Thunderbolt 5 Dock Comparison:
Five High-End Docks Reviewed
iVANKY's FusionDock Max 2 and Ultra, CalDigit's TS5 and TS5 Plus, and UGREEN's Revodok Maxidok 17-in-1 — side by side on displays, USB-A count, Ethernet, built-in storage, and price. Whether you're running a 4-monitor creative setup, a home office, or a live trading desk, here's what actually matters once you get past the marketing spec sheet.
I'm currently running four external displays on my own trading desk — three high-end 5K monitors plus a 43" Samsung Frame TV pulling double duty as a dashboard. (You can see the full setup on my Trading Workstation page.) All four were already owned and repurposed for this desk, not bought new for it — which meant the real question for me wasn't "which dock has the most features," it was "which dock can actually drive four displays I already own, on the Mac I'm about to upgrade to, without paying for headroom I'll never use." That's the lens this comparison is written through, even though it's broadly useful for any 4-display Mac setup, trading or otherwise.
All five docks here are capable Thunderbolt 5 hardware. The differences come down to what you're actually optimizing for: display count, USB-A peripheral support, built-in storage, or raw networking speed. For the most common case — driving 4 displays on an M5 Max MacBook Pro plus a full peripheral lineup — the iVANKY FusionDock Max 2 hits the best balance of price and capability. But three of the other four docks win outright for specific use cases, covered below.
Both iVANKY docks (FusionDock Max 2 and Ultra) are Apple Silicon–only — no PC, no Intel Mac, full stop. If you're on Windows or an older Intel-based Mac, the CalDigit TS5, TS5 Plus, and UGREEN Maxidok are cross-platform and the only three of these five actually available to you.

I currently use the FusionDock Max 2 on my own desk; the other four are included based on spec research and published reviews, not hands-on testing on my part. I'll add firsthand notes as I get time with the others.

The FusionDock Max 2 natively supports 4 displays on M5 Max — either 3 downstream Thunderbolt 5 ports plus HDMI, or all 4 via Thunderbolt with one daisy-chained. The CalDigit TS5 and TS5 Plus also officially support up to 4 on M5 Max, but getting past the base dual-display config means using one of the dock's own spare Thunderbolt ports as an extra video pass-through — not a dedicated 3rd/4th output. Only the FusionDock Ultra's dual-chip design delivers all 4 without any of this. The UGREEN Maxidok is the clear exception in the other direction: capped at 2 displays on Mac regardless of chip generation, since its video output runs through only 2 spare Thunderbolt ports plus a DisplayPort 2.1 jack built primarily for Windows multi-stream setups.
From my own setup specifically: I'm running two LG UltraFine 5K displays plus an Apple Studio Display 5K through the Max 2 — three demanding 5K Thunderbolt displays at once. iVANKY's own site flags exactly this combination as a known edge case, recommending against pairing two LG/Samsung 5K panels together on this dock. That's likely why my setup needed a workaround, not a general limitation of the dock itself — worth knowing if your own setup leans on multiple high-bandwidth 5K monitors specifically.
* Reaching the 4th display on CalDigit docks requires using a spare Thunderbolt port for an extra video connection — see note above. ** USB-C port counts for both iVANKY docks are reported inconsistently across manufacturer listings and reviews, depending on whether Thunderbolt-capable ports are counted as dual-purpose USB-C; treat these as approximate.
For a dedicated trading setup — multiple chart and dashboard displays, a browser-based broker platform, and accessory peripherals like a Stream Deck — the calculus narrows considerably. Two specs matter far more than the rest of the spec sheet: how many displays the dock actually drives, and how many Thunderbolt ports on the Mac itself get tied up doing it.
The right dock here isn't about avoiding the most expensive option — the TS5 is the exact same price as the Max 2, and the Ultra isn't even double. It's about matching what the dock actually does to what your setup actually needs. I went with the Max 2 because it covers what my desk needs today — enough USB-A for a full peripheral lineup, without paying for 10GbE or a dual USB controller I'd never touch. If your needs are genuinely different — more ports, faster networking, built-in storage — one of the other four is the better fit, regardless of price.
