The Vizio P-Series Home Theater Display is a bit unorthodox when compared to other 4K HDTVs in that it ships with a fully-functional 6" Android tablet. Instead of Android TV or other visual UI with apps, the Vizio P-Series Display is built entirely around Google Cast and requires you to cast all your content over to it. The reason it is called a 'Home Theater Display' and not an 'HDTV' is because it does not feature a TV tuner built-in. Some specs worth noting that will be covered in detail in our full review include the Ultra HD (3840x2160) resolution, Dolby Vision High Dynamic Range support, 5 HDMI ports, Bluetooth, and 126 local dimming modes.
