Why does my System>Sound>Properties show that my LG E2742 monitor has audio 
capabilities, when clearly it does not?

It has according to the spec:

<https://www.lg.com/nz/monitors/e2742v/>

You need to connect via HDMI (or display port but you don't have it) to 
get the sound from the monitor. I have a similar version but from Amazon 
Basic Range and the sound is pretty good. I bought the monitor because 
it has three input/out ports - VGA, HDMI and Display Port. These days 
most monitors don't have VGA ports.

According to the manual the V series has a headphone out jack.

Thank you.  I looked more closely at the back of the monitor, and you are
correct.  There's a 3.5mm head phone jack.

The desktop (Dell XPS 8950) display port is connected to the monitor's
HDMI port.  And upon closer look at the model number on the back of the
monitor, it is an LG E2742VA, and it does have a 3.5 mm (blue) jack on the
back of the monitor. 

Not sure why I would ever use the jack, since my speakers are conected to
the back of the desktop, and the desktop does have a head phone jack on
the front of the tower. 

Thanks.

It doesn't have internal speakers, but it has HDMI in and headphone 
socket out ... so it is an audio target.

The HDMI is not a full PNP (Plug and Play) subsystem.

It tends to be unidirectional.

The status or existence of any audio sink on the
monitor end is unknown.

The OS knows whether a bus termination has been plugged
to an HDMI (or DP or VGA) connector. It can then route
a video signal to the load, knowing that it's not creating
RF emissions by the cable end being open.

But audio carriage on the cable, there is no mechanism I'm aware
of, which commonly can talk back and relay information about
whether there are speakers or an audio sink. That's more or less
best effort (works, if you have speakers, otherwise the bytes
go into the bucket).

Since there are hardly any questions about Dolby, I would
guess that most people consume movie content, with 7.1 LPCM
as the audio track, rather than Dolby flavors of coding.

Probably to give nit-picking ninnies something to carp about ;-)
