Hello Dupa, 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. IAlso, to make sure you’re getting the most out of you VIZIO TV, we’d recommend making sure your devices are connected with an HDMI cable, and are set to broadcast in 4K (2160p) or Full HD (1080p). You can also individually adjust your picture settings in the menu. For brighter rooms try using the ‘Calibrated’ setting, for darker rooms try ‘Calibrated Dark’. If you’d like any help adjusting your audio or picture settings feel free to contact VIZIO support at 855-833-3221.
