When I arrived & wanted to use Netflix, I found out that I had to sign in; which I then did with my Netflix account. I then saw that this particular tv needed a mouse to scroll through Netflix (the remote had limited functionality). I have the same tv in one of my rooms at home. The receiver, for the wireless mouse that comes with the tv when you purchase the tv, was in the USB port on the tv. The more that I am trying to explain to Liz that a mouse is needed to scroll through Netflix, the more she is telling me that I am using the remote wrong. She sent another guest (as she puts it, to show me how the remote works). He could not scroll with the remote. I went & purchased a wireless mouse to show them how it works with the mouse because Liz said that Sandra would come around the next morning. The next morning Sandra came with the mouse that comes with the tv & we could scroll through Netflix with the mouse; bit even then Liz still insisted that you can scroll with the remote (which you can't) & still insisted that I did not know how to use the remote for Netflix. I've been using Netflix for over 15 years. If Liz had just told me that the mouse was not there & that they would bring it the next day, I would have accepted that but she kept on saying that I did not know how to use it. It's really frustrating dealing with someone who has no idea what they're talking about but will not listen to anyone when they're trying to correct them.
