Purchased Z ultra today.
The blacks are displayed as dark greys. Not deep enough. Is it my handset only which could be a defective panel? Though took a 5 min demo on a demo handset, as far as i remember blacks were deep enough. Right now, the blacks are worst than my galaxy note and even my HP probook and panasonic plasma tv! This is driving me nuts, how shall I approach the issue. I can't live with blacks which are greys and looked washed out on this flagship handset.
Am based in Gurgaon, India. Bravia Engine 2 is on. Firmware is - 14.1.b.0.461
Can you take a picture of the screen with a black background?

Now that is interesting. I am sorry to hear.
My Z Ultra has black levels the closest i have seen any LCD or TFT panel approach AMOLED. They are very deep and inky on mine,
One is with screen off, (second one) other two are with screen on. Picture displayed is a black reference level image. On my galaxy note, it is deep black and inky. On Xperia Z ultra, it is grey and washed out.

I've written a mail to sony, will be going to the store tomorrow, first thing in the morning to get it replaced. I hope this is not the true display I bought this phone for.

You can't compare amoled blacks with LCDs.

Ouch, that is not correct.
Here is an image of my Z Ultra i just took. Full Brightness. Blacks are very black to me.
Ill try to get a better photo tomorrow.
Yeah, on mine the blacks are nearly AMOLED level too. You probably have a defective one.

No offense but you have no idea what you are talking about. The Z Ultra does have fantastic black levels and they are the closest i have seen any screen come to AMOLED black levels.
Other reviews have also said the same.

It is officially release Aug 20 here but there are many imported units available ^.^

One way to avoid disappointment is not to make high expectation. If its good then happy, if its not then so so.

It's the first firmware version, so it's pretty normal to experience some bugs. I don't even think this is the final version, but a beta build that Sony rushed out the door for its Asia release. I'm guessing the firmware update that we (you) are getting in september is the "final" version. I would say that around 98% of the **** people here are experiencing with their ZU's on the current firmware are pure software bugs, and not hardware faults. THIS problem though (light bleeding) is 100% hardware fail.
TL;DR: This is not its final form.

which is smart for sony in consideration how long they USED to take to launch their smartphones to market before. Z for example was almost too late to market right when htc one and s4 became available. I say when Sony announces a new phone at an event, PLEASE start launch within 30days. it will garner even more sales. I have patience to wait for final 'software' :good: Apple is the smartest in this sense.

I only have screen bleeding issue when screen isn't on full brightness. Doesn't really bother me.
I posted this in another thread, but I took some pictures of the "screen bleed" (light from the buttons bleeding over into the screen) on my Amaze 4G. I also put up some pictures of my Nexus S, which has the same button configuration, but zero screen bleed:

Hokay, I added more pics to my album. Sorry about the terrible shakycam, I don't have a tripod or anything, and flash screws everything up.
Here's the two side-by-side. One thing I noticed: the Nexus is absolutely fantastic at preserving the blacks. I'm sure this is due to a difference in backlight/screen tech, but it's really impressive - black is just black on the Nexus. The Amaze is much lighter grey when it's supposed to be "black". Here's the two side-by-side with the backlights at their lowest and highest settings:
But even without any backlight or bottom lights, the Nexus' screen is still noticeably blacker than the Amaze. I also added another picture I found elsewhere on the web with two versions of the Nexus S - it is just a difference in the screen tech (SuperLCD vs AMOLED). That may be a factor here as well.
I'm not trying to discredit the Amaze at all - I own it, I love it, and I plan on keeping it. The screen bleed is probably made worse/more noticeable by the screen tech choice, which isn't as good at reproducing blacks. This isn't a huge issue for me, but I just wanted to document the differences here. I'm just taking the best pictures I can to represent it - it really is noticeable in person too, if you care about such things.
Can you take pictures in normal daylight on it's auto light settings to show how it looks in real life..

Wow, indeed. I didn't think the blacks would be so different on the two phones (which is why I thought it came from your pictures - evidently I was wrong).
Those pictures are awesome and clearly show how the bottom lights affect the screen, thanks!
Not enough to make me reconsider (though maybe I'll change my mind when I finally have it in hands).
My friend had a very similar light bleeding in his EVO...one day he broke the screen and when replaced with a new one, the problem was gone. so it was a manufacturing issue on the first screen.

Hokay. I've added some outdoor pictures, and a set of indoor pictures in my dark apartment now that it's day. Updated link. It definitely is much less noticeable outside (although I spend a considerable amount of time inside that I count as "real life" as well ), and the Nexus screen is still blacker, although not as much.

Yeah, the side-by-side Nexus pic I found really demonstrates that. It's not nearly as disparate outdoors, but indoors it's pretty noticeable. And it is just the screen tech - screen techs have their pros and cons, black reproduction is only one aspect of screen quality.

Not a performance issue but could be an easy software fix just have the keys dim with the screen. Sent htc an email so other versions might be better.. but I'm sure once we get root there might be a fix for it

All the LEDs are capable of being dimmed, you just have to give them less power.

Not terribly on-topic, but LEDs are generally actually dimmed via pulse-width modulation - basically, if you want 50% brightness, you turn them on for 50% of the time, off 50% of the time, at >60Hz. Among other things, LED color depends on current - so supplying less current would not only make them dimmer, but change the color.
What does screen bleed look like? I got my new C3 serial model and I see white coming out on the sides when the screens all black? Please don't tell me that's it on my 2nd friggin prime!!!
Yup, thats bleed.
Since you have a C3, have you tested your Wifi/BT speeds at the same time? Just curious how yours is performing.
I haven't tested **** yet because I finally got it updated to 21. I'm so pissed. I can't believe I have to send yet another prime back. Are u ****ing kidding me
Is it really bad? Possible to take a pic for us?
Mine has some along the right side but since everything else works on mine cept GPS I live with it.. C3's are supposed to be good batch but looks like they're like the others as well..
Mostly on the right side.

Once you posted these pics, I had a look at mine too. I too have a screen bleed ( I think two of them) on the right end of the screen. Now I can nitpick, rant and rave and all as much as I want, saying that I payed $500 of my hard earned cash that it better work 100% well. But guess what, its been a month since I got my device and so far I have never, ever noticed this. I watched a couple of movies too, but never noticed it. So, though technically there may be some flaws in my device, for all practical purposes it is unnoticeable and okay. I believe screen bleed is due to the screen being screwed a bit too tightly, so it is technically not a hardware issue, it is just a slight fitting issue which can be fixed if you open your device and tinker.
Similarly, my prime has 2 bright pixels (dead pixels that is). Still, I have never been bothered by it. Now, I may obsess about the screen bleed for a few days (because I just discovered a new "defect" in my prime thanks to you! nah, I'm joking, it's cool! ) but still I'm not gonna notice it.
Now your screen bleed seems benign too! If you notice it often, return it else keep it! As simple as that, bro!
\m/ Btw, my prime is a C1... Peace!
Sorry to see that man, that definitely looks worse than mine..and with a C3 you def got a right to be upset
You know, I lurk on ipad forums a lot. There's no question that almost all if not all ipads out there have back light bleed to some degree. And yet, ipad users don't really care about it since most people don't notice it until someone else points it out to them.
And yet on this side of the fence android users would cry bloody murder and make it out like it's the end of the world just because in a completely dark room with a device that is showing a completely black picture you can see some light coming from the corners.
For those who think backlight bleed is the end of the world, please do us all a favor and get a normal lcd display tablet. Or go get the ipad.

90% of all LCDs have some form of screen bleed. TVs, Laptops, LCD monitors, iPads, etc. The reality is that it is just a consequence of the technology.
Unless you have incredibly prominent screen bleed that is distracting when the screen is not all black, or distracting enough to notice while watching dark movies, I wouldn't worry about it much.
From the photos you posted I don't think you have much to complain about.

I have an ipad2 and the new ipad with no lightbleeds. But the early primes I bought 3 of the 5 primes had definite light bleeds on more that 1 area and 1 had dead pixels. This is from my experience. Maybe I just have the worst luck with the prime like a few of the members here.

I have a tf101 32gig model and just bought a prime. It's got absolutely no light bleed whatsoever. It locks onto the gps in about 30 seconds and always sees at least 8 sats, sometimes 10-12, at any given time. Neither my transformers have any light bleed at all. My 16gig model did have some light bleed, though. Last year, I bought an ipad and ipad 2 and they both got light bleeds.
There have been plenty of articles regarding light bleeds on the ipads and that chances are if you got light bleed and want to exchange for another you will get another with light bleed.
All ips display devices are prone to backlight bleeds. Most people don't care about it because it's hardly noticable. Only a few people like yourself think it's the end of the world.

You got me LOL.
I am now officially a proud owner of a prime with a fully working gps, strong as hell wifi signal, and no back light bleed whatsoever. Can't wait for the dock to arrive.
yeah my wifi works too and my gps is fine for the most part, was on my first unit too - this unit has a tiny bleed but it's barely worth mentioning compared to the amount of bleeds the tf101 had. Alot of people around here really can't appreciate how much better this tablet is over the original transformer.
Do you really notice that bleeding with normal use? Mine had this:
Which really has those bright spots, but this seems pretty gentle, however it shouldn't be there..
That screen bleed from the op doesnt look bad at all...
Room looks pitch black, and thats all you see. I can guarantee you can't see that during normal operation.
Op: your screen bleed actually is not that bad. I would not take another chance sending it back because you might get worse.
It took me 3 times before I got one that was tolerable. But then I opened my prime and fixed it by loosening some screws.

Calm down slick. Even two devices doesn't mean that every product off the line will have it. Unless they had checked 20 devices and every one had the same problem, I'm not writing of the device. There are defects. Some people have Nexus 7's with no light bleed, others have it with some light bleed.

Of the 5 reviews so far only Engadget mentioned leakage, everyone else is highly satisfied with the screen. Cnet mentioned these are presale models being tested, so let's just wait for the final version.
With the new Nexus 10 coming out, I strongly believe Apple is going downhill. I do not want to be cynical but had Steve been still alive, this would have never happened. When I saw the Ipad Mini, I thought "This is going to be my first Apple product, though expensive". Then Google announced Nexus 10. Everything changed dramatically. I want Google, and nothing but the Google, so help me God(if any)!!!
Light bleed is kind of a big deal to me too. I don't care about anything being really much over 1920x1080 (although it has to be at least 300PPI for me with Pentile displays, I can still see it), but light bleed might be the deal breaker here when I see this thing. It is not like I absolutely need a tablet with a good desktop, laptop, and phone. I'd be getting it for media and browsing around the house and workplace where screen quality will be the #1 focus.

+1 Can't stand light bleed.
It seems that the contrast is nothing special either, but that's because it's not as bright as other tablets. The black level looks decent according to the tests.
D: ohh lol i hate light bleeds
Does warranty cover light bleeding?
Any LCD with a backlight will suffer from light bleed to some extent even the iPad3 retina (just Google for the pictures). Obviously, something to check for and exchange if it's significant. The pictures on The Verge don't show any signs of it and the pixel level comparison shows the Nexus 10 display to be superior in black level, colors and sharpness against retina.
What is the brightness of the screen, anyway?
There is a firestorm going on over at Engadget over this review. The same reviewer wrote the iPad mini review and fawned over it but nitpicks the Nexus 10. Engadget has been deleting posts that point out the flaws in the review (and back it up with evidence).
I wouldn't put too much stock in this review, but it's always a good idea to be skeptical.

When the spread of the backlight is uneven, so parts of the screen are brighter than others.
I always thought light bleed was the presence of light when there shouldn't be any. Like when you're watching a movie in portrait view, and the black bars on top and bottom show light. That's why I haven't wasted much time with IPS in the last couple years ever since discovering Samsung's AMOLEDs. Uneven backlighting is a different and even worse artifact, and again it only affects non-AMOLED screens.

I always thought light bleed was the presence of light when there shouldn't be any. Like when you're watching a movie in portrait view, and the black bars on top and bottom show light. That's why I haven't wasted much time with IPS in the last couple years ever since discovering Samsung's AMOLEDs. Uneven backlighting is a different and even worse artifact, and again it only affects non-AMOLED screens.

Seems like they both have pros and cons. Amoled displays have high risk of tint, I experienced this in my s2 for about a year until I finally got a replacement. This one portrays whites much better, or at least now it does. Aside from that you have all benefits, thin capacitive touch layer, vibrant colors (I don't give a **** if they're over saturated, they look great and that's what matters), no risk of light bleed, and huge potential battery savings. In my personal opinion I would take an amoled panel any day. I mean, displays like the super lcd2 in the one x are brilliant, but come on,, have you seen the note 2 on dynamic settings ?

Wished Samsung had gone with SAMOLED. Without a backlight there's no backlight bleed, ghosting, uniformity, etc. issues.

The technology is not there yet, nor is the economy. They simply can't produce a 2560x1680 OLED panel, 10" or otherwise, at a price anyone would be willing to pay.
Look at the PenTile "tricks" they have to pull on Galaxy phones as an indicator of how they're struggling with the tech, look at the very high cost of the Tab 7.7 to see how expensive it gets when you increase size, and to further reinforce that look at the ludicrous price of their big screen SAMOLED televisions compared to LCD and plasma.
Give it a few more years, it'll be feasible, and Samsung is surely working very hard on the problem, since they have a lot invested in pretty much owning the OLED market.
You're right. This is going to be the best 10" screen for the next 6-12 months. Yes it won't look as good as the screen on my S3 but I will be more than happy with it.
8 days and counting!
Hopefully a PCWorld/Currys near me will have it ready to take away!

I am very close on pulling the trigger on a ZU, coming from a Note II. However, I am quite reluctant to take the plunge because there several serious issues plaguing the ZU, so it seems.
First off, I have heard many nightmare stories about spontaneous cracks that happen for no particular (self inflicted) reason and that it takes weeks to months after to get the phone back and sometimes needing to pay for it. This of course is atrocious service by Sony. I have read a statement from Sony, saying they repair single cracked displays. Anybody experience with this issue and is the ZU really that fragile? It's a big phone and needs to survive in a jeans pocket, logically.
Secondly how bad/ good are the black values in the dark on the ZU? In daylight they seem fine, but in the dark, in bed, watching a movie... Not sure.
Thanks guys.
While I mostly watch comedies or TV shows on my phone and leave more serious watching for my ht room, I never felt bad about the black levels although it's not on par with my previous note phones. My gf is getting note 2 tomorrow so I can take some pics side by side showing the same dark movie scenes.

Thanks for that, I appreciate it. It would probably be best to take them in a pitch black room, as it would be more accurate. No experience with sudden cracks, eh?

I have only read about two or three guys around here that have cracked their screens, so it doesn't look like it's a widespread issue. It is a 6.4" sheet of thin glass though, so you should be careful with it no matter what. The screen is an LCD, so you won't get deep blacks in the dark, since LCDs have a backlight (LED). AMOLEDs don't have that, so that's why you get those deep blacks. Even my old Galaxy Note had a grey-ish black when i used it in the dark, since light from the neighbouring pixels would illuminate the area around.
The blacks looks good in normal light, but it won't look that black in a dark room. That's just how the technology works.

Thanks for your thorough reply :good: Regarding the sudden cracks, people blame the design for it, that the power button placement is the culprit. I.e. the enclosure not being strong enough and it's a design fault. Where I'm from, Holland, there was a tv show that shined a light on the many Xperia screens that cracked, particularly the Z. Hundreds of people had this issue and basically Sony left them out in the cold for weeks to months, saying there wasn't such a problem. We all know they released a statement where they state otherwise and single cracks will (no impact) be repaired under warranty. I am not eager to grab the ZU from my pocket one day and welcomed by a 'sudden crack'. This of course is a risk and a risk any adopter takes.
Regarding the black values, how is the quality of HD content in the dark, I mean are the blacks 'good enough'?

You'll just have to take the chance at this point, but it shouldn't be an issue at all. If it was, you'd be seeing a lot more people complaining around here. Regarding the HD quality in the dark, i don't think you'll have any complaints. The colors and the screen is overall fantastic, but it may take a few watches to get used to the more natural colors if you're used to AMOLED, which in most cases makes everything look fake.

You're absolutely correct on both counts. I need to take the plunge. Yesterday at Mediamarkt the ZU had a dead battery so that didn't help me taking a look at the screen. I will be doing that today at some other stores.
You're absolutely right regarding the samoled screens, they made my eyes adapt to very cartooney color reproduction. Sure it can make everything pop and the blacks are overall (not always) great, but realistic...no. I'm hoping the ZU is the middle road between the sammy's samoled and the somewhat boring IPS displays we see in LG or HTC.
Follow up: So I went on my bike to the city in the worst storm, with rain, hail and thunder, but I conquered the elements, only to be greeted in the end by the marvelous ZU. I saw it yesterday in white and today in black and damn it looks so damn classy in black. A phablet from the future. The screen is pretty much insane, a middle road as I expected, between samoled and LCD IPS. I watched some movie trailer and everything seemed insanely sharp and crisp, with natural realistic color tones.

I'm pretty sure you'll only get one opinion out of us here. Which is take the plunge!
I took the plunge so far I've even got two of the bloody ultras!
It's a long story.
I've come from a Galaxy Note, Galaxy Note II, and Galaxy S4.
I'm far happier with my Ultra. You will be too!
Alright so a final question regarding contrast, black levels that is, how is it for you guys? Especially in pitch black (at night, while watching videos)? Erica Griffin, who is also a XDA member, posted her review on the ZU on Youtube and mentioned her pretty bad contrast level of 680:1, whereas others have a ratio of 1000:1 and above. What are your findings? The Youtube time link can be found here:

I can't meassure my screen since i have idea how to do it, but remember that it's an LCD, so black won't be black in a dark room. It'll be gray. My friends brand new Samsung Galaxy TabPro has an LCD, and it's the same story there. Even AMOLEDs won't be pitch black in dark places. It'll be darker, but not completely black.
I don't know what else to tell you. You'll have to just check it out yourself and see if it's something you can live with or not. I watch tv shows on my Ultra every night in bed, and i'm not complaining.

Yeah the tech between amoled and lcd is vastly different, which results in various color/brightness traits. It seems there were two different panels used for the ZU, namely the AUO and Sharp, as seen on this image. Perhaps this is why there is a different contrast ratio across the board.

That would be impossible since there is still a small current flowing through the pixels, so they are never really off. But yes, closest to black as possible.

That would cause smearing, sadly, as seen with the Note 3. They fixed that later, not completely turned off.

About the cracked screen, please be careful. I thought that it could never happen to me (I use all my phones with a lote of care, as they are expensive and difficult to repair on warranty in my country). I took it out of my pants, as hundreds of times before, and a cracked screen greeted me. I've been without my SXZU for one month now, and no easy fix awaits. No warranty from Sony (I showed them those web pages where Sony acknowleges the problem), so I have to pay $600 USD to repair it.
I checked other web sites to buy the part (between $150 to $210), but I'm wary about two themes: 1. The quality of the spare part. And 2. I've been looking for instructions on how to repair it myself and let me tell you, it's not easy at all. You have to take the phone apart to get to the display. So I have to look for an expert. An experts are not cheap.
So, it is easy to break and difficult to repair. But you are living in a country that is known to repair on warranty those screen damages, as long as there is just one crack.

Not sure if the ZU is really easy to break. I asked some reps at the shop about it and they told me the problem was really widespread with the Xperia Z, not the ZU. Some people cracked the ZU, sure, but many have not. Not sure what could have caused yours. Hope it works out for you and next time you should probably get a cheap phone insurance which covers these things.

Agreed...
And if possible, a good case/bumper for it too...
I must say, I've never seen a screen worse calibrated than the one in the Xperia Z Ultra I've bought today.
yellow tint (fixable in latest firmware, but then dark tones get messed up and pushed into blue tint...)
heavily compressed bright tones (ugly faces, dull colors)
heavily compressed dark tones (shadows completely crushed)
low gamma
heavy banding (produced by the crazy stretching of midtones)
Is there any way to fix it? (maybe a gamma calibration control through a custom kernel, really saved my Nexus 4 before, which was bad, too)
See my other reply in the Pimped Kernel thread
Hmm, well that ain't normal. As you can see, there aren't any "display issues" thread in this subforum, and everyone around here are happy with their screens (no complaining until now at least), and all reviews of the device shows that the panel is very good with very accurate colors (which Erica Griffin also concluded with).
I believe you've got a defective panel. The screen should look very good with accurate colors, and acceptable black levels (in the dark. They are good in daylight).
Keep in mind that Sony uses two panels. Sharp and AUO. The Sharp is the best one, but the AUO isn't bad. I've had them both.
"All things considered, the Sony Xperia Z Ultra certainly has the best screen on a phablet at this point. The sheer size and the resolution advantage, combined with the decent to great performance in all other important aspects, see the Z Ultra inch ahead of the LG Optimus G Pro."

I'm the opposite. I've had both, and the first thing I reacted to when i got the Sharp panel was how good the contrast was compared to the AUO, so i'll have to disagree!

I'm guessing no matter what panel you get, every ultra will be different.
On that note, here is a side comparison between the two just for the hell of it. Sharp on the left and AUO on the right. Sharp has just the bare screen. No anti-shatter proof film. The AUO has the anti-shatter proof film and the Mocolo Premium Tempered Glass Screen Protector.
EDIT: Comparison pics were flawed.

Can't tell a difference. However your middle pic shows a differences because of the lighting in the room. Notice the one on the left has light from the doorway maybe? hitting it but the one on the right doesn't.
Either way, I believe this phone has the best screen besides the LG G Pro(I haven't any other phone to compare it to). Whenever I help my coworker with something on his G Pro, I start missing that screen when I had that phone.

Good eye!, though now that I look at it more. I think I might have had a defective screen on the sharp panel.
