    Would I get the same quality of sound if I connected my 2.1 Speaker system to the headphone output of my Benq monitor, as I currently do when its connected to the the audio out socket of my desktop PC?

    My JBL Creature 2.1 computer speaker system finally failed after 14 years, so recently, I replaced it with a Logitech Z623 2.1 set, which got me thinking sbout how I have my speaker set up. I have an Alienware Aurora Ryzen Edition 1.0.8 (never again!) as my main device and the speaker system is connected to its audio output port. So far, so good. I have no complaints with the speakers or the sound capabilities.

    I’m thinking of moving my PS5 from the living toom to the office, however. I don’t get to use it as much as I would like, as, while I do, others can’t watch the TV. (We use it as the main DVD player in the house, so if I do move it to the office, I’ll need to buy a 4K Blu-Ray player to replace it.) It’s not convenient to readily swap the phono cable for the speaker from the PC to another device.

    I have a BenQ EW2770QZ connected to the Alienware. This monitor has two HDMI inputs, internal speakers (which are adequate, but nothing special) and a headphone jack. My question is, is it feasible to connect the Z623 input to the monitor headphone output, thus making the speakers available to both the PC and the PS5? Would I lose anything in terms of quality or volume by doing this? Does the headphone jack deliver enough signal to drive the Z623 adequately?

    Thank you for reading this far.

      I tried connecting my SonaVERSE UB2 speakers to the headphone jack on my Dell U2417H monitor and, while the sound “quality” was fine, the “volume‘ was very low (i.e. not really audible more than ~foot away from the monitor with the speakers placed on each side of it.)

      And that was with the speakers “built-in” volume (there’s a nice big knob on the front of the right-hand speaker) and the PC’s sound volume both maxed out!

      I think the problem was the fact the “audio” was being piped to the monitor over the HDMI connection from my Nvidia GeForce GTX 1060 graphics card and the Nvidia HD audio driver just wasn’t that great (either that or maybe the monitor has a “built-in” volume limiter for the headphone jack since it is suppose to be used for “over-your-ears” speakers.)

      With the same speakers in the same position on each side of the monitor but plugged into the rear audio output of my desktop PC (SupremeFX8-Channel Audio using a RealTek HD driver), I had to turn the “built-in” speaker volume down to ~75% and set my PC sound volume to 50% to get a comfortable sound level (not too loud when sitting in front of the monitor and it’s still audible from up to 6 ft away.)

      Of course, YMMV.

      It’s not convenient to readily swap the phono cable for the speaker from the PC to another device.

      You can use an audio switch with input from PC and PS5, then select with a switch which sound goes to the speakers. The link below shows one such device.
