Frequently Asked Questions
Q1Does the CalDigit TS4 work with the Mac Mini M4 Pro?
Yes — the Mac Mini M4 Pro has two Thunderbolt 4 ports and the TS4 connects to either. You get 98W pass-through charging (useful if you power the Mac Mini via USB-C), 2.5GbE networking, and all 18 ports active simultaneously. It's the most capable single-cable dock for the M4 Pro.
Q2Can the TS4 run dual monitors from a Mac Mini?
Yes. From the TS4's Thunderbolt 4 downstream port and DisplayPort output, you can drive two 6K displays simultaneously. On Mac Mini M4 Pro which supports up to three external displays, the TS4 handles two of them while the third connects directly to the Mac Mini's HDMI port.
Q3Does the CalDigit TS4 work with Windows mini PCs?
Yes, with caveats. Windows mini PCs with Thunderbolt 4 (like GEEKOM AI A7 Max) get full compatibility. Mini PCs with USB4 but not certified TB4 may see reduced display or port performance. Check your mini PC's port spec before purchasing.
Q4How does the TS4 compare to the Anker 777 Thunderbolt dock?
TS4 has 18 ports vs 12 on the Anker 777, and 98W vs 90W charging. TS4 also adds 2.5GbE vs Gigabit Ethernet on the Anker. The Anker 777 costs $100 less — if you need fewer ports and standard Ethernet, it's the better value.
