Vizio sold me a TV with a defective module for 4k@60 on June 8th 2016, through Amazon. I could not have known of the defect while under warranty as I owned no device that supported 4k@60hz. Now that I've learned about it they won't do anything for me. This company is now refusing to take responsibility. This looks very bad for you indeed. This is -deceptive advertising-.
