5. Adjustment Procedure
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 the best picture quality set your LCD display timing mode to:
VESA 1920 x 1080 @ 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.
