Using the LCD Display

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 1366 x 768) and

refresh rate

 (or vertical frequency; example 60 Hz). After setting the timing mode, use the

OSD (On-screen Display) controls to adjust the screen image.

For the best picture quality set your LCD display timing mode to:

VESA 1366 x 768 @ 60Hz.

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.

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 LCD display.
