This bug is awaiting verification that the linux-oem-6.11/6.11.0-1010.10 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done- noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed- noble-linux-oem-6.11'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

DDI function [Test] Connect 2 4k@60hz or higher resolution or higher refresh rate monitors to the dock and connect the dock to the DUT, the external monitors should work well. [Where problems could occur] It may affect the disply output through dock on both Intel and AMD platforms.
