Unfortunately HDMI audio is also notorious for often having serious lag, both in absolute terms and relative to the video signal.
Sounds like you need to upgrade to gold plated HDMI.
Better get that Monster Cable!
Displayport: A Better Video Interface

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.
> headphones plugged into the monitor 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?
An audio jack is very common. Some even come with speakers. They are usually not very good but they get the job done in a pinch.
I use 2 computers connected to the same monitor via hdmi and use barrier (and a script) to switch screens. The audio for the correct monitor gets activated automatically. It's very convenient.

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.

But since they’re off, that doesn’t make any sense, now you can’t reach any windows on those monitors. I think the macOS behavior make the most sense, move them so you can access them, but move them back once the display is turned on.

#54If we lived in a just, and virtuous world we'd all be using cheap coaxial cables with BNC connectors via whatever version of SDI is the highest bit rate.
SDI can't do any communication between the source and sink. You can do a limited form if you use two SDI cables (one upstream, one downstream) which is what stuff like BlackMagic's bi-directional micro converter does, but IIRC that's only used for talkback to the camera operator and HDMI CEC messages which is how they implement things like their ATEM Mini consoles triggering recording - not for DDC-style format and framerate negotiations.
Also, device manufacturers don't do SDI on consumer devices because SDI is by definition unencrypted and uncompressed, so it's at odds with HDCP.

#55With 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.
Isn't the whole idea of routing the audio through the display that it can compensate for any lag due to processing of the video signal? I haven't really noticed any problems with HDMI, and if I did, I think I would blame the display.

#56I'm annoyed nvidia for putting the current generation of HDMI on their recent GPUs, but leaving them with an outdated version of DisplayPort. For a long time, my advice to anyone was to always choose DisplayPort whenever it was an option. But now that has to have the caveat of "if you have a new high-end GPU and a fancy high refresh rate monitor, HDMI might actually be better for your situation"
And only 1 new version HDMI port but 3 old version DP ports. I use a dual display setup but HDR only works on mu displays with HDMI.

#57Sorry if that sounds stupid, but why isn't Ethernet used for this sort of high bw signaling?
The bandwidth is much too low.

#58I didn’t realize Multi-Stream Transport (MST) requires OS support, and I was surprised to find out MacOS, with its great Thunderbolt support, does not support this. “Even” ChromeOS can do MST.
Re: Displayport: A Better Video Interface
#59I 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...
I /think/ this is related to the EDID support or configuration.
What I do know is that you need specific EDID support when using a DisplayPort KVM because that switches the computer away on a regular basis. If you have multiple screens and a single screen KVM (fairly common) it will do the re-arrangement that you've experienced. With EDID support it keeps both output alive resulting in no re-arrangement.
EDIT: It seems the correct term may be "EDID emulation".
Re: Displayport: A Better Video Interface
#60This post was informative and I didn't realize just how different DisplayPort is from HDMI. Recently, I got a desktop dock that uses DisplayPort instead of HDMI to connect to my monitor. My monitor has 2 HDMI ports, 1 Type-C, and 1 DisplayPort. So far things have been fine but I did notice that the audio is choppy no matter what I do. I thought it was the dock but audio going from my computer > dock > my webcam's spe…
It might be your dock.
Check to see whether it's USB or Thunderbolt. Thunderbolt docks are more expensive, but considerably more efficient and faster than USB (assuming your laptop/device supports Thunderbolt).
Thunderbolt docks are basically PCIe extension devices, whereas USB docks attach everything as USB, with all the common challenges USB has on systems (like dropped audio when the CPU is busy).
