Kensington SD5800T Thunderbolt 4 and USB4 Quad 4K Display Docking Station, 100W Charging, 2 x HDMI, 2 x DP, 2.5G Ethernet, Card Readers, for Windows/MacOS (K32856NA)

I had a problem with one of my monitors turning on and off. I changed monitors and cables without making a difference. I contacted Kensington support, and they replaced the dock 11 months after purchase.Good product, better customer service.

This is a horrible docking station.Monitors randomly turn on and off, mouse, keyboard, and headphones randomly stop working, other times the whole thing just decides it does not want to work, so you have to reboot your whole computer, and even then it does not come back and you have to keep rebooting your PC.

I just set this up to connect to dual Dell 1440p, 27" monitors. One is connected to the dock with a display port cable, the other with HDMI. Also plugged in is a USB A keyboard, wireless mouse, and direct Ethernet cable.When I connected my (approx '22-'23) Windows Dell Latitude laptop to it via the included USB-C/TB4 cable, it worked without issue right away. Then came time to test a Macbook Pro with M1 Pro Chip (2021). Initially, the monitors acted like it got a signal, but there was nothing showing up on them and they eventually went to sleep. I went into the display options and saw the the Macbook had recognized the monitor. I had to switch the refresh rate down to 60 HZ. Then both monitors turned on, but were mirroring each other (effectively I had an A-B-B monitor setup instead of the claimed A-B-C, where A is the laptop, and the other two are extension monitors).After searching, asking chatGPT, etc... I had almost given up, when I decided to search for the previous model (5700) after doing a more broad search about Kensington and Apple products, and luckily came across a reddit post. They indicated they had a similar problem, and that Kensington support told them they needed to unplug everything, the plug back in in the following order: 1. Power 2. USB C to computer 3. Displays and other peripherals. As soon as I did that it worked and behaved as "A-B-C" extensions. Yay! The poster indicated that did something with bandwidth prioritization within the dock.In any case, it worked. I then unplugged my Macbook, then retried the Windows, then back to the Macbook and the screen extension settings worked as they had been, no need to reset.So ultimately I'd give this a 4.5 stars for that (based on the reddit post, this has been a known issue since the previous version of the product in 2023, writing this at the end of 2024), but because it doesn't require any other software to run (it is "natively compatible" as the documentation states), I'm happy and will round up to a 5.

I am very disappointed but don't want to give less than 4 stars because I don't know if the dock is causing the issue or if it is something else.I have three Dell U2723QE monitors connected to this dock with USB C and only two will work at a time. I've tried using USB C to Thunderbolt cables on all three instead and it is the same result. I tried Kensington support and Apple support and neither of them could give me any ideas that worked. The screens are 4k 60hz but they still don't work at lower settings.The only way I am able to get my three screens to work with this dock and the MacBook Pro M4 Max is to have one of the screens plugged directly into the Mac. Somewhat defeats the purpose of the dock and I could have done that with one that costs half as much.I'm hoping a firmware update or something comes out to resolve this issue but for now it is about a 3 star product. I just didn't want to do that and then forget to change the review if they resolve this issue, so I'm going with 4 for now.If you have a solution for my issue, please let me know.

I used to worry that using any charger for my macbook that was not an Apple charger would ruin the battery.So far so good. And this has cleared up a ton of space and cables on my desk. If only I can get rid of the rest of the junk on it now lol

Pro's:1) I had zero issues in setting up the docking station for my Macbook Pro M4 MAX and my 2 6k displays. Set up was a breeze and my equipment fired up immediately. No drivers or firmware to install.2) Set up included 2g speed via ethernet cable. All good, no drops. Ditto with wifi speeds at same speeds.3) I had none of the drops or disconnects that others were referring to. Doc worked beautifully.4) Docking station is well built, sturdy & premium device.5) SD Card reader worked with no issues.Other Considerations:1) The host port to connect docking station to laptop is built in the front of the docking station. So you have cables running from front and back of the device. (The back includes 2 USB-C ports/cables to 2 displays and 1 power cord + 1 ethernet cable). So I either have to leave the docking station octopus mess on top of my desk or buy longer cables and place it on the floor (which offers no easy access to SD Card Reader) - - both not exciting options. For $390 plus tax, I would have expected a cleaner cable design for users.2) There is no CFexpress Card Type B Card reader.3) You may need to factor in the cost of two or three USB-C Thunderbolt 5 cables which depending on length can range from $27-$70 each. (Product comes with one 3 meter cable)
