USB4 docks matter when your Windows laptop exposes a 40Gbps USB4 or Thunderbolt port and you want dual 4K without buying a $400 CalDigit. The gotchas: some docks are Windows-only, “triple 4K” often means 30Hz, and Mac compatibility is frequently weak or unsupported.
Best for: Windows 10/11 USB4 or TB4 notebooks that want dual 4K@60 + ~100W charging.
Not for: Base Apple Silicon MacBooks (wrong platform for most USB4 multi-display claims) or USB-C Alt Mode-only ports that are not full USB4/TB.
Short answer: For a Windows laptop with a USB4 or Thunderbolt 4 port that needs dual 4K at 60Hz, the Anker 568 is the lead pick on this page.
FAQ
Does the Anker 568 do dual 4K on a Mac?
Anker does not recommend this dock for MacBooks. Treat it as a Windows dock and choose a Thunderbolt 4 dock for macOS.
Is USB4 the same as Thunderbolt 4?
No. Thunderbolt 4 is a stricter certification that includes USB4, and USB4 docks vary in video and charging features.
Do Windows USB4 laptops need DisplayLink for dual 4K?
Usually no, if the port is full USB4 or Thunderbolt 4. DisplayLink is the workaround for base Apple Silicon Macs and for monitors beyond a chip’s native limit.
Quick picks
- Best Windows USB4 value: Anker 568
- Driverless USB4 dual DisplayPort angle: StarTech USB4 dual-4K class docks
- TB4 that also plays nice on Mac: Plugable TBT4-UD5 / CalDigit TS4
- Dense mid-tier: UGREEN Revodok Max 213
- Portable USB4 dual HDMI: Cable Matters 40Gbps hub (travel, not full desk dock)
1. Anker 568 — lead pick for Windows
USB4 40Gbps, ~100W PD, 2×DP 1.4 + HDMI. On Windows: dual 4K@60 or triple 4K@30. Anker explicitly does not recommend it for MacBooks — treat it as a Windows dock.
Best for: XPS / ThinkPad / EliteBook USB4 desks.
Not for: macOS dual-display plans.
2. StarTech USB4 / TB4 options
StarTech’s driverless USB4 dual-display docks target Windows/ChromeOS zero-touch rollouts (often not macOS). Their Thunderbolt 4 models add broader Mac dual-4K paths on Pro/Max chips. Read the OS line on the SKU before you standardize a fleet.
3. Plugable TBT4-UD5 — TB4 dual HDMI workhorse
Thunderbolt 4 certified, dual HDMI 4K@60 on capable hosts, ~100W charging. Excellent when you want one SKU that can serve Windows USB4/TB4 and Mac Pro/Max users.
4. UGREEN Revodok Max 213 & Anker Prime 14-in-1
Feature-dense alternatives when you want more USB ports or a different video mix. Confirm USB4 vs Thunderbolt branding and dual 4K@60 claims for Windows specifically.
5. Premium ceiling: CalDigit TS4
If budget expands and you want 2.5GbE + SD UHS-II + three TB4 ports, jump to CalDigit. It is TB4 rather than “USB4-only,” but it sits at the top of the same dual-4K desk category.
6. Travel USB4 dual HDMI
Cable Matters’ portable 40Gbps dual-HDMI USB4 hub is for bags, not as a full Ethernet/SD desk dock. Pair with a desk dock if you live on wired LAN.
Buying tips
- Confirm the laptop port is USB4 or Thunderbolt — not charge-only USB-C.
- Believe dual 4K@60 claims; treat triple 4K@60 ads with suspicion unless the dock documents DSC/host limits.
- Prefer docks with a robust included PSU; “PD passthrough only” hubs often undercharge.
- Use short certified USB4/TB4 cables.
FAQ
Is USB4 the same as Thunderbolt 4?
Related, not identical. TB4 is a stricter certification that includes USB4; USB4 docks vary in video/PD features.
Will Anker 568 do dual 4K on Mac?
Anker does not recommend it for Mac — choose a TB4 dock instead.
Do I need DisplayLink for Windows USB4 dual 4K?
Usually no on full USB4/TB4 hosts; DisplayLink is the Mac base-chip / extra-monitor tool.
