4. Setup Instructions
Follow these steps to properly set up your VEDINDUST HDMI Splitter Extend:
Figure 4.1: Installation Driver Steps. This visual guide outlines the four essential steps for setting up the HDMI splitter, emphasizing the critical driver installation process for both Windows and macOS systems.
- Connect USB Cable: Connect the provided USB-A 3.0 cable from the splitter's USB port to an available USB port on your computer. This connection is crucial for both power and driver functionality.
- Driver Installation:
- For Windows Systems: After connecting the USB cable, your computer should automatically recognize the device and prompt for driver installation. If not, manually locate and run the driver file from the virtual disk that appears.
- For macOS Systems: After connecting the USB cable, install and open the 'USB Display.app'. This application must remain running in the background for the splitter to function correctly.
Important: The USB connection and driver installation are mandatory for the device to operate and achieve the specified resolutions.
- Connect HDMI Cables: Connect an HDMI cable from your computer's HDMI output to the HDMI IN port on the splitter. Then, connect HDMI cables from the splitter's OUT1 and OUT2 ports to your respective monitors, TVs, or projectors.
- Power On: Ensure all devices (computer and displays) are powered on.
5. Operating Instructions
Once the splitter is set up, you can configure your display settings on your computer for either screen extension or duplication.
5.1 Display Modes
Figure 5.1: Supported Display Modes. This image demonstrates the three primary display configurations: extending the desktop across three screens (A-B-C), extending with one duplicated screen (A-B-B), and mirroring the primary display across all screens (A-A-A), all supported on Windows and macOS.
- Screen Duplication (Mirror Mode): Both connected monitors will display the exact same content as your computer's primary screen. This is useful for presentations or sharing content.
- Screen Extension (Extend Mode): Your computer's desktop will be extended across the two connected monitors, allowing you to have different content on each screen. This is ideal for multitasking and increasing your workspace.
5.2 Configuring Display Settings
To switch between duplication and extension modes, you must adjust the display settings within your computer's operating system:
- For Windows: Right-click on your desktop, select 'Display settings', and then choose 'Extend these displays' or 'Duplicate these displays' as needed. You can also rearrange the displays.
- For macOS: Go to 'System Settings' (or 'System Preferences'), then 'Displays'. Here you can arrange your displays and select 'Mirror Displays' or use them as separate extended desktops.
5.3 Resolution Output
Figure 5.2: HDMI Dual Display Adapter Output. This image illustrates the maximum resolution capabilities of each output port: OUT1 supports up to 4K@60Hz, while OUT2 supports up to 1080P@60Hz, allowing for a dual-monitor setup with varying display qualities.
- OUT1: Supports a maximum resolution of 4K@60Hz. To achieve 4K@60Hz output, ensure both the HDMI cable and the USB cable are connected to a compatible USB 3.0 port on your computer.
- OUT2: Supports a maximum resolution of 1080P@60Hz.
The output resolution is also dependent on the USB version connected to your computer. When connected to a computer's USB 3.0 port, the maximum resolution for OUT1 is 4K@60Hz and for OUT2 is 1080P@60Hz. When connected to a USB 2.0 port, the maximum resolution for both outputs will be limited to 720P.
6. Troubleshooting
If you encounter issues with your VEDINDUST HDMI Splitter Extend, please refer to the following common solutions:
- No Display/Black Screen:
- Ensure all HDMI and USB cables are securely connected.
- Verify that the USB cable is connected to your computer and the necessary drivers are installed and running (especially for macOS, ensure 'USB Display.app' is active).
- Check your computer's display settings to ensure the external monitors are detected and configured for either extend or duplicate mode.
- Test with different HDMI cables or monitors to rule out faulty peripherals.
- Incorrect Resolution/Lower Resolution Than Expected:
- Confirm that the USB cable is connected to a USB 3.0 port on your computer for optimal resolution (1080P for USB 3.0, 720P for USB 2.0).
- Ensure the driver is correctly installed and updated.
- Verify that your monitors support the desired resolution.
- Remember that OUT1 supports up to 4K@60Hz, while OUT2 supports up to 1080P@60Hz.
- Flickering Screen or Unstable Connection:
- Ensure the USB cable provides sufficient power. Try connecting to a different USB port or using a powered USB hub if available.
- Check for any interference from other electronic devices.
- Update your computer's graphics drivers.
- Driver Installation Issues:
- For Windows, try running the driver installation file as an administrator.
- For macOS, ensure you have granted necessary permissions for the 'USB Display.app' to run.
- Temporarily disable antivirus software during installation if it interferes.
