Update on the 1.60 Update
As I've mentioned before, I have 4 of the 2013 M-Series sets thanks to mother nature and lightning. I have a 65" and a 70" that were purchased on 11/22/2013, a 40" that was purchased on 1/30/2014 and a 47" purchased on 4/27/2014; All from Costco.
I've been in high tech for almost 40 years now. I agree with whomever mentioned differences with product within a model series. I've seen it cost some rather large Companies a significant share of wallet by not standardizing their component supply chains sufficiently and using "supposedly" the same component from multiple vendors through a long term production run only to find that they ended up supporting multiple revisions of firmware because of tolerances amongst the build parts. You try to convince a Fortune 100 IT department that it needs to use serial numbers and not model numbers when it comes to applying patches/updates. That said, it costs more to secure that supply chain and thus you must charge more. All trade offs. I guess that's a long way to say, there is validity to certain builds behaving differently and I suspect Vizio has figured this out.
I've received the update to 1.60 for the 40", the 47", and the 70". The 65" is in the Family Room and is on quite a bit. That's the only explanation I have for it having not yet received 1.60 for that set.
For all 3 sets with 1.60, my Picture Mode was changed to one of the presets as a result of the update. In all cases I selected "Calibrated Dark" to begin my "tuning" and then saved my settings to a new Custom Profile.
In all cases, I've been able to set Smart Dimming to OFF, "calibrate some items", and SAVE the new settings to a NEW custom profile. I then powered down the set(s) and observed that Smart Dimming remained OFF through multiple power OFF/ON cycles.
Last night I unplugged all 3 of the updated sets to see if there was anything that may be connected with a complete power cycle. This morning I powered them all up and Smart Dimming was still set to off. I also do not see the "flash to bright" being mentioned on any of the sets but I will admit, I have NOT really looked for it. Besides, if as reported it is a 1-2 second temporary item and the picture rapidly stabilizes to the intended settings, I don't really care.
For complete background, all three of these sets are connected to the same source as follows. All other connected sources not mentioned on the various switches are capable of the same resolutions and display capabilities (except for 3D of the 70; when I want to watch 3D I power down the first 1x4 switch and re-negotiate). Another way to put this is the lowest common denominator would be the 40 for purposes of HDMI handshake negotiations.
- DTV HR24-100 -> 3' HDMI cable -> Yamaha RXA1020 (pass-thru enabled)
- -> Yamaha RXA1020 (HDMI out 1, processing enabled to 1080P) -> 6' HDMI -> 70"
- -> Yamaha RXA1020 (HDMI out 2)
- -> 6' HDMI cable -> 1x4 HDMI Splitter/equalizer/amplifier
- -> 30' HDMI -> 40"
- -> 25' HDMI -> Monoprice 1x4 HDMI over CAT5E/6 (75') -> 47"
Additionally, all my sets are connected via WiFi to a separate AP on a separate channel from the AP I use for my computers and all my sets have the WiFi remote enabled (much earlier in this thread I mentioned it was an important feature for my use). This separate AP keeps any/all "interference" from my normal and allows for me to easily keep the WiFi remotes functioning while isolating the sets from the internet.
