Best Dual Monitor Docking Station for Samsung Galaxy Book4
Your Samsung Galaxy Book4 is a portable powerhouse, but if you’re like me, you probably find the limited port selection a bit stifling when it’s time for serious creative work. Transitioning from a mobile editing rig to a full dual-monitor setup shouldn’t feel like a chore. I’ve tested dozens of configurations, and for the Book4, the CalDigit TS4 is the absolute gold standard. In this guide, I’ll help you navigate Thunderbolt 4 bandwidth and power delivery to find the perfect desktop anchor for your Samsung ecosystem.

Best Dual Monitor Docking Station for Samsung Galaxy Book4: Detailed Reviews
CalDigit TS4 View on Amazon
The CalDigit TS4 is, quite frankly, the king of the mountain. Released as the successor to the legendary TS3+, this Thunderbolt 4 beast is the perfect companion for the Galaxy Book4’s high-speed ports. I find this dock exceptional for photography workflows because of the front-facing UHS-II SD and microSD card slots—you can offload cards from your camera and drone simultaneously without reaching behind the unit. It delivers a massive 98W of power, which is more than enough to keep even the Galaxy Book4 Ultra charged during heavy video rendering sessions. You’ll notice that it handles dual 4K monitors at 60Hz with zero flicker, a common ghost in cheaper docks. The aluminum chassis acts as a giant heat sink, which is vital when you have multiple drives and displays connected. It’s expensive, yes, but it eliminates every bottleneck your laptop has.

Anker 778 Thunderbolt Docking Station View on Amazon
If the CalDigit is a bit too rich for your blood, the Anker 778 is a fantastic middle ground that doesn’t sacrifice the “must-haves.” This 12-in-1 dock is specifically designed to maximize Thunderbolt 4 bandwidth. What I love about this model is the inclusion of an 8K HDMI port alongside two DisplayPorts, giving you immense flexibility in how you connect your dual monitors. For Galaxy Book4 users, the 100W charging is a huge win, ensuring your battery stays at 100% even during intensive tasks. The design is much slimmer than the CalDigit, which helps keep a clean desk aesthetic. One minor drawback is that it lacks an SD card slot on the front, which might be a dealbreaker for some photographers, but for general productivity and high-resolution display support, the value proposition here is unmatched. It’s reliable, runs cool, and handles data transfers at a blistering 40Gbps.

Plugable USB-C Dual HDMI Docking Station View on Amazon
Budget docks often struggle with dual displays on Windows laptops, but the Plugable UD-3900Z is the exception. It uses DisplayLink technology, which essentially acts as its own graphics driver to push dual 1080p monitors. This is an “honest” dock—it isn’t going to give you 4K at 120Hz or Thunderbolt speeds, but if you just need two screens for spreadsheets, Chrome tabs, and Zoom calls, it’s remarkably stable. For the Samsung Galaxy Book4, it provides a simple one-cable solution for your peripherals. The big trade-off here is the lack of laptop charging (Power Delivery). You’ll still need to plug your Samsung charger into the other side of the laptop. However, at this price point, having a reliable dual-HDMI output and six extra USB ports is a massive upgrade over a cheap “dongle” that might overheat and drop your connection halfway through the day.

Razer Thunderbolt 4 Dock Mercury View on Amazon
The Razer Thunderbolt 4 Dock is a stunning piece of hardware, especially in the Mercury White finish which looks incredible next to the Samsung Galaxy Book4’s sleek chassis. Unlike other docks that give you a mix of HDMI and DisplayPort, Razer gives you four pure Thunderbolt 4 ports. This is a dream for “future-proofing.” You can daisy-chain high-speed NVMe drives or connect two high-refresh-rate monitors using USB-C to DP cables. In my experience, Razer’s implementation of Thunderbolt is exceptionally stable for gaming or high-bitrate video editing. It provides 90W of power delivery, which is plenty for the Book4 Pro series. While it lacks the sheer variety of legacy ports found on the CalDigit, its focus on modern, high-speed connectivity makes it the sleekest, most powerful option for those who have already moved entirely to the USB-C/Thunderbolt ecosystem.

Dell WD22TB4 View on Amazon
The Dell WD22TB4 is a workhorse often found in corporate offices, but it’s an excellent pick for the Galaxy Book4 due to its modular design. If the Thunderbolt cable ever frays or breaks, you can actually replace the module rather than buying a whole new dock—a rarity in today’s world. It offers a very generous array of display outputs, including two DisplayPort 1.4 ports and one HDMI 2.0 port, making it incredibly easy to set up dual 4K monitors without needing special adapters. While it is marketed as providing up to 130W for Dell systems, it will reliably provide 90W to your Samsung laptop, which is the industry standard for Thunderbolt 4. I’ve used this dock in environments where it stays on 24/7, and its reliability is top-tier. It’s not the prettiest dock on the list, but it’s arguably the most “sensible” choice for a dedicated home office.

Frequently Asked Questions
Can the Galaxy Book4 handle dual 4K monitors?
Yes, absolutely. Thanks to the Intel Core Ultra processors and Thunderbolt 4 ports, the Galaxy Book4 Pro and Ultra can easily drive two 4K monitors at 60Hz. However, to achieve this through a single cable, you must use a Thunderbolt 4 docking station. Standard USB-C docks often lack the bandwidth to drive two 4K screens simultaneously, frequently dropping the refresh rate to 30Hz, which looks noticeably choppy.
Do I need to use the original Samsung charger with the dock?
If your docking station supports Power Delivery (PD) of 65W or higher (ideally 90W-100W), you do not need to use the original charger. The dock will charge your laptop through the same cable it uses for data and video. However, if you use a budget dock like the Plugable UD-3900Z which doesn’t support PD, you will need to keep your Samsung power brick plugged in.
What is the difference between Thunderbolt 3 and Thunderbolt 4 docks?
While both offer 40Gbps speeds, Thunderbolt 4 is more efficient at handling multiple data streams. A TB4 dock like the CalDigit TS4 can support up to four Thunderbolt ports (one upstream, three downstream), whereas TB3 docks were more limited. For Galaxy Book4 users, TB4 docks offer better compatibility with the laptop’s sleep/wake states and ensure that all ports operate at their maximum rated speeds without interference.
Will these docks work with the base Galaxy Book4 (non-Pro)?
Most will work, but with caveats. The base Galaxy Book4 often uses standard USB-C with DisplayPort Alt Mode rather than full Thunderbolt 4. In this case, a Thunderbolt dock will still function but will be limited to USB-C speeds (10-20Gbps). For the base model, the Plugable UD-3900Z is actually a great choice because its DisplayLink technology bypasses many of the hardware limitations of standard USB-C ports.
Why are my monitors flickering when connected to the dock?
Flickering is almost always caused by a cable issue or bandwidth saturation. Ensure you are using high-quality “Active” Thunderbolt 4 cables or certified HDMI 2.1/DisplayPort 1.4 cables. If you are using a non-Thunderbolt dock with two 4K monitors, the flickering may occur because the dock is trying to push more data than the USB-C port can handle. Switching to a dedicated Thunderbolt 4 dock usually solves this instantly.
Final Verdict
For the ultimate Samsung Galaxy Book4 experience, I highly recommend the CalDigit TS4; its ability to handle high-resolution dual displays while offloading media at lightning speeds is unmatched. If you’re a student or primarily doing office work, the Plugable UD-3900Z offers a reliable dual-screen setup without the premium price tag. For everyone else, the Anker 778 provides the modern Thunderbolt 4 features you need at a very competitive price point.
