Can my T530 connect to an external 4K monitor via DVI port?

[edisonn]

I connect a 4K monitor to my T530 via the DVI port in the docking station, but the max. resolution I can adjust is 1920x1080. Is there any way to change to 4K? Thank you.

You have to use DisplayPort to get 3840x2160.

However, the T530 supports 4K only at a refresh rate of 30 Hz as far as I know.

You might be able to get 3840x2160 on DVI by setting a custom resolution at 30Hz using Intel Control Panel or NVIDIA Control Panel (depending on whether you have Optimus).
