I have a user with two LT3053s (2560 x 1600) and his previous T440 + Ultra Dock (I believe) supported the full resolution at 60 Hz (again I believe). I upgraded him to a T480 and our standard Type-c dock that we deploy limited the screens to 1920x1080 @ 60Hz. After this and complaints from the user of headaches from the drop in resolution we purchased a TB3 Gen 2 Dock and even after plugging the dock in to the actual TB3 port on the laptop (not the top type-c port) we are having issues with not all of his devices working, namely the kb+m.
Any ideas here? Right now we are running it with the 135W power adapter that it came with, but there is also another power adapter available that did not come with the unit we purchased.
