I notice lagging on the display port that is not present when I plug the same monitor directly into my mackbook pro using a USB-C to HDMI cable. The docking station HDMI port appears to perform well.
The performance between DVI and HDMI should be identical. This could be a limitation of the monitor, or it could be a cabling issue. Have you tried swapping out for a different HDMI cable? Also, what is the make and model if the display you’re using?
We haven’t heard back from you, so hopefully you were able to fix the issue. If not, please contact us at email@example.com for assistance!
