Belkin Connect Pro TB4 Dock Review 2026
The Belkin Connect Pro Thunderbolt 4 Dock is a 12-port docking station that turns a single Thunderbolt 4 cable into a full desktop setup. Model INC006 launched in February 2022 at $399.99 and has since dropped to $299.99 at Belkin's own store. The dock packs dual HDMI 2.0 ports, a downstream Thunderbolt 4 port, USB-C 3.1 Gen 2 with Power Delivery, two USB-A 3.1 ports, two USB-A 2.0 ports, Gigabit Ethernet, an SD card reader, and a 3.5mm combo audio jack. Power delivery tops out at 90W to the host laptop, which covers most 13 to 16-inch machines. Display output supports a single 8K at 30Hz, dual 4K at 60Hz via the two HDMI ports on Windows, or triple display when combining HDMI with the downstream Thunderbolt 4 port on compatible laptops. The dock is USB4 compliant and backward compatible with Thunderbolt 3 and USB 3.0. Belkin includes a 0.8m Thunderbolt 4 cable and a 120W external power supply in the box. The aluminum and black chassis measures roughly 200mm x 73mm x 34mm and looks right at home on a professional desk. One important caveat: Mac users face real limitations here. M1 MacBooks support only one external display natively, and the dual HDMI ports on this dock rely on MST, which macOS does not support. That means Mac users need to use the downstream Thunderbolt 4 port plus one HDMI for dual monitors, giving up the second HDMI entirely.
Pros & Cons
What We Like
- 90W Power Delivery charges most 13 to 16-inch laptops at near full speed
- Dual HDMI 2.0 ports allow two-monitor setup without adapters on Windows
- 12 ports including Gigabit Ethernet and SD card reader in a single dock
- Premium aluminum build quality that looks professional on any desk
- Thunderbolt 4 certified with USB4 compliance and backward compatibility
- Belkin's optional dock utility software adds network security features for enterprise use
What Could Be Better
- Dual HDMI does not extend displays on macOS, only mirrors - making this a poor choice for Mac users
Workaround: Use one HDMI port plus the downstream Thunderbolt 4 port for dual extended displays on Mac. Requires M1 Pro/Max or later chip.
- Only one downstream Thunderbolt 4 port limits daisy-chaining and monitor connectivity
Workaround: If you need multiple TB4 downstream ports, consider the Ugreen Revodok Max 213 or CalDigit TS4.
- At $299.99 street price, competing docks like Plugable TBT4-UD5 offer similar specs for less
- HDMI signal loss after sleep/wake cycles reported by multiple users
Workaround: Unplug and replug the HDMI cable from the dock to restore signal. Keep firmware and OS updated.
- SD card reader is UHS-I only, no UHS-II support for faster media transfers

Compatibility

Supported on Intel and Apple Silicon MacBooks. However, dual HDMI display extension does not work on macOS due to lack of MST support. Use HDMI + downstream TB4 for dual monitors.
Known Issues
Limited to single external display via HDMI
Dual HDMI does not extend desktop on macOS
Limited functionality
Our Verdict
Good
The Belkin Connect Pro Thunderbolt 4 Dock is a mixed bag. For Windows users who want dual HDMI output, 90W charging, and a clean port spread from a reputable brand, it delivers. The build quality is excellent, the aluminum chassis runs cool enough, and the 12 ports cover most desktop needs without reaching for dongles. Gigabit Ethernet and the SD card reader fill gaps that many laptops skip. At the current $299.99 street price, it sits in competitive territory against docks like the Plugable TBT4-UD5 (which offers similar specs for less) and the Ugreen Revodok Max 213 (which adds a second Thunderbolt 4 downstream port). The single downstream Thunderbolt 4 port is a real limitation if you daisy-chain TB4 devices. Where this dock falls apart is on macOS. Dual HDMI does not extend displays on Apple Silicon MacBooks because macOS lacks MST support. Users report needing to unplug and replug HDMI cables to get signal after sleep/wake cycles. Reddit threads are full of frustrated Mac owners calling this dock a mistake. Tom's Guide specifically flagged it as a "no-go for Mac users." If you run Windows with a Thunderbolt 4 laptop and want a reliable, good-looking dock with dual HDMI, the Belkin Connect Pro earns a recommendation. If you are on a Mac, look at the CalDigit TS4 or OWC Thunderbolt 4 Dock instead. The Belkin brand carries weight and the 2-year warranty provides peace of mind, but the competition offers more for the money at this price point.
