I've been monitoring this thread, and I contacted Vizio to get answers to some of the questions that have been raised. In no particular order:
- The LCD panel in the P50 has a native refresh rate of 60 Hz; all the others are 120 Hz.
- The 2016 P-Series does not have an internal OTA tuner, so by FCC definition, it cannot be considered a "TV" per se. Instead, Vizio is calling it a "Home Theater Display," but it could also be called a video monitor, like the last-generation Pioneer Kuro.
- The S/PDIF optical output can send 5.1 Dolby Digital and DTS bitstreams as well as 2-channel PCM from the display's own apps and from external devices.
- The P-Series supports Audio Return Channel (ARC) via HDMI with the same capabilities as S/PDIF—that is, 5.1 Dolby Digital and DTS bitstreams as well as 2-channel PCM.
- Because of the "cold war" between Google and Amazon, the P-Series cannot stream content from Amazon until something changes in the relationship between those two tech giants. The P-series is essentially a Google device—in fact, the first Google Cast device to support 4K—and Amazon won't allow its content to be streamed to any Google device. For more on this, check out this article
, which is admittedly over a year old, but I don't think things have changed radically since then.
- The P-Series can stream 4K content from YouTube.
- The tablet remote communicates with the display via Wi-Fi or Bluetooth if Wi-Fi is unavailable. The secondary remote communicates via IR with the basic commands for power on/off, volume up/down, mute, etc. A universal IR remote such as the Logitech Harmony can be used for these functions, but the tablet or other Android or iOS device is required to adjust the picture controls etc.
- The display has an OSD for volume and a couple of other functions, but it does not have a full menu system, which can be seen only on the tablet or other Android or iOS device.
- The P-Series display incorporates an octa-core processor with a quad-core GPU and quad-core CPU. Regarding the tablet's processor, my contact said it has "a fast processor so that it can search the web, stream content (to itself), display video, and perform other functions."
