Using the ViewPanel

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 60

Hz). After setting the timing mode, use the OnView

controls to adjust the

screen image.

For the best picture quality set your ViewPanel:

VESA

1280 x 1024 @ 60 Hz

To set the Timing Mode:

Set the resolution: Right-click on the Windows

desktop > Properties >

Settings > set the resolution.

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 ViewPanel.
