Overview

The HP 1DT93UT Elite Thunderbolt 3 Dock is a single-cable docking solution that transforms a compatible HP laptop into a full desktop workstation via a 40 Gbps Thunderbolt 3 connection. The 90W power delivery over that same cable means your EliteBook charges at full speed while simultaneously driving two UHD/4K displays through the dual DisplayPort outputs, offloading data through four USB 3.0 ports at 5 Gbps each, and maintaining a wired Gigabit Ethernet connection. The inclusion of both VGA and DisplayPort outputs reflects the enterprise market reality: conference rooms still run legacy projectors, and this dock bridges that gap without an adapter bag.

This dock is built for the enterprise mobile worker — the EliteBook user who moves between a home office, a corporate desk, and a meeting room and needs a single-cable transition between each. The connectivity breadth (10 ports) handles the full peripheral stack of a knowledge worker: dual external monitors, wired network, USB peripherals, and audio — all while keeping the laptop topped up. The HP-exclusive optimization is both a strength and a hard boundary: if your fleet is standardized on HP hardware, this dock delivers a polished, validated experience. If you're running a mixed-vendor environment or a newer platform, verify compatibility before purchasing, as full feature activation depends on HP's firmware handshake.

Key Features

Link up to 10 devices at once through ports that include Thunderbolt 3 (which also supports Display Port 1.2 and USB 3.1 Gen 2), four USB 3.0, RJ-45, VGA, Combo Audio, and two additional DisplayPort ports.

Pros & Cons

👍 Pros

  • 90W power delivery via a single Thunderbolt 3 cable eliminates the laptop power brick entirely for compatible HP EliteBook models — a genuine cable reduction for desk-based workflows
  • Thunderbolt 3 interface delivers 40 Gbps bidirectional bandwidth — sufficient for dual 4K displays plus full USB 3.1 Gen 2 peripheral throughput simultaneously
  • 90W power delivery via the single Thunderbolt 3 cable eliminates the laptop's separate power brick while docked, reducing desk cable clutter to one connection
  • Thunderbolt 3 with DisplayPort 1.2 and USB 3.1 Gen 2 support on the primary port provides up to 40Gbps aggregate bandwidth, supporting simultaneous dual 4K display, high-speed storage, and data transfer without saturation
  • Dual DisplayPort outputs plus the Thunderbolt 3 port's DP capability enables a three-display configuration for compatible hosts — meaningful for multi-monitor productivity workflows
  • Ten-device connectivity in a single dock — four USB 3.0, two DisplayPort, VGA, RJ-45, combo audio, and Thunderbolt 3 — covers virtually every peripheral category
  • Dual UHD/4K display support enables a true productivity multi-monitor setup without requiring a dedicated external GPU
  • Four USB 3.0 Type-A ports at 5Gbps each sustain full-speed connections to external drives, peripherals, and hubs simultaneously without the port-sharing limitation of 2-port docks
  • RJ-45 Ethernet provides wired LAN connectivity that bypasses Wi-Fi latency and stability variance — essential for VPN, VoIP, and latency-sensitive enterprise applications
  • RJ-45 Gigabit Ethernet provides reliable wired network throughput that Wi-Fi cannot match for large file transfers or VPN-intensive enterprise workflows

👎 Cons

  • Full 90W power delivery and feature validation is limited to specific HP EliteBook and Elite X2 models — non-HP and non-listed HP machines may receive reduced charging or untested behavior
  • HP-exclusive compatibility validation means full 90W charging and firmware-level features are locked to specific HP EliteBook and ProBook models — not a universal Thunderbolt dock
  • No USB-C passthrough port beyond the Thunderbolt 3 host connection limits expandability for newer peripherals that require USB-C
  • No USB-C passthrough port separate from the Thunderbolt 3 input — devices requiring USB-C data connections must use the TB3 port, competing with the laptop's primary connection
  • VGA port outputs a legacy analog signal at maximum 1920x1200, which is a mismatch with the dock's otherwise 4K-capable digital port set — relevant only to users with older VGA displays
  • VGA output caps at analog resolution, making it the weakest link for users needing a third display at 4K quality
  • The dock requires its own 90W AC adapter, adding a second power brick to the desk setup rather than drawing all power from a laptop charger
  • The 90W AC adapter is a separate, bundled brick that adds desk clutter — the single-cable benefit to the laptop is partially offset by the dock's own power supply footprint
  • HP ecosystem lock-in is real: users who change to non-HP hardware cannot guarantee power delivery or full feature operation, shortening the dock's effective useful life relative to more universal alternatives
  • No built-in SD card reader, requiring an additional peripheral for photographers or field workers who use memory cards regularly

Frequently Asked Questions

The HP Elite 90W Thunderbolt 3 Dock supports dual UHD (3840x2160) 4K display output simultaneously via its two DisplayPort ports, with the Thunderbolt 3 port also supporting DisplayPort 1.2. The maximum configuration depends on the host laptop's GPU output capability — the dock passes display signals but relies on the host's display engine for resolution and refresh rate limits.
Officially, HP validates this dock against specific HP EliteBook, ProBook, and Elite x2 models. While the Thunderbolt 3 standard is universal, HP's firmware-level handshake for 90W power delivery and full feature activation is optimized for HP-certified hardware — expect reduced functionality or no power delivery on third-party systems.
Yes, it supports dual UHD/4K displays. You can use the two dedicated DisplayPort outputs, or mix DisplayPort with the Thunderbolt 3 port's native DisplayPort 1.2 signal — giving you flexible multi-monitor configurations without a discrete GPU requirement.
The 90W power delivery is transmitted via the Thunderbolt 3 cable to compatible HP EliteBook models. Actual charging rate depends on the laptop's power acceptance — some HP models may accept less than 90W. Non-HP laptops connected via Thunderbolt 3 may receive power delivery at a lower negotiated rate or not at all, as HP validates power delivery specifically on listed compatible models.
The four USB 3.0 Type-A ports operate at USB 3.0 Gen 1 speed — a theoretical maximum of 5Gbps per port. In practice, connected bus-powered storage and peripherals share available bandwidth on the USB 3.0 controller hub. Each port is independently capable of 5Gbps; simultaneous use across all four ports will be bandwidth-limited by the controller's total allocation.
Each USB 3.0 port supports up to 5 Gbps. They share bandwidth through the dock's internal hub, so saturating all four simultaneously will distribute that bandwidth — relevant if you're running multiple high-throughput storage devices concurrently.
90W is sufficient for most HP EliteBook and Elite x2 models under moderate workloads. Thin-and-light models with 45W TDP CPUs will charge simultaneously with usage. Higher-performance configurations running sustained loads may see slower net charging, but the laptop will not discharge while docked.
Yes. Thunderbolt 3 is electrically compatible with USB 3.1 Gen 2 (10Gbps), and HP confirms this dock's Thunderbolt 3 port supports USB 3.1 Gen 2. This allows USB 3.1 Gen 2 devices connected to the Thunderbolt port to operate at 10Gbps, doubling the throughput available on the dedicated USB 3.0 Type-A ports.
Partially. The Thunderbolt 3 electrical standard is universal, so display output and USB hub functionality will work on any TB3 host. However, the 90W power delivery and full feature validation are specific to HP-listed compatible models. Non-HP laptops may experience reduced power delivery or untested behavior on proprietary HP features.
Yes. The VGA output supports legacy displays up to 1920x1200 resolution, making it backward-compatible with older projectors and conference room monitors without an adapter.
