Returned my P65
I purchased a P65 from BB a couple weeks back, and just returned it yesterday. I lost sync between the TV and the tablet a few times and it took a different procedure every time to get it back, each time taking at least an hour of rebooting, resetting, reinstalling, etc. This was running the latest firmware and all updates to the tablet that install when you 1st bring it up. Also, this TV had some weird issues with judder as well. I would randomly experience motion issues that would sort of come and go despite whatever settings I tried. When it was having these judder issues, I could consistently reproduce them using DVRed content, when they would fix themselves, watching the same DVRed content would have no issues at all.
I am sorry that I had to do this. When everything worked, the picture quality was really nice, and I really do believe that casting and Dolby Vision are what will be standard for all TVs in the next few years. My brief experience with this TV resulted in just too many issues to justify such a large purchase and a sort of gamble that I would be able to work with Vizio support to get it working correctly was too much for me to take on.
Best of luck to those that are still experiencing issues, and I hope you all get your HDR10 update soon!
