Using the LCD Display
Setting the Timing Mode
Setting the timing mode is important for maximizing the quality of the screen image and
minimizing eye strain. The timing mode consists of the resolution (example 1920 x 1080) and
refresh rate (or vertical frequency; example 60 Hz). After setting the timing mode, use the
OSD (On-screen Display) controls to adjust the screen image.
For the best picture quality set your LCD display timing mode to:
VESA 1920 x 1080 @ 60Hz.
To set the Timing Mode:
1. Set the resolution: Right-click on the Windows desktop > Properties > Settings > set the 
resolution.
2. Set the refresh rate: See your graphic cards user guide for instructions.
WARNING: Do not set the graphics card in your computer to exceed the maximum refresh
rate of 75Hz; doing so may result in permanent damage to your LCD display
.

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

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.
Input Select toggles between inputs if you have more than one computer 
connected to the LCD Display.

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

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.
