Cable Matters 201046 DisplayPort multiport adapter review

Choose it for the DisplayPort connection first

The Cable Matters 201046 gives a video-capable USB-C computer one DisplayPort output, two USB 2.0 accessory sockets, wired Ethernet and an optional USB-C charging input. Its emphasis is the monitor connection. This is a different compromise from a travel dock that prioritizes fast external storage or several display sockets.

The current manufacturer page identifies product 201046, while the currently served original quick-start sheet is labeled 201046_V. Historical listings may use older resolution or charging language. Check the actual edition and host requirements rather than assuming that every historical seller suffix describes the current documented configuration.

High-resolution video depends on the entire graphics path

The manufacturer describes DisplayPort 1.4 support for 8K at 30Hz or 4K at 120Hz. It then separates higher 8K60 and 4K240 modes that require Display Stream Compression 1.2. Those are conditional capabilities of a suitable source, cable and display arrangement, not results automatically provided by any USB-C socket.

For an ordinary 4K60 DisplayPort monitor, the documented capability can be useful, provided the computer supplies the required video signal. For the higher advertised modes, check the graphics hardware, DisplayPort capabilities and DSC support explicitly. A Thunderbolt or USB 4 label does not by itself confirm every maximum mode in every computer.

The adapter has one DisplayPort output. It does not become a dual-independent-display dock because it has multiple other connectors. HDMI and downstream USB-C video outputs are absent from this reviewed arrangement, so match the monitor's actual connector before choosing it.

USB 2.0 is an intentional limit

Both downstream USB-A sockets are specified as USB 2.0, with advertised data rates up to 480 Mbps. They are appropriate connection points for ordinary lower-bandwidth accessories, but they do not meet a 5 Gbps USB 3.0 storage requirement. The maker also says these ports do not support smartphone charging.

The distinction is especially important because the video headline is much faster than the accessory data function. An 8K display claim is not evidence that a USB drive can use a newer USB speed class. Display transport and ordinary USB data have separate roles in this adapter.

There is no downstream USB-C data socket or built-in card reader. The additional USB-C socket is used for charging input, not another general-purpose accessory connection.

Wired networking without a Gigabit promise

The manufacturer expressly answers that the Ethernet function is not Gigabit. Its page and current quick-start sheet describe a 480 Mbps Ethernet figure, using wording that does not establish a standard exact Ethernet link rate separately from the USB 2.0 path. We do not relabel that as 1 Gbps networking.

If your requirement is specifically a verified network link rate, choose a model with that exact standard documented. If the aim is simply a wired alternative to Wi-Fi alongside a DisplayPort monitor, this connection may still be relevant. Your actual network equipment and connection remain part of the setup.

Charging and installation

USB-C pass-through computer charging is supported with a suitable external charger and cable. The manufacturer advertises up to 100 W PD, but that should not be read as an included 100 W source or a verified net power budget available to every laptop. Supply the appropriate charger yourself and leave room for the dock's operating needs.

The reviewed manufacturer page names Windows, macOS, Linux and ChromeOS and describes plug-and-play operation. It also recommends current Thunderbolt drivers where relevant. An optional Windows MAC-address cloning utility is a separate management feature, rather than a requirement that turns every ordinary setup into a software installation.

Choose the 201046 when one supported DisplayPort screen is the priority and USB 2.0 peripherals are sufficient. Choose differently for Gigabit Ethernet, fast USB storage, several independent monitors or an explicitly verified numerical laptop-power minimum. Its usefulness comes from the exact video-centered arrangement, with the accessory limits made clear before purchase.
