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 1280 x 1024) 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 1280 x 1024 @ 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
.

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.
