1. Precaution & Safety Notice

1. Caution :

No modification of any circuit should be attempted . Service work should only be performed after you are thoroughly familiar with all of the following safety checks and servicing guide line

2. Safety Check :

Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit. These voltage are exposed in such areas as the associated transformer circuits .

3. POWER SUPPLY REQUIREMENTS The external power converter for this display utilizes AC and DC cords , AC cord is detachable , but DC cord is

permanently attached . Any attempt to replace another adapter could result in serious problem on the display .

4. LEAKAGE CURRENT HOT CHECK 4-1 Plug the AC cord directly into the AC outlet. Do not use an isolation transformer during this check. 4-2 Connect a 1500 ohm , 10 watt resistor , paralleled by a 0.15uF capacitor between each metallic part and a

good earth ground

4-3 Use an AC voltmeter with 1000 ohm / volt or more sensitivity and measure the AC voltage across the

combination 1500 ohm resistor and 0.15uF capacitor. 4-4 Move the resistor connection to each exposed metallic part and measure the voltage. 4-5 Reverse the polarity of the AC plug in the AC outlet and repeat the above measurement. 4-6 Voltage measured must not exceed 1.5 volt RMS, from any exposed metallic part to the ground. A leakage

current tester may be used in the above hot check, in which case any circuit measured must not exceed 1.0

milliamp. In the case of a measurement exceeding the 1.0 milliamp value, a rework is required to eliminate

the chance of a shock hazard .

Main Menu Controls

Adjust the menu items shown below by using the up and down buttons. A. 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.

B. Contrast adjusts the difference between the image background (black level) and the foreground (white level). C. Brightness adjusts the lamps current to control the screen brightness. D. Color Adjust provides several color options: preset color temperatures and Custom User Color which allows you

to adjust red (R), green (G), and blue (B). The factory setting for this produc t is 6500K (6500° Kelvin).

sRGB ─ Standard color space proposed by Microsoft and HP. 9300K — Adds blue to the screen image for cooler white (used in most office settings with fluorescent lighting). 7500K — Adds blue to the screen image for cooler white 5400K — Adds red to the screen image for warmer white and richer red. 5000K — Adds red to the screen image for warmer white and richer red. Custom User Color — Individual adjustments for red, green, and blue. 1 To select color (R, G or B) press button [2]. 2 To adjust selected color, press or . 3 When you are finished making all color adjustments, press button [1] twice.

E. Information displays the timing mode (video signal input) coming from the graphics card in your computer. See

your graphic card’s us er 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.

F. Manual Image Adjust controls are explained below:

PIP (Picture in Picture) features are explained below:

PIP enables Picture in Picture function. PIP Position is for user to adjust the position of PIP. Press button [2] to enter the PIP H. Position and use

or to adjust the PIP horizontal position. User can press [2] to enter V. Position and use or to adjust the PIP vertical position. PIP SWAP is for user to swap the signal in main window to daughter window while the signal of daughter window will be displayed in main window.

H. Size (Horizontal Size) adjusts the width of the screen image. NOTE: Vertical size is automatic with your LCD display. 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.

Fine Tune sharpens focus by aligning the illuminated text and/or graphic characters.

Viewsonic Corporation 11 VP2030b-1 Confidential - Do Not Copy

Sharpness adjusts the clarity and focus of the screen image. This feature is disabled when the input signal is

1600x1200@60Hz analog signal.

Scaling features are explained below: Fill All - the signal will be displayed on the whole screen and wide signal will be adjusted to 4:3 ratio. Fill Aspect Ratio – the width of the signal will fit the screen horizontally while the vertical directions may

not fit the screen (if the input is wide signal)

1:1 – the signal will be displayed on the center of the screen with 1:1 ratio. This means you may see the

signal at the center of the screen while it is surrounded by black area.

G. Setup Menu controls are explained below: Language allows you to choose the language used in the menus and control screens. Resolution Notice displays the recommended resolution for this LCD display. Enable allows the Resolution Notice to appear on-screen. Disable will not allow the Resolution Notice to appear on-screen. 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 OSD disappears.

OSD Position allows you to move the on-screen display menus and control screens.

H. 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.
