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: VESA 1280 x 1024 @ 75 Hz. To set the Resolution: 1 Right-click on the Windows desktop. 2 Click Properties on the drop-down menu. 3 Click the Settings tab. 4 Move the slider pointer which displays in the Desktop area or Screen area in the window. NOTE: The refresh rate should already be set if you have done the CD installation (or refer to your graphics card documentation).
