The Anker 568 exists for a very specific frustration: you have a modern Windows laptop with a real USB4 or Thunderbolt port, you want dual 4K@60 from one cable, and you do not want to fund CalDigit’s entire port museum to get there. Eleven ports, 40Gbps upstream, up to ~100W laptop charging, and a display layout of two DisplayPort 1.4 outputs plus HDMI make it one of the clearest Windows USB4 value stories still circulating in 2026 research guides.
Anker’s own guidance is equally clear about who should walk away: MacBook owners. This is a Windows-first dock. Treat marketing that says “works on everything” as someone else’s problem.
Who it’s for
- Windows 10/11 notebooks with full USB4 or Thunderbolt 4 controllers (XPS, many ThinkPads, EliteBooks, Surface TB models, etc.)
- Hybrid workers who want dual 4K productivity panels plus strong PD without a $400 dock
- Desks that prioritize video + USB + Gigabit Ethernet over SD card readers
- Buyers who understand “triple 4K” on this class of dock usually means 30Hz, not three silky 60Hz panels
Who should skip it
- Any MacBook docking plan — Anker does not recommend the 568 for Mac
- Creators who ingest from UHS-II SD all day (no reader here)
- Dell fleets that need ExpressCharge ~130W
- Users whose “USB-C” port is charge/data only without DisplayPort Alt Mode / USB4 video budget
Verdict (research)
As a Windows USB4 dual-4K desk dock, the Anker 568 earns its “best value” slot in our wider roundups. It is not the port king, not the Mac dock, and not the Dell fleet dock. It is the pragmatic middle that ships the bandwidth Windows users actually buy docks for.
Ports table
| Feature | Anker 568 (A8399) |
|---|---|
| Host link | USB4 up to 40Gb/s |
| Display outputs | 2× DisplayPort 1.4 + HDMI |
| Dual 4K@60 | Yes on capable Windows hosts |
| Triple display | Up to triple 4K@30 (not triple 4K@60) |
| Laptop charging | Up to ~100W PD |
| USB | USB-C (incl. device charging on some ports) + USB-A |
| Ethernet | Gigabit |
| SD / audio jack | Neither |
Pros
- USB4 bandwidth aimed at real dual 4K@60 Windows desks
- ~100W PD covers a wide band of modern ultraportables and 14″ machines
- Usually priced under premium TB4 flagships
- Honest Windows positioning reduces Mac return drama — if you read the box
- DP-first layout suits office monitor farms that standardized on DisplayPort
Cons
- Not for Mac
- No SD reader, no 3.5mm jack
- Triple-display mode trades refresh rate
- Fewer Thunderbolt peripheral tricks than a fully certified TB4 dock with downstream TB ports
- Requires a healthy included PSU — starve the dock and everything feels flaky
Windows display planning
Plan your desk around dual 4K@60. If a third monitor is mandatory, assume 4K@30 or a lower resolution on at least one panel unless your specific host + cable + DSC combination is validated. Hosts that only expose USB-C Alt Mode without a USB4/TB controller will not magically grow 40Gbps of video budget because the dock’s marketing page says USB4.
Setup tips that prevent returns
- Confirm Device Manager / OEM specs show USB4 or Thunderbolt before buying.
- Use the Anker power adapter that ships with the dock.
- Attach the two primary 4K panels to the DisplayPort outputs first; add HDMI last.
- Update laptop chipset / Thunderbolt firmware if mirrors fail or one panel drops to 30Hz unexpectedly.
- Keep a short certified USB4/TB4 cable in the drawer — passive charge cables cause “dock is broken” tickets.
Anker 568 vs alternatives
- vs StarTech USB4 dual-display docks: StarTech often pitches driverless Windows/ChromeOS fleet imaging; compare OS support lines carefully.
- vs Plugable TBT4-UD5: Choose Plugable when you need a Thunderbolt 4 certified story that also covers Mac Pro/Max users.
- vs CalDigit TS4: CalDigit when you need 2.5GbE, SD UHS-II, and Mac trust at premium pricing.
- vs Dell WD22TB4: Dell when ExpressCharge and commercial Dell matrices matter more than USB4 value pricing.
If you are migrating from a cheap dual-HDMI USB-C hub that only delivered 4K@30, the Anker 568’s job is to restore 60Hz stability on two panels while keeping the laptop topped up. That only happens when the host port is truly USB4/TB4 and the dock’s own power brick is in the loop. Treat those two checks as non-negotiable; everything else is preference about which USB ports face forward.
FAQ
Can I force the 568 to work well on a MacBook Pro?
Anker does not recommend it. Buy a Thunderbolt 4 dock from our MacBook guide instead.
Is USB4 required?
For the dual 4K@60 experience you saw in the brochure, yes — full USB4/TB4 host link.
Will three 4K@60 monitors work?
Not as a reliable planning assumption on this dock. Dual 4K@60 or triple 4K@30.
