The Dell D3100 connects via a single USB 3.0 cable to deliver triple 4K-capable display outputs, six USB 3.0 ports, Gigabit Ethernet, and audio — no proprietary dock connector required, works with any USB 3.0 laptop. Power adapter included. Backed by a full 12-month warranty from Reboot IT (Melbourne, est. 2001).
The D3100 uses DisplayLink technology, which means it works across Windows and macOS with the appropriate driver installed. Setup takes a few minutes — install the DisplayLink driver, plug in the dock, and all three monitors and peripherals appear. No reboots required after initial setup.
For creative professionals, connecting a 4K display via DisplayPort delivers noticeably sharper images for photo editing and video review compared to 1080p. The remaining two HDMI outputs handle reference monitors or secondary work screens.
The universal USB 3.0 connection is its biggest advantage over proprietary docking solutions — it moves with you between laptops, works with Surface, MacBook (via USB-A adapter), ThinkPad, Dell XPS, and HP EliteBook alike without any compatibility concerns.

✗ Not Ideal For: • Users needing 4K on all three outputs (only DP is 4K) • Those who want plug-and-play without driver install • Laptops without USB 3.0 Type-A (USB-C only machines) • High-frame-rate gaming (DisplayLink adds latency) • Users needing Thunderbolt bandwidth |
| Grade | Cosmetic Condition | Functionality |
|---|---|---|
| A — Excellent | Minimal signs of use; housing near-new | All ports and functions fully tested and operational |
| B — Good | Light wear marks or minor scuffs | All ports and functions fully tested and operational |
Do I need to install a driver?
Yes — the D3100 uses DisplayLink technology and requires the free DisplayLink driver available from the DisplayLink website. Installation takes a few minutes and a reboot, after which all monitors and ports work automatically.
Does it work with a MacBook?
Yes — DisplayLink supports macOS. You'll need a USB-A to USB-A cable (or USB-C adapter for newer MacBooks) and the macOS DisplayLink driver. Video output works on Intel-based Macs; Apple Silicon Macs may have limitations with multiple monitors.
Can all three monitors run at 4K?
Only the DisplayPort output supports 4K UHD (3840×2160@30Hz). The two HDMI outputs support up to 1920×1080@60Hz. For a full 4K triple setup, consider a Thunderbolt dock instead.
Is the power adapter included?
Yes — a compatible power adapter is included with this listing. No additional purchase required.
