Since the X1 Extreme / P1 / P52 / P72 need more than 100W to charge when fully loaded, there is no question which dock to buy for those if single plug docking is a requirement. By default two lanes are used for USB data, one for transmitting at 10gbit/s the other receiving at this speed. The latest version of Safari, Chrome, Firefox, Internet Explorer or Microsoft Edge is required to use this website. It's a bit too expensive for what it is. If one digital output is requested, it gets the full DP signal there and the half signal into the VGA. Either avoid completely or make sure you are buying from a vendor with a good return policy. The "ThinkPad Pro Docking Station" 40AH uses quite the trick to solve the USB C bandwidth problems: it uses two USB C connectors. Corporate bulk purchasers don't usually go for it. This docking station is fully functional. This is a TB4 dock with an MST hub providing quad display capability. The Ethernet port can either be 2.5gbps using an Intel i225 or when connected to non-Thunderbolt systems, an 1GbE Realtek 8153 is also present. Explore our high quality used equipment from top brands at a fraction of the cost of buying new. Finally, if three digital outputs are requested then the full one goes through and the half signal is ran through the MST hub. Seller assumes all responsibility for this listing. The Workstation Dock ships with a 170W or a 230W adapter and a special cable: two plugs (one power, one USB Type C) in a plastic shell so you need to plug one cable. Before going into the USB C jungle, quick refresh on what USB C is and what can happen in there. The physical connector has four high speed lanes. This and every later dock support USB C only hosts even if TB3 is not available.

This. These can not support two 4K @60Hz monitors or similar video bandwidth needs from a single cable, Thunderbolt or not. This typically meant various X1 and P1 laptops. However, almost all non-powered dock/adapter will not re-negotiate power delivery rather it'll just decrease the nominal voltage slightly which stays within the PD standard allowed zone -- but to do this, it needs to take the losses of the USB C cable into account and that's why these have a very short captive cable. When trying to use two laptops with a single keyboard/mouse look at https://github.com/haimgel/display-switch/ first. If two digital outputs are requested, the full DP signal is ran through MST hub and the half signal is still going into the VGA. Most of the time, a much cheaper USB C dock or a competitors TB 3 dock is a better bang for the buck. Here's the capability list: The USB standards allow USB C to deliver up to 100W to power an attached device, but typically such a high wattage charger isn't needed: most ThinkPads capable of charging from USB C at this time (and very likely the future given trends) are fine with just 45W and will slow charge with less. DisplayPort 1.3 raises the available bandwidth from 17.28gbit/s to 25.92gbit/s and DisplayPort 1.4 adds Display Stream Compression (DSC), a "visually lossless" compression which aims to triple the bandwidth. The "Dock Gen 2" ships with a 135W adapter without the special cable and charges the connected laptop over Thunderbolt. It's not known what "smart" means here compared to the 40B0. The P52 and later P laptops have full implementations and support DisplayPort 1.4. It supports two monitors using DisplayPort 1.4, there's no MST hub. {"modules":["unloadOptimization","bandwidthDetection"],"unloadOptimization":{"browsers":{"Firefox":true,"Chrome":true}},"bandwidthDetection":{"url":"https://ir.ebaystatic.com/cr/v/c1/thirtysevens.jpg","maxViews":4,"imgSize":37,"expiry":300000,"timeout":250}}. Even current laptop models that ship with slim tip power adapters (P52/72/1 and X1 Extreme) and generally consume more than 100w peak and thus cannot be fully powered via USB PD are capable of running and charging the battery at a reduced rate with USB C power adapters but these might require 100W -- the X1E4 does, for example. DisplayPort has a feature called MST where the MST hub takes a DisplayPort signal and drives multiple monitors from it.

This setup is not confirmed but this explanation is the only one I can figure out fitting the resolution table published by Lenovo. In practice this means USB 3.0 and dual 4K @ 60Hz is possible with a relatively cheap USB C dock if the host is capable of doing DP 1.4 and DSC at the same time. The "ThinkPad Ultra Docking Station" 40AJ marries "40A9" with "40AH": it takes two USB C connectors and uses one in DisplayPort alt mode and one in mixed mode -- so dual 4K @ 60 Hz is not possible. Not only does it fit the resolutions supported but tells you why other ones are not in the table as well. The only tools you need for servicing a ThinkPad are a set of small screwdrivers and a nylon spudger (for taking the screen and keyboard bezels off), and possibly a pair of tweezers. The "ThinkPad USB-C Dock" 40A9 is a mixed mode USB C dock daisy-chained to an MST hub so it can drive two 1080p @ 60 Hz and 5 gbps USB ports. Intel ThinkPads with two TB3 capable USB C ports are full implementation and so are the P50/P51 (these two are an exception to #1). Press question mark to learn the rest of the keyboard shortcuts, complete list of all Lenovo docking stations, https://dancharblog.wordpress.com/2021/02/05/usb4-tb4-docks/, https://github.com/haimgel/display-switch/, Lenovo Parts Removal and Replacement Videos, This low power version was used on all Intel ThinkPads with a single TB3 capable USB C port: the T470-T14 Gen1 and similar generation X2/X3 laptops. The TB4 bus now carries USB signals as well, greatly increasing the reliability of USB devices connected to the Thunderbolt bus. It can't conjure more bandwidth than available so if you feed a DP 1.2 full signal into it then you can drive four 1080p monitors, two 3440 x 1440 @ 60 Hz, or even a 4K @ 60 Hz + one 1080p. Thunderbolt 3 in theory could carry two full DisplayPort signals and 32gbps data flexibly with a 40gbps total limit. Thunderbolt 3 was an Intel proprietary bus which carried DisplayPort and PCI Express. Then Intel handed it over to the USB IF which turned it into USB4. Below is some deep-dive information, as well as some info on specifics. Copyright 1995-2022 eBay Inc. All Rights Reserved. TB4 and USB4 are equal for all intents and purposes (TB4 is an Intel marketing term for full featured USB4 and Microsoft made it mandatory for USB4 to be full featured). Never use acetone (nail polish remover). TB4 docks will pass video to their first downstream port even if the host is not TB capable. It is also possible to use only two high speed lanes and then 10gbps USB data speeds are possible over the last two lanes. However, there was a cheaper/lower power TB3 controller called which only put one DP 1.2 on the bus and allowed for 16gbps data total. It may feature very light scuff marks and scratches. Especially bad purchase for the X2/T laptops because their half Thunderbolt matched with this dock has zero advantage whatsoever over the dual USB C Pro/Ultra docking stations. Lenovo docks using this technology include "40AA", "40A7", "40A8" and the Hybrid dock "40AF". Create an account to follow your favorite communities and start taking part in conversations. At the time of this writing, Intel chips seems to have a problem with this, see this post. Lenovo provides a complete list of all Lenovo docking stations. Thunderbolt 3 here is only useful for two use cases: 1) when external PCIe is needed for eGPU / 10GbE / TB3 SSD 2) when the aggregate video bandwidth needs exceed half a DisplayPort 1.2 and USB 2.0 is not enough. In fact, if the Ultra explanation above is correct then the Ultra provides more video bandwidth than this one. - Top Rated Plus - opens in a new window or tab, - eBay Money Back Guarantee - opens in a new window or tab, - for PayPal Credit, opens in a new window or tab, Learn more about earning points with eBay Mastercard, - eBay Return policy - opens in a new tab or window, - eBay Money Back Guarantee - opens in a new tab or window.
