Hello Katarzyna,
for 5120x2880 yes, but not for 5120x
1440. 4K is supported with one cable, so 5120x1440 must also support one cable because the overall resolution is smaller than 4K.
Following resolutions are supported when connected via Docking Station:
4K is the maximum, but still wrong.
The problem is mentioned via suggestions as well:
