Hello everyone,
I have a Lenovo ThinkPad T480s laptop running Fedora 39 Kinoite. I would like to use it in a multi-display setup, so I am looking for a docking station. The laptop has a Thunderbolt 3 port. I have attached the details of my device at the end of the post.
People on Reddit are writing that “all Thunderbolt docking stations should work fine” and that’s obviously not the case… I have this Dell Thunderbolt Dock (WD19TB) at home from work and the displays work when I plug it into the laptop but, for example, my mouse (connected via USB-A) doesn’t work. When I connect it to the DELL laptop provided by the company, there are no problems at all.

Docking station requirements: Ethernet, 3x USB-A, 1x DisplayPort, 1x HDMI.
I have two 1080p displays: 75Hz and 165Hz. Obviously I’m not going to be playing any high-frame-rate games on this laptop, but even on a desktop it’s sometimes nice to see a slightly higher refresh rate. So if it’s possible, I’d like it to be able to display things above 60Hz…
I also have a Steam Deck OLED and would like to be able to use this dock with it.

I don’t want to spend too much money on it. Do you have any experience in this area and can you help me choose?

I am from Poland if it helps in any way (maybe some brands are not available here).

    Here is the model I’m using: https://www.lenovo.com/ca/en/p/accessories-and-software/docking/docking_usb-docks-(universal-cable-docks)/40ay0090us

    It’s the 40ay Universal USB, not thunderbolt. My AMD T14 would only work with thunderbolt in Windows, refused in Linux. No issues with Intel T14s. (We use strictly Lenovo products at work.) So this might be a better bet for you.

    The Z16 works with or without the correct power supply, a T480 should be fine with the one that comes with it.

    Not sure of your budget, hopefully it’s not too much for you.

      So you’re saying it’s safer to get this USB dock than the Thunderbolt one?

          From what I understand after doing some research, these USB docks are the DisplayLink docks, right? I see that people on Reddit are writing that DisplayLink adds some latency etc. so it makes these decs unusable when trying to play games. So I’m assuming it might not be a good idea to get one of those, as I want to use it with the Steam Deck as well?

            I cannot find anything that indicates the 40ay uses DisplayLink tech beyond a Reddit post without any credibility. Do a search for “40ay” “displaylink” and you should find a few places saying it is not a DL dock. Can’t seem to find any confirmation in either direction for one or the other, and I’m not sure my Lenovo rep would answer their emails this week :)

            Give me a list of games you play that requires high latency and if I have one of them I’ll test it for you. If not I’ll break out StreetFight 3 under FBNeo and see how it feels.

              Yes, you’re right. The 40AY isn’t listed here as one that uses DisplayLink: https://www.reddit.com/r/thinkpad/wiki/newdocks/ so I think that’s the best bet for me :)
              You can just have a look at the Counter-Strike if it’s not a problem for you, as it’s free to play. Thank you very much!

      On this page, in the list at the bottom, I can see both the T14 series and the Z16 series. However, there is no T480 (but there is a T490): https://smartfind.lenovo.com/accessories/#/products/40AY0090US So I am not sure if it fits… However, it does allow quite high resolutions at 60Hz (2x 3840x2160 @60Hz), so we can say with some confidence that 165Hz at 1080p won’t be a problem. At 479 PLN (~122 USD), it is still affordable. In general, the case with pricing is that I paid 2200 PLN (~559 USD) for this laptop and I just don’t want the docking station to be half the price of it :)
      I think I will risk it with this model, considering the resolution/refresh rate.
