What is the maximum display resolution and configuration this dock supports?
▼
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.
Will this dock work with non-HP laptops that have Thunderbolt 3?
▼
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.
Can this dock drive two 4K monitors simultaneously, and what connection options does it support?
▼
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.
Does the dock deliver the full 90W of power delivery to connected laptops?
▼
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.
What is the data transfer speed on the USB 3.0 ports on this dock?
▼
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.
What is the actual USB bandwidth on the four USB 3.0 ports?
▼
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.
Does the 90W power delivery fully charge all compatible HP EliteBook models under load?
▼
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.
Does the Thunderbolt 3 port on the dock support USB 3.1 Gen 2?
▼
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.
Is this dock compatible with non-HP Thunderbolt 3 laptops?
▼
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.
Is the VGA output suitable for driving an older 1080p conference room display?
▼
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.
