In a lot of our reviews of TVs, we tend to recommend buying a separate audio system because of their inadequate sound capabilities.

Good; Easy to set up and use; Decent mid-range and low-end sound; Can get quite loud; Support for Dolby Atmos; DTS:X; 4K passthrough; HDMI-CEC; Fairly wide soundstage
Bad; Vertical Surround mode is gimmicky; No display; confusing LED-based prompts
