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 60 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 @ 60 Hz.
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.
