Frequently Asked Questions
Does the INC031KQSGY work with a Thunderbolt 3 laptop?
No. Belkin lists compatibility with Thunderbolt 5 and Thunderbolt 4 hosts and explicitly excludes Thunderbolt 3 laptops and monitors.
How many monitors can I use with a MacBook?
It depends on the chip: base M1, M2 and M3 MacBooks support one external display, M4 and M1–M4 Pro/Max support two, and triple displays are limited to the newest Pro/Max chips. Windows Thunderbolt 5 laptops can run three 4K@144Hz displays.
What is the difference between the INC031 and the Belkin Connect Universal 14-Port Dock (INC028)?
The INC031 uses native Thunderbolt 5 video, 80–120Gbps data, 140W charging and 2.5Gb Ethernet; the INC028 uses DisplayLink for dual 4K on any USB-C laptop with 100W charging and 1Gb Ethernet.
Singular Expert Insight
This is a dock to buy for the next five years: Thunderbolt 5 bandwidth, high-refresh triple-display support and 140W charging cover even 16-inch performance laptops. If your fleet is mostly older USB-C or Thunderbolt 3 machines, a universal DisplayLink dock is the more compatible (and cheaper) choice. Compare more
