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

NOTE: Auto Image Adjust works with most common video cards. If this

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

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.

Troubleshooting
No power
• Make sure power button (or switch) is ON.
• Make sure A/C power cord is securely connected to the LCD display.
• Plug another electrical device (like a radio) into the power outlet to verify that the outlet is
supplying proper voltage.
Power is ON but no screen image
• Make sure the video cable supplied with the LCD display is tightly secured to the video
output port on the back of the computer. If the other end of the video cable is not attached
permanently to the LCD display, tightly secure it to the LCD display.
• Adjust brightness and contrast.
• If you are using an Macintosh older than G3, you need a Macintosh adapter.
Wrong or abnormal colors
• If any colors (red, green, or blue) are missing, check the video cable to make sure it is
securely connected. Loose or broken pins in the cable connector could cause an improper
connection.
• Connect the LCD display to another computer.
• If you have an older graphics card, contact ViewSonic
® for a non-DDC adapter.
Control buttons do not work
• Press only one button at a time.
