With HDMI, I have both video and audio traveling over a single cable. That is _extremely_ convenient. DP _theoretically_ supports audio too, but AFAIK that's not widely implemented.

Unfortunately HDMI audio is also notorious for often having serious lag, both in absolute terms and relative to the video signal.

It was very convenient for me to have my headphones plugged into the monitor. Made it so I could plug a single cable over to my laptop and have basically everything else already done.

I personally prefer HDMI or DVI, I don't like DisplayPort because on the display that I have, when I turn off the display the computer detects it as if I've physically disconnected the display, which then moves all the windows that I had open around and breaks my macros...

Sounds like an OS problem. When I do that it moves all open windows to the remaining display, but when I turn the other display back on it just moves them back. No special software installed for this, just stock macOS Ventura.

But when I turn off my displays that are on HDMI or DVI or VGA, the computer still detects them like normal, like they're connected, because they are.

I don't understand in which case the 'act like it's physically disconnected' behaviour would be more desired than what we had with all the standards before.

I have read that some DisplayPort displays do have an option in the settings to disable this behaviour.

I just wish there was only one connector. Either HDMI or DP. I don't care.

I've always been surprised there aren't more receptacles out there that accept either a DisplayPort or HDMI plug. I've only seen it on one motherboard, but in retrospect, it seems obvious that the DisplayPort plug was designed to facilitate such a thing.

HDMI predates DP by 5 years, switching wouldn't enable any specific use case, and that 5 years head start means HDMI has market inertia. Yes we should use it because it's better but the practicality? There's so much gear that's HDMI that would have to be replaced or require new active adaptors. It's so much industry and consumer effort for such a marginal gain.

My monitor is fairly old, but it only does 30Hz on the hdmi cable and 60Hz on the display port cable. I'm not sure the exact versions. I think its displayport 1.2 and HDMI < 2. So for me, it was super important to get display port out.

One extremely convenient situation for me is getting sorround sound from the TV to the AV receiver in a single cable.

That sounds cool but I've never see a monitor with a jack. Mine all have many USB ports, but not audio. How common are they?

Are you sure that it's related to HDMI? TVs often do processing on the video signal which introduces lag, but my Samsung TV in "PC Mode" is virtually lag-free (and I use Logitech's receiver for my mouse because Bluetooth feels slightly too laggy for me).
