This port doesn’t support desplays for AMD laptops(chip limitation), All the rest support displays although the front(closest to the touchpad) right is only USB 3.1. Not sure how you managed any screen activation from that port at all? Have you tried other Framework slots with your dock?
I believe you’re incorrect, see here : https://cdn.kustomerhostedcontent.com/media/6047cd84502177bce9fccae2/45dca0f92f2dc1d875ea4e2de1a4d9ad.png
In my case, 1 and 3 were USB-C expansion cards, and I was using 1 (it worked once) but seems to not work consistently, although I haven’t done enough testing yet to confirm exactly a reproducer.
And also this knowledgebase : Expansion Card Functionality on Framework Laptop 13 (AMD Ryzen™ 7040 Series)
You wrote front left, 1 and 3 are the back ports (on screen side)
You’re right, I’m sorry, I didn’t communicate properly, I’ll be more careful next time.
But it was, when you’re in front of the screen the two furthest ports (the one at the rear/closer to the back side) from the user.
I would not recommend the Anker 577 Thunderbolt (13 in one). Every time the laptop is turned on, I have to unplug and replug the dock or the monitors will just continuously cycle off/on every few seconds. Anker’s tech support suggested just unplugging it every time…which is a pain.

I just got the 13 Ryzen laptop and installed Fedora 39. I use a CalDigit TS3 Plus for my work MacBook, so I tried that, and all my USB peripherals work fine. My monitors both show up as 640x480 “Unknown Display” when I connect them through the dock, but work fine when connecting directly via the HDMI expansion card. I’m connecting the thunderbolt output from the dock to the back left USB-C expansion card.
Probably going to try and buy one of the other recommended docks from this thread, but posting to see if anyone has any suggestions for ways to get it working, I’m a desktop Linux n00b.

I have a Framework 13, Intel 13th gen, running Windows 11. I use an Anker PowerExpand 8-in-1 USB-C dock, Model # is A8380. It works fine both using the charger (Anker 737 GaNPrime) through it and also plugging it in without the charger to use its card reading and ethernet functionality. The HDMI’s also work even without the charger.
I use it for the non-profit penny social auctions I help with.
I can update the table if it’s not already on there, once I figure out how to use the Wiki function on this forum. This one maybe a good option for those who don’t want to drop $200 to $300 on a dock. This one is usually under $100.

Hi, @D_Smith, @Foxtrek_64, @Alec_Jurisch, @Antoine_Chatelain
I would like to know if people who have this USB-C dock base can reproduce the issue I’m facing with the FW 13 AMD or FW 13 Intel.
TL;DR
Every devices works beside the external screen that is plugged via HDMI on the USB-C dock.
The external screen works with a Lenovo Thinkpad T495 laptop but doesn’t with the FW 13 AMD.
However, if I plug the T495 and then unplug and plug the FW 13 AMD, the external screen starts working on the FW 13 AMD and also other laptops (an Intel one).
I have an interesting finding with the Thinkpad USB-C Gen 2 AS40 (I will confirm the exact model number in a coming edit), if I plug in my Lenovo T495 AMD laptop on the USB-C dock, the screen and USB devices work.
Then, if I suspend the Lenovo laptop and unplug the USB-C dock and plug it into the AMD FW 13, the external screen plugged into the dock do not come on.
However, if :
- Plug T495 on the USB-C Dock Gen 2
- Unplug the T495 (do not suspend the laptop while having the Dock plugged in else it won’t work)
- Plug the AMD FW 13, the external screen works.
Important note during my testing : I have tested this with a 60W charger plugged into the FW 13 AMD on one side and on the other side, I was plugging the USB-C dock, thus the USB-C dock wasn’t providing power.
I have also reproduced this issue/workaround with another Dell Intel 12th gen laptop.
I wonder how I can investigate more thoroughly, or if I need something like an USB-C logic analyzer thingy to capture the USB communication.
EDIT :
Suspending the Lenovo T495 Laptop while being plugged to the Lenovo USB-C dock gen 2, breaks the external screen for the next laptop that gets plugged in if it isn’t a Lenovo laptop, not sure what’s going on.
Hi,
The dock is now working great with my Framework. I did not change anything and when I came back from holiday (I did not intentionally update any drivers/bios/firmware). But now I can charge, connect an external display and access USB devices without any problems.

Which dock you’re talking about?
He’s talking about the Thinkpad USB-C Gen 2 AS40 dock
The Lenovo USB-C Gen2
Right. From the looks, it almost looks like my Dell Dock WD19TB.
Bet it’s all made in China/Taiwan - and they added some stickers for branding :}
Big OEMs share suppliers, so it could be the case
Could any FW AMD owner please upload a screenshot of the Windows 11 USB4 Panel?
I have been asked to prove that AMD is limited to a single DP connection per USB4 port, but cannot find any existing screenshot actually proving this.
For reference, this is the panel I am talking about on an Intel/TB4 machine, where it shows that as required by TB4 2 DP connections are available and I believe AMD to only offer a single connection.

Found another user that was nice enough to post a screenshot. Problem is, that does not show what I expected.
I tested this myself a good while back with an AMD 6000 CPU and an older Win11 version without the USB4 panel.
And I recall reading over some threads here, where users reported situations, where their dock would not output a 2nd DP connection on FW13 AMD and took that as confirmation, that my experience must have been representative.
Has anybody with an AMD FW managed to extract 2 DP connections / tunnels through a single USB4 connection? Or is it more that Windows thinks there are 2 DP connections, but it never actually works?
To reliably show that AMD’s USB4 implementation can do that, we would need some kind of TB3 or TB4 dock, that internally uses both / can use both DP connections. Any TB4 hub (3 TB-outs) is the easiest, as if that drives more than 1 display, it is because there are 2 DP connections.
But docks with MST can still be used, if they give access to the 2nd connection, even if not intended.
For example, my Dell WD19TB dock uses only a single DP connection internally for the DP & HDMI outputs (using MST), which is why all of those also work on USB-C/DP Alt mode.
If any of those outputs are in use for 1 monitor, the TB-out on that dock can provide a 2nd DP connection if the host provides one (although it will be throttled, due to the dock prioritizing its main outputs, but it will still detect a monitor and allow to drive that at like FHD@60).
Just as a warning: The Lenovo TB4 dock is weird. While it’s TB-out it labeled TB and can do that, it is wired up in 2 different ways and can also be driven via MST on non-TB/USB4 hosts. So a 2nd display on that dock, even when using the TB-out would not be conclusive by itself and would require deeper investigation, which mode the dock internally chose to make that work.
Windows 11 also has a somewhat hidden debug option that can visualize the connections / tunnels through TB/USB4 in case someone is interested. This is behind the “Device Portal” under System>For Developers. Requires enabling Developer Mode, installing the Device Portal feature and rebooting after enabling it (can also be quickly disabled again just by flipping the Device Portal switch off). That hosts a website locally (by default only available from the device itself) that has a USB4 page that will sketch out the entire USB4/TB3 topology including active USB3, PCIe & DP tunnels.
(Here a screenshot of what that would show. near the root of the topology you can see the 2 DP tunnels and to which device/port they are routed to)
Edit: Oh and for my Linux friends: the “/sys/kernel/debug/dri/1/amdgpu_mst_topology” sysfile should report enough about the MST-topology to determine whether MST is involved or any given monitors are sharing a DP connection. Sadly I do not know better ways to debug how TB/USB4 uses DP tunnels.

Hi @p_e
I bought an i-tec docking station (C31DUALKVMDOCKP) based on the message you posted last year, and I can confirm that it works very well, but strangely it doesn’t like my two screens (11080p & 11440p) and forces my 2k screen to be in 1080p. I’ve checked with my two connected laptops and it’s the same thing. I’d like to have a few details about your configuration, because apart from one of my screens, we’ve got the same thing, and I’d like to understand what I’ve missed.
My research hasn’t given me much information, my clues being a possible blockage due to the difference in screen resolution, a question of updating the Intel graphics driver or even the station firmware (i-tec having already mentioned on a post a problem already observed similar to mine on other models).
Here are a few details in case anyone else has an idea:
System: Ubuntu 23.04
Firmware: 03.04
GPU: Intel Graphics (ADL GT2)
Kernel: Linux 6.5.0-15-generic
Thank you in advance for your help 
Hi @Louis_BERTHET ,
I am still daily driving my dock with the same two monitors and still don’t have any issues.
As I mentioned my displays are two 2560x1440 monitors both running at 60Hz refresh rate (Maybe it is an issue with the refresh rate ? The dock lists it is only capable of doing two monitors at 60Hz). Both are from different manufacturers.
Out of curiosity I tried lowering the resolution of on one of the displays to 1080p, this works fine for me. The new resolution is only outputted to a single display, the other display remains at 1440p. So this should rule out the dock as a limiting factor.
I am currently on Fedora 39 with Kernel 6.6.14, but I have used Ubuntu before that (I daily drove it on 22.10 & 23.04 for a long time until the upgrade to 23.10 failed miserably and I decided to give Fedora a try).
On the Bios side (I have a 12th gen), I did start on 3.05 and recently directly upgraded to the 3.08 beta. For me that did not change anything with regards to the dock behavior.
Additionally I also always install the intel-media-driver, mostly to enable hardware acceleration in firefox.
Hi @p_e
First thank you very much for your reply 
I see, in the meantime I’ve upgraded to version 3.06 of the bios and I’ve totally reinstalled my ubuntu to the latest version (23.10), but still nothing. I keep having the impression of observing a bandwidth “limitation” for my screens through the dock or at PC level; when I unplug the 1080p screen, the other ends up with its 1440p at 60hz. I’m left with two choices:
- Install Intel Media Driver and hope it does something on the graphics side of the card.
- Check which standard the video stream is currently running under (despite my research on the subject, I still can’t tell whether the dock is running under usb-c, TB4 or USB4, as I can’t find any visual indicator in the OS to tell me).
If you have any ideas on the subject, I’d love to hear from you.
