Vizio has announced that it has started rolling out a new firmware update for the company’s SmartCast P-Series and M-Series 4K TVs that enables support for the HDR10 specification. That is very important for the few people who currently own a 4K Blu-ray player or, just recently, the Xbox One S. Now, Vizio’s SmartCast TVs are capable of displaying those HDR 4K Blu-rays in full high definition – and that high dynamic range does add more to the viewing experience over the boost in resolution that regular 4K gets you.
Since those Ultra HD Blu-rays are still in their infancy, Vizio is also talking up the growing catalog of Dolby Vision titles available for rental and purchase from Vudu. Vizio is also quick to remind users that it views Dolby Vision as the superior option.
HDR10 is based on the Rec2020 color space format but restricted to a P3 color space and a maximum of 1000 Nits in a 10-bit format. Dolby Vision is a theatrical format, featuring the Rec2020 color space but capable of offering up to a 12-bit format. Where the HDR10 standard is limited, Dolby Vision content is mastered in Rec2020 and boasts 4000 Nits with the potential to expand even further for more finely-tuned dynamic content.
Either way, having a TV that supports both HDR specifications is definitely one reason for picking Vizio over some other sets. But remember that this only applies to the P and M models; the lower M-Series SmartCast TVs aren’t compatible with either Dolby Vision or HDR10. Your SmartCast TV should automatically install the update if it’s connected to the internet. From there, “open the VIZIO SmartCast remote control app, tap Settings and press Inputs, then HDMI Color Subsampling, and then enable subsampling for the HDMI port the HDR-enabled Blu-ray player is connected to.”
