The following tips may help you optimize your display: Adjust the computer's graphics card so that it outputs a 1280 x 1024 @ 60Hz video signal to the LCD display. (Look for instructions on changing the refresh rate in the graphics 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 Image Adjust automatically sizes, centers, and fine tunes the video signal to eliminate waviness and distortion. Press the [2] button to execute Auto Image Adjust. 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). 6500K - Adds red to the screen image for warmer white and richer red. 5400K - Adds green to the screen image for a darker color.

Control

Explanation User Color - Individual adjustments for red (R), green (G), and blue (B). 1. To select color (R, G or B) press button [2]. 2. To adjust selected color, press or. 3. When all color adjustments are complete, press button [1] twice. Information displays the timing mode (video signal input) coming from the graphics card in the computer, the LCD model number, the serial number, and the ViewSonic website URL. See your graphics cards user guide for instructions on changing the resolution and refresh rate (vertical frequency). NOTE: VESA 1280 x 1024 @ 60Hz (recommended) means that the resolution is 1280 x 1024 and the refresh rate is 60 Hertz.

Manual Image Adjust

H./V. Position (Horizontal/Vertical Position) moves the screen image left or right and up or down. Press button [2] to toggle between Horizontal and Vertical. The Horizontal setting moves the screen image to the left or to the right. The Vertical setting moves the screen image up and down. H. Size (Horizontal Size) adjusts the width of the screen image. Fine Tune sharpens the focus by aligning text and/or graphics with pixel boundaries. NOTE: Try the Auto Adjust function before using the Fine Tune control. Sharpness adjusts the clarity and focus of the screen image.
Explanation Setup Menu displays the menu shown below:
Language Select allows the user to choose the language used in the menus and control screens. Resolution Notice advises the optimal resolution to use.
OSD Position allows the user to move the OSD menus and control screens. OSD Timeout sets the length of time the OSD screen is displayed. For example, with a 15 second setting, if a control is not pushed within 15 seconds, the display screen disappears. OSD Background allows the user to turn the OSD background On or Off. Memory Recall returns the adjustments back to factory settings if the display is operating in a factory Preset Timing Mode listed in the Specifications of this manual.

4. Circuit Description

Electronic Circuit Theory
1 Switching Mode Power Supply 1.1 AC Current Input Circuit P801 is a connector for connecting AC Power. F801 is a fuse to protect all the circuit. AC input voltage is from 90V to 264V. R820 and R821 joined between two inputting main circuit to prevent man from shock. L801 is used to clear up low frequency wave. C801 and C806 are used to discharge the waves that L801 produced. High frequency waves are damped by C801 and C806. D801 is a rectifier which composed of 4 build-in diodes, it inverts AC to DC. 1.2 High Voltage to Low Voltage Control Circuit C805 is used to smooth the wave from rectifier. IC802 is a highly integrated PWM controller, which build-in a power MOSFET. When rectified DC high voltage is applied to the DRAIN pin during start-up, the MOSFET is off initially, and the CONTROL pin capacitor is charged through a switched high voltage current source connected internally between the DRAIN and CONTROL pins. When the CONTROL pin voltage Vc reaches approximately 5.8V, the control circuitry is activated and the soft-start begins. The soft-start circuit gradually increases the duty cycle of the MOSFET from zero to the maximum value over approximately 10ms. If no external feedback/supply current is fed into the CONTROL pin by the end of the soft-start, the high voltage current source is turned off and the CONTROL pin will start discharging in response to the supply current drawn by the control circuitry. Resistor R803, R807, R824 and R825 are for line over voltage shut-down (OVP) and line under-voltage detection (UVP).Resistors R801, R805, R822, and R823 are for external current limit adjustment, and used to reduce the current limit externally to a value close to the operating peak current of primary about 1.35A. The mean is power will protected when the primary current over about 1.35A. When PWM is turned off, the main current flow will be consumed through D804 and ZD802, This will prevent MOSFET which built-in IC802 from being damaged under large current impulse and voltage spike. D806 and C815 provide internal Auxiliary current to CONTROL pin during normal operation. In addition, error amplifier and feedback current to the CONTROL pin are for duty cycle control. 1.3 DC_5V and DC_14V Output Circuit For DC 5V, D805 is used to rectify the inducted current. R806 and C811 are used to store energy when current is reversed. The parts including C812, C814, C822, C821, B801 and L803 are used to smooth the current waves. For DC 14V, D803 is used to rectify the inducted current. R802 and C802 are used to store energy when current is reversed. The parts including C808, C810 and L802 are used to smooth the current waves. 1.4 Feedback and OVP Protect Circuit Pin R of IC803 is supplied 2.5V stable voltage. It is connected to 5V and 14V output through R811, R810 and R818. R811, R810 and R818 are output sampling resistor. When the sampling voltage more than 2.5V or less than 2.5V, feedback current of IC802 will change, this can change the voltage from transformer T801. For 5VDC output OVP, ZD803 is a zener diode, when 5V output voltage becomes up to 5.6V, the zener current cause R819 voltage become up to 0.7V, Q801 is triggered and OVP starts. For 12VDC output OVP, ZD804 is a Zener Diode, when 14V output voltage becomes up to 16V, the zener current cause R819 voltage become up to 0.7V, Q801 is triggered and OVP starts. The collector current of Q801 is used to make build-in diode light. FB Current of IC802 will be changed; it can change the voltage from T801. Q802, R827, R828 and ZD801 make up of dummy loading circuit. For start-up sequence, during 5V output take place high loading first, this dummy loading circuit operated to insure 14V not be increased.

If not, please re-write EDID or upload firmware into MCU via VGA Cable. If you adjust clock and phase, please do it at the condition of Windows shut down pattern. If you confirm the R.G.B. color is normal or not, please do it under 16-grey scalar pattern. This LCM is analog interface. So if the entire screen is an abnormal color that means the problem happen in the analog circuit part, if only some scale appears abnormal color that stand the problem happen in the digital circuit part. If you check the H/V position, please use the crosshatch pattern. This LCM support more than 30 timing modes, if the input timing mode is out of specification, the picture may appears abnormally. If brightness uneven, repairs Inverter circuit or change a new panel. If you find the vertical line or horizontal line lost on the screen, please change panel.
