Dell Precision 3480 Laptop + Dell Pro Smart Dock SD25 = 3840x2160, 30Hz at Dell S3221QS Monitor via HDMI
Hello everyone,
I've been using my Dell Precision 3480 laptop with my 1x Dell S3221QS 4K UHD monitor for a while now. It works flawlessly and gives 3840x2160, 60Hz over HDMI. I recently purchased a brand-new Dell Pro Smart Dock SD25 and connected all my cables to it, including HDMI. I expected to see the very same refresh rate, however, I'm now getting 3840x2160, 30Hz only.
Did I do something wrong? Is there a way to get 3840x2160, 60Hz over HDMI using this dock? Thanks in advance for your responses!

Have you updated the Docks firmware and other Driver here?
To receive assistance from Dell chat support, they need to verify the warranty status and ownership. Then you must troubleshoot with them. Click the "Get Help Now" icon on the right to start a live chat session. If already out of warranty, click here for the Dell out of warranty offering.

Yes, I have updated the firmware and other drivers. Unfortunately, it didn't help. The dock still gives me 3840x2160, 30Hz via HDMI.

Guess DisplayPort is not viable
