    What makes this a "Windows only" dock?

    • +2

      Came to ask this too. I don’t see why it wouldn’t work on a Mac with the appropriate cables? Anyone else know why?

    • +2

      If it doesn’t require drivers on Windows I’m willing to bet it’s good for Mac/Linux as well

                insane for Apple fanboys to expect a PC company to support them

                If you calm down and look at the original post it does not so much as suggest anything about expecting support.

                The post is about open hardware standards and statements from companies like Lenovo who may have zero intention of supporting hardware on other platforms but produce hardware that will quite readily work on other platforms due to open standards.

                It’s only due it’s being on sale that this is worth considering (if you’re not on Windows). Didn’t neg you either (not even as a favour).

          I got it few weeks ago and i just set it up and off it goes, didn't install any drivers.

        I think it's just because it uses DisplayPort Multi-Stream (MST), which doesn't work properly on macOS.

        • After some checking, based on the firmware update notes, which has the following:

          Fixed the HDCP1.4 authentication issue in MST cascade mode

          So this appears to use MST, so if your laptop does not support MST, do not purchase this. This is why it is called Windows only.

    • +10

      I have this dock, works perfectly fine with both my MacBook Air M1 and Lenovo X1 Carbon G9.

      Don't see any differences in functionality. Only connected to one monitor though (the MBA M1 only supports one monitor anyway), but no issues at all compatibility or performance wise.

          • +5

            @jaypee06: If your USB-C port on your computer doesn't support DisplayPort or Alt-Mode, then you can't use this dock. You would need a dock that uses DisplayLink technology if you have a dumb USB-C port, or get a dock that connects via USB-A (which almost certainly uses DisplayLink)

    † The in-box 90W power adapter charges ThinkPad and other USB-C notebooks up to 65W. For 100W charging, an optional slim tip 135W power adapter is required which is sold separately.

    Also - 2x 4k@60FPS seems ok…

      if 65w then might be a good pair for the ROG Ally in desk mode (or under the tv)…

    For anyone contemplating using this on a work laptop that's at least somewhat locked down by their IT dept., I've got a similar Lenovo Powered USB-C Travel Hub and the Ethernet port requires specific drivers from Lenovo to operate, which obviously my work laptop won't let me install.

    For my hub, I ended up needing to use one of the two USB ports for an USB to Ethernet adapter that uses generic drivers, which partly defeats the intention of using the hub as a one cable solution, but alas. YMMV with this one.

    • Can't you log a ticket with your IT dept to remote in and install the driver? Surely they would allow a Lenovo provided driver if you link to the Lenovo.com download page for it.

      • +8

        In most cases it is easier said than done. Any new driver / software will have to go through a lot of verification, testing and onboarded to the software distribution tool. All these stages required engaging with different teams and approval /exemption with business justification. At least this was the case in my scenario for logi options + which in eventually gave up.

        • +7

          Since this essentially my job I can wholeheartedly confirm that. Additionally, in the past year or so we’ve found that Lenovo are slow to release updated driver packages, which means the official release version they support will most likely be several versions behind the latest version released by component manufacturers. This makes it frustrating when you (inevitably) run into issues that can be solved by a later driver but Lenovo haven’t yet certified it. You either wait for them to eventually get around to releasing a package (if you’re lucky, sometime this decade…) or else run a mish-mash of drivers that have no semblance of common versioning across the fleet. Makes it very hard to recommend their hardware for commercial use, but would be fine for a single home PC where you don’t have to worry as much about stability on a wide scale. /rantover

            @Chazzozz: We have 200x AMD/MediaTek L13s at work. Their drivers are trash with wifi regularly dropping entirely.

            We haven't had many Lenovo issues in the past, but geez, we're 9 months with these devices and just going around in circles.

            • @scphotos: Yikes - we're about to evaluate the T14s G2 AMD as a potential workaround for Intel's V-PRO tax. I'll make sure the team who is running it knows to double-check all networking drivers. Thanks for the heads-up.

              • @Chazzozz: Good luck! Test, test, test.

                We've had Lenovo onsite 5 times and sent 10 devices to them (PS they don't provide any hotswaps so good luck if you don't have some extras)

      • Others have covered off what I would have said pretty thoroughly. A combination of factors means it's just simpler using a generic adapter (which, Lenovo probably could have done but decided to make specific drivers a requirement instead).

  • +3

    Hey @Carushi, please add the model number into the title (40B50090AU). Lenovo has an array of USB-C docks so it can be confusing to know which one this is.

    Also, if you are wondering what screen/Hz combo this one can support: https://support.lenovo.com/au/en/solutions/pd029622-display-…

    It has 2x DP 1.4 + 1x HDMI 2.0.

    Basically, depending on your laptop/PC, up to 2x 3840x2160@60Hz + 1x 3840x2160@30Hz.

    • I think it has 2 x DP 1.2 + 1 HDMI 2.0. Also, the USA doc indicates, at 3 displays, all 3 4K drops to 30Hz. However, I don't rule out the AU version is better.

      If this is DP 1.4 version, then I wondered why it is so cheap and lacks daisy chain support.

      • The user guide says it's DP 1.4 and HDMI 2.0. RRP is almost $400 so not that cheap :) Didn't check re daisy chain though.

        Yeah, might be a regional difference. The dock/screen combo matrix I linked shows 3x 4k@30Hz for some lenovo laptops, but it supports up to 2x 60Hz + 1x 30Hz with others.

        • Okay, if you have a compatible Lenovo laptop with Intel 12th gen mobile CPU with Thunderbolt, this dock will let you do 2 4K/60Hz external + 1 4K/30Hz external. There is zero mention of whether HDR is supported or not.

          However, with some Lenovo devices, you might be limited to 1 x 4K/30Hz external OR 2 x 1080p external. I assume that's for devices not supporting Thunderbolt. Lenovo's documentation on this is not great.

          • @netsurfer: Agreed, their documentation isn't great. Also, what's with naming so many docks so similarly? It's a mess.

  • Any decent docks that can passthrough 144hz refresh rate monitors?

    This one seems limited - Refresh Rate 2 x 3840x2160 @60Hz, 1 x 3840x2160 @30Hz

    • +1

      I think you'd need a thunderbolt dock for that (if you're looking for good performance or to game)… Otherwise, if you look into DisplayLink docks, you might find something.

    • You'll wanna be looking for DisplayPort 1.4 stuff. I'm using a Cable Matters hub (https://www.amazon.com.au/Cable-Matters-Multiport-DisplayPor…) + another hub for USB-A ports, cause I couldn't find a full dock that didn't break the bank.

  • Got one of this from the last deal. It works perfectly, especially if you have multiple screens and a few other usb devices. Have tried many after market devices but they are not as good as this one. It's original Lenovo and it works well.

  • +5

    With lenovo laptops this works great.
    But With dell laptops I had issues.
    This is partly because of my organisation's IT support is too lazy to work on it.
    If it is your personal laptop you can update drivers accordingly .
    Anyway this is great price for quality docking station which can support higher power requirements .

    • +5

      I remember naively thinking we would leave all these driver issues behind when we went all went USB in the nineties

      And TBF, I have had dell docks that didn’t play well with HP laptops.

      I don’t understand why such simple things have driver hell.
      They should just work right out of the box, regardless of brand or even OS for that matter.

      This driver issue is a complete reason not to buy this. Bean counters (and bean counters it must be) should not get away with this kind of behaviour.

      • You are spot on
        These should work PnP irrespective of the brand.
        Unless we customers revolt organisations will keep doing things like these
        *You buy a multifunction printer and it wont scan or fax if one of the ink run out.
        *New Phones sold without wall chargers
        *Operating sytems remove backward compatibility..

        • So true - My Epson wouldn't print black if one of the colour cartridges was empty. Why !!
          Wall chargers I can understand. I've got a box full

          • @freesteakknives: Exactly.
            Wall chargers, New phones need more powerful chargers.
            They should give you a discount if not opting for the charger.

      • Any docks that works well without requriing drivers?

    • +1

      Thats interesting. In my company we use Dell Latitude 5320 laptops with Windows 10 and Lenovo 40AF docks with 2 QHD screens, and they work well together.

      I happened to speak to IT about this and they don't install dedicated drivers for them - the built-in Windows drivers seem to do a good enough job.

      What annoyed me is that this Dell can't drive my 2 4K screens at home, but that's a different story (crappy iGPU on 11th gen i5).

  • +3

    Works great with Fedora Linux, even does firmware upgrades.

    • Which device? Does it support 4K/60Hz with HDR through this dock?

      • +1

        I run a 27" Dell monitor (S2721QS) at 3840x2160 @ 60 Hz. It has Smart HDR but I haven't tried any movies or games.

  • I have one , also works with Samsung Dex , unsure of sound tho.

  • +2

    It's so confusing with what these things support. I bought a Lenovo USB c dock with 2xdp and 1xhdmi. I wanted to run 3 screens at 1080p. But this was not possible and one of the screens would run at a lower resolution.

    While the specs seemed to strongly indicate that it could do what I wanted (which is why I bought it!), it took a lot of researching to eventually come to the conclusion that it was not possible. In the end I had to run 2 monitors to dock and 1 directly connected to the laptop.

    I don't know if it's this dock or if this dock has the same issue. Just a heads up as I felt a bit tricked when buying mine as this info was not easy to confirm. It even had my Lenovo laptop explicitly listed as supported, but apparently it was a newer version.

    Edit: I think my Lenovo laptop only had dp 1.2 or something which is was caused it, ie it needed dp 1.4 to fully support the resolutions as per spec. Although it's possible that I'm misremembering the exact cause, I think this was the issue at least.

    Edit: I believe I have the "ThinkPad USB-C Dock Gen 2", which I believe is older despite the name? Who knows.

    • +1

      It's mostly due to your laptop. Anyway, going through the resolution support list for Lenovo docks is a pain and really confusing. You need to know the exact dock and the laptop (and hope the laptop is listed in the table, otherwise, you really need to know your laptop well to figure out what resolutions you can get with the number of external displays you are after AND whether the laptop screen is being used at the same time).

      • I still don't even know if my laptop would be able to run 3 screens with this dock or if it's the same as the one I have. They should (and could) definitely make it clearer.

        • Try to update the dock firmware and drivers. Lenovo has its own tool called Lenovo System Update. If just the dock, the app called Lenovo Dock Manager

  • +1

    Would this dock work OK with a Surface Pro 8?

  • -1

    Pretty sure these work with Mac, it looks like the same one at corporate office and you install the display link adaptor driver to get multiple screens

  • Can this extend with 2 monitors for Mac?

    • This will only drive one monitor from macOS, and given the explicit "Windows Only" in the name, Lenovo will provide no support.

      This appears to be a pure "USB-C DisplayPort Alt-Mode" dock.

      If you want multiple monitors driven from a Mac, you need either a Thunderbolt dock (best) or a DisplayLink based dock.

      • Thanks, appreciate it.

    • Most likely not. This appears to use USB-C/alt-mode with MST. Mac uses Thunderbolt with daisy chain to drive multiple monitors from a Thunderbolt / USB-C port.

      There is a reason why it indicates USB-C (Windows only).

    Smart enough to install critical firmware updates automatically, it is ideal for any mixed-PC environment and home office setting, and gives you the freedom and power to do more.

    makes it sound like you could connect it to your PC and laptop at the same time… I assume nothing like this exists to share devices on a decent level?

  • No usb 4 ?

  • I have a Dell Dock which is using with my Lenovo laptop. Is this worth to buy and any advantages? I have a Lenovo laptop. Thanks

    • +2

      When used with a Lenovo laptop, the power button on the dock will work for turning the laptop on; that usually doesn't work between brands.

      Also probably get MAC passthrough, but that isn't likely to matter to you.

      • Oh I see. It looks like there is not much advantages to use this dock comparing to my existing Dell dock. Thanks

    We use a lot of these at work. Windows does require a driver for the Ethernet adapter (Realtek). Make sure you update to the latest firmware.

    It will support up to 3 external display's but that is highly dependant on your laptops GPU or iGPU. You can find the matrix for supported resolutions here & the corresponding supported Lenovo laptops. I have a Lenovo T14 Gen1 with i7 10610U iGPU and I'm running 3 x 1080p external displays :
    https://support.lenovo.com/au/en/solutions/pd029622

    If you get display flicker on DP or HDMI port then there's a Lenovo DSC tool that will help fix that issue:
    https://pcsupport.lenovo.com/se/en/solutions/ht514019-extern…

    • Any idea if the DSC utility solves the issue where sometimes it doesn't detect the monitors at all until you perform an emergency reset on laptop?

      • I haven't heard of that issue with the USB-C docks. The older Lenovo docks, with the dedicated dock connector on the bottom of the laptop, I've seen with that issue tends to be solved with a firmware update. It's due to the Synaptics Display Port streaming hub interface in the dock. I had that issue with a UltraDock (40AJ) and the workaround for that was to swap the monitor output on the dock from DisplayPort to DVI as that was an option on the dock for that monitor output. When they released a firmware update that addressed it I swapped back to DisplayPort to the monitor.

    In my experience, if connect two or more monitors with Mac, won't be able to expand. Duplicate only. Windows was possible.

  • excellent, thanks OP, got 3x as we use these for our office at work

  • Will this work with Dell laptop? My dell uses USB C to power.

  • +1

    Sorry to sidetrack slightly, i have the Lenovo Thunderbolt 4 dock connected to my M1 Mac (I'm a new Mac user) with 2 external monitors. I have been unable to get both monitors to work if they are both connected to the dock, it just mirrors on both external displays, instead of extending.

    Instead I have to connect 1 to the dock, and one directly to the Laptop itself. Not a big deal but is there any way to get them to both work in "extended" mode when connected to the dock?

    This is the dock

  • Ordered 2 at 10am. Order cancelled. So disappointing…

  • Ordered at 10am yesterday, was told my order was cancelled. Probably won't buy direct from Lenovo again- pretty terrible service.

  • Got the dock today, hooks up to my surface pro pretty well out of the box. Will need to trial it a bit more to see if there's any issues with it.

  • Order also cancelled :(

  • Has anyone received their order via free standard shipping by any chance?

  • Order just cancelled. ;(

  • yep also cancelled here…

    Poor form Lenovo, product should have gone OOS automatically when allocatioin exhausted. Alternativley the rest of us who managed to actually submit an order before that happened they could have just put us on backorder and fullfilled once stock was available.
