I purchased this for work but am selling it as I haven't used it. When using the touch panel, please connect it with a Type-C cable. I have been storing this for a while, so I tested its operation. Sound also came out from the monitor's speakers. The touch panel also worked. I took a video, but it seems I can't upload it, so I've included still images of the process in the second image. Please only purchase if you are able to set it up and use it yourself. I am also listing this elsewhere, so please forgive me if it sells out.
