller supports transparent and translucent functions.
The Graphics Port (GPort) captures computer graphics inputs with very high input bandwidth through an external IC608 Analog-To-Digital converter (ADC) or IC609 digital interface receiver.
The DPort is designed to be connected directly to LVDS (IC501, IC502). The output timing is fully programmable and is independent of the input timing. An on-chip 80x86 microprocessor with custom features for image processing applications is provided. Built in port interrupts,
General Purpose I/O (GPIO), UART, IR Decoders, Timers and PWM Generator provide a full featured hardware base to build on.
6. LVDS Transmitter: The IC501, IC502 transmitter converts 28 bits of CMOS/TTL data into LVDS (Low Voltage Differential Signaling) data stream.
A phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link.
7. USB HUB Controller: IC951 is a high speed USB HUB controller, this single-chip device incorporates one upstream and four downstream USB
transceivers. IC951 CY7C65640 includes interface signals for external port power switches. The power switching and over-current detection
of downstream ports is managed by control pins connected to an external power switch device by IC952 & IC953. IC954 is an EEPROM VID & PID configured.
