Both HDMI and DisplayPort carry sound over the wire if that makes a
difference and both can do 4k (3840x2160). However, HDMI is limited to
30FPS as far as I can tell whereas DisplayPort can manage 60FPS at
that resolution.

false. hdmi currently supports up to 120 fps:

€ 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video
resolution

€ Higher video resolutions support a range of high resolutions and
faster refresh rates including 8K60Hz and 4K120Hz for immersive
viewing and smooth fast-action detail. Resolutions up to 10K are also
supported for commercial AV, and industrial and specialty usages.

I guess the information I had was outdated. It turned out that what I
said was true but only of the early versions of both HDMI and
DisplayPort. New versions are capable of exactly what you say. In the
user's case, he will have to make sure that whatever he purchases is
of the later spec.

it depends on resolution. 720p and 1080p @ 60hz is supported all the
way back to 1.0, but those aren't high res.

I was only suggesting that the 30FPS limitation was at 4K resolution,
not any resolution lower than that.

Still, I thank you for your up-to-date information and feel that it
benefits us all.
