Kensington MD120U4 USB4 Hub, Dual Display 4K @120hz, Single 8K @60hz, HDMI, 100W Power Pass Through, 2.5Gbps Ethernet, 10Gbps USB-A, for Mac and Windows (K32850WW)

I’ve been a fan of Kensington hubs, docks, and mice for years. This is another win for Kensington. This hub requires no external power and gives me access to 4k at 60hz on two monitors. It’s portable and I love it. I haven’t been able to find another USB-4 hub with two HDMI 2.1s that support the features that this product does. This is the only “non” Thunderbolt dock/hub I’ve used that works flawlessly. I’ve had no issues with this hub and I’m impressed at how such a small device doesn’t warm up when connected to multiple 4k monitors. Make sure your computer supports USB-4 and definitely try this hub or another USB-4 hub!!

I bought the cable matters 201310-BLK at the same time as this to compare them. But they are hardly even comparable.The cable matters excels in everything even though this one claims to have higher specs. This one claims to be capable of outputting 4k120hz on two separate HDMI 2.1 ports but I couldn't even get it working on one with a plethora of devices. Here are the most notable ones I tried:-SteamDeck - Capped at 4k60hz-Gaming laptop with USB4 and dp1.4 alt mode - Shows 4k120hz as an option but flickers at all resolutions and all refresh rates. Unusable at any setting.-M1 Macbook - Doesn't work at all.Compared to the cable matters dock which does 4k120hz on steam deck & gaming laptop plus works at 4k60hz on the Macbook Its laughable that this docks price is over double and claims to be able to do 2 HDMI ports when it cant even do one. I was skeptical about this capability given the 40gbps bandwidth of usb4 which is barely enough to handle one HDMI 2.1 link let alone two. Its also larger/heavier and less pack-able.The USB ports also claim to be 10gbps on this compared to the 5gbps on the cable matters dock. But once again it didn't perform to spec on a single device. The cable matters could let my USB drive transfer at full 200MB/s write speed. On this dock it was basically throttled to nothing as you can see by the picture. It was so slow Windows To Go on USB was slower than an install on a cheap SD card for the docked Deck.

2.5 Gb Ethernet is awesome. It works great with my M2 Mac Book Air

Sadly its very unreliable, sometimes it works, other times I hace to restart for it to works.First time, I had to uninstall and reinstall my intel graphics driver, inconvinent. It worked find after that and now again its hard to get it working, even though Im only using one hdmi outpout, using it as an adapter from type c to HDMI, not worth it.Very likely will return, as it's not stable.My setup:Asus ROG Strix laptopAsus HDMI outpout to LG C1 TV.From Asus Type C to this device HDMI to Benq monitor(Using Original PS5 HDMI 2.1).Cant get it to work smothly, specially with graphics updates it seems to stop.

I use it with Mac M2 Max. I'm only able to connect one 4k 60 HZ monitor. If I connect two monitors only 1 of them works. 120 HZ does not work even for 1 monitor. USB connections are not always recognized (e.g. webcam), although a cheap hub (~4$) handles it well.

Using Samsung Galaxy Tab S7+, I was able to plug in a power source and charge the table while playing music from a USB thumb drive.Sharing data files from thumb drive worked well.

Used it for 2 monitors (3800 x 1600 @ 120 HZ and 1080P @60 HZ ), 1 ethernet cable, and 2 USBs. However, I need to remove 1 and 2 cables because it cannot handle my needs. The internet drops and screen resolution decreases every time I log off my laptop. I like the products and its small size, but it is not strong enough for my PC performance needs.

"Macbook Pros with M1 Pro , M1 Max, M2 Pro & M2 Max CPUs will work with dual extended displays; however MacBooks with Apple's M1 or M2 processors will only display to a single monitor due to Apple’s chipset limitations (see our SD4780P dock (part #K33620NA) for dual 4K display for those models"This is not correct. Manufacture website says it only supports 1 external display for macbook.
