No offense, but I'm not sure I buy angelofmusic's claims. Contrast ratio and black levels are not something obscure that you have to measure to get a feel for; if they're lacking, it's obvious. Now the Z Ultra may not have the highest contrast ratio ever, obviously you'd need measurement to quantify it, but EVERY picture/video I've seen so far has it looking good. Every shot of the device next to something else, even the HTC One that angelofmusic praises, has it on par with the other device. Every hands-on/review I've seen compliments the screen, and many rave about it.

All this is to say that, if the display were lacking in some area (and especially if it were lacking in multiple areas like angelofmusic alleges), you'd think that SOMEBODY would at least mention it in passing, especially considering all the irrational hatred that swirls around this phone from certain people, who are actively looking for something to complain about. But they don't. Everyone compliments the display, some say it's the best mobile display they've ever seen, and when words like "contrast" or "black levels" come up at all, they are invariably praised.

And then out of nowhere, angelofmusic comes in and tells us we're all wrong, that the display sucks. I'm sorry, and again no offense is intended, but we would not be doing our duty as rational humans if we believed this guy. It's everybody who has used this device and every picture of it I've ever seen against him. I think he has a defective unit, or perhaps made a mistake in the measurements. It just doesn't add up.

Thanks :) Keep up the great work. I always find it interesting how in depth you go.

Have a great day :)

I have to say, the display on my personal Z Ultra is beautiful. When I view my photos etc on the device, I'm seeing colours in them that I never seen before on other mobile devices. I am very very pleased with it :)

Still as usual, Sony use 2 type of display. I am pretty sure on this as I had compare with my friend unit before, his one is more cool temperature than mine.

One is warmer, another is blueish. Mine is more on warmer temperature where my friend one is more white but more to blueish.

I never measure it but mine look as good as it suppose, it even make the HTC One look blueish when compare with it. Remember they is 2 type panel in market, one is warmer temperature where another is cooler temperature.

Sample shoot comparing mine (black color) v/s my friend one (white color).

Also here comparing my unit v/s HTC One. (Bravia Engine 2 is off in Xperia Z Ultra)

Here another user comparison of Xperia Z Ultra v/s HTC One - http://www.xperiablog.net/2013/08/09/xperia-z-ultras-display-goes-against-the-htc-one/ Obvious his panel same as mine more warmer.
[Sony Xperia Z Ultra] angelofmusic:
Dude, educate yourself. Go pick up a device and play with it in the conditions I'm talking about. You have no experience with this device. Seriously be quiet!

Measurements don't lie! Colors are nice! Blacks are bad. There is no argument.

---------- Post added at 06:47 PM ---------- Previous post was at 06:43 PM ----------

Now this I would like to see. How are your blacks? And if you turn your device when you see a black image do you see how the image turns grey or almost white?
[Sony Xperia Z Ultra] Andrewtst:
See my above post, it is obvious 2 type of panel is use by Sony in Xperia Z Ultra. This is happening at Xperia Z as well.

Obvious your unit is more on cool temperature base on your written judgement.

If you look careful on my snap of 2 different type panel, then you will notice the warmer temperature unit had better black level than the cooler temperature one.

Also I had compare my warmer unit with HTC One and it clearly show Xperia Z Ultra (with warmer temperature panel) is better output than HTC One.
[Sony Xperia Z Ultra] Andrewtst:
Mine is pure black, I had test it before with 100% full brightness. I notice my friend one (which more on cool temperature) actually not as black as mine when put in 100% full brightness, also when both unit put at far distance, my friend one having a bit grayish but mine still show in pure black.
[Sony Xperia Z Ultra] angelofmusic:
You can tell diddly squat with the pictures you show. You have to show them without ambient lighting on a black image to be able to tell and be relevant.

But yes, I believe you, though this doesn't make my argument any less relevant if half are this way.
[Sony Xperia Z Ultra] Andrewtst:
It is hard to snap without ambient lighting as I just use another phone camera to snap it.

Agree where you doesn't make argument any less relevant but due to

Sony keep using different manufacture for screen panel

and thus always given different quality output and my small review / others user comment relevant as well due to them is getting a warmer temperature panel which is great and in my opinion better than HTC One.

After compare my friend one and also few times compare with sample unit at shop where some show cool temperature, some is warm temperature, I can only said they is some great panel in market and some good panel in market. The cool temperature one still is a good panel to me but if compare both, then I will given the warmer temperature one great, I only compare mine one with HTC One that time, that why in my review I give Z Ultra panel is better than HTC One.
[Sony Xperia Z Ultra] angelofmusic:
Was this done in the dark or not?

If not in the dark, it doesn't matter. Also you should measure this display. Can't make a full argument without those.
[Sony Xperia Z Ultra] Andrewtst:
For me it is pointless to make measurement, normal consumer will look straight on it and see the result, measurement is too technical and not for normal consumer and frankly speaking useless during daily use.

When in the dark, my panel is still black but not as black as AMOLED, this is impossible as for the moment, no way LCD can have same black level as AMOLED.
[Sony Xperia Z Ultra] angelofmusic:
And where are you located? Where are these devices originating from?
[Sony Xperia Z Ultra] Andrewtst:
I from Malaysia and I get it from local Sony Centre shop.
[Sony Xperia Z Ultra] angelofmusic:
You are missing the point. We can't say much about true differences unless you have measurements to prove it. We also need to see different manufacture proof and origin proof to say where what Is coming from.
[Sony Xperia Z Ultra] Andrewtst:
I only review it base on 1st hand, and see thru eye, I believe a lot user here also judge base on own eye.

Not much will actually spend time measure it because it really is over technical, also some user prefer warmer, some prefer cooler, 100% accurate does not means it is perfect as different human different preferable.
[Sony Xperia Z Ultra] angelofmusic:
Again you miss the point of what I am trying to accomplish. Really not helpful here. Do you know where yours was manufactured? Your information could be helpful.
[Sony Xperia Z Ultra] Andrewtst:
I had no idea and not sure how to check on it. Xperia Z panel checking tool is not workable here.

But your insist said Z Ultra is not better than HTC One is understandable as I am insist said Z Ultra is better than HTC One due to we are getting different panel.
[Sony Xperia Z Ultra] AntiLazarus:
Yeah see, I'm even less inclined to believe you now that you're being petulant. No one in my area has the device, so I can't try it out at this point, or else I would.

And measurements may not lie, but your eyes ARE a type of measurement. The contrast can NOT POSSIBLY be as bad as you say it is with the black levels this thing displays. Black levels are clearly on par with the HTC One (they may not be as good, but they are obviously in the ballpark, your eyes do not lie that much). In order for the contrast to be as bad as you say it is with the black levels it is, it would have to be an extremely dark screen, which it is obviously not. It is not possible for the screen to be as off as you say it is without anyone being able to detect it.

Measurements may not lie, but people sometimes do. Even if you're telling the truth, we don't have any way of knowing whether you are competent to make the measurements, or if you have the proper equipment.
[Sony Xperia Z Ultra] angelofmusic:
You are seriously not worth my time. NEXT. If you knew what I do you would not question me, and many people on here do know me.

---------- Post added at 08:05 PM ---------- Previous post was at 08:03 PM ----------

HAHAHAHA that is great. Just sitting back to watch the insanity unfold. Yeah whatever, people can question me. It seems there are two different panel manufacturers or panel revisions. One has issues with contrast ratio and seems to be of a blue color temperature (not so nice). And the other seems to be of better contrast and also warmer. I reached out to the press channels to get an answer. Reaching out to a more serious channel who is interested in R&D I should have known better.

Xperia Z Ultra’s Triluminos Display compared against Xperia Z Display. ( Brightness / Viewing Angles )

I'm "not worth your time?" Bub, no one's paying you to be here. Your time is just as useless as mine is on this forum.

At any rate, I'm not trying to harass you, I'm just simply asking you to explain exactly how it is that everyone who sees this panel EXCEPT YOU is bowled over by its quality? If you're going to raise these allegations against the panel's quality and against the unanimous consensus (again, except for you) of owners so far, then you're kind of obligated to provide some type of explanation for the discrepancy. Because right now there is a BIG discrepancy between your claims and people's experiences. One that science does not support. I am asking you to rectify the situation. Explain why it is everyone else seems to be hypnotized into believing this is a good panel, when it is really not?
[Sony Xperia Z Ultra] angelofmusic:
This does not show contrast ratio but is nice to see =) Viewing angles are better no doubt. Plus Triluminos Quatum Dot film helps with saturation. But how does it fare with blacks? And do you see it leaking light at an angle and turning grey. Some panels are doing this.

---------- Post added at 08:16 PM ---------- Previous post was at 08:14 PM ----------

Pay attention. It looks like there are two different displays, which is typical of Sony. Think critically here. Don't attack those who bring you valuable information! Question Sony, which is exactly what I am doing now through media channels. If you want to sit here and argue go ahead, while I be productive and get an answer. I won't answer to you again.
[Sony Xperia Z Ultra] ImAnurag:
No i didn't see or noticed anything like that :rolleyes:
[Sony Xperia Z Ultra] AntiLazarus:
I AM thinking critically. Which is why I asked you explain the Grand Canyon-sized chasm between your measurements and people's experiences. Because clearly there is one, and it needs to be explained. Simply replying (in effect) "No one knows what they're talking about except me" does not help us resolve the situation. On account of your refusal to reconcile the conflicting reports, I came up with some hypotheses of my own, one of which was that you had a defective unit. Now, as another poster pointed out, it appears there are two different displays being used. That is not the same thing as you having a "defective" unit, but it is close enough for me to feel somewhat vindicated in my suspicions. However, you initially regarded it as absurd, and insisted that "all of the units will have this problem," which now appears clearly incorrect.

I look forward to any new information you can provide and thank you for it, but I hope in the future you will learn to present yourself in a manner more befitting an adult.
[Sony Xperia Z Ultra] angelofmusic:
I already have all the credentials and many know this. I am looking for serious answers without coming to an argument. I have measurements, its a part of what I do. I am the only one who has done measurements so far. I expected others to chime in with measurements too or something to contribute, not waste time by asking how I know all of this. I explained who I am and what I do. What I said is that all panels have this compression processing in shadows and too low gamma for highlights and midtones. This is just what Sony is doing to make the display pop. However, my reason for being here is to gain insight to see if all of the displays have a contrast issue.
[Sony Xperia Z Ultra] Andrewtst:
I agree you on this, it seems the unit he get is defective as I seen some one post before.

Even thought mine and my friend one seems different panel as different color temperature, but does not means my friend panel that bad as he describe.

My friend one also don't have grayish issue when in 100% brightness. His one only show slightly gray out when put phone in really narrow far distance.

Highly suspect his unit is defective.

I had seen a lot Xperia Z Ultra and can 100% confirm no black issue and never worst than HTC One.
[Sony Xperia Z Ultra] ScottishSwan:
I second that. Black levels on my handset are also fantastic and very inky.

Just asking. Do you go round Smasung forums and nag without giving up that AMOLED has an irritating blue tint or over saturated? I mean you seemd extremely insecure that we think Xperia Z Ultra's display looks great.

Why is everyone bashing her findings?

She has come here with her findings and just because it does not match up with what people "see" on video's and in real life does not make her findings any less relevant.

Professional calibrators (who would use the exact same equipment as angelofmusic) as an example know a bad screen when they see one as their eyes are trained to spot the differences us normal folk just would not see so a perfectly good panel for old joe would be frankly a piece of garbage to a professional calibrator. (look on hdtvtest, avforums etc for a very detailed explaination of contrast ratio, dynamic contrast, black levels, viewing angels etc)

The biggest thing to remember here is if YOU are happy with what YOU see then that is great and enjoy your phone and move on.

P.S I am in the camp of that screen looks great but with holding my judgement until I see one for real.
[Sony Xperia Z Ultra] Andrewtst:
Because she too insisted and judge seems Z Ultra screen is that bad but in actual it isn't. I even show her they is different type of panel but she still unstoppable asking about grayish black issue. The real is they is no black display issue. A lot user also report no such issue, means her unit is defective or she just a kind that love to bashing certain brand that not her favor. I believe she is not the second type and high possible the unit she received is defective.

I just check her YouTube and didn't find any video about Z Ultra also.
[Sony Xperia Z Ultra] xman_here:
Capable of 4K video. SONY HONAMI has leaked with some crazy specs. Might be a real winner when it launches. I'm excited.

It's here. I haven't watched it yet since i have to make some popcorn first, but I'm excited and i can't wait for the display verdict. Cities will burn, and people will get killed, so be safe out there, people.

Update: OK, i've watched it now, and i now understand what she was trying to tell us.

[YOUTUBE]9P98sliPh3k[/YOUTUBE]
[Sony Xperia Z Ultra] AntiLazarus:
I watched the video, and I can definitely see what she means with the black background, but I strongly suspect it is some software problem. It looks to me like a pure black image is much brighter than incidental blacks in a picture. If they were really that bad all the time, wouldn't you be able to tell? The contrast wasn't really up to snuff on the original Z, but you could tell without looking at a black image in the dark.

At any rate, people may have already seen this video, but the blacks in the Z Ultra here look much better to me than they do in her video:

http://youtu.be/osxZn4T1j0U

I mean, how could you even sell somebody an LCD panel in 2013 with a contrast ratio below 700? It looks to me like Sony would sue the manufacturer for breach of contract, because I can't imagine them actually agreeing to buy panels with such a low rating.
[Sony Xperia Z Ultra] LordManhattan:
1. She said that the blacks are grey-ish if you:

a) Turn the brightness to 100%

b) Go into a completely dark room

c) Rotate the device a few degrees

The blacks look very good in normal day light. I also checked out the video you posted, and it's the same there. I took some screenshots:

Looking directly at the screen:

Looking at it from a different angle:

Still, this won't change my mind. The screen

is

fantastic in "normal" scenarios, but it might be a problem if you are reading ebooks in the dark with a black background (like i do).
[Sony Xperia Z Ultra] AntiLazarus:
Right, but to be totally fair, I just checked (in the closet with the lights off) and my Nexus 4 shows very similar performance at similar angles. To be specific, the black levels show gradual shift when the display is rotated about either axis, but shifts fairly dramatically when rotated by even small amounts along BOTH axes. I think the Nexus 4 is generally regarded to have a pretty good panel, so personally I'm not that bothered by these black level shifts at such extreme angles. At least in the video I linked to, I would personally be happy with that level of performance, especially if the panel looks as good during actual use as it is reputed to.
[Sony Xperia Z Ultra] LordManhattan:
So you came out of the closet today? I kid, i kid :p

But yeah, i don't see this as a huge negative. If we want really deep blacks, then we'll have to get a device with AMOLED. LCD screens have back lights, so it's pretty obvious that the light will be visible in the dark. I love deep blacks, but i know what i'm getting into, and i accept the lack of true blackness.
[Sony Xperia Z Ultra] jewelkobayashi:
Yes, it was her findings. Need to respect her finding and opinion, like others opinions need to be shown respect, no matter how un-scientific it is. If she is going to take a scientific approach, then conduct tests in scientific manner. You do not need to be a scientist to realise that test result from ONE SAMPLE UNIT is not definitive enough.

If a scientists/ researchers cannot question the status quo objectively, think out of the box or suspect contaminated evidence due to arrogance , pride and/or defence of one's reputation, it is recipe for disaster.

It is my opinion that her arrogance and condescending attitude grated people the wrong way, even when no one was hostile to her findings in the first place. The only thing people did was 'question' and ask for explanation.
[Sony Xperia Z Ultra] Andrewtst:
Finish watching angelofmusic video review, Z Ultra is still using LCD, they is no way pure black like in AMOLED in complete dark area as they is backlight issue from LCD. Only AMOLED cannot have such issue.

Unless you want to hurt your eye, they is no point push 100% brightness, I never use though and I let it adapted to light situation and it work perfectly fine.

Her review a bit like purposely picky on the weaknesses of LCD, all LCD will behave like this, this is weaknesses of LCD.

AMOLED don't have but AMOLED wise will face crushing black level which destroy details in dark scenes area when viewing photo / video.

Both AMOLED or LCD having it own weaknesses.

As for pocket comfortable wise, her jeans is too tide and pocket too small, none of the device can fit nicely in her pocket. For normal traditional jeans, they is no issue fit in comfortable the device.

[Sony Xperia Z Ultra] LordManhattan:
You do know that LED and LCD is the same technology right?

The basic technology is the same in that both television types have two layers of polarized glass through which the liquid crystals both block and pass light. So really, LED TVs are a subset of LCD TVs.

LED, which stands for “light emitting diodes,” differs from general LCD TVs in that LCDs use fluorescent lights while LEDs use those light emitting diodes. Also, the placement of the lights on an LED TV can differ. The fluorescent lights in an LCD TV are always behind the screen. On an LED TV, the light emitting diodes can be placed either behind the screen or around its edges. The difference in lights and in lighting placement has generally meant that LED TVs can be thinner than LCDs, although this is starting to change. It has also meant that LED TVs run with greater energy efficiency and can provide a clearer, better picture than the general LCD TVs.

LED TVs provide a better picture for two basic reasons. First, LED TVs work with a color wheel or distinct RGB-colored lights (red, green, blue) to produce more realistic and sharper colors. Second, light emitting diodes can be dimmed. The dimming capability on the back lighting in an LED TV allows the picture to display with a truer black by darkening the lights and blocking more light from passing through the panel. This capability is not present on edge-lit LED TVs; however, edge-lit LED TVs can display a truer white than the fluorescent LED TVs.

Because all these LCD TVs are thin-screen, each has particular angle-viewing and anti-glare issues. The backlit TVs provide better, cleaner angle viewing than the edge-lit LED TV. However, the backlit LED TV will usually have better angle viewing than the standard LCD TV. Both LED and LCD TVs have good reputations for their playback and gaming quality.
[Sony Xperia Z Ultra] Andrewtst:
I change my statement to AMOLED already, I am pointing to AMOLED in my previous statement as Samsung is using AMOLED panel in it phone not the LED. I previously wrongly mention, I never mention clearly as I though everyone knowing my talking on LED is means AMOLED as they seems don't have any LED panel use in phone also.

AMOLED no need backlight. LED TV is different story, LED TV is same as LCD as you said, it still and use different kind of backlight. LED TV is not as pure as AMOLED technology where no backlight is required.
[Sony Xperia Z Ultra] LordManhattan:
Yeah, AMOLED is a different story. Both have their positive and negative sides though. LCD/LED have more accurate color reproduction and uses RGB matrix, but can't really produce the deep blacks, while AMOLED produces really deep blacks, but produces over saturated colors (slowly getting better at this though), and they use (for the most part) pentile matrix, which is no bueno.
[Sony Xperia Z Ultra] Andrewtst:
Ya, that the reason I not really like AMOLED, it just over saturate most the time with missing of one blue diot to extend it life span.
