The display supports it's full resolution and refresh rate over HDMI 2.1. It's just not working right now at full rate over HDMI with either AMD or NvIdia graphics cards for some reason.

The table included in this article is misleading, as they've cropped off the original Korean text which states that it's currently not working at 240Hz over HDMI 2.1 with AMD either but that they contacted AMD who said it would work with a future driver update. The only reason that NVIDIA is listed at 120Hz in that table is because Quasarzone didn't get a reply from NVIDIA in time for publication.

It's unclear why no cards can do 240Hz over HDMI with that monitor when it's in spec.

The display only has one high refresh HDMI port (out of three), but that input is limited to 120Hz. It's stamped on the shell and listed as such in the manual, so it would appear to be on Samsung.

240Hz on this display requires the use of DisplayPort, which is what makes it a perfect (well, imperfect) example.
