Hello Lore, from your review I am not sure what may not be working with your SmartCast menu. We’d really love the opportunity to have our tech support team run through some troubleshooting steps to see if we can get the TV up and running for you. When you have a free moment, they’re available through text message, chat, or over the phone. Just go to support.VIZIO.com and click on ‘Contact Us’.

Hi Sbdm, thank you for leaving a review. As televisions continue to have larger screens with thinner profiles and sleeker bezels, there is less room for large speakers. To help get the best audio quality out of your VIZIO televisions speakers, we’ve included settings like DTS Studio Sound to provide the highest performance possible, while maintaining the thin, sleek, bezel-less profile of your television. If you’d like any help adjusting your audio settings feel free to contact VIZIO support at 844-254-8087. For top of the line audio performance you may also look into purchasing a VIZIO Sound Bar, there are several models available with wireless subwoofers for enhanced bass, rear speakers for true surround sound.
