Using the Monitor
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 monitor timing mode to one of the
following:
VESA 1280 x 1024 @ 85 Hz.
VESA 1600 x 1200 @ 75 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.
NOTE:
To minimize the adjustments required for an optimal screen image,
select a timing mode from the resolutions listed in the Specifications on page 11.
WARNING:
Do NOT set the graphics card in your computer to exceed the
maximum refresh rate; doing so may result in permanent damage to your
monitor.
