Setup Guide
Follow these steps to set up your Kensington SD4750P Docking Station:
- Power Connection: Connect the 135W power adapter to the "DC 20V" port on the rear of the docking station, then plug the adapter into a power outlet. The blue power indicator LED on the front of the dock should illuminate.
- Connect to Laptop: Use the included 1-meter USB-C cable to connect the "USB-C Host Port" on the rear of the docking station to a USB-C port on your laptop. If your laptop uses USB-A, an optional USB-A adapter may be required (not included with the standard package).
- Install DisplayLink Drivers: The Kensington SD4750P utilizes DisplayLink technology for video output. Before connecting external monitors, download and install the latest DisplayLink drivers for your operating system (Windows, macOS, ChromeOS) from the official DisplayLink website or Kensington's support page.
- Connect Monitors: Connect your external monitors to the docking station using either the DisplayPort 1.2++ or HDMI 2.0 ports. You can use two DisplayPort cables, two HDMI cables, or one of each. Ensure your monitors are powered on and set to the correct input source.
- Connect Peripherals: Connect your USB devices (keyboard, mouse, external drives, etc.) to the available USB-A or USB-C ports on the docking station. For wired network access, connect an Ethernet cable to the Gigabit Ethernet port.
- Audio Devices: Connect headphones or speakers to the 3.5mm headphone jack and a microphone to the 3.5mm microphone jack if desired.
For optimal performance and to manage display settings, consider installing the free Kensington DockWorks™ Software, available from the Kensington website.
Operating Instructions
Once the docking station is set up, operating it is straightforward:
- Power On/Off: Use the power button on the front of the docking station to turn it on or off. When the dock is powered on and connected to a laptop, the blue power indicator LED will be lit.
- Laptop Charging: If your laptop supports USB-C Power Delivery, it will begin charging automatically when connected to the dock's USB-C Host Port.
- Display Configuration: After connecting your monitors, your operating system should detect them. You can configure display settings (e.g., extend, duplicate, resolution) through your computer's display settings. For Windows, right-click on the desktop and select "Display settings." For macOS, go to System Settings > Displays.
- USB Device Usage: Connected USB devices will function as if directly connected to your laptop.
- Network Connectivity: The Gigabit Ethernet port provides a stable wired network connection, which is often more reliable than Wi-Fi.
Maintenance
To ensure the longevity and optimal performance of your docking station, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the docking station. Avoid using abrasive cleaners, solvents, or strong chemicals, as they may damage the surface.
- Ventilation: Ensure the docking station is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
- Cable Management: Keep cables organized and untangled to prevent damage to the ports or cables themselves. Avoid sharp bends or excessive pulling on cables.
- Storage: When not in use for extended periods, store the docking station in a cool, dry place away from direct sunlight and extreme temperatures.
