Viewsonic G220F ユーザーズマニュアル

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 1600 x 1200) 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 1600 x 1200 @ 75 Hz or 85 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.

Do not set the graphics card in your computer to exceed the 

maximum refresh rate; doing so may result in permanent damage to your CRT 
display.
