Best way to connect a 4K monitor to Macbook Pro mid-2015 retina

Hi

I've currently got a 4K Samsung monitor connected to my mid 2015 Macbook Pro Retina via a high-speed HDMI cable. I get the additional monitor settings (text-size) and it works great. Except for its a bit laggy, especially some screen savers (for example Flurry).

I was just wondering if there is a better way to connect than the HDMI port or whether I need to change any other settings to reduce the lag?

Thanks

Yes.

DisplayPort family is a much more advanced interface. It [finally] drops the "heartbeat" refresh required for CRTs. This leaves more room on that cable for fresh data, and it tends to have higher effective bandwidth, higher refresh rates, and run the Hardware a bit cooler.

HDMI is a consumer-grade interface invented for HDTV at 1920 by 1080, and other uses, like stretching it to 4K, can be problematic.
