The down arrow decreases Contrast, up arrow increases Contrast.
The line at the bottom of the screen tells you what you can do next: select the Brightness control or Exit.
To adjust the control, press the up or down buttons. To save the adjustments and exit the menu, press button [1] twice.
The following tips may help you optimize your display: Adjust your computer's graphic card so that it outputs a video signal 1280 x 1024 @ 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.)

Main Menu Controls

Adjust the menu items shown below by using the up and down buttons. Control Explanation
Auto 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 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 options: preset color
temperatures and User which allows you to adjust red (R), green (G), and blue (B). The factory setting for this product is 6500K (6500 Kelvin).
User Individual adjustments for red, green, and blue. 5400K Adds blue and green to the screen image for a darker

color.

6500K Adds red to the screen image for warmer white and
richer red. Default setting.
9300K Adds blue to the screen image for cooler white (used
in most office settings with fluorescent lighting).
To select color (R, G or B) press button [2]. To adjust selected color, press or. When you are finished making all color adjustments, press button [1] twice.
Information displays the timing mode (video signal input)
coming from the graphics card in your computer. See your graphic cards user guide for instructions on changing the resolution and refresh rate (vertical frequency). VESA 1280 x 1024 @ 60 Hz (recommended) means that the resolution is 1280 x 1024 and the refresh rate is 60 Hertz.

Control

Explanation

Image Adjust

The Image Adjust controls are explained below:
H./V. Position adjusts horizontal and vertical position of the
screen image. You can toggle between Horizontal and Vertical by pressing button [2]. Horizontal moves the screen image to the left or to the right. Vertical moves the screen image up and down.
H. Size (Horizontal Size) adjusts the width of the screen image.
Vertical size is automatic with your LCD display.
Fine Tune sharpens focus by aligning the illuminated text and/
or graphic characters. Try the Auto Adjust (see page 9) before using the Fine Tune control.
Sharpness adjusts the clarity and focus of the screen image. Setup Menu displays the menu shown below:
The Setup Menu controls are explained below:
Language Select allows you to choose the language used in the
menus and control screens.
Resolution Notifier advises the optimal resolution to use.
OSD Position allows you to move the on-screen display menus

and control screens.

OSD Timeout sets the length of time an on-screen display
screen is displayed. For example, with a 15 second setting, if a control is not pushed within 15 seconds, the display screen disappears.
Memory Recall returns adjustments to the original factory
settings if the display is operating in a factory Preset Timing Mode listed in this user guide.

4. Circuit Description

A. DC-DC CONVERTER The DC-DC converter converts the 12V input voltage to 5V for panel use, and 3.3V and 1.8V for controller use. It consists of a PWM IC (LM2596), flywheel Diode (B340), buck choke (L108), and capacitor C173. I102 (LM2596) is a PWM generator working at 150KHz. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault condition. B. Scaling controller The ADC is used to convert RGB analog signal to digital signal that scaling chip can acknowledge. The HSYNC input receives a logic signal and provides the frequency reference for pixel clock generation. The scaling IC converts the input signal ranging from VGA to SXGA into SXGA resolution that panel can acknowledge. When power is first applied, the ADE3XXX is asynchronously reset. The uC typically programs the ADE3XXX with a number of default values and sets up the ADE3XXX to identify activity on any of the input pins. All preconfigured values and RAMs, such as line-lock PLL settings, OSD characters, LCD timing values (output sequencer), scale kernels, gamma curves, sRGB color warp, APC dithering, output pin configuration (OMUX), etc. can be preloaded into the ADE3XXX. The typical end state is that the ADE3XXX is initialized into a low power mode, ready to turn active once the power button is pressed. When the monitor has been powered on, the inputs can be monitored for active video sources. Based on the activity monitors, the uC chooses an input or power down state. Once an input source is selected, all available information on frequencies and line/pixel counts is measured for the selected source and made available to the uC. MTV312M64 The MTV312M micro-controller is an 8051 CPU core embedded device especially tailored for CRT/LCD Monitor applications. It includes an 8051 CPU core, 1024-byte SRAM, 14 built-in PWM DACs, VESA DDC interface, 4-channel A/D converter, and a 64K-byte internal program Flash-ROM. A CMOS output pin means it can sink and drive at least 4mA current. It is not recommended to use such pin as input function. An open drain pin means it can sink at least 4mA current but only drive 10~20uA to VDD. It can be used as input or output function and needs an external pull up resistor. A 8051 standard pin is a pseudo open drain pin. It can sink at least 4mA current when output is at low level and drive at least 4mA current for 160nS when output transits from low to high, then keep driving at 100uA to maintain the pin at high level. It can be used as input or output function. It needs an external pull up resistor when driving heavy load devices. POWER CONFIGURATION The MTV312M can work on either 5V or 3.3V power supply system. In 5V power system, the VDD pin is connected to 5V power and the VDD3 needs an external capacitor, all output pins can swing from 0~5V, input pins can accept 0~5V input range. The ADC conversion range is 5V. However, X1 and X2 pins must be kept below 3.3V. In 3.3V power system, the VDD and VDD3 are connected to 3.3V power, all output pins swing from 0~3.3V, HSYNC, VSYNC and open drain pin can accept 0~5V input range, other pins must be kept below 3.3V. The ADC conversion range is 3.3V. C. INVERTER In order to drive the CCFLs embedded in the panel module, there is a ROYER inverter to convert the input 12V up to hundreds of AC voltage output. The inverter is formed by symmetric circuitry, in order to drive the separate lamp modules. The input stage consists of a PWM controller, buck choke, and switching MOSFET to convert DC input into AC output. The output stage consists of a tuning capacitor, transformer, and push-pull transistor pair to boost ac output up to hundreds of voltage. There is also one resister in series with the lamp for output current feedback. A 6-pin connector is the only interface to control the inverter. Pin 5/6 is 12V input, pin 1/2 is the returns, pin 3 is the control of output current, and pin 4 is the enable/disable control.
