It is important for readers to be aware that the specs compared are not useful today.
Only the latest greated 50x NVIDIA gpus will do DP 2.1 (everything else is DP 1.4). And likewise, even your best monitors are unlikely to support DP 2.1 today.
HDMI 2.x is supported by a wider(est) array of available GPUs and monitors, and thus not only wins out, but is literally the only way to unlock the resolutions and refresh rates in today's situations.
