1.4 Initial Power-On

After all connections are secure, power on your computer, then press the power button on the monitor. The monitor should automatically detect the input signal. If not, you may need to manually select the input source using the OSD menu.

2. Operating the Monitor

2.1 On-Screen Display (OSD) Menu

The monitor's settings are controlled via an On-Screen Display (OSD) menu, typically accessed and navigated using a joystick or buttons located on the back or bottom right side of the monitor. Press the main OSD button to open the menu, then use the directional controls to navigate and select options.

2.2 Input Selection

To switch between connected devices (e.g., computer via HDMI, game console via DisplayPort), access the OSD menu and navigate to the 'Input' or 'Source' section. Select the desired input.

2.3 Picture-in-Picture (PIP) and Picture-by-Picture (PBP)

The AOC U4308V supports advanced multitasking features:

• Picture-in-Picture (PIP): Displays a secondary input source in a smaller window overlaid on the main display.
• Picture-by-Picture (PBP): Divides the screen into multiple sections, each displaying a different input source simultaneously. This is ideal for viewing content from several devices at once.

These modes can be configured through the OSD menu, allowing you to select the main and sub-sources, as well as the size and position of the PIP window or the layout of PBP screens.

2.4 Display Settings

Adjust various display parameters to optimize your viewing experience:

• Brightness/Contrast: Adjust the overall luminance and difference between light and dark areas.
• Color Settings: Fine-tune color temperature, gamma, and color space (e.g., sRGB, NTSC) to achieve accurate color reproduction. The IPS panel supports over 1 billion colors, offering 109% NTSC and 124% sRGB coverage.
• Flicker-Free Technology: This feature reduces screen flickering, minimizing eye strain during prolonged use.
• Low Blue Mode: Reduces harmful blue light emissions to protect your eyes and enhance viewing comfort, especially in low-light conditions.

2.5 USB 3.0 Hub

The integrated USB 3.0 hub provides four USB 3.0 ports, including one charging port. Connect your peripherals such as keyboards, mice, or external storage devices directly to the monitor for convenience. Ensure the USB upstream cable is connected to your computer for the hub to function.

3. Maintenance

3.1 Cleaning the Monitor

To maintain optimal performance and appearance, clean your monitor regularly:

• Screen: Gently wipe the screen with a soft, lint-free cloth. For stubborn marks, use a monitor-specific cleaning solution applied to the cloth (never directly to the screen).
• Casing: Use a soft, dry cloth to clean the monitor casing. Avoid using abrasive cleaners or solvents.

3.2 Environmental Considerations

Ensure the monitor is placed in a well-ventilated area, away from direct sunlight, heat sources, and excessive dust. Operating the monitor within its recommended temperature and humidity ranges will prolong its lifespan.

3.3 Power Management

To conserve energy, enable power-saving features in your computer's operating system or the monitor's OSD menu. Power off the monitor when not in use for extended periods.

4. Troubleshooting

If you encounter issues with your AOC U4308V monitor, refer to the following common problems and solutions:

4.1 No Display / Black Screen

• Check if the monitor is powered on and the power indicator light is active.
• Verify that the video cable (HDMI, DP, VGA) is securely connected to both the monitor and the computer.
• Ensure the correct input source is selected on the monitor via the OSD menu.
• Test the monitor with another video source or cable if possible.

4.2 Image Quality Issues

• Blurry/Distorted Image: Adjust the display resolution on your computer to the monitor's native resolution (3840x2160).
• Incorrect Colors: Reset color settings to factory defaults in the OSD menu or adjust them manually. Ensure your graphics card drivers are up to date.
• Dead Pixels: While rare, a few dead or stuck pixels are within industry standards. If the number exceeds manufacturer specifications, contact support.

4.3 No Sound from Speakers

• Check the volume settings on both the monitor (OSD menu) and your computer.
• Ensure the audio cable is correctly connected, or if using HDMI/DP, verify that your computer's audio output is set to the monitor.

4.4 USB Hub Not Functioning

• Confirm that the USB upstream cable is connected from the monitor to your computer.
• Check your computer's device manager for any USB driver issues.
