the iiyama GB3461WQSU-B1 display won't be recognized correctly at the display port 1 of the Ultra Dock.
-> 640 X 480
-> Windows 10 x64
If the display is connected to mini display port on the Lenovo ThinkPad X260 (Type 20F5) it will be recognized correctly.
If KDE neon 20.04 LTS is booted via USB stick on the ThinkPad, than the display will be recognized correctly on display port 1 of the Ultra Dock.
After reinstalling Windows 10 the intel graphics driver 184.108.40.20673 was installed from Microsoft, everything worked fine.
Then version 220.127.116.1112 from Lenovo was installed and the system was f*cked up.
So another reinstallation of windows 10 was done, then version 18.104.22.16887 from Intel was installed and the system was f*cked up again.
Thank you for posting on the Intel® communities.
We understand that after reinstalling Windows®, the latest driver from Lenovo* (22.214.171.12412) and from Intel® (126.96.36.19987) were installed and the problem persisted.
However, just to rule out driver installation issues, we would like to recommend a clean install of the Lenovo* graphics driver following the steps in the following link:
Note: Before performing the steps, make sure your system is running the latest Windows® version 2004 with all the latest (minor) updates available.

Lenovo's Intel HD Graphics Driver* 188.8.131.5212 >> https://pcsupport.lenovo.com/cr/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-...
We also recommend checking with Lenovo™ support if there are firmware updates for the ThinkPad Ultra Dock Type 40A2. You may also check with the display manufacturer if they also have firmware or drivers for this specific display.
If the issue persists, we recommend checking this further with Lenovo's support since the problem seems to be related to a limitation or compatibility issues of this configuration (laptop-display-docking) since as you mentioned the display works fine when connecting directly (without the dock) to the laptop.
It is worth mentioning that Intel does not recommend the use of any kind of adapters or dockings. This is because we cannot test all of them, so we cannot guarantee that these are going to work.
The best solution is to do a direct connection with a single cable that has the same connection type on both ends. For more information please refer to the below link:

NOPE ... already the newest
Lenovo ThinkPad x250 on exactly the same Dock is working without any trouble.
"It is worth mentioning that Intel does not recommend the use of any kind of adapters or dockings. This is because we cannot test all of them, so we cannot guarantee that these are going to work."
WTF ??? are you serious ??? What's the sense of a docking station ???
"The best solution is to do a direct connection with a single cable that has the same connection type on both ends. For more information please refer to the below link:"
This is ridiculous ... again with 184.108.40.20673 everything works fine ... so your newer drivers are sh*tty ... like Volkswagen ID3 Software
First of all, it's not Intel's job to test every dock, dongle and adapter that is out there. Half of them Intel will never even have heard of. It is the vendors for these docks, dongles and adapters that are responsible for their operation and interoperability. Secondly, half of these devices do not meet industry specifications, so don't blame Intel for them not working.
I agree with Al, your bad language is not appreciated.
Thank you for your response.
It is worth mentioning that our support is only provided in English. We may not be able to translate screenshots attached to the thread.
The information provided by n_scott_pearson is correct meaning that we cannot test all the adapters or dockings from third-party manufacturers and we cannot guarantee their compatibility.
Also, just to clarify regarding the Clean installation of the driver that we recommended (we were not referring to Clean install of Windows), based on the chronology of your post, you mentioned that you first "performed a clean install of Windows® and installed the graphics driver 220.127.116.1112 from Lenovo". Then a "second clean install of Windows® and Intel® generic driver 18.104.22.16887 was done".
In this case, we understood that the latest driver installed on the system at the moment was the Intel generic driver. Since we wanted you to test with the OEM driver, the Clean install is the recommended process (despite it is a fresh install of Windows) due to the following reasons:
We understand your point when you said that "an old driver works fine". However, that old driver could be the latest one compatible with this configuration (laptop-docking-display). The driver or software for your Intel® component might have been changed or replaced by the computer manufacturer and we provide only generic drivers for general purposes. OEM drivers are handpicked and include customized features and solutions to platform-specific issues. Your computer manufacturer is the one responsible for customizations of the latest Intel® drivers.
The Intel® generic driver is working as expected under normal use (when used in straight-through connections: computer <> display) and the problem has been identified/isolated to the docking (it is triggered when connecting the docking and placing it in the path between the computer and the display). Hence, if the issue persisted we recommend addressing this to your OEM since they may have access to this configuration/hardware so they can debug further from their side, or you may stay with the old driver until your OEM releases a new customized graphics driver. Actually, it is a good fact and starting point when you mentioned that "the docking works fine with another Lenovo™ laptop", so your OEM may assist you further to diagnose the differences in those configurations.
