The only real benefit to HDMI over DVI is that it carries audio where DVI does not, which is why it’s used on so many TVs. I know DP can do audio too; so I’m not even going to touch on that. DVI however, can do dual-link, which IMO, makes it a much better video format regardless of any patent nonsense.
From a signaling perspective, they’re very very similar. Given that all TVs have HDMI, it may be the only option.
DVI? Yes, basically HDMI is DVI guarded by patent trolls. DisplayPort? No, it is packet-based.
