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 1024 x 768) and refresh rate (or vertical frequency;
example 75 Hz). After setting the timing mode, use the OnView® controls
to adjust the screen image.
For the best picture quality set your LCD display timing mode to:
VESA 1024 x 768 @ 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 card's 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.
OSD and Power Lock Settings
You can lock the On Screen Displays (OSDs) and/or the power button to prevent
unwanted changes to the current image settings.
• OSD LOCK: Press and hold the [1] and [▲] buttons on the face of the
monitor for 10 seconds. The message ODLOCKwill then display briefly
indicating that the OSD image settings are now locked.
• OSD UNLOCK: Press and hold the [1] and [▲] buttons again for 10
seconds. The message ODUNLOCKwill then display briefly indicating
that the OSD image settings are now unlocked.
• POWER BUTTON LOCK: Press and hold [1] and the down arrow ▼ for 10
seconds. If the power button is pressed the message owerButtonLocked
will display for 5 seconds. With or without this setting, after a power failure,
your LCD display’s power will automatically turn ON when power is
restored.
• POWER BUTTON UNLOCK: Press and hold [1] and the down arrow ▼

Troubleshooting
No power
• Make sure power button (or switch) is ON.
• Make sure A/C power cord is securely connected to the DC power supply and
the power supply is firmly 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.
