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 1920 x 1080) 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 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 displays. Choosing a nonsupported timing mode setting may result in no image being displayed, and a message showing "Out of Range" will appear on screen.
