Lenovo USB Soundbar Speaker for Lenovo Monitor

Hi Claude, We cannot determine compatibility with the information provided. The 40.7U... number shared represents a European structural engineering standard identifier, which is not something that can be used to help identify the monitor in question. Please post another question and include the model number of the monitor (should start with two numbers, followed by a letter, then another number. Example: 68F0) in question, so that we can assist you more precisely. To note, we also wish to share that this soundbar speaker was designed to be mounted to and work with certain Lenovo ThinkVision monitors. We look forward to hearing from you, and feel free to reach out to us with any other questions!
