Where the heck did you find find that you you da man ! You have secret link or list somewhere panelook didn't have anything on that panel wouldn't be the first time Sony put a SPVA4 6-bit + FRC panel in a set .
@ andy sullivan
On last years sets with this kind of panel (smaller also ) The colors are usually radioactive or neon looking on some of the of the pre sets and they push red and blue badly sometimes until you fix it sometimes ofc that's the set on the red push I think, just set it to neut color temp it takes care of that without pushing blue . My 2013 R4 (similar panel ) was terrible out of the box .
I believe last years 70 R5 Bravia used a Sharp ASV panel AFAIK
total different panel this one might be better once it is set up. it depends on a couple of things though so it could go either way .
I believe these panels like to dither aimlessly more than usual if they don't get fed enough chroma bits and it can make some stuff like dark back grounds look veiled or foggy but a lot of sets are like that anyway .
As long as it's making colors (or B/W ) from a decent signal it's fine good as most 8 bits better than quite a few of them IMO. at least on the smaller panels I have not seen the 70 yet at lest we know where Sony is cutting costs .
P.Q. depends a lot on the black level and the contrast especially not having the picture enhancement work around you would find in a Sony 9x /9.5x or FALD Sony .
If B/L ,contrast are good like the smaller ones its usually much better than an 8 bit panel with less black and contrast as a rule .
I have the 2013 40R4 with one like this set up right it spanks most any other 40 out there including a 5x 6x Sammy ,the FALD Vizio and a lot of bigger sets better color and picture detail but it took me a while to get it that way because what you have to do might not align with conventional wisdom it wont won't spank my larger PDP but not too many LCD will .
and all the reviewers got it wrong
except one in the UK but I saw that after I figured mine out
I was pissed when I found out my set had a 6 bit +high FRC panel at first until I figured out how to set it and the excellent contrast and black levels it has in my case . As it turned out in the end it really was not an issue partly because of the contrast and blacks on this panel .
Also when I read how these new ones work these will actually make 8 bit color just fine all of it
not like the older ones on PC or maybe older TV that were crappy . New ones have modern advances in the dithering algorithms and faster sample and hold times and switching circuits in the panel drivers it's pretty clever how they do it actually . They are doing that with some 8 bit panels in 4 K sets now to make 10 bit color that you would think requires a 10 bit panel Samsung seems to have this down pretty good . .
Most Sony are much more accurate in Cinema mode but you have to turn up the backight and contrast the Cinema mode the defaults are way low the Cinema mode, gamma pre set should be spot on in Cinema mode . .
Set them up right and feed them a good signal and they play pretty well as well as many 8 bit panels and better than quite a few . (ofc that is assuming the 70" panel has good black and contrast
like last years smaller Samsung panels in the smaller Bravias if it does it's fixable otherwise toss it ☺☺☺☺
Best thing to balance (fine tune ) color saturation and brightness is this Sony color blind test they have a video and some images do like it says and you will be good and not over saturated like all the pre sets its very clever and it works well
you can play it on a stick and set it globally if you have that option or what I would do is set it with the stick or play it or steam it to the set from a PC and copy the settings to the other modes ( I think downloading the actual files to a stick are better because browsers render color differently most of the time )also maybe crank up the brights 5 pts in game and general mode
Sony Color blind Tests
Short of a decent full on calibration I would peg the back light and Contrast in both of the cinema modes or any mode actually watch your color saturation and turn off any blinking back light business auto brightness and Eco stuff if present best picture is in Cinema mode if you have 2 use 1 for day and 2 for night and knock the brightness down 5 pts at night for black level goodness .
On a pattern or disc set brightness to reference black (just so know where it is ) because you will have to bring it up anyway to get adequate illumination, the trick is not to bring it up so far that it clips whites or washes out blacks or to low where it crushes blacks and shadow detail it takes some time to find the sweet spot and 5 pts either way can affect it more than you would think under some conditions . my brights are perfect at 50 night and 55-59 day depending
most calibrations published were close to that but they totally missed the most important cinema mode thing
and used general instead ( doesn't sent fly well on my set ) one of the better and very good UK sites got it right I like them better than Cnet .
Do it right and the picture might surprise you. . Out of the box pre sets sometimes will make you want to send them back long as it has good blacks and contrast like the smaller ones they can spank a lot of 8 bit panels (if they are set up right ....if not you might not get good results . ofc if it has poor blacks and contrast your'e fighting a loosing battle .
OH Important set pixels at 1:1 or Full pixel
auto display area off 4:3 default off if you overcan /underscan by as little as 2-3% you could loose half of your resolution and not even know it not a good thing on a big panel color temp should be neutral otherwise colors will be skewed neon green lawns and lavender blues sometimes but when they are set right
(if the 70 is like the smaller ones ) they can be sleepers .
I suspect all the W600 sets are like this because they use Samsung panels ,Most of the of the 8x/8.5 Sonys
use AUO MVA panels unknown 2 Me if 8 bit or not 84" 9.5x used an CMO innolux pamel
W600 are getting very favorable reviews in that market as are the 8x/8.5x within their market.
Maybe these are Samsung cells with Foxconn fabricated and installed back lights like some of the other ones
would be interesting to see at least the contrast spec they might have a 10 bit signal interface but I think they overdrive it in 8 bit mode for the most part surprisingly when the smaller ones are set up right you would never know it was a 6 bit + high FRC panel at all except it doesn't like to make Cyan without adding in some extra blue not an issue you would notice in normal viewing a lot of sets are like that whatever panel they have .
