[Xperia Z Q&A, Help & Troubleshooting] luke997:
Photography is my hobby so the more accurate colour reproduction - the better I like the screen.

And I like the screen a lot!

Had Galaxy S2 and even with the lowest brightnest colours were unnatural, way too vivid.

On this one Sony got it spot on, accurate colours, very good blacks and whites. Another advantage of this is how easy the screen is on eyes.

Obviously this will not appeal to people who like overblown, vivid AMOLED screens, so matter of preferences.

Angles are not great, but when you stretch it really, with 2 people side by side I still can have good colours on both.

Shame about the Sony going for the grey theme, would much prefer black and this got some people into "washed out screen gate" - which is simply not the case.
[Xperia Z Q&A, Help & Troubleshooting] trickyhenry:
Pretty sure those saying the screen looks washed out are not taking into acc that the theme is a dark grey. Go to Google images for a color chart. You'll then see the grey. The color reproduction is very realistic. No overt saturation so a more mature and stylish look.

The viewing angles aren't great but then I don't like other people around me looking at my screen so I don't mind. I always look at my phone straight on.

Anyone considering buying.... You will not be disappointed.

Can someone post pictures of UI with some real black theme? not grey...
[Xperia Z Q&A, Help & Troubleshooting] TheSlipperMan:
See attachment - EDIT: Sorry I thought you meant wallpaper, I don't think there is a way to change the colour of the notification bar or soft key bar.
[Xperia Z Q&A, Help & Troubleshooting] Hacker4748:
It's true that the UI is dark grey and that can be quite misleading, also the soft buttons are on a grey background which does not really improve the impression. I have checked using Display Tester as shown in one of the youtube links above and looked for black reproduction. I have also set a pure black wallpaper for testing. The black looks fine up until about 50% brightness, between 50% and 75% it starts getting noticeably washed out. One probably won't mind in bright daylight, though. Still looking forward to comparing with the HTC One.

Would anyone know how to set the background of the soft buttons and the status bar to pure black?
[Xperia Z Q&A, Help & Troubleshooting] StaggerLee13:
Can you take photo, is it also black at the screen? or only as screenshot? :) Really wondering should i buy this phone. Would be my first Android..
[Xperia Z Q&A, Help & Troubleshooting] abd_alazeez2002:
Dude almost all screens have this same problem.

When the backlight is high, some colour became unnatural specially the black.

The screens that dont have this problem is AMOLED, as they don't have backlight.
[Xperia Z Q&A, Help & Troubleshooting] Darkfunnyguy:
Yes I agree with yopur comment

:good:
[Xperia Z Q&A, Help & Troubleshooting] Hacker4748:
Of course. Some more, some less, though. All I am saying that if possible, everyone should check the phone for themselves before buying and that the default grey theme does not serve the phone.
[Xperia Z Q&A, Help & Troubleshooting] thelasman:
Z screen, dissapoints when viewed from an angle.

I can compare with a Galaxy S2: The Samsung gives much more contrast, the Z looks a bit washed out, this exponentely viewed from an angle. Yes sadly enough a very small angle. I will have to get used to this. It is very difficult to get black to look black. it tends to be grey.

It is a bit like a beamer. Very difficult to get black really black. The resolution however is fantastic. No pixel to detect.
[Xperia Z Q&A, Help & Troubleshooting] hebbe:
been to a store this weekend and compared my xperia z to the nexus 4 and the s3. i have to say that i liked the z screen the most. colors weren't as shiny as on the s3, but that's due to the oversaturation of amoled, as told here before. i like the reallife-colors on the z more. the z screen is more crisp/sharper, you can see no pixels (like you can do on the nexus/s3).

when it comes to viewing angles, the nexus and the s3 seem to be slightly better. so if you're planning to wathc movies on the z with your 12 friends, then the z might be nothing for you ;) but if you use the phone for yourself with normal angles, the display will be just fine!

the best would be if you make up your mind by taking a look yourself.
[Xperia Z Q&A, Help & Troubleshooting] Agent_Llama:
The screen clarity is great, but for some reason my other half's Z is much brighter on the full setting and displays better contrast and vivid colours. Really annoyed about it.
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
AW: So is the screen THAT bad?

Pull a backup from yours, pull a backup from hers. Restore backup cross-wise-over and then take hers and give her yours. She won't notice, I suppose :D

On the other hand, how often do you run around with brightness on full blast? Would it be worth the hassle and probable divorce...? :sly:
[Xperia Z Q&A, Help & Troubleshooting] Agent_Llama:
I agree about full brightness; I usually just have it set to the highest auto which is considerably dimmer. As for swapping them, I don't think I'd get away with it! I emailed the company I ordered from and they're sending me a new handset. Will be interesting to see if in fact my display is standard and the other half's is the anomalous one.
[Xperia Z Q&A, Help & Troubleshooting] 3473:
Played around with one today, display was disgusting. Pixel density was nice, but everything else (colours, viewing angles etc) were reminiscent of a cheap £60 phone

Hopefully this isn't the case with the HTC one - one x, one x+, butterfly all had amazing screens.. hopefully this continues and they don't cut corners like Sony
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
AW: So is the screen THAT bad?

Blahblahblah, another one without a clue.

Don't like the display? Fine. Voice it. Put your rants in public. Like another device or display better? Good. Go for it.

Babbeling about cutting corners? Get the **** out. The "issue" or rather fact of rather small viewing angles comes from the high-end top-spec display technology Sony employs in the Z. The technology used is battery friendlier than other technologies but as a trade-off come the limited viewing angles. Cutting corners... You make me mad.
[Xperia Z Q&A, Help & Troubleshooting] lloydbf:
Did you just call the Z battery friendly? :cowboy:
[Xperia Z Q&A, Help & Troubleshooting] 3473:
Lol someone bought the Z and will do everything to defend it. Nothing high end about that display other than the pixel density. Blacks were grey (expected), whites were yellow (disappointing).. hopefully a custom kernel can fix some of this.

I can accept poor viewing angles, but on the model I tested, even the SLIGHTEST movement of the phone would affect contrast.. this isn't good enough for a £500 phone

Can't comment on battery life, but I've heard it's not that great either. They should have used a snapdragon 600 soc which is faster and more power efficient
[Xperia Z Q&A, Help & Troubleshooting] luke997:
That's hilarious :laugh:

Not sure which phone you've seen but certainly not retail XZ.

Blacks are not on AMOLED level - obviously, but they are as good as LCD gets. Whites are white and colours are much more accurate than AMOLED or couple other oversaturated LCDs on the market.

I had my doubts after placing pre-order seeing all the display threads, I'm glad I hold on as the screen is fantastic.
[Xperia Z Q&A, Help & Troubleshooting] abd_alazeez2002:
So your judgement is based from testing a model, how charming.:-/
[Xperia Z Q&A, Help & Troubleshooting] Maedhros:
Here is an objective, scientific measurment of the screen on the Xperia z:

http://www.phonearena.com/news/Scre...ows-almost-perfect-calibration-by-HTC_id39893

It is atrocious compared to the DNA. Not trying to offend anyone, just putting out the evidence. Ppl can read it and choose to believe or just ignor the proof.
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
Did I? I did not. "The technology used is battery friendlier than other technologies" is a comparison to other possibilities there are or could have been. I do not with one word state that the Xperia Z is battery friendly.

Uhm, no. I'll try to show you up and take what you put here and turn it around: someone didn't get the Z and is perfectly informed about the tech inside the Z and what not by looking at it sideways in a store for 10 minutes.

The displays characteristics and shortcomings are well known and documented and illustrated. Even in the wikipedia article describing the display tech. You may - in the scope of this thread - write up your educated findings and your verdict about the Z here. Yet coming here and ranting in a disqualifying manner is, well, disqualifying. If you're not interested in good dev support, go to the locked down HTC One, if you take the Z as what it is, shut up, get one and enjoy it.

The display type technology and manufacturing process sure is.

Regarding the high-end hardware inside, the Z does ok. No comparable device performs significantly better or worse. Regarding uptime the Z is on par with my lower-res, smaller-size less-performant Xperia T and it's superior to my - although that has a deteriorated battery in the meantime, so no fair comparison - Galaxy Note while delivering significantly more power than both. Sounds ok to me.

Strictly speaking the article is about the calibration, not the hardware. The limited viewing angles come from the hardware itself while the presentation of content is software. HTC obviously did a better job with that, granted. I find it peculiar, there seems to be either a massive divergence of the screens perception even among professionals working with graphics and images or there must be an appalling spread within the different devices for one part and the demo- and pre-production models on top of that. My screen exhibits small viewing angles but otherwise it does really well and the screen is very nice to look at, the presentation is really nice. And I'm usually not that easily satisfied, especially not for these kinds of money spent.
[Xperia Z Q&A, Help & Troubleshooting] 3473:
This is hilarious, the fact that you're getting so butthurt over it proves that you're aware that the issues are there

I am merely stating my opinion - based on what I saw (poor display, last gen soc, glass) I wouldn't waste my money on it. I also remember that the battery depleted by 12% in a few minutes, which was another concern

Hopefully the new C670X Sony flagship out soon will correct some of these issues
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
I'm not butthurt as I personally like the device I bought very much. I'm glad I got it, it's a joy to work with. It sure has some niggles which I notice from time to time but which I'm comfortable living with. I'll list them up if anybody wants me to.

Yet you annoy me with rather uneducated utterances and bumper-sticker wisdoms. You don't have the Z, you don't work and live with the Z, you don't like it and you will most likely not get it. It's unlikely you know so much about it then as you claim you do. And as you don't like it, I don't see why you invest so much time in it. It seems to me, the best thing to do is to leave the Z forums and go to the forums of the device you intend to buy and educate yourself on that, no?
[Xperia Z Q&A, Help & Troubleshooting] Paul5015:
I think a lot of the issues are down to poor calibration.

We have a couple of units here at work and they're not the same, they should be. One has a far higher colour saturation level than the other.

A review is usually based on a single unit, who knows what they were looking at.

I had an HTC Evo 3D and a Sony X10 before. The display on the Z is awesome in comparison. I looked at the amoled displays and whilst the contrast was stunning the colours were over saturated and unrealistic.

The resolution of the Z is beyond anything you'll ever need. It's bright, the contrast is great and the colour saturation is perfect (on my unit).

If you point the phone at a blank wall in a darkened room you can see the light emitted from the display is focused into a cone of light about 35 degrees wide. This has to be where the user will be looking from in 95% of the time. It's not something I've noticed in use, I had to find out about it here :)

I get easily two full days with the phone before needing a charge. I'd admit the older phones have conditioned me to turn stuff off when I'm not using it. I don't use the Stamina mode, no need. That said, if you turn up the screen brightness and stress the CPU, it'll use about 1% a min.

I'm really happy with the Z it's a great phone. If the HTC One has an even better screen then that's great, I can’t wait to see it. It sounds as though they've don a better job of calibrating them for sure.

P.
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
That's in fact what the article says further up. The hardware itself and it's capabilities are probably - I can't judge, I only have my device as a reference - awesome. I mean it's cutting edge display technology, it should be awesome.

Interesting. Can you check whether those devices were manufactured in the same place/country and from the same batch/manuf. date for me or if they differ? If different manufacturing places would produce SUCH different quality devices, that would be quite a thing.

With the Galaxy Note I remember people were claiming that Vietnamese Notes were the best and I believe Japanese Notes the worst :p Don't remember exactly though.
