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.) ViewSonic Corporation 8 Confidential - Do Not Copy VG920-1 Main Menu Controls Adjust the menu items shown below by using the up and down buttons. Explanation Control Auto Image Adjust sizes and centers the screen image automatically. Contrast adjusts the difference between the image background (black level) and the foreground (white level). Brightness adjusts background black level of the screen image. Input Select allows the user to toggle between an analog and a digital signal. Audio Adjust 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). 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. 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 ▼ and ▲. 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. ViewSonic Corporation 9 Confidential - Do Not Copy VG920-1 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 card’s 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 Sub-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. 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. ViewSonic Corporation 10 Confidential - Do Not Copy VG920-1 Setup Menu displays the menu shown below: Language Select allows the user to choose the language used in the menus and control screens.
