Using the 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 display listed on the “Specification” page.

To set the Timing Mode:

  • Setting the resolution: Access “Appearance and Personalization” from the Control Panel via the Start Menu, and set the resolution.
  • Setting the refresh rate: See your graphics card’s user guide for instructions.

OSD and Power Lock Settings
