Cable Matters 8-in-1 Portable 40Gbps USB4 Hub (USB 4 Dock) Dual DisplayPort 4K@60Hz, Single DP 4K@240Hz/8K@60Hz, 100W PD, Gigabit Ethernet, Compatible with Thunderbolt 4 (*macOS's Display Limitation)

I don't really need a USB4 dock. I have USB 3.1 Gen 2 ports. I don't do heavy gaming or large file transfers to external drives. My displays are wide screen so the resolution is 3440x1440 instead of 4k. So why did I get this dock?I own several other devices from Cable Matters. I have a USB-C KVM so that I can switch from my work computer to my personal computer. I have a USB A to HDMI adapter so that my Mac (for work) can run 3 separate screens. I have their cables. Finally, I have some of their older docks that I use around the house for docking my Steam Deck or a laptop to each of my TVs. Cable Matters has always been super responsive and helpful when I've contacted them. So when I went searching I immediately looked at their products.They're coming in at half the price of competitors for the same specs and better support. It does what I need with my current setup and I have enough faith in them that when I upgrade my laptop in a few years it will still be working. Setup was easy, I get full resolution on both monitors, all my peripherals work with it, and it's not causing me to have to reboot like the cheaper (and much slower) no-name dock I was temporarily using with this setup. It's running as fast as my laptop will let it run and I couldn't be happier with it.

I would recommend. Provides a single cable interface for my laptop with USB 3.2, Ethernet, and DP-ALT 1.4a over USB-C. It is the bridge between my laptop and KVM and it works exactly as I expect it. I don't use it for thunderbolt or USB4. It works great for my purposes.

It just works. No lag, clear video, fast transfer

Failed after just a month of use. Just outside of the return window... No longer provides power. Tested with many different power sources and computers. I was using a high quality 65watt power source that hasn't had issues with any other hubs or docks.Even when it worked, I had frequent issues with usb audio devices. Both Windows and Linux on different laptops so it doesn't seem like software issues.Maybe I just got a dud. Either way, I don't recommend it

Although the port that I got intinially was faulty, the Cable Matters team provided excellent support by sending a new one and walking me through all the troubleshooting steps. Once we realized that my set up was not compatible with this hub they kindly provided a full refund for it. Truly amazing customer care.

I was pretty confused about USB-C (vs USB4 ?) vs Thunderbolt, but I think my Lenovo X1 Carbon laptops (Gen 9 and 10) use Thunderbolt and not USB-C. I was only able to reliably get one external 4k display working at 30 Hz. I could occasionally get 2 external 4k displays working at 30 Hz, but I couldn't reliably reenact the magical incantations necessary for this.It's a nice form factor and and the price is good, but just didn't ultimately work reliably for me.

For the price this is a pretty incredible package. Even including a wall jack usb-c charger, you save money over getting say, a wavlink ugpdxyz, and on top of that you get at least 160hz out of both displayports according to my testing. I haven’t seen any downsides with this thing yet at all

Seeing the specs and reviews, I had very high hopes for this dock. Unfortunately, some of its best features did not work as intended.I have an Alienware m15 r7 with an RTX 3070 Ti GPU and a ASUS ROG 27 inch, 1080p, 165Hz G-Sync compatible monitor. The monitor is connected to the dock via a DisplayPort 1.4 cable, and the dock is plugged into the laptop's Thunderbolt 4 port.Despite being connected to the Thunderbolt 4 port where the laptop's GPU is, the monitor is only able to connect to the laptop's Intel Graphics at 120 Hz with no variable refresh rate. After troubleshooting with Cable Matters, and doing research online, we came to the conclusion that the dock has compatibility issues preventing it from connecting to the GPU.I can confirm it is an issue with the dock, because when I connect my monitor to my laptop directly via a DisplayPort to USB-C cable, it connects to the GPU and outputs 165 Hz at 1080p with variable refresh rate.If 1080p 120Hz is good enough for you, this is a decent dock with a good selection of ports and the 100W pass-through also works well. If you have a gaming laptop and are looking to get the most out of your GPU, you may run into compatibility issues like I did.
