Thanks for the prompt reply but further documenting about the U2312HM and compatible soundbars on your site I found that AX510PA is listed as compatible while the AY511 isn't. Still a bit confused.
AY511, AX510PA & AX510 are compatible with U2312HM
* AY511 - Better spec than AX510PA / AX510
* AX510PA - Basically is AX510 shipped with extra power adaptor (PA) for monitor without DC Power Out (12A) jack.
Dell P and U series monitor (including U2312HM) are equipped with DC Power out jack, so you could rule out AX510PA. Your choice of soundbars should be either AY511 or AX510.
Hope this help.
Dear Dell Support, please can you reconfirm that the AY511 is compatible with U2312HM? The reason is that this monitor is not listed under the compatible monitor for AY511.
The AY511 doesn't connect to the monitor but comes packaged with a separate adapter. My advice is, just go ahead and buy it, both the monitor and the soundbar are awesome and the look of the two together is terrific.
I have have bought the monitor, so just considering different options for the speakers. I thought there is an power connector for soundbars on the back of U2312hm monitor. What is this for if AY511 needs a separate power adapter? Many thanks again for your advice!
