How to Connect Dual 4K Monitors with Anker 563 USB-C Hub

Working with a single monitor can feel cramped, especially when you're juggling spreadsheets, code, or creative tools. Adding a second 4K display dramatically boosts your productivity, but many laptops only have one or two video outputs. That's where a USB-C hub like the Anker 563 comes in. It turns a single USB-C port into a powerful docking solution that can drive two 4K monitors simultaneously.

In this guide, we'll walk you through everything you need to know about setting up dual 4K monitors with the Anker 563 USB-C Hub. We'll cover compatibility, step-by-step connection instructions for both Mac and Windows, and common troubleshooting tips so you can get your multi-monitor workspace running smoothly.

Why Choose the Anker 563 USB-C Hub for Dual 4K?

The Anker 563 USB-C Hub is a versatile 11-in-1 docking station that offers two HDMI ports, both capable of outputting 4K resolution. This makes it an ideal choice for professionals who need high-resolution displays for detailed work. Whether you're a video editor, financial analyst, or software developer, having two crisp 4K screens can transform your workflow.

One of the key advantages of the Anker 563 is its plug-and-play design. You simply connect the hub to your laptop's USB-C port (or Thunderbolt 3/4 port) and then attach your monitors to the HDMI outputs. There's no need for complex software or drivers, and it works with both macOS and Windows. Plus, the hub also provides additional USB-A ports, an Ethernet port, and SD card slots, making it a central docking station for all your peripherals.

• Two HDMI ports with 4K@60Hz support (when using compatible laptops)
• 11-in-1 functionality: USB-A, USB-C, Ethernet, SD/TF card slots, and more
• Compatible with MacBook, Windows laptops, and even some tablets

What You'll Need Before You Start

Before you begin, gather the following items: your laptop (with a USB-C port that supports DisplayPort Alt Mode or Thunderbolt), the Anker 563 USB-C Hub, two HDMI cables (or HDMI-to-DisplayPort adapters if your monitors only have DisplayPort), and two 4K monitors. It's also a good idea to have your laptop plugged into power, as driving dual 4K displays can be power-hungry.

Check your laptop's specifications to ensure it supports dual 4K output. Most modern MacBook Pro and MacBook Air models (M1 or later) support dual external displays, but some Windows laptops may have limitations. For example, if your laptop only has a USB-C port that supports USB 3.1 Gen 1 (5Gbps), it may not have enough bandwidth for dual 4K at 60Hz. In that case, you might need to run one monitor at 4K and the other at 1440p, or use a Thunderbolt 3/4 port for full performance.

• Laptop with USB-C port supporting DisplayPort Alt Mode or Thunderbolt
• Two HDMI cables (ensure they are high-speed, preferably HDMI 2.0)
• Two 4K monitors with HDMI inputs

Step-by-Step: Connecting Dual 4K Monitors

Follow these steps to set up your dual 4K monitors with the Anker 563. First, connect the Anker 563 USB-C Hub to your laptop using the included USB-C cable. The hub should be recognized automatically. Next, connect one HDMI cable from the first monitor to the HDMI 1 port on the hub, and the second HDMI cable from the other monitor to the HDMI 2 port. Make sure both monitors are powered on and set to the correct HDMI input source.

Once connected, your laptop should detect both monitors. On macOS, go to System Preferences > Displays to arrange and configure them. On Windows, right-click on the desktop and select Display Settings. You may need to adjust the resolution to 3840x2160 and set the refresh rate to 60Hz. If you don't see the option for 4K, check your cable connections and ensure your laptop's graphics driver is up to date.

• For MacBook users: Use a USB-C to USB-C cable that supports DisplayPort Alt Mode (the included cable works).
• For Windows users: Ensure your laptop's USB-C port supports DP Alt Mode; if not, consider using a Thunderbolt port.

Troubleshooting Common Issues

If you're not getting a signal on one or both monitors, try the following: First, verify that your laptop's USB-C port supports DisplayPort Alt Mode. You can check this in your laptop's manual or by searching online. Second, try swapping the HDMI cables to rule out a faulty cable. Third, ensure that your monitors are set to the correct input source (HDMI 1 or HDMI 2).

Another common issue is that both monitors show the same image (mirrored) instead of an extended desktop. To fix this, go to your display settings and choose 'Extend these displays' instead of 'Duplicate'. If one monitor is not detected, try disconnecting and reconnecting the hub, or restarting your laptop. Also, make sure your laptop's graphics drivers are updated to the latest version.

• If only one monitor works, check if your laptop supports dual display output via a single USB-C port.
• Use high-quality HDMI cables (certified for 4K) to avoid signal degradation.

Maximizing Your Dual 4K Setup

Once your dual 4K monitors are working, you can optimize your setup for productivity. Use the built-in display arrangement tools to position the monitors to match your physical setup. On macOS, you can drag the display icons to the correct positions. On Windows, you can do the same in Display Settings. You can also adjust the scaling to make text and icons larger if needed.

If you're using a laptop that supports charging via USB-C, the Anker 563 also supports Power Delivery (PD) pass-through, so you can keep your laptop charged while using the hub. This is especially useful for MacBook users who only have USB-C ports. Additionally, you can connect other peripherals like a mouse, keyboard, or external storage to the hub's USB-A ports, turning your laptop into a full-fledged desktop workstation.

• Use the hub's Ethernet port for a stable wired internet connection.
• Connect your keyboard and mouse to the USB-A ports to free up your laptop's built-in ports.

Setting up dual 4K monitors with the Anker 563 USB-C Hub is a straightforward process that can dramatically improve your productivity. By following the steps in this guide, you'll have a powerful multi-monitor workstation in no time. If you're looking for a reliable hub to handle your dual 4K needs, the Anker 563 is an excellent choice. Check it out on Anker's website to see if it fits your setup.
