Targus DOCK315USZ Review 2026 - Specs, Pros & Cons

Name: Targus Universal USB-C DV4K DP Docking Station with 65W Power Delivery (DOCK315USZ)
Brand: Targus
SKU: DOCK315USZ

The Targus DOCK315USZ is a compact universal desk dock with two DisplayPort outputs, 65W USB-C Power Delivery, and a host cable that also adapts to USB-A laptops. Targus lists support for Windows, macOS, Ubuntu, Android, and ChromeOS, which makes it a practical fit for shared desks with mixed hardware. Its DisplayLink video path is the reason it can deliver dual 4K@60Hz without relying on a laptop's native multi-monitor support. It also means the dock needs software for external displays, so this is not a plug-and-play native video dock. The rear layout has two DisplayPort outputs, Gigabit Ethernet, three USB-A ports, and DC power. A USB-C data port, 3.5mm combo jack, and lock slot round out the hardware. Targus includes a 100W power supply and a 1-meter USB-C host cable with a tethered USB-A adapter, while the dock provides up to 65W to a USB-C laptop. That is enough for many office notebooks, but not every mobile workstation. For office monitors, browsers, calls, and spreadsheets, the DOCK315USZ offers more host flexibility than a typical native USB-C dock. Fast motion, gaming, and color-critical work are better handled through a native USB4 or Thunderbolt connection.

Best for mixed USB-C and USB-A workstations

Pros & Cons

What We Like

Dual 4K@60Hz output through two DisplayPort ports
DisplayLink enables external displays on both USB-C and USB-A hosts
65W USB-C Power Delivery suits many ultrabooks and office laptops
Five-year limited warranty is longer than most docking-station coverage
Includes a 1-meter USB-C host cable with a tethered USB-A adapter
Gigabit Ethernet, audio, three USB-A ports, and a USB-C data port cover a basic office desk

What Could Be Better

DisplayLink setup adds software and permissions work
Workaround: Install DisplayLink Manager or the Windows DisplayLink driver before connecting monitors. On corporate devices, confirm that IT allows the driver.
65W charging is not enough for every workstation or gaming laptop
Workaround: Use the laptop's own charger if the battery drains while docked, or select a dock with higher USB-C Power Delivery.
DisplayPort-only video outputs may require adapters for HDMI monitors
Workaround: Use DisplayPort monitors or active DisplayPort-to-HDMI adapters that support the required resolution and refresh rate.
DisplayLink video is not ideal for games, high-refresh displays, or color-critical editing
Workaround: Use the dock for productivity displays, or connect performance-sensitive monitors directly to the laptop.
No card reader or 2.5GbE port

Known Issues

Systems where DisplayLink software cannot be installed

External displays will not work

High-power laptops and mobile workstations

65W charging may be insufficient

Gaming, high-refresh, or color-critical display setups

DisplayLink adds compression and latency

USB 2.0-only host ports or cables

Insufficient bandwidth for the dock

7.3 /10

Our Verdict

Very Good

The DOCK315USZ is a sensible choice for a mixed-device office that already uses DisplayPort monitors. Its biggest strengths are broad host support, dual 4K@60Hz output, the included USB-A adapter, and Targus's five-year limited warranty. A base Apple Silicon MacBook can also use two external monitors through DisplayLink, provided DisplayLink Manager is installed and granted Screen Recording permission. The trade-offs are real. DisplayLink adds a software layer, so it can introduce latency and compression in high-motion workloads. Driver updates and sleep-wake troubleshooting are part of owning this kind of dock. Charging also tops out at 65W, which is fine for many ultrabooks but modest for a 15-inch or 16-inch performance laptop. The port selection is focused rather than generous: one downstream USB-C data port, three USB-A ports, Ethernet, audio, and no card reader. Buy it if you want a long-warranty DisplayPort desk dock for productivity across USB-C and older USB-A hosts. Choose a native USB4 or Thunderbolt dock if you need low-latency video, faster storage, high-refresh displays, or more charging headroom.

Frequently Asked Questions

Does the Targus DOCK315USZ require drivers?

Yes. The DOCK315USZ uses DisplayLink for external displays, so install DisplayLink software before relying on its DisplayPort outputs. USB peripherals, Ethernet, and charging may still work without the software, but the intended monitor setup will not.

Can the Targus DOCK315USZ run two 4K monitors?

Yes. Targus lists dual 4K UHD at 60Hz through the two DisplayPort outputs. The displays use the dock's DisplayLink video path, so software is required for the intended output.

How much power does the DOCK315USZ deliver to a laptop?

The dock delivers up to 65W of USB-C Power Delivery to a compatible laptop. That is enough for many office notebooks, but larger workstations and gaming laptops may need their original charger.

Does the DOCK315USZ work with Apple Silicon MacBooks?

Targus lists macOS support. With DisplayLink Manager installed and Screen Recording permission enabled, the dock can provide external-display support to Apple Silicon MacBooks. It is best suited to productivity work rather than high-motion video or games.

What is the difference between the DOCK315USZ and DOCK310USZ?

They share a compact DisplayLink design, 65W host charging, a 100W power adapter, three USB-A ports, one USB-C data port, Ethernet, audio, and a five-year limited warranty. The DOCK315USZ has two DisplayPort outputs, while the DOCK310USZ has two HDMI outputs.
