One monitor is zoomed in if I connect two 4k60Hz monitors to a Thunderbolt 4 dock.

When I enable two monitors to work simultaneously on a Lenovo Thunderbolt 4 dock station, one of these monitors always gets zoomed in (as if it were cut off).

Steps to reproduce:

1.Turn on the laptop.

2.Connect the dock station to the laptop.

3.Connect one 4k monitor to the dock on DP port 1.

4.Connect the other 4k monitor to the dock on DP port 2.

5.At this point, when the dock is connected to the laptop and the monitors are connected to the dock, neither monitor displays an image (yes, that is a problem, but it is not my biggest problem, for now.), but the system shows that they are connected (both via the Ubuntu panel and via xrandr).

6.Decrease the resolution of one of the monitors to FullHD (at this point, this monitor displays an image at FullHD resolution, and the other monitor displays an image at 4k resolution).

7.Increase the resolution of the monitor back to 4k. Now both monitors display an image at 4k resolution, but the monitor whose resolution was changed to FullHD and then back to 4k has a zoomed in image.
