3. Front Panel Function Control Description


Do the following to adjust the display setting: 1. To display the Main Menu, press button [1].

NOTE: All OSD menus and adjustment screens disappear automatically after about 15 seconds. This is adjustable through the OSD timeout setting in the setup menu.

2. To select a control to adjust, press or to scroll up or down in the Main Menu. 3. After the desired control is selected, press button [2]. A control screen like the one shown below appears.

The line at the bottom of the screen shows the current functions of buttons 1 and 2: Exit or select the Brightness control.

4. To adjust the control, press the up or down T buttons. 5. To save the adjustments and exit the menu, press button [1] twice. The following tips may help you optimize your display: Adjust the computer's graphics card so that it outputs a 1024 x 768 @ 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.)



Audio AdjustFor VA503m only Volume increases the volume, decreases the volume, and mutes the audio. Mute temporarily silences audio output.



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.

Main Menu ControlsAdjust the menu items shown below by using the up S and down T 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 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.



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, pressSandT.Important: If you select RECALL from the Main Menu when the product is set to a Preset Timing Mode, colors return to the 6500K factory preset.

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 1024 x 768 @ 60Hz (recommended) means that the resolution is 1024 x 768 and the refresh rate is 60 Hertz.

Manual Image Adjust displays the Manual Image Adjust menu.

H. Size (Horizontal Size) adjusts the width of the screen image.

H./V. Position (Horizontal/Vertical Position) moves the screen image left or right and up or down.



Control Explanation

Fine Tune sharpens the focus by aligning text and/or graphics with pixel boundaries.NOTE: Try Auto Image Adjust first.

Sharpness adjusts the clarity and focus of the screen image.

P.S: The 1N4148 Vf=0.7V~1V can't meetLDO spec. The BAT42, Vf is OK but theIf=200mA(forward current) can notmeet current spec.

D704(SSM12L) Vf=0.38V and If=1A.So when system power on, thesystem loading is about 400mA(3.3V is about 200mA and 1.8V isabout 200mA), So D35 changedfrom 1N4148(or BAT42) toSSM12L(schottky diode).
