CalDigit TS3 Thunderbolt 3 Docking Station with 0.5 meter cable - 85W Charging. USB 3.1, eSATA, DisplayPort, LAN, Audio for 2016/2017 Macbook Pro and Windows PC

This docking station appears well made and supports two 4K monitors at 60Hz using display port and T/B-DP connector and provides ethernet ports and multiple USB and eSATA connections..The main issues arise due to the type of docking station it is (and therefore most of the following comments are likely to apply to any make.Since it connects by T/B over USB C, when my laptop "wakes" from hibernation or sleep, it then goes through a process of recognising what is plugged in. This means that the laptop display is identified first, which moves any programs open to that screen, then it identifies each of the two connected external monitors and then moves anything open onto the one selected as "primary" display. This means that each time the laptop is woken up, anything was was placed on different screens are now all on the same one and need to be manually moved back. No a big issue but frustrating because it happens every time. Sometimes, one monitor does not go to sleep when the laptop sleeps, sometimes one doesn't wake up. I did contact CalDigit about this but did not get any helpful response. Also, I use the ethernet port on the docking station, so when my laptop awakes it fires up the Wifi, until it discovers the ethernet port and then switches, which can sometimes cause an issue. Naturally, everything is sharing the same bandwidth as the T/B USB connector, which although has a high bandwidth, much of it is consumed by driving 2 4K monitors at 60Hz and 32-bit colour. Also to diver two monitors, since it only has 1 display port, you need to use the only other T/B USB output with a conversion cable (T/B USB C to DP), this means that any further use of T/B over USB will require an additional splitter. So you can up with a number of adapters and splitters which can make it look like a bit of a kluge.On the plus side, since it connects via a T/B using USB C, it should work with pretty much any laptop and so could be useful if different machines are used in a single location.Previously I have used Thinkpads with a dedicated Thinkpad base, where each of the monitors are connected directly via displayport, and the laptop uses a dedicated docking port (underneath) rather than a USB type connector. In this configuration, everything works perfectly all the time with none of the dicovery over USB issues.

OK. So I bought this for my touchbar macbook 2017 pro like everyone else seems to have done. At first things worked fine. An Asus 1080p monitor via DP- to DVI adaptor then DVI to DVI cable worked fine. Also a LG 1080p USB-C to DVI cable worked fine. Both monitors would connect from sleep and switch off from sleep.Then I upgraded the Asus 1080p monitor to an LG 4K monitor and things started going down the pan. The new 4k monitor had a DP connection and I connected it via the supplied DP-DP cable to the DP port on the hub. New monitor 4k wouldn't connect from sleep at times, it wouldn't power off at sleep or would switch on automatically when everything was off.I went to the Caldigit website and emailed them- no reply. Website said that DP connections can be the most unreliable suggesting replacing the cables or HDMI.I then bought a new DP-DP cable- refresh frequency increased to 60hz at 4k but then monitor still wouldn't switch on and off during laptop sleep. You'd also lose the connection from time to time thus requiring a full restart. I deleted monitor preferences app and things improved a bit- 4k monitor would then switch on more consistently with correct resolutions.However then the 1080p monitor which was connected via USB-C to DVI wouldn't switch on after sleep. You could take it and connect that to the MBP and it would work fine.It's now working but weirdly enough: 4k monitor being driven by USB-C to HDMI adaptor via HDMI cableAsus 1080p monitor being driven by displayport to DVI cable- https://www.amazon.co.uk/gp/product/B01KANYY8U/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1It's a bit temperamental and very very dependent on finding the correct cables and monitors. If only Caldigit would have a page on their website with recommended tested cables which they know would definitely work with which monitors- I would have saved about 5 hours of tinkering. So far I've spent £75 on different cable combinations

I bought this device as it was advertised as an Apple and PC docking station. My Asus only has 1 Thunderbolt 3 port and I thought this would be ideal for expansion. At over £200 I thought it would just be a matter of plugging it in!!! Then the problems started. After connecting the device my computer would freeze up and I would need to restart it. I contacted Caldigit who said they would contact their tech department. After 4 days I got the reply "We have heard from our support team in the US & they have confirmed that the TS3 has never been tested with your type of device. They do not believe there is a fault with the unit but a compatibility issue with your type of device.We do not believe there is an easy fix for this so you may wish to return the issue to Amazon.Sorry we were not able to offer more assistance".For a device advertised as PC compatible and £200 I find this totally unacceptable!!! Using my own experience I found a way to get the device working hence the 2 star rate. It takes a bit of messing around in device manger in windows but I can manage to get it working. I would not recommend this device unless you have confirmed that caldigit have tested the device with you type of computer and is compatible. Caldigit were friendly enough however passing the "issue" to amazon is not the reply I would have expected as this is a Caldigit product not Amazon!!
