Just bought the TV from Sam’s club, online. The audio issue that a lot of people are complaining about happens to me too. Tried changing pretty much all the audio options on the TV. The issue persists with the TVs on board speakers, and on a sound bar. I’m open to suggestions. But I’m pretty sure I’m just going to return it. Not to mention the brand new TV has trouble turning on some times. Just shows a black screen after I unplug it, to cycle the power to try and fix the choppy audio. And the TV has what looks like a finger print on the bottom right of the screen in glue that I can’t get off. So, needless to say… I’m not very happy with vizio’s quality control. The magenta hue is definitely noticeable, pre calibration. Never got around to post calibration given my other more serious issues with this TV. Other than all that though, the picture is really nice. I’m also open to suggestions for a different tv in this price range. Got this on sale for $440 for the 55 inch. I’m thinking the TCL 5 series. I mostly care about good picture, low input lag, 60HZ, and 4K HDR.
