For now I want to say that it definitely has got dse, banding and some clouding at corners. If it wasn’t for the price of 1200$, I would probably return it.
Viewing angle is very limited and you really have to sit directly in front of it, move 30 - 40 cm to the side and you get lighter blacks on the opposite side of tv.

What really made me happy about this TV is it’s impulse mode and low input lag, compared to my old Mitsubishi 930sb crt monitor it’s almost as fast.

I have compared this 55w905a side by side to other 4 display devices I've currently got: Mitsubishi 930sb CRT monitor, Benq gw2760hs a-mva monitor, Samsung 40b530 spva tv, Samsung 40eh5300 spva tv.

And after comparison I'm not happy with this Sony TV color reproduction.
Green color at 100% saturation is obviously not fully saturated. If you turn live color to low, it becomes fully saturated, but much shifted towards blue, which makes grass look a little unnatural.
Blue is undersaturated just a bit but it's hard to notice.

But what really disappointed me is Yellow!! It is definetly undersaturated too much, and nothing can help it. I've tried changing every single option in the menu in every mode. Even increasing color setting to the max did nothing to it.
I've even got into service menu and tried to change white balance, no luck.
All my other display devices displayed good saturated yellow.
I've added photo comparison to Benq gw2760hs va monitor(it's to the left with 55w905a to the right).

All I've said about colors can be seen in hdtvtest review, except yellow undersaturation looks much more dramatic than seen on their color scale.

It is very disappointing that a TV priced 3000$(when sales began) and having this widely advertised Triluminous tech actually can't reproduce colors as good as cheap old Samsung 40eh5300 spva tv (400$).

Does anybody know a way to fix this undersaturated yellow issue? maybe there is some setting in service menu I haven't found?
Does updating firmware change color reproduction in any way?

For now I think that it just can't reproduce saturated yellow due to this Triluminous tech.

First the undersaturated yellow your seeing is not the fault of the Triluminous tech. You paid $1200? I agree with turnbowm I'm also guessing it was an open box item. My W900 dosent have undersaturated yellows so what I am thinking it may be the settings your using or something may be wrong with the tv itself I have no clue. But what I do know is again its not the Triluminous techs fault that your seeing the yellows you are. Its got to be something else.

Yes it was. Of course the first thing I did was factory reset. To me it seems to be not just this single unit problem, I've checked another unit in another store, and it seamed to have the same problems.

You have to compare it with another display to see the difference, when viewed alone, 100% yellow might seem fine.
The photo I did isn't very accurate, the difference is actually not that much dramatic.

There is another photo, some other guy did with his 55w905a on the left http://fotkidepo.ru/?id=photo:904646 . It's not a clear representation of what i'm seeing, but at least close.

Here is what i'm trying to explain: http://www.fullhd.gr/images/stories/...inema2/cie.jpg . That's a gamut of 46w905a, it shows that if life color set on low, green is shifted towards blue and yellow is slightly undersaturated. In case of life color off ( http://www.fullhd.gr/images/stories/...inema1/cie.jpg ), green is just undersaturated and so is yellow.
But on 55w905a these problems are much more pronounced.
I'm trying to find a way for fix it somehow, it actually may be impossible to fix.
Maybe there exist some custom firmware for this tv or some kind of option in service menu for color adjust?

oxygen7, first if your using Live Color my suggestion is don't! Oh it may look pleasing to the eye but it over saturates colors and at times will undersaturate colors. Second I have compared my set to my older 46HX850 and my friends Samsung 8000 and in both cases the yellows on my W9 beat both of them as did the overall PQ and black levels. Its hard to say why your seeing what you are but if its a used set that may be the answer as used store sets are on almost 24/7. But honestly I don't know because this is the first time I have ever heard of someone having an issue with the yellow color of the W9, there may be others I don't know. But here's the thing if you aint satisfied with what your seeing then by all means return it, I would, unless you can live with it. With the W9 the positives of such a great tv far outweigh the negatives but its up to the individual person to make that call. For me its been the best HDTV I have ever owned and I have owned a few of them!

Are those results pre or post calibration. I'm almost thinking pre since two presets are compared.

This is actually one of the most accurate TVs for color out there right now after the white balance has been calibrated. For example, below is the post calibration results from a review on the internet. I can confirm that mine looks very similar after calibration.

If you can't get results like that after calibration, than the tv is likely faulty in some way. I would stay reset to defaults and either get a meter or have someone come do a pro calibration.

Using Live Colour on Low and dropping saturation by a few points (=45-49) gives punchy colours without being too oversaturated. I like that setting, it's worth a try.

In the first comparison (your own photo), it's the W905 that is showing yellow. The BenQ, on that photo, does not show yellow, but lime green.

this one seems like the W905 has much few light output than the other one. Did you go into system settings and have disabled the light sensor in the Eco menu? When compairing to other displays, it definetly should be off. If backlight is lower on one one panel compared to another (in this case due to Eco light sensor), the picture often is described as "dull", "lifeless", "has no punch", and whatnotelse, even if it's just reduced light output. - Just turn the light sensor off, and probably your yellow will be so punchy and saturated, yummy!

Another point is -- viewing angle, indeed. The characteristic of the W905 panel is that of the RGB matrix, the green channel is losing contrast a bit quicker than the R and B channels when viewed from an angle. This is the reason for the "pink tinge" that is often talked about, and it will also affect colors like full-green (becoming more yellow) and yellow shifting a bittowards orange and become darker. Problem is, when you have two sets side-by-side, than you always deal with some kind of off-angle viewing.

On the positive side, it seems your W905 has pretty good screen uniformity. Compared to other W905' panels, there seems only very minor signs of "fingers" ate the left/right edges, or DSE/banding over the screen area. Seems like a lucky hit!

Thank you for your answers.

My 55w905a has approx. 1600 hours of operating time. It was the last one from store shelf when I took it. It is an equivalent of 5-6 moths on normal use and I don’t think it’s enough for TV to degrade in some way. Led’s don’t degrade that fast.
I know some tricks and definetly turned eco setting off, also tried setting hdmi full\limited range. color x.v.\normal. Also tried outputting 10bit x.v. color from my ps3.

Where could I download another firmware to this tv? I don't want to put the latest version from Sony site, because it is impossilbe to downgrade if something goes wrong. Some guy wrote that motionflow impluse mode became worse with the latest firmware.
So I would like to find some previous versions. Maybe someone still has it?

Previous Firmware's are hard to find for the W9. In days past you could down load previous firmware updates but with newer models that aint the case anymore so good luck trying to find one. That being said 1600 hour's is a lot of hours on a tv but not surprising for an open box tv being that they are on all the time. Could that be the reason for what your seeing? Could very well be but not sure. I really don't know what to tell you except maybe if your not happy then maybe get your money back and buy a different set. Would I? Yes. I stay far away from open box and refurbished TV's because I simply don't trust them because god only knows what they been through with previous owners/stores

My AVR won't give me the option to Auto Lip sync with this tv, it's a Yamaha, I've read that auto lip sync is supposed to be a HDMI 1.3 feature, the AVR is newer and of course this TV is new enough, maybe this is an AVR issue? Could it be my hdmi cable?? I'm a bit lost, but when I go into Lip sync on the AVR it won't let me do AUTO.


EDIT: According to the AVR manual
"Adjusts the delay between video and audio output automatically whena TV that supports an automatic lipsync function is connected to theAuto (default)unit via HDMI"

But I can't select AUTO on the AVR, any ideas??

ph00p, that's definatley and AVR issue! It should let you select AUTO. Try a different HDMI cord and if that don't work? See if you can give Yamaha customer support a call to see if they can help. But that is a head scratcher for sure.

Hiya Oxygen,

When I bought my W905A I was also not so satisfied with how the colors were represented. I used and tried many settings published online and also here. Then I went on a trial for my own settings using different technics to achieve as natural as possible for my ambient and usage.

I also had problem with yellow if I used Cinema 2 and Warm. Green was never green but was more or less all the time moving towards yellow. Here are my settings and now I'm very satisfied with all the colors. For calibration I used Nokia monitor test and Lagom LCD test (online tool).

best, d.
