when you enable ACE it cuts the whites in the midtones and makes them brighter but you loose dynamic range in the picture.

Well, you are using Scene mode "General>Standard", not "Cinema". That makes a difference!

From my experience, the filters used in "Black Corrector" and "Adv. Contrast Enhancer" are always active in scene mode General. I found that when I try to "match" the picture between Standard/Custom and Cinema, and having both BlackCorr and AdvCE off in Standard/Custom, then I need to set both options to MEDIUM in Cinema to get a rough match between the scene modes. This means, the other way round, one of the main differences to mode "Cinema" is that you always have BlackCorrector and AdvCE filtering in Standard/Expert. It cannot really be switched off in those modes.

Compare the graph in the middle of this post. (External link, german "hifi-forum")

the cimena mode with the same settings as general/standard looks worse
dont you see it for your self?

as for the adv.Contrast Enhancer
IF it had been active all the time in scene mode General i would have seen it when i measured the gamma cuve with my colormeter.
it isnt active because the gamma curve is flat.

ACE screws up the gamma curve and you will see it directly if its on or off.

i have not measured the cinema mode and the standard mode with the same settings but i can do it.
i post the results later

Rarely will two different picture profiles require the same settings to produce optimal results.

Try to run a completely new calibration in Cinema and see what kind of results you can achieve. To my eyes, a Cinema profile that I had merely tweaked blew Standard away. Then again, accuracy and personal preference may diverge for some, so you're free to enjoy your television any way you'd like.

ok more measurements

you get different light outputs with different "Motionflow" settings.
here they are
(no other setting changed but motionflow)

Clear: 191 cd/m2
Standard: 228cd/m2
Smooth: 228cd/m2
Off: 228cd/m2
True Cinema: 228cd/m2
Imulse: 72cd/m2
Clear Plus: 142cd/m2

"Looks worse" is not exactly a scientific statement. smile.gif
- In which way worse? If you mean s-th like "less punchy", then ... yes, that could very well be. Standard/Custom does have "more punch". And now, guess why that is? (Start with thinking about for what technical reasons that possibly can be.) wink.gif

I'm not sure in how far a gamma curve screwed by adaptive filtering can be seen in standard measuring. Means, this will depend on how the pictures for measuring are designed. What I would do if I had measuring equippment (I don't have) is: measure i.e. an IRE20 patch that is surrounded by IRE0 or IRE10, and measure an IRE20 patch that is surrounded by IRE80 or IRE100, and measure a screen that is all flat IRE20. My bet is that those readings of IRE20 will be noticeably different, when using picture mode standard or custom.

* * * * *

A common-sense approch without measuring equippment:
- All settings equal, (and BC + ACE both "off"), the picture modes "standard" and "cinema" look quite different
- keeping BC+ACE off for Standard, but setting them to low or medium for Cinema, "Cinema" becomes looking much more similar to "Standard".

The conclusion of this behaviour is quite obvious.

i have done measurements with the same settings in both GENERAL/STANDARD and CINEMA modes

the only thing that the Cinema mode changes is the gamma curve
and it changes it to the worse
i have checked 2 times and got the same result on both

minor changes in the color saturation between the both modes

the cinema mode lowers the gamma curve in the high tones around IRE90
Use STANDARD mode to get the best gamma curve from this tv










The last test was with Adv:Contrast Enhancer set to MEDIUM (the other settings was the same on both modes)
ACE beaves different so i suggest if you must use it
use it with the CINEMA MODE.

yes they do
just as i have measured you get more washed out whites with cinema mode.

other than that you seems to get a tad more saturation in Standard mode
you can see it in the Luminance chart for the Blue and Magenta color.

im switching between them just now with the movie Oblivion
look at the clouds at 2:13min

Hi All,
I just purchased the W900A directly from Sony, and on noticed the backlight is uneven along the edges. I tried to capture the problem in photos, but it's a bit hard to see... You may have to squint a bit biggrin.gif. Anyhow, i haven't seen anyone else posting about this problem. Am I the only one? Do I exchange the the TV? Thanks!

The first two images are AVS "inspired" test patterns from YouTube. I don't know how authentic they are, specially when compressed via uploading to YouTube, I just needed any video with a full clean white background.

Incorrect -- as you can measurably verify. Again, calibrating one picture profile and then carrying over those settings to another profile does not produce the optimum picture for the latter and subjective tastes may not correlate with standardized accuracy.

An aside, but your peak light output is obscenely high. eek.gif

I just got this TV not long ago and was wondering what is the best calibrating settings there is for a movie, sports, and tv shows? I'm trying to do some research on my end as well, but I'm coming up short.

it gives a great contrast
this backlight system works so well so you can crank it up sky high without getting Blooming/Clouding/Halos you name it smile.gif
just a razor sharp bright image

thats with backlight at 6
max peak light is 301cd/m2
slight lower with the "Clear" motionflow setting

The w900a does have darker edges, but that is extreme. It should be hardly noticeable unless you are really looking for it, and it should only be possible to see on bright images.

from an old Pioneer Kuro Demo smile.gif
backlight at 8
that should be around 250cd/m2 peak brightness

unless your monitor is at 250cd/m2 its hard to see the brightness
its bright.
those fireworks lighten up the room completely

I've tried your set up and at time's it is good, but sometimes the picture is still blurry.

for material with low noise you can turn OFF these
NOISE REDUCTION: MEDIUM
MPEG NOISE REDUCTION: MEDIUM

that makes the image sharper

Edit: i have change my settings above
after some more testing i find that those two noise reductions is overkill and not needed.
they only blurs out the picture.

Do the graphics suck on madden 25 and ncaa footall 14 or am I just used to playing my 360 on a smaller tv. Also in diablo 3 the characters look a bit low res, probably didn't notice it as much on a smaller tv.

I just bought a sound bar and was wondering if there are any other options I can tweak to make the image better since I now have sound playing elsewhere?

sorry i dont understand what you mean.
what has sound to do with picture settings?
if your picture isnt good with my settings it must be the source material or something else that is bad.


i need to praise the "Blue" backlight with its Quantum Dots on this tv even more! smile.gif
im now using 8 in backlight and that is crazy high for a room with only 4cd/m2 ambient light( 3 40watts Lamps)
normal LCDs cant handle this high light output but this tv has no problems with that.
it ONLY adds even more contrast and brightness to the picture.
no sideeffects!


test my settings with backlight of 8 instead of 6 and start the movie Oblivion.
then you must agree that the picture you are seeing has the highest contrast ratio you have ever seen.
you can almost feel the burn from the sun in the beginning cool.gif
just like you are there.

crazy but so damn good smile.gif
230cd/m2 peak brightness in a dark lit room

Only thing I see different off the Sony website is the the new 65" W850 uses Motionflow 480 vs 960. Although, it still retains the Triluminos display of the W900. Hopefully the input lag time remains the same for gaming use.

Why is this? Makes no sense. Is the W850 still a 240hz panel?

Why do you say its matte? The 900a is reflective like a mirror in the day, but that also contributes to the contrast. But you need some dark curtains during daytime. At this point the W850 is a big unknown. I am returning my W900a. Sony gives you 30 days to return it after you get the RMA. I waited until the 29th day to get the RMA, knowing about the W850. I'm certainly waiting to get feedback on it before buying it.

The motion flow 960 vs 480 is a gimmick. I feel that Sony made the w850a motion flow 480 to keep it "technically" under the w900a to keep the current w900a owners happy. In other words, if they had made an exact 65" version of the current w900a common folk would be angry knowing its in the same price range. It may even be possible to flash the w850a with w900a firmware and have yourself a 65" w900a.

Also, the screen is glossy on the w850 not matte.

I've found the following to be a great baseline setting: http://www.hometheater.com/content/sony-kdl-55w900a-3d-lcd-hdtv-settings

I bumped the Sharpness up to 50, and tweaked the Backlight, Motionflow, and ACE to taste. Most pro review sites leave all Noise Reduction option off.
