Hello SK allday, sorry to hear you are not having a smooth experience. I would love the opportunity to have our technical support team learn more about the issues you are experiencing. Typically these issues can be resolved by power cycling the TV where we will unplug the TV's power and then hold the power button on back of TV for 5 seconds or leave it unplugged for at least a minute. When you have a free moment, our technical support team is available through text message, chat, or over the phone. Just go to support.VIZIO.com and click on ‘Contact Us’.

Hello Mark01, 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, and our new line of Atmos Sound Bars.
