Operating the Monitor
On-Screen Display (OSD) Menu
The OSD menu allows you to adjust various monitor settings. The control buttons are typically located on the bottom right or back of the monitor.
- Press any OSD button to activate the OSD menu.
- Use the navigation buttons (usually directional arrows) to move through menu options.
- Press the select button (often the middle button) to enter a sub-menu or confirm a selection.

Key Settings and Adjustments
- Brightness/Contrast: Adjust the overall luminance and difference between light and dark areas.
