Operating Instructions
1. Powering On/Off
Press the power button, typically located on the back or bottom right of the monitor, to turn the monitor on or off. An indicator light will show the power status.
2. On-Screen Display (OSD) Menu
The OSD menu allows you to adjust various display settings. Buttons for OSD navigation are usually located on the back of the monitor. Use these buttons to navigate through options such as brightness, contrast, color temperature, input source, and picture modes.
3. Display Modes (PIP/PBP)
The monitor supports Picture-in-Picture (PIP) and Picture-by-Picture (PBP) modes, allowing you to display content from two different sources simultaneously. Refer to the OSD menu for options to configure these modes.

4. Refresh Rate and FreeSync
To achieve the 165Hz refresh rate, ensure you are using a DisplayPort connection and that your graphics card supports this refresh rate. Enable FreeSync in your graphics card settings and through the monitor's OSD menu to synchronize the monitor's refresh rate with your GPU's frame rate, reducing screen tearing and stuttering.
