Plugable vs CalDigit Dock Comparison
Display resolution
The Plugable dock supports dual HDMI monitors at a maximum resolution of 1920x1200 at 60Hz. A single display can reach 2560x1440 at 50Hz, but it does not support 4K output. In contrast, the CalDigit TS5 offers significantly higher resolution capabilities. It supports dual 6K displays at 60Hz on macOS, or dual 8K at 60Hz on compatible Macs. Windows users with Thunderbolt 5 hosts can achieve dual 8K at 60Hz or even triple 4K at 144Hz. The CalDigit TS5 clearly provides superior resolution options for high-density displays.
Connectivity ports
The Plugable dock provides a hybrid USB 3.0 and USB-C connection, offering two HDMI outputs, gigabit Ethernet, audio jacks, two USB 3.0 ports, and four USB 2.0 ports. The CalDigit TS5 is a more comprehensive hub with fifteen ports. It includes three Thunderbolt 5/USB4 V2 ports, one USB-A Gen 2, one USB-A legacy port, three USB-C 3.2 ports, DisplayPort 2.1, SD and microSD card readers, 2.5GbE, and three audio ports. The CalDigit TS5 offers far more physical connections for peripherals and storage.
Power delivery
The Plugable docking station does not charge the host laptop. It relies entirely on the computer's internal battery or its own power adapter for operation. The CalDigit TS5 includes a 240W power supply and provides up to 140W of power delivery through its host charging port. This makes it suitable for power-hungry laptops, including 16-inch MacBook Pro models. Additionally, one front USB-C port on the CalDigit TS5 offers up to 20W for charging accessories. The CalDigit TS5 is the only option that charges your computer.
Ethernet speed
The Plugable dock features a standard Gigabit Ethernet port, which supports network speeds up to 1Gb/s. The CalDigit TS5 integrates a PCIe-based 2.5GbE port. This is 2.5 times faster than traditional 1GbE connections, allowing for quicker file transfers and better performance in fast network workflows. The 2.5GbE port on the CalDigit TS5 is backwards compatible with 1GbE networks. For users requiring high-speed wired connectivity, the CalDigit TS5 provides a clear advantage in network throughput.
Compatibility
The Plugable dock works with Windows 11 and 10 via plug-and-play drivers, ChromeOS 100+, and macOS 14+ with manual DisplayLink driver installation. It is not compatible with Linux or Unix systems. The CalDigit TS5 requires a Thunderbolt 5 or USB4 v2 host for maximum performance, though it functions with Thunderbolt 3, 4, and other USB-C hosts at reduced speeds. It supports Thunderbolt and USB-C tablets and phones. The Plugable dock offers broader operating system support, including ChromeOS without extra setup.
Which docking station fits your workflow
Windows users needing basic dual monitors
The Plugable UD-3900 connects via USB 3.0 or USB-C, making it compatible with standard Windows 11 and 10 systems without complex setup. It provides two HDMI outputs for dual displays up to 1920x1200. This model is ideal if you only need wired Gigabit Ethernet and basic USB ports for productivity tasks.
Mac users requiring high-resolution displays
The CalDigit TS5 supports dual 6K or 8K displays on macOS, leveraging Thunderbolt 5 bandwidth. It delivers 140W of power to charge high-end MacBook Pros. If you need DisplayPort 2.1 outputs and high-refresh-rate performance for creative work, this dock offers the necessary video capabilities and sustained power delivery for your setup.
Professionals needing fast network speeds
The CalDigit TS5 includes a PCIe-based 2.5GbE port, which is significantly faster than the standard Gigabit Ethernet found on the Plugable dock. This allows for quicker file transfers and better integration into high-speed office networks. The TS5 also provides 15 downstream ports, offering extensive connectivity for multiple peripherals and storage devices.
