LG Gaming Monitor Sound

Sandi1987 · Aug 12, 2023

I will buy new LG Gaming Monitor. Monitor have Audio Output (Headphone Jack). Will be enable to get sound with headphones because monitor doesn't have Built-In speakers?

I presume so.

However, if you supplied the model number, it'd be possible to check.

Yes. Or you can connect a powered speaker to it.

I wonder if there would be any sound quality difference between the monitor output and the onboard sound output.

There shouldn't be. The sound is still processed in the onboard sound. The audio is just extracted by the HDMI cable. It is just like splitting your audio source. The only good thing about using the monitor output is that the volume controller is right in front of you (on the monitor itself) if you want a physical volume controller.

Audio in an HDMI cable is digital.

To drive headphones when the monitor is connected by HDMI, there must be a DAC in the monitor.

I doubt that most of us could hear major differences among different DACs, but audiophiles might disagree.

I know I couldn't hear the difference. Years of working around loud noises, I now have to wear hearing aids. So to get true digial sound the monitor would need a HDMI output?

Sorry, but I don't understand the question.

I normally regard a monitor's HDMI as an input (both video and audio). DisplayPort also supports digital audio.

You said the HDMI sound input to the monitor is digital and the headphone jack had to use DAC for the output. so I was curious to know if the monitor could use a HDMI output to keep the digital sound. I only asked because the soundbar on my TV can use an HDMI input for the sound. It's been so long since I set it up that I forget if I used the HDMI input or the digital input.

They usually just call it an hdmi audio extractor. Just splitting the audio and video signal and outputs an analog audio. Not sure if a DAc is involved in between. Maybe.

The HDMI audio extractors that I know of separate the video and audio, to send a UHD (sometimes called 4k) video signal to a TV and HDMI (digital) audio to an older AVR (audiovisual receiver) that doesn't support 4k. Maybe there are devices that convert the HDMI audio to analog, for use with analog audiophile gear, but I'm unaware of it. (My own choice is to stay digital as far as possible through the audio chain.)

By definition, analog headphones would require a DAC (digital to analog converter).

I don't know whether digital headphones are common. My desktop speakers are connected to the PC by USB (digital), which means that the speakers (KEF eggs) include their own DAC. The same would have been true if I used the optical interface. Maybe some 'phones could be similar.

There are monitors that offer HDMI passthrough. (That provides an HDMI output that is the same as what is input to the monitor.)

Using a splitter is another option, to do perform the same function.

Do you need that?

About as common as digital speakers, which means next to non-existent,

Digital speaker - Wikipedia

Anything claiming to be a digital speaker is not a true digital speaker. All it means is that it can take a digital connection and uses its own internal DAC to convert the signal instead of the onboard (S/PDIF, coax, or optical) or the one integrated into the video card (when passing audio over the HDMI connection). No matter how you slice it there has to be a DAC somewhere between the source and the speakers/headphones in a digital connection.

I'd be disappointed if there is anyone who doesn't realize that.
