The most common scenario for this is on a scene with a bright sky with a lot of dark horses/shadowed faces on the bottom. The beard of the main focus will get what appears to be groupings of stuck on pixels. Its somewhat rare and not terribly distracting. (This is using settings similar to the OP Calibrated Dark).
I like the direction of the tablet/casting methodology to control the TV. I think this TV was rushed to market when much more testing and refinement is needed in this aspect. I expect some device combinations to have issues. I couldn't expect them to account for every device out there. But these are core features with the provided hardware that aren't functioning properly. Maybe others have had smooth experiences with casting and never run into these issues I've seen? Otherwise for the average user the TV is going to be a frustrating experience as they try to work through these issues. I wouldn't expect there to be much difference and I don't have enough usage for a good comparison but it did seem like casting from my own tablet device was more successful than using the one provided with the set.
Thanks for the detailed overview. It's important to get this stuff on the table.
I will say that I've been very stable since .12 firmware and updates to all the apps. Not perfect, but very good.
YouTube is glitchy. 4k stuttering is an issue.
Download speed reported by Vizio's internal test app is inaccurate. This is well known. It doesn't resolve your network issues though. Are you connected via ethernet or wireless? Hardwire is best if it's possible.
The only way your internet connections on the M would have shown the names of connected devices is if you had HDMI CEC on. Is it enable on your P series? Do you really want it on?
The tablet as a sole device to operate your home theater needs some advancement. You make valid points.
In summary, hardwire your internet, update the firmware and all apps on the table. Do a full reset of the TV. I think it will improve. Some things need updates (YouTube, tablet function). The TV looks amazing when using for 4k/DV and high quality bluray and cable sources.
