How to install Dell WD22TB4

Setting up the WD22TB4 is straightforward and designed to minimize desk clutter while maximizing flexibility. Start by placing the dock within easy reach of your workspace and connect it to your host computer using the included Thunderbolt 4 cable. The following steps guide you through a typical installation for a productive, multi‑display workstation:

Step 1: Connect the host to the dock. Insert the Thunderbolt 4 cable into the TB4/USB-C upstream port on the WD22TB4 and the corresponding Thunderbolt 4 port on your laptop or desktop. Ensure both devices are powered on and that the host OS recognizes the dock as a connected device. Step 2: Attach displays. Connect your monitors to the dock’s video outputs (HDMI and/or DisplayPort, depending on your monitor configuration and the dock’s current firmware). Step 3: Add peripherals. Plug in keyboards, mice, external storage, and other USB devices into the USB-A or USB-C ports. Step 4: Network and audio. Connect an Ethernet cable if you require wired networking for speed and reliability, and connect audio peripherals to the dock’s audio jack if applicable. Step 5: Power and test. Connect the dock to its power source if your setup requires it and verify that the host laptop charges via ExpressCharge and that all displays and peripherals are functioning as expected. Optional firmware updates can be performed through Dell’s software credentials, ensuring compatibility with the latest features and security enhancements. Step 6: Optimize for charging efficiency. If you’re using a Dell laptop with ExpressCharge, ensure power settings are configured to enable premium charging modes for the fastest possible battery replenishment during work sessions. Step 7: Manage cables. Use the dock’s design to route cables cleanly, reducing clutter and improving air flow and safety in busy work environments.
