Targus DOCK190USZ vs DOCK310USZ - DisplayLink Dock Comparison 2026

Targus DOCK190USZ vs DOCK310USZ: the quick answer

The Targus DOCK190USZ and Targus DOCK310USZ are close enough that people naturally compare them. Both are USB-C DisplayLink docks. Both target office desks rather than gaming rigs. Both can run two 4K monitors at 60Hz without relying on the laptop’s native Thunderbolt or DisplayPort Alt Mode display limits.

The difference is how much desk the dock is supposed to handle. The DOCK190USZ is the stronger model on specs. It scores 7.4 in our product data, delivers up to 100W to the host laptop, includes two HDMI 2.0 ports, two DisplayPort 1.2a ports, four USB-A ports, one downstream USB-C data port, Gigabit Ethernet, audio, a detachable 1-meter host cable, and legacy laptop power tips. It is the more flexible pick for mixed monitor desks and higher-power laptops.

The DOCK310USZ is the simpler model. It scores 7.2, lists a $199.99 MSRP, delivers up to 65W to the host laptop, and sticks to two HDMI 2.0 outputs for dual 4K. It also has one downstream USB-C data port, three USB-A ports, Gigabit Ethernet, audio, a detachable 1-meter host cable with a tethered USB-A adapter, and a 5-year limited warranty. If your desk is just two HDMI monitors, keyboard, mouse, webcam, Ethernet, and a lower-power laptop, it makes plenty of sense.

The short verdict: the DOCK190USZ wins for most buyers choosing between these two because it has the higher score, stronger 100W charging, and more flexible video outputs. The DOCK310USZ is the better value-minded pick when 65W charging is enough, your monitors are HDMI, and the 5-year warranty matters more than DisplayPort and extra charging headroom.

Quick specs comparison

Display support: same dual 4K goal, different cabling

On paper, display support looks almost tied. The DOCK190USZ supports one 4K display at 60Hz or two 4K displays at 60Hz. The YAML says it can use the two DisplayPort 1.2a ports, the two HDMI 2.0 ports, or a mixed HDMI plus DisplayPort setup. That matters if your desk already has one HDMI monitor and one DisplayPort monitor, or if your office rotates different monitor models through the same dock.

The DOCK310USZ also supports dual 3840x2160 at 60Hz, but it does it through two HDMI 2.0 ports. It also lists single 5K@60Hz support through the DisplayLink video pipeline. For a home office with two HDMI monitors, that is all you need. For a desk with DisplayPort monitors, the DOCK310USZ forces adapters or new cables.

Both docks use DisplayLink for external displays. That is the whole reason they can be useful with base Apple Silicon MacBooks, older USB-C laptops, and systems whose native display output is limited. DisplayLink sends display data over USB and renders through software, so it does not care as much about the laptop’s built-in monitor count.

That flexibility comes with the usual DisplayLink tax. Windows and macOS users need DisplayLink software. macOS users also need to grant Screen Recording permission to DisplayLink Manager. Neither product is the right choice for high-refresh gaming, low-latency monitor use, or color-critical video editing. The product YAML for both docks calls out compression, latency, and driver friction as real drawbacks.

Display winner: DOCK190USZ. The actual monitor count is tied, but the DOCK190USZ gives you HDMI, DisplayPort, or mixed output. The DOCK310USZ is just as useful if both monitors are HDMI.

Charging: 100W is the practical dividing line

Charging is the cleanest reason to buy the DOCK190USZ. It delivers up to 100W USB-C Power Delivery to the host laptop. The YAML positions that as enough for most business ultrabooks and many 15-inch productivity laptops. It also flags a sensible limit: large mobile workstations and gaming laptops can still exceed 100W under load, so those machines may need their original charger.

The DOCK310USZ tops out at 65W. That is fine for many office notebooks, smaller ultrabooks, and MacBook Air style setups. It is less comfortable for 15-inch and 16-inch laptops, especially when the laptop is driving displays, running calls, syncing files, and charging from a lower battery level. The DOCK310USZ product data explicitly lists high-power laptops and mobile workstations as a mismatch because 65W may be too low.

This is where the spec sheet turns into a real buying decision. If the laptop came with a 45W or 65W charger, the DOCK310USZ can be enough. If it came with a 96W or 100W USB-C charger, the DOCK190USZ is the safer pick. If it came with something larger, neither Targus dock should be treated as a workstation power supply.

Both docks use external DC-barrel power. Neither is a tiny bus-powered travel hub. That is normal for DisplayLink docks that combine display output, Ethernet, USB, and host charging in one desktop unit.

Power winner: DOCK190USZ. 100W gives it far more headroom than the DOCK310USZ’s 65W limit.

Ports and desk layout

The DOCK190USZ has the more adaptable port layout. On video, it gives you two HDMI 2.0 ports and two DisplayPort 1.2a ports. On USB, it has one USB-C 3.1 data port, one USB-A 3.1 port with 7.5W charging, and three more USB-A 3.1 ports. It also includes Gigabit Ethernet and a 3.5mm combo audio jack. That covers a normal desk without much drama: two monitors, wired network, keyboard, mouse, webcam, USB headset or audio device, and a few peripherals.

The DOCK310USZ is more compact. It has two HDMI 2.0 ports, one USB-C 3.2 data port, three USB-A 3.2 ports, Gigabit Ethernet, and a 3.5mm combo audio jack. It is enough for basic office work, but it has one fewer USB-A port and no DisplayPort outputs. The YAML also notes that it has no SD card reader and no 2.5GbE, but the same is effectively true for the DOCK190USZ on those two points. Both are office docks, not creator docks.

The host cable detail is also worth separating. Both include detachable 1-meter USB-C host cables. The DOCK310USZ adds a tethered USB-A adapter, which is useful if you are connecting an older USB-A host for DisplayLink video and data. That adapter will not deliver USB-C Power Delivery to a laptop over USB-A, but it does make the DOCK310USZ friendlier for legacy hot desks.

The DOCK190USZ has its own mixed-fleet perk: legacy laptop power tips. The YAML calls this unusual on modern USB-C docks and useful for environments where older barrel-charging laptops are still around. That does not matter for a normal USB-C laptop, but IT teams with mixed hardware may care.

Port winner: DOCK190USZ. It has the same HDMI count, adds DisplayPort, includes one more USB-A port, and has more charging flexibility for the host.

Compatibility and setup

Compatibility is broadly similar because both docks solve the same problem with the same technology class. The DOCK190USZ lists Windows, macOS, ChromeOS, Linux, and Android support. The DOCK310USZ lists Windows, macOS, ChromeOS, Ubuntu Linux, and Android support. Both can work with Apple Silicon MacBooks through DisplayLink Manager, including base M-series MacBooks that normally support only one external monitor.

The setup story is also similar. Install DisplayLink first if you care about the monitors. On macOS, grant Screen Recording permission. Use the included USB-C cable or a USB 3.x-rated cable. Avoid USB 2.0-only cables or ports. If a corporate laptop blocks DisplayLink drivers, do not buy either dock for display output.

The DOCK310USZ is slightly easier for older USB-A hosts because of the tethered USB-A adapter. The DOCK190USZ is better for mixed USB-C and Thunderbolt 3 hosts that also need stronger charging. Targus describes the DOCK190USZ as Thunderbolt 3 compatible, but the YAML is clear that it is not a native Thunderbolt dock. Video still runs through DisplayLink, not through native Thunderbolt display lanes.

For a driverless desk, neither wins. If you want native display bandwidth, low latency, downstream Thunderbolt ports, or faster external SSD performance, look at a USB4 or Thunderbolt dock instead. Our docking station buying guide covers how to choose between those connection types.

Compatibility winner: tie overall. The DOCK310USZ has a legacy USB-A adapter advantage. The DOCK190USZ has stronger charging and broader monitor cabling.

Warranty and value

The DOCK310USZ has the clearer value argument from the YAML because it lists a $199.99 MSRP and a 5-year limited warranty. That is a strong combination for a dual 4K DisplayLink dock. If your setup is two HDMI monitors and a laptop that charges comfortably at 65W, it is hard to argue against the simpler model.

The DOCK190USZ does not list an MSRP in the product YAML, so I am not going to invent a price comparison. What the YAML does show is a higher score, 7.4 vs 7.2, stronger charging, more video output options, one more USB-A port, legacy power tips, and a 3-year limited warranty. That is the stronger feature set, but not the longer coverage.

This creates a real split. The DOCK310USZ is easier to standardize for lower-power hot desks because the warranty is longer and the layout is simple. The DOCK190USZ is easier to recommend when the desk has unknown monitor cabling, a bigger laptop, or users who need closer to 100W charging.

Do not ignore the DisplayLink part when thinking about value. If your laptop and monitors can run natively over USB-C Alt Mode, USB4, or Thunderbolt, a driverless dock may be a better long-term purchase. DisplayLink is valuable when it solves a specific problem: dual monitors on laptops that otherwise cannot do it, broad OS support, or old and new laptops sharing the same desk.

Value winner: depends on the laptop. DOCK310USZ has the warranty and listed MSRP advantage. DOCK190USZ has the stronger capability per dock.

Which one is better for MacBooks?

Both docks can be useful with MacBooks, especially base Apple Silicon models. A base M1, M2, M3, or M4 MacBook normally has a strict external display limit. DisplayLink can work around that for office tasks by rendering additional displays through software. That is why these docks appear in dual-monitor discussions even though they are not native Thunderbolt display docks.

For a MacBook Air or smaller MacBook Pro that only needs two HDMI monitors, the DOCK310USZ is enough. It gives you dual 4K HDMI, Ethernet, audio, USB-A ports, one USB-C data port, and 65W charging. You still need DisplayLink Manager and macOS permissions, but once configured, it fits a normal office desk.

For a 14-inch or 16-inch MacBook Pro, the DOCK190USZ is the safer Targus choice. Its 100W charging limit is closer to what larger MacBook Pro models expect, and its DisplayPort outputs help if your monitors are not HDMI. It still is not a native creative workflow dock. If the monitor is for color grading, video editing, high refresh rates, or latency-sensitive work, connect it directly or choose a native Thunderbolt dock.

The Mac answer is not about brand loyalty. It is about power and monitor cabling. Smaller MacBook, HDMI monitors, office work: DOCK310USZ. Bigger MacBook, mixed monitor inputs, more charging headroom: DOCK190USZ.

Which one is better for offices and IT teams?

For IT teams, the DOCK190USZ looks stronger for mixed desks. It supports USB-C and Thunderbolt 3 hosts, provides 100W charging, offers both HDMI and DisplayPort outputs, includes legacy laptop power tips, and has Targus utility positioning in the product data. The 3-year limited warranty is normal for business hardware, and the port layout is flexible enough for offices that do not want to standardize every monitor cable.

The DOCK310USZ is better for narrower deployments. If the office buys dual HDMI monitors, issues laptops that need 65W or less, and wants a compact dock with a 5-year limited warranty, it is a practical standard. The tethered USB-A adapter also helps if older hosts still appear at shared desks.

The biggest deployment question is driver policy. DisplayLink drivers need to be installed and maintained. On macOS, users or IT must approve Screen Recording permission. On locked-down Windows images, the DisplayLink driver needs to be part of the build or approved through the normal software process. If that sounds annoying, it is. It is also the trade-off that makes dual displays possible across so many host systems.

For general mixed-fleet offices, I would standardize on the DOCK190USZ first if the budget allows and the extra charging matters. I would use the DOCK310USZ for defined HDMI-only desks where users bring lower-power laptops.

Verdict: DOCK190USZ wins on capability

The Targus DOCK190USZ is the better dock in this comparison. It has the higher review score, 7.4 vs 7.2, stronger 100W USB-C Power Delivery, dual HDMI 2.0, dual DisplayPort 1.2a, more USB-A connectivity, and useful mixed-fleet extras such as legacy laptop power tips. It is the model I would pick for a larger laptop, an office desk with unknown monitor cables, or a setup where 65W charging might become a problem.

The Targus DOCK310USZ is not a bad choice. It is the cleaner pick for two HDMI monitors, lower-power laptops, and buyers who want the listed $199.99 MSRP and 5-year limited warranty. It also has the handy tethered USB-A adapter for legacy hosts. If those details match your desk, it can be the smarter purchase even though it loses the spec comparison.
