Resolution and Connectivity Comparison
Max Resolution
Product B supports dual 4K displays at 60Hz on compatible systems, offering significantly higher clarity for detailed work. Product A maxes out at 2560x1440 at 50Hz for a single display, or 1920x1200 at 60Hz for dual monitors. It does not support 4K output. If you need sharp text and high-density visuals for design or data analysis, Product B provides the superior pixel count and refresh rate. Product A is limited to standard HD and QHD ranges.
Host Interface
Product A uses a hybrid USB 3.0 and USB-C cable, allowing connection to older laptops that lack USB-C video output. It relies on DisplayLink drivers to create virtual displays. Product B requires a host port with USB-C DisplayPort Alt Mode. This native connection method eliminates the need for driver software on supported Windows and ChromeOS systems. If your laptop is newer and supports DP Alt Mode, Product B offers a simpler, driver-free setup. Product A remains the flexible choice for legacy hardware.
Connectivity Ports
Product B provides a 10-in-1 hub layout with one USB-C 5Gbps port, two USB-A 3.0 ports, one USB-A 2.0 port, Gigabit Ethernet, and audio jacks. Product A offers two USB 3.0 ports and four USB 2.0 ports, along with Gigabit Ethernet and audio. Product B includes a K-Lock slot for security. Both include wired internet and audio. Product B offers more modern USB 3.0 speeds for peripherals. Product A provides four USB 2.0 ports, which may suit low-bandwidth devices like keyboards.
Power Delivery
Product B includes an 110W power adapter, which can charge compatible laptops while running dual monitors. This creates a true one-cable workstation experience. Product A does not charge the host laptop. It draws power from the USB connection alone. If you need to power your computer through the dock, Product B is the only viable option. Product A requires you to keep your laptop charger plugged in separately. This makes Product B better for reducing cable clutter on your desk.
Compatibility
Product A supports Windows 11, 10, ChromeOS 100+, and macOS 14+ with manual DisplayLink driver installation. It is not compatible with Linux. Product B is designed for Windows 10+, USB4, and Chromebook systems with DP Alt Mode. It is not recommended for macOS for dual extended displays. Product A offers broader operating system support, including older macOS versions via drivers. Product B is simpler for Windows and ChromeOS users who want plug-and-play functionality without driver management.
Physical Build
Product B is lighter at 8.1 ounces but larger in footprint, measuring 9.25 inches in length. Product A is heavier at 13 ounces but more compact, measuring 6.45 inches in length. Both are black. Product B’s lighter weight may benefit portability if you move the dock frequently. Product A’s smaller footprint might fit better in tight spaces. The size difference is noticeable, so measure your desk space. Both units are designed for stationary desk use rather than frequent travel.
Which dock fits your specific setup needs
Users needing 4K resolution and driver-free setup
Choose this dock if you require dual 4K displays at 60Hz. It offers true plug-and-play operation without installing any drivers on supported Windows or ChromeOS systems. The host interface relies on USB-C with DisplayPort Alt Mode. You get higher clarity for detailed work, provided your laptop supports this specific video output capability.
Windows users with standard USB 3.0 ports
Select this model if your laptop only has USB 3.0 or USB-C ports that do not support video output. It uses DisplayLink drivers for Windows 11 and 10. It supports dual HD monitors at 1920x1200 or a single display up to 2560x1440. It also works with ChromeOS 100 or later without extra setup.
Mac users needing basic single monitor extension
If you use macOS 14 or later, this dock allows you to add an external display via a manual DisplayLink driver installation. The other dock is not recommended for Mac users who need dual extended displays. This option provides a functional, albeit limited, solution for extending your desktop on Apple systems using standard USB connectivity.
Users needing host laptop charging capability
This dock includes an 110W power adapter to support your workflow, though it primarily focuses on display and peripheral connectivity. The other dock explicitly does not charge the host laptop. If you need a single cable solution for peripherals and video without worrying about power delivery to your computer, this model provides the necessary hardware support.
