KensingtonSD4780P Displaylink USB-C Docking Station for Windows, MacBooks ane Surface – Dual 4K Video, 100W PD (K33620NA)

We use this dock with a few Dell systems including the Latitude 5591, Latitude 5520 and Precision 3551. It supports two screens natively but we also purchase the Kensington USB to HDMI adapter to add a third screen. We connect the HDMI/USB adapter directly to one of the USB ports on the dock and it works perfectly fine; though note that this is not a recommended scenario by their support team. We're using office applications like Excel, and video calling like Microsoft Teams and this equipment handles it perfectly whether it's in USB-C mode or in the optional USB-A mode offered by the adapter on the docking cable.I have significant bias to Kensington because their docks are reliable and easy to setup for use. Our company has been through dozens of similar Kensington docks including the SD4700P and SD4750P and this one works just as well but is the newer higher spec'd one. We've purchased about fifteen of this one in particular. The main difference is that this one, the SD4780P, can deliver more charge to the laptop while it's in use. This one delivers 100w PowerDelivery which was a lot more necessary for the power requirements of our Precision models. (As opposed to the other older models which deliver something like 65 to 80 watts.)Note that some of our laptops have turned out to be finicky and showed issues when using the USB-C docking port. This leads to things like strange Windows messages about charging speed, USB devices malfunctioning, or flashing screens. In almost every case, it's been due to a USB-C malfunction on our brand new Dell Latitudes. They're covered under warranty so Dell comes out to replace the motherboards and then everything works just like it should. If you find similar problems your USB-C port may have an issue.In a few cases the dock itself has been at fault but Kensington customer support has always been very responsive and make it right.This dock may not cut it if you need to use the bleeding edge high-spec features in expensive monitors for graphic-intense scenarios. If that's what you need I seriously suggest a desktop computer with dedicated graphics card. Good luck finding a docking station that actually does all that without breaking the bank. For us, this is the perfect flexible dock for fulltime staff and hotdesking users alike.

This dock claims to push dual displays via “display link”, though it fails to mention broadly that you need to download a driver to make that happen. That is annoying, but fine. The bigger problem is that this driver requires screen recording permissions to be able to detect displays for some reason. I cannot get it to detect either hdmi or DisplayPort displays with it turned off, and there’s no way I’m enabling screen recording for a random driver I downloaded from the internet.Finally, the product name says it’s a thunderbolt dock, but that just a plain lie. It’s strictly usb c, and thunderbolt happens to be compatible with usb c, but this is not a thunderbolt dock.Absolutely disappointed with Kensington on this one. I have a couple of their iPad products and they’ve been great.

This dock was great it works with my Macs and my Windows laptops. It drives my 4k monitor and another 1080P monitor, plus the laptop monitor. It has enough ports for all my peripherals. And provides plenty of power to charge the laptops.There was an issue with flickering, but if you go to the support website and download the DisplayLink driver for the Windows computer, it works flawlessly. It may be only some computers, but my computer benefited from this driver, and now I have no issues.Great product!

The unit is good. Works well with 2 monitors while charging the laptop and able to support multiple USB devices at the same time.The things I don’t like about the unit is that it’s relatively big, and that most USB ports are at the back of unit. There’s only one USB port at the front. So when you want to insert 2 external disks, you’d have to flip the unit around and hook up one at the back. This doesn’t really deliver the expected conveniences I’m looking for.But since it’s working so far compared to other stations I’ve tried before, I give it a 4 star

I was worried about purchasing a docking station / port replicator with a 3.8 star rating, but Kensington is a know quality brand name and so I took a chance. I'm well aware that most of the port replicator market seems to have rather low scores and they all seem to be a guess in the dark at best as to if they'll work for you or not.For this device I got it with the mount and I love them both. I am switching from an Anker port replicator which was always a bit fickle. The Kensington device is fantastic and I haven't had an issue with it at all. It was easy to setup and has been working well for me. It's not as hot as my previous port replicator and it has more USB ports available on it allowing me to free up a USB hub.Great device and the overall rating does not match the quality of the device. This is a 5 star device in my opinion.

Albeit, I should've managed them. This is a DisplayLink dock (not a driverless one) which I didn't know at the time of purchasing. I should've, though, as it's Hybrid. I don't blame Kensington for this.What I do blame them for is for the performance of this dock. I know it isn't primarily meant for gaming, but when I'm running two 1080p displays at 75Hz, and my keyboard keeps disconnecting for some reason, then there's a problem. Plus, the performance hitch from using DisplayLink was very noticeable, especially when gaming. My CPU was slammed with work from the DisplayLink driver.I was going wait for a Thunderbolt 3 Cable to see if this would alleviate the situation, but after trying out my old 60w Thinkpad Dock and seeing better performance, I think I'll just stick with that for now.
