Belkin Thunderbolt 3 Dock Pro vs Connect Pro TB4 Comparison 2026

Belkin Thunderbolt 3 Dock Pro vs Belkin Connect Pro TB4: the short version

Belkin’s older Thunderbolt 3 Dock Pro and newer Connect Pro Thunderbolt 4 Dock look like a simple generation upgrade at first. One is a late Thunderbolt 3 workstation dock from the F4U097 era. The other is a Thunderbolt 4 certified 12-in-1 dock with dual HDMI, USB4 compliance, and slightly higher host charging.

The decision is not that clean.

The newer Connect Pro TB4 wins on paper if you run Windows and want two HDMI monitors without adapters. It supports dual 4K@60Hz through its two HDMI 2.0 ports on Windows, lists a single 8K@30Hz mode through downstream Thunderbolt 4, and can charge the host laptop at up to 90W. It also has Thunderbolt 4 certification, which brings USB4 compliance and a clearer compatibility story for modern Windows laptops.

The older Thunderbolt 3 Dock Pro wins this comparison overall in our data. Its score is 7.0 versus 6.5 for the Connect Pro TB4. It has five USB-A ports instead of four, a faster UHS-II SD reader instead of UHS-I, native dual 4K@60Hz through DisplayPort plus downstream Thunderbolt, and fewer severe Mac-specific display caveats. It is not the dock to buy at full original MSRP in 2026, but if you are choosing specifically between these two Belkin docks, the F4U097 is the more balanced pick unless you know you need the Connect Pro’s dual HDMI layout.

Quick specs comparison

Why the Thunderbolt 3 Dock Pro wins overall

The Thunderbolt 3 Dock Pro wins because it is the more practical mixed-platform dock in the YAML data. Its headline specs are older, but the actual desk experience is less compromised.

The F4U097 gives you five USB-A ports, one USB-C 3.1 Gen 2 port, Gigabit Ethernet, one DisplayPort output, one downstream Thunderbolt 3 port, a UHS-II SD reader, and a 3.5mm combo audio jack. That is a very usable permanent-desk layout for keyboards, mice, webcams, older USB drives, card readers, and a pair of monitors.

The Connect Pro TB4 is newer, but its advantages are narrower. It has two HDMI 2.0 outputs, one downstream Thunderbolt 4 port, one USB-C 3.1 Gen 2 port with 20W accessory charging, two USB-A 3.1 ports, two USB-A 2.0 ports, Gigabit Ethernet, UHS-I SD, and a 3.5mm combo jack. The dual HDMI ports are convenient on Windows, but the YAML is clear that macOS does not support MST, so those two HDMI ports only mirror on Mac. For dual extended displays on Mac, you need to use one HDMI port plus the downstream Thunderbolt 4 port, and you still need a Mac host that supports more than one external display.

That Mac caveat matters because Thunderbolt docks are often bought for MacBooks. The Thunderbolt 3 Dock Pro has its own Apple Silicon limitation, because base M1, M2, M3, and M4 MacBook models still support only one native external display. But the dock’s dual-display path is less awkward on capable Macs: one monitor through DisplayPort and one through downstream Thunderbolt 3.

The score difference is not huge. A 7.0 versus 6.5 result is a close call, not a blowout. The older Belkin wins because it has the stronger everyday port mix and avoids the Connect Pro’s biggest macOS trap.

Display support: HDMI convenience versus Mac reality

Display support is the main reason to choose one over the other.

The Belkin Thunderbolt 3 Dock Pro supports one 5K@60Hz display through the downstream Thunderbolt 3 port, one 4K@60Hz display through DisplayPort or downstream Thunderbolt 3, and dual 4K@60Hz using one monitor on DisplayPort and a second monitor on the downstream Thunderbolt 3 port. That is a classic Thunderbolt dock layout. It is adapter-heavy if your monitors only have HDMI, but it is easy to understand.

The Belkin Connect Pro TB4 supports more display modes. Its YAML lists one 8K@30Hz display through the downstream Thunderbolt 4 port, dual 4K@60Hz through two HDMI 2.0 ports on Windows, dual 4K@60Hz through one HDMI plus downstream Thunderbolt 4 on compatible Macs, and triple 4K@60Hz using two HDMI ports plus downstream Thunderbolt 4 on host laptops that support triple display output.

For Windows, that gives the Connect Pro TB4 the better display story. Two HDMI ports make a two-monitor office setup simpler, and the dock can go beyond two displays on the right host.

For Mac, the Connect Pro TB4 is much messier. Its product data says dual HDMI extension does not work on macOS because macOS does not support MST. The two HDMI ports mirror instead of extending the desktop. Belkin’s workaround is to use one HDMI plus the downstream Thunderbolt 4 port for dual extended displays, and that still requires a Mac with enough native external-display support. The same YAML also notes common HDMI monitor signal loss after sleep or wake on macOS.

The Thunderbolt 3 Dock Pro is not magic on base Apple Silicon either. Its known incompatibilities say base Apple Silicon MacBooks are limited to one native external display. But if you have an Intel Mac or a higher-end Apple Silicon MacBook, the F4U097’s DisplayPort plus Thunderbolt path is the cleaner setup.

Display verdict: Connect Pro TB4 for Windows HDMI desks. Thunderbolt 3 Dock Pro for users who would rather deal with adapters than macOS MST behavior.

Ports: older Belkin gives you more legacy USB and faster SD

The Thunderbolt 3 Dock Pro has the better port mix for older accessories. It has one USB-A 3.1 port, four USB-A 3.0 ports, and one USB-C 3.1 port. Belkin’s YAML calls out five USB-A ports as a moderate feature advantage because they work well for older keyboards, mice, drives, and accessories.

The Connect Pro TB4 has one USB-C 3.1 port with 20W accessory charging, two USB-A 3.1 ports, and two USB-A 2.0 ports. That is still enough for a normal desk, but two of its USB-A ports are slower USB 2.0 ports. If you have several USB storage devices, capture cards, webcams, or audio interfaces, the older dock’s USB-A layout is easier to live with.

Video ports are the opposite. The Thunderbolt 3 Dock Pro has one DisplayPort output and one Thunderbolt 3 video path. It has no HDMI output, and the product data flags that as a con because most HDMI monitor setups need adapters. The Connect Pro TB4 has two HDMI 2.0 outputs and one downstream Thunderbolt 4 port, which is more convenient if your desk already uses HDMI monitors.

Both docks have Gigabit Ethernet. Neither gives you 2.5GbE. That is a real limitation compared with stronger Thunderbolt 4 docks like the CalDigit TS4, but between these two Belkin models, networking is a tie.

Both docks also have a 3.5mm combo audio jack. The card reader is not a tie: the Thunderbolt 3 Dock Pro has a UHS-II SD reader, while the Connect Pro TB4 has SD 3.0 / UHS-I. If you move photos or video from SD cards, the older dock has the better media port.

Port verdict: Thunderbolt 3 Dock Pro for USB-A density and faster SD. Connect Pro TB4 for built-in HDMI and USB-C accessory charging.

Charging and power: 90W beats 85W, but not by much

The Connect Pro TB4 has the higher host charging rating: 90W through the Thunderbolt 4 upstream connection. The Thunderbolt 3 Dock Pro delivers up to 85W through its rear Thunderbolt 3 computer port.

That 5W gap is real, but it should not decide the purchase by itself. Both docks cover most 13-inch, 14-inch, and many 15-inch or 16-inch laptops during normal office use. Neither is designed as a workstation-class 140W or 180W dock. If your laptop regularly needs more than 90W under sustained load, you should look at a different class of dock.

The power supplies are different. The Thunderbolt 3 Dock Pro includes a 170W power adapter, while the Connect Pro TB4 uses a 120W external power supply. Both require external power through a DC barrel input. Neither is a bus-powered travel hub.

The F4U097 product data includes a practical setup warning: connect the laptop to the rear Thunderbolt 3 port marked with the computer icon if you want host charging. Plugging into the wrong rear Thunderbolt port can leave the laptop uncharged.

Charging verdict: Connect Pro TB4 wins narrowly at 90W, but the difference is too small to outweigh display behavior and port layout for most buyers.

Compatibility: Thunderbolt 4 certification does not solve every problem

Thunderbolt 4 certification is the Connect Pro TB4’s cleanest advantage. The dock is USB4 compliant and backward compatible with Thunderbolt 3, USB 3.0, and USB 2.0. Its YAML also says Windows 10 RS3 or later gets full support with Thunderbolt 4 or USB4 equipped PCs, including MST-based dual and triple display output.

That makes it a good fit for modern Windows laptops. If you have a Windows machine with Thunderbolt 4 or USB4 and two HDMI monitors, the newer dock is easier to recommend.

The Thunderbolt 3 Dock Pro is older. Belkin lists Windows 8 and Windows 10 as tested, plus macOS 10.12 through 10.14 in the original support range. Modern systems normally still support Thunderbolt docks, but the YAML properly treats the F4U097 as a legacy product. It also notes that Linux is not officially listed by Belkin and that USB-C fallback depends on DisplayPort Alt Mode and USB Power Delivery.

The surprise is that the Connect Pro TB4 has the harsher Mac warnings. Its cons say dual HDMI does not extend displays on macOS, making it a poor choice for Mac users. Its common issues say dual HDMI mirroring on macOS is common and severe, and HDMI monitor loss after sleep or wake is common on macOS.

The Thunderbolt 3 Dock Pro has occasional sleep or wake display detection issues too. It is not free of dock-class problems. But its Mac limitation is mostly the Apple Silicon native-display ceiling and older Thunderbolt behavior, not a dual-HDMI MST design that conflicts with macOS.

Compatibility verdict: Connect Pro TB4 for modern Windows and USB4 expectations. Thunderbolt 3 Dock Pro for a simpler Mac-capable Thunderbolt desk, assuming your Mac supports the number of displays you want.

Value: buy the older dock only when the price is right

The Thunderbolt 3 Dock Pro launched at $349.99. The Connect Pro TB4 launched at $399.99, and its YAML notes a current Belkin-store price of $299.99 at the time that product review was written. The older F4U097 now competes mostly on used, discounted, or remaining retail stock.

That last point is important. The Thunderbolt 3 Dock Pro wins this head-to-head because it has the better score and a more useful mix for many desks, not because an old Thunderbolt 3 dock should cost the same as a strong current Thunderbolt 4 model.

If the F4U097 is priced near newer top-tier docks, skip it. Its own verdict says that if the price is close to a CalDigit TS4, OWC Thunderbolt 4 Dock, or Belkin’s newer Thunderbolt 4 models, you should buy the newer dock instead. That is still true. It lacks Thunderbolt 4 certification, lacks HDMI, lacks 2.5GbE, and sits in a category where newer alternatives can offer more downstream Thunderbolt ports and better long-term support.

The Connect Pro TB4 also has a value problem. Its product data says competing docks like the Plugable TBT4-UD5 can offer similar specs for less, and the Ugreen Revodok Max 213 adds a second downstream Thunderbolt 4 port. Belkin’s brand and aluminum build help, but the dock’s Mac display limitations make the price harder to accept.

Value verdict: Thunderbolt 3 Dock Pro if discounted enough. Connect Pro TB4 only if you specifically want Belkin, Thunderbolt 4, and dual HDMI for Windows.

Choose the Belkin Thunderbolt 3 Dock Pro if

• You found the F4U097 at a meaningful discount versus newer Thunderbolt 4 docks.
• You need five USB-A ports for older peripherals.
• You want a UHS-II SD reader built into the dock.
• Your monitor setup can use DisplayPort plus downstream Thunderbolt, or you are fine using adapters.
• You use an Intel Mac, a higher-end Apple Silicon Mac, or a Windows Thunderbolt laptop that supports dual native displays.
• You prefer a proven Thunderbolt 3 workstation dock over the Connect Pro’s Mac-hostile dual HDMI behavior.

Choose the Belkin Connect Pro TB4 if

• You run Windows and want two HDMI monitors without adapters.
• You specifically want Thunderbolt 4 certification and USB4 compliance.
• You need the slightly higher 90W host charging rating.
• You want single 8K@30Hz support through downstream Thunderbolt 4.
• You can use its one HDMI plus downstream Thunderbolt 4 path on Mac and understand the MST limitation.
• You value a newer Belkin dock with a clean aluminum chassis more than UHS-II SD or extra USB-A bandwidth.

Final verdict: the older Belkin is the better all-around pick

The Belkin Thunderbolt 3 Dock Pro is the better choice for most buyers comparing only these two Belkin docks. It scores higher, has more useful USB-A connectivity, includes a faster UHS-II SD reader, and avoids the Connect Pro TB4’s biggest Mac display pitfall. Its 85W charging and dual 4K@60Hz Thunderbolt display support are still enough for many desks.

The Belkin Connect Pro TB4 is still the right answer for one specific buyer: a Windows user who wants dual HDMI, Thunderbolt 4 certification, and 90W charging from a Belkin-branded dock. For that setup, it is simpler and newer.

For everyone else, the older F4U097 is the more balanced Belkin dock as long as the price reflects its age. If both are expensive, widen the search before buying. The CalDigit TS4, OWC Thunderbolt 4 Dock, and other current Thunderbolt 4 options may make more sense than either Belkin model.
