Dolby Vision was launched at CES at the start of the year, promising to deliver another leap in TV picture performance, thanks to an expanded colour palette, enhanced dynamic range, and dramatically increased contrast ratio. Now we have the first Dolby Vision televisions - at least in the US. Vizio is the brand responsible, a US consumer electronics company that's known over the pond for its affordable 4K TVs. The new Dolby TV tech will be on the Vizio Reference Series range (pictured, above), which features a 65in and a 120in 4K Ultra HD model (and is not so affordable).
One is that DTS signals were downconverted to stereo PCM by every TV. So even in the best case scenario, TVs will downconvert surround sound to stereo for movies that only include a DTS soundtrack. We also found that regardless of the type of Dolby soundtrack, pass-through was always limited to Dolby 5.1/48kHz.f you're looking for a TV that can pass a true 5.1 signal, then based on our results you'd be smart to stick to Sony, Toshiba, and Vizio models. Regardless of cost, all of the televisions from these three manufacturers that we examined were able to pass-through Dolby Digital 5.1 signals via their optical output.
