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 1280 x 1024) and refresh rate (or vertical frequency;
example 75 Hz). After setting the timing mode, use the OnView®controls
to adjust the screen image.
The recommended timing modes for this monitor are:
VESA 1024 x 768 @ 75 Hz and VESA 1600 x 1200 @ 75 Hz.
To set the Timing Mode:
1Set the resolution: Right-click on the Windows®desktop > Properties >
Settings > Desktop or Screen Area > set the resolution.
2Set 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 Preset Timing Modes table below.
WARNING: Do NOT set the graphics card in your computer to exceed the
maximum refresh rate for each resolution (see below). Doing so may result in
permanent damage to your monitor.
