I would kindly ask the HDMI forum to point me in the direction of a DP to HDMI adapter that supports VRR or FreeSync. They seem so motivated to gain more funds from royalties, surely they know how to persuade me.

Anyone wanting to know more about it and the island Tuvalu, see: https://en.m.wikipedia.org/wiki/.tv
Certainly not an expert here but the GUI "being there" means you can configure something about the traffic flowing through, maybe VLANs or QoS. That also might be why some switches have fans. Deciding what packet has priority or is allowed is a bit more computationally complex (read: heat generating) than just pushing a packet to the right address.
You might want a VLAN if you have a server connected to the same switch as your PC, but they shouldn't "see" each other. If you didn't have a VLAN there, your router or firewall can't manage anything about the connection. Say you have a website and database on your server and only the website should be accessible by your computer, you'd be able to configure that with the firewall.
It's not the adapter I bought, but also seems VRR is lacking:
"VRR/G-Sync/FreeSync are not supported."
Have you experienced otherwise?
