Are you talking about user adjustments or CMS calibration settings and do you otherwise know the difference ?
ofc there are some sets that have none Sony has a few models like that now that does not necessarily preclude them from benefiting from a calibration however .
Adjusting the set as you say to look brighter would intuitively mean adjusting the brightness and maybe contrast and or backlight no ? Wouldn't be hard to store a day night mode would it Why the persistent narrative changes and straw man arguments ? these things do not support your positions .
I prefer to let the TV adjust itself for changes in ambient room lighting.
Again if you prefer to let the TV adjust itself that's fine just don't expect that others should share that preference
or believe in meta data fairies .
In addition, if you calibrate that TV Cnet style from the general custom mode, all the other scene modes are modified in ways that are unknown to anyone unless you write them all the settings down for pre-calibration documentation. It would take a good 8 hours of work to do that documentation.
Palmer wrote in an earlier post here
"As far as scene mode settings are concerned, calibration in one scene mode does not transfer to any other scene mode. You have to do a manual entry of settings in each scene mode, or do a new calibration."
^^^Maybe some contradiction above there ?
NO it wouldn't unless you write awfully slow ........didn't you say earlier that calibration in one scene mode does not affect another mode sure you did.
SRSLY and I shouldn't have to be the one to tell you this but you need to check your earlier posts so you don't contradict and embarrass yourself (again )
OTOH calibration *may affect the other modes possibly if you enable global changes on *some models and brands that allow for that.
OTOH each mode (user adjustments ) should be easy to be reset to defaults .
The only change Cnet made to the custom setup for calibration purposes was to activate the LED dynamic control (plus standard calibration required changes to white balance). All other settings were left as is except for the change from "this" input to "all" inputs.
Re tube twister
Some sets need less adjustments to measure well and look well than others nothing unusual about that no?
Today I just noticed another peculiarity in my TV aside from the fact that my specific TV does in fact change scene modes based on Rovi data if the scene mode is left in auto scene mode.
Re tube twister
It may be changing scene modes but probably not from Rovi data but more likely from it's own algorithms
and or EDID data and what it sees (frame analysis) you are assuming a lot there .

Your's TV ain't only thing peculiar around here !

If I select the Cinema mode (Cinema -1 subset) to watch a movie on broadcast TV, there is one set of settings used by the TV in Cinema-1. If I watch a DVD or Bluray in my Sony Bluray player, the Cinema-1 settings change without user intervention. You can change the settings, but if you power down the player and start the Bluray player again the Cinema-1 settings return to the Bluray player defined settings.
More commonly known as EDID and an HDMI "handshake "
You would willing to make a bet without knowing the qualifications and experience of the person you are betting against?
Re/ Tube Twister
Palmer ...........didn't you just say "I prefer to let the TV adjust itself for changes in ambient room lighting." make up your mind you can't have it both ways .
Re/ Tube Twister
Yea there is some funny stuff being bandied around here that's for sure !
Again if you prefer to let the TV adjust itself that's fine just don't take positions you can't support and denigrate
others positions and or or professions especially while not providing any legitimate support for your positions ofc someone will call you out did you expect otherwise as long as you have been posting at AVS I would have thought you would know that .
Nobody' making straw man arguments here or changing the narratives (well almost nobody ) we expect things stated as facts to be supported or at least in some way supportable that's not unreasonable !
I read the Rovi links they are all about advertising and guides nothing to do with picture quality ZERO you still have not provided any verifiable arguments that your TV uses Rovi to set or adjust picture quality the fact tour TV waits for something to set auto mode still points to the fact it is more likely looking at frames and any EDID data present before changing anything until you can prove otherwise your credibility is ZERO sorry that's how it goes when you state something as fact here that can not be supported .
Even allowing for a HUGE benefit of doubt here as I was so kind to do earlier on and imagine the TV did something with metadata other than a channel guide or something like that even after some study the fact it won't invoke Auto Mode until it see's some Rovi data (maybe it could just as well be looking at frames also and waiting for that) it is still rather incomprehensible (again ) after some reasearch to think that has anything to do with picture quality but at best is just for a channel guide or on screen channel and show title display banner .
If you are going to continue to hijack this tread at least stick your original argument don't change the narrative like c net calibrations and other posts in other threads unless it supports your argument and do provide some verifiable support of your positions (it's called free discussion ) do your research see if you can find a use patent or something .
I did some of your homework already early on and could find nothing to support any of your positions although I tried to be more than fair until the nonsense you've been posting compounded and further made it apparent that whatever you think you know has thus far has not supported any of your positions or contributed anything useful to the discussion .
TBH and I hate to have to be the one say this ... but quite frankly there are more than a few of us here probably about ready to push the ignore palmer button the fact that you can not see that by now perhaps points to some clinically diagnosable issues . ....I really hate to be the one to tell you this also and I'm only trying to be helpful but .........FWIW If it were me I would maybe see someone about that just saying.
You are babbling a bit again. You can't distinguish what the Cnet calibration did as compared with letting the TV do what it does.
1. Cnet chose a one size fits all calibration. They set the mode to custom, inputs to "all" with the unintentional result of seemingly random changes to different scene modes.
I do not use the "all" setting for inputs, I use "this" input setting. The difference is major. When you use the "this" input, the specific changes you make are limited to the the scene mode that you are in.
Here are some of the options that are available in each scene mode. Cnet does not use any scene mode, they use custom. No options is standard for custom, and Cnet only chose the optional LED Dynamic Control in their calibration routine. By using the custom mode and setting it to "all" they screw up the other scene mode settings without knowing that they were doing so.
I tried the Cnet method. It screwed up my scene mode setting so bad I had no clue on what was normal, so I had to do a complete reset back to factory (6 resets per scene mode).
It is still my opinion that the Cinema mode is the proper mode to calibrate to.
"Cinema - For film-based content. Suitable in a theater-like environment."
Some detail here:
2. This will be the last time I say this. As far as scene select is concerned, Sony does use the Rovi TVGOS data to select the scene mode. I did turn Rovi off and let the Rovi program data base that was downloaded into the TV expire. I then used the broadcast data stream for program information. Auto select scene mode does not work because the Sony TV does not know what genre tag the program should have. That is what Rovi does - they tag each TV program in their metadata downloads. Wrong Rovi tag, then auto select will select the wrong scene mode. No Rovi tag, then the default mode is used (AKA no scene mode is selected).
Does the Rovi Guide work on off air broadcasts? Not as of Aprtil 2013 when the Rovi data insertion equipment was removed from the ATSC broadcast systems.
Does the Rovi guide work on cable? Not via the HDMI connection in a cable box, and maybe not at all even with a direct connection from the cable company to the TV depending on the cable company.
How does the Rovi Guide get it's metadata these days? Via an internet connection.
If Rovi ever stops providing their metadata to the internet, will the Sony auto scene select work? No!
No matter what you "professionals" say about the entire matter, that is just the way it is!
