There was an era, not too long ago, when Vizio was the reigning king of budget TVs in the US. In this guide I'll explain what ACR does, why it's so terrible, and how you can shut it off quickly. The companies that subsidize TVs with ACR often mask it with euphemisms like the one I mentioned up top, making it easy to turn on by accident, and harder to turn off. In the case of Vizio TVs, be sure to reject Viewing Data during the initial setup process. Highlight Viewing Data without clicking it.
