Another positive after updating to v727 from v715 is dynamic tone mapping not switching from off to on on its own.After using V727 for about a week here is my experience:
1) Audio synch for me much better! Using Auto digital out to a Samsung Q600A soundbar. Audio synch was driving me crazy before and now I can live with it.
2) Now finding and playing Netflix movies that have Dolby Atmos. I was not seeing or playing Atmos on Netflix before update.
3). Picture quality I would rate better now than before update.
4). I think there are more options in Settings now.
1). CEC not always working, especially on startup. Have to stop and restart CEC for it to work after cold boot.
2). On cold boot goes to TCL home page not last input used. Works fine on warm boots though.
You never download before....?
You can try V727, even is not native version.Hello!
Is Is V8-R851T02-LF1V727 the latest version that is safe to OTA flash to TCL TV model 75S434? (I originally posted here with my hardware/software details. I apologize if crosspost is in bad form, but that other thread tops Google results so I hope it can help direct future users to the right information.)
