Q24i-10In my experience, Do Not purchase this product.Unfortunately Lenovo designed an overcomplex monitor that will take you hours apon hours to onboard for use.It is challenging to understand why Lenovo would make something as simple as a monitor so complex that the general population cannot get this monitor to work correctly for 'Sound.'I found myself in a rabbit hole of Lenovo phone calls, and chat supports, spending hours of time without resolve and not only without resolve, no one even tried to troubleshoot a suggestion for remedy.Be prepared on phone support for lots of wrong information, transfers, and hold times. One Lenovo Rep from the Atlanta Georgia phone support office informed me the monitor did NOT have any internal speakers.......seriously of course it has internal speakers.............so please be prepared for all kinds of off track responses.I was also on Lenovo Chat support for 1 1/2 hours with Lenovo Chat support asking me multiple questions more appropriate for computer science experts than a general customer.Again, 1 1/2 hours later I was still without any actual contribution or directions to troubleshoot the sound problem. Finally Lenovo Chat support requested to me if they could log in via remote to my computer assuring me how safe the Lenovo chat support remote system being used is. Please beware I googled the Lenovo chat support remote system.Beware and be warned there are many documented risks about Lenovo's chat support remote system and references to resulting Virus.As I am writing this review, I have Lenovo the Atlanta Georgia phone support office on the phone and for the past 45 minutes they have been unable to assist me. I did inform the Lenovo Rep that I am posting my reviews about my ongoing customer experience and I am here to let readers know I am still on the phone and Lenovo seems to 'couldn't care less' about my Lenovo problem. There continues to be no effort to resolve or remedy the situation.In summary in my experience and in my opinion do not buy Lenovo products.
