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
1024 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 optimal picture quality, please use the recommended timing mode specific to
your LCD display listed on the "Specification" page.
To set the Timing Mode:
• Setting the resolution: Access "Appearance and Personalization" from Control
Panel via the Start Menu, and set the resolution.
• Setting the refresh rate: See your graphic card's user guide for instructions.
IMPORTANT: Please make sure that your graphics card is set to 60Hz vertical
refresh rate as the recommended setting for most LCD displays. Choosing a non-
supported timing mode setting may result in no image being displayed, and a
message showing "Out of Range" will appear on screen.
