Your needs, this model
Does it fit your priorities?
Will it run two 1440p 60 DisplayPort screens on Windows?
Yes, with a suitable video-capable MST host. The exact model table documents two 2560×1440 screens at 60Hz.
Explore this need in the finder →Can an Intel Mac get two independent desktops through it?
No. The maker says a second external monitor mirrors the first on Mac, so two independent external screens do not fit.
Explore this need in the finder →Can I use passive DisplayPort-to-HDMI cables for my two HDMI monitors?
The maker requires active conversion, and the hub itself supplies DisplayPort sockets. A requirement for two native supplied HDMI outputs excludes it.

The Cable Matters 201055 is a USB-C travel hub for a pair of DisplayPort monitors, alongside two USB 2.0 accessories, wired Ethernet and laptop charging. Its most useful arrangement is a suitable Windows or Linux computer that supports DisplayPort MST. The screen connectors, computer capability and simultaneous video mode all matter.
This is not a universal two-monitor dock for every laptop. On Mac, a second connected external monitor can mirror the first, but does not create a second independent desktop through this MST arrangement. If two separate Mac workspaces are essential, choose a different specifically documented setup.
Two 4K30 screens or two 1440p 60 screens
The manufacturer table is explicit about the simultaneous modes. It supports two 3840×2160 displays at 30Hz, two 2560×1440 displays at 60Hz, or two 1920×1080 displays at 60Hz. With only one screen connected, the documented 4K ceiling becomes 60Hz.
That makes the 201055 a reasonable candidate for two 1440p office monitors. It is a different proposition for a buyer who wants two 4K60 screens: the higher single-display figure does not carry over to two screens. Compare the actual simultaneous table rather than multiplying the single-output maximum by the number of sockets.
The original support article also explains a common setup problem. If the first 4K screen automatically takes a 60Hz mode, there may not be enough remaining bandwidth for the second. It suggests lowering the first screen to 30Hz before configuring the second 4K30 display. This is manufacturer troubleshooting guidance, not a performance test of our own.
DisplayPort conversion needs an active adapter
The native outputs are DisplayPort. Cable Matters says an active converter is required when connecting HDMI, DVI or VGA displays; passive adapters or cables do not provide the required conversion. Those converters are additional accessories, not native HDMI sockets built into the hub.
If both monitors already have DisplayPort inputs, the direct connection is simpler. If your desk is entirely HDMI, compare the cost and complexity of active converters with a hub that provides the required HDMI arrangement directly. The 201056 dual-HDMI model is a separate product with its own documented configuration limits.
The computer's video path is part of the purchase
The USB-C host must provide DisplayPort Alt Mode for native video. The manufacturer also lists supported Thunderbolt and USB 4 connections, but a USB-C port carrying only data cannot supply the screen function. Windows 10 and Linux are the documented dual-screen context.
The current FAQ confirms ordinary single-monitor Mac operation, while explaining that two external monitors mirror. The older support article also notes that a 12-inch MacBook may itself be limited to 4K30. A general Mac compatibility statement therefore does not guarantee the maximum output on every computer model.
Useful charging, limited accessory speed
The detailed manufacturer body and model-specific support article state up to 60 W passed to the computer using a suitable external PD charger and cable. One current FAQ answer says 100 W, conflicting with those more specific 60 W instructions. We retain the documented 60 W arrangement rather than promising an unverified 100 W laptop budget.
Both USB-A accessory sockets are USB 2.0, with advertised rates up to 480 Mbps. The network connection is 100 Mbps Fast Ethernet, not Gigabit. This is a sensible combination for a keyboard/mouse receiver and wired office access, but not for fast USB storage or a Gigabit network requirement.
The 6-inch attached tail wraps into a removable protective case. Choose the 201055 when its exact dual-DisplayPort Windows/Linux arrangement fits the desk. Choose differently for Mac dual extension, native HDMI outputs, faster data or a higher verified charging requirement. Its value lies in a complete supported setup, rather than a general count of display sockets.
