Xperia Z4 Tablet White Balance - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Anyone have a good white balance setting for the Sony Xperia Z4 Tablet? I currently have it like this.
R - 144
G - 137
B - 0
Anyone have a setting that shows good whites? Been looking around but I can't find much of anything.

This is very much dependant on each individual panel. You often see them being manufactured by different companies, like Sharp, LG or even Samsung. And even when they would all be of the same brand, there are differences, so if you want to do it absolutely right, you should take measurements. Calibration software with a colorimeter, woukld be the way to go. I'm sure something is possible on Android.
I'm running the stock white balance, seems pretty good to me. It's really properly white looking compared to my Samsung Galaxy S6's Super AMOLED screen, which is really yellow-ish in comparison.

When I first got it, I thought it was fine. But the more I used it the more I started to notice the Blue tint. It has a very cool temperature to it. After messing with it for a couple days I found a measurement that looks more natural. Don't get me wrong the display is beautiful beyond words, but the white balance is off. With almost every until I've seen and heard of.

Screen problem: slightly visible moire-effect like pattern

I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?

Screen looks washed out

The colors looked washed out. hey, I just got my z ultra from singapore and everythin seems too bright and washed out.
I'm on version .510

Yeah, the screen definitely doesn't look washed out on a properly working unit.

The Ultra's screen is nothing short of breathtaking, you've got a defective unit.

Turn off that optimised backlight under display then you'll see how good the screen can be!
You know, I went back and forth numerous times between having the optimized backlight off and on, and I could never tell any difference. I'm convinced it's the placebo effect making people think they see a difference.
If you're coming from Samsung, then you will see a difference, this screen has much more natural colours and it takes a little getting used to.

I agree with you 100%, I am from Samsung Note2 and the screen does look a bit dull especially with white backgrounds in SMS app or others.
One strange thing that the center "horizontal" area seems to be perfect white while the top and bottom of the screen have a brown / yellowish shade to it. This has been irritating me and I am trying to ignore it
I got mine just last night and absolutely love it other than this small issue with the screen. I wonder if I need to take it back to Sony CS for a comparison with another set?

I agree. Was comparing iPhone 5 and samsung note 2 with z ultra. The z ultra seems pale in colors and doesn't have good contrast/black.

after some comparison
I found that it's washed out indeed,, but ONLY IN GOOGLE PLAY
(compare the green button "apps" to some green app icon on home(exp Line) back and forth,,, it's really easy to see that the green in Google Play are washed out)
I dont know what kind of tweak sony done to google apps but after some test and comparison,,, it seems to be the case
anyone agree?
---------- Post added at 05:56 AM ---------- Previous post was at 05:19 AM ----------
ok,,,,after messing around with it now i found not not only Google Play is washed out
other google apps are also washed out like gmail and such,,,,,,
Now that you mention it, the Gmail app on mine does seem to be a little...I don't know that I'd say "washed out," but for sure the text looks less contrasty. Images don't seem to be affected, though, and the display is brilliant everywhere else.

after some further comparison between the same pic file displayed on different displays(including my desktop;screenshot'ed the google play interface on different phones and compared it on my desktop;etc)
i found, at least this time - -! , i think rather than the tweak by sony,, it's actually that our eyes got too accustomized to the over saturated green on samsung AMOLED devices,,, the green of google play/gmail/etc compared to samsung device did look washed out,, but thats becasue that's the accurate color google initially intended,,
Thing is, I've never owned an AMOLED phone. :/ Anyway, it's the text on mine, not images.

id admit im obssessed with this problem and till now done many comparison,,
(detailed in the thread i made: ,,,http://forum.xda-developers.com/showthread.php?t=2472114)
and got to the conclusion,,the screen is indeed wased out , and colors are "light"/less vibrant,, but it wasnt due to defect but rather intended by sony
Just some food for thought.
I am sure you all realise that you are trying to compare different types of screen technology? Let me give an example to help perhaps?
Plasma V LCD or LCD-LED TV's. What produces 'the best' picture? Non of them, they are different. Since the LCD TV has been introduced it was supposed to be the demise of the 'old plasma' screens. Not the case at all and many top brands still make plasma screens that are superior in some aspects to the newer LCD- LCD-LED group.
I am afraid to write that it will come down to choice and preference. I went from Samsung screens to Sony and back to Samsung in terms of phone. I didn't want to as I have a preference for the type of screen Sony produces. I shall be keeping my Xperia 10.1 tablet as the screen just amazes me. The screen on the Note 3 that I now own is back to these over saturated colours and odd definition and contrast. No choice for me as the Ultra is just too big so I had to go back to Samsung but....
Its rather folly to even try and compare an apple with an orange just the same with different screen technology. One can purchase a lemon in any brand. I think to write that the ultra screen looks "washed out" is difficult as it could be a lemon. In general the new screens coming from Sony are very vibrant and more importantly realistic in colour reproduction and tone.
Choice will be ones buying strategy. Manufacturers have been trying to kill of Plasma screens for years but cant as they have something other screen don't.
Regards
I have to disagree. Those tech are replacing older ones cause they obviously produces more correct representation of colours and faster refresh rates. Except plasma which still produces one of the est colour, but unfortunately cant be made in higher resolution because of its inherent limitation. I have to say my preference has always been about correctness. I was hoping someone would say its a defective unit and the good unit would produce display similar to iphone or samsung. But i guess my upgrade have to wait until i am aure the display is at least as good as the IPS-LCD which iphone uses.

You begin by disagreeing then write exactly what I have written
No problem.:highfive:
I have to say, I never had an AMOLED device, but I love the colors of the XZU.
It doesn't look washed out at all, the colors are indeed a lot like the colors on my IPS PC-monitors in color-boost modus (which means the colors are even more colorful than they are normally).
There are devices where the colors look washed out, e.g. the Nexus 4 and 7, but definitely not on the XZU.
If you think the colors are looking washed out you either got a defective unit or you have a very strange impression of what colors should look like.

Mediapad M5 pro panel brightness white background

Does any tablet owner here of M5 or same family tablet, has noticed if one of your display has an edge or sideline that is slightly slightly darker, during using a fully white background?
On my m5 Pro I've noticed that with a fully white backgroud, I do have an edge, close to the left bottom corner (holding the tablet horizontally) that is slightly gray rather than the right side. Off course that: if I'm rotating it, then it Will happear to the top instead.
If you don't stay there and looking at it for a minute, you don't notice it. But if you look at it and compare to the rest of the screen or other side, then you'll see this small difference.
Do you have same issue? Does it is an IPS display issue?
Ah! It makes it only with the White. Only the White. Other colors comparisions are fine.
Looking videos, pictures or anything else that does not push the screen to a very high density white in that side, it's fine.
You can try to see if you're having the same of opening the cleaning chache program, where there is a lot of White all around the screen. There you can watch side by side and every corner... and you can try too see if somewhere do you have a slightly white difference compared to the rest.
But as said above. Only white make this.
Videos, pictures with same colors side to side are fine. It's all about the White.
I've contacted the Huawei assistance trough Phone and they said that is normal and panels might do this, and if in doubt, I'm free to go to the Local official technical assistance in my town to have a confirm for it .
So I've done that! I've moved to the Local technical assistance and the technician told me that it might happens and it is not worthy of a repair, because changing panel might not solve the problem as this slightly slightly brightning difference might show on another side. Has more sense to wait if in these 2 years something going worse and repair it over warranty.
It's hard to see this difference of White brightness, and I've noticed that just because I'm a really fussy guy and ... off course I don't spend my time on surfing on the menus. It's also a post to understand it these kind of IPS panels may encount these issues.
Anyone here is experiencing this thing? Or are you watching all the sides of your tablet to see if do you have it aswell? :laugh:
It's called uneven brightness, and reading notebookcheck's review said that it is above average. Seems you have received a dud, but it's likely within tolerance im afraid.

Are you sure It's a dud? In a FB group a guy said that he's even worse on his 8.4 because he has it all over the edges . And on a previous M3 he got, there was an even worse side with less brightness. And so He returned the tablet.
In my case, it's so soft that you don't notice it at all. You do have to search for it. And it happens only with the White.
It the technician in the store told me it's not worth a replace the panel, this slightly brightness might happpen and same issue might happen in another side, nobody knows. I wish to beleive him . Why He would had lied to me?
Anyway I've read the m5 review and they are showing the characteristic of the brightness all over the display. Yea, it is seems a trait of it, and a 0,25 cd/m2 is barely perceivable.
What's your opinion?

my M5 is perfect, no noticeable differences in brightness anywhere. Notebookcheck said that the 8 in model has poorer display anyway.
If it's not noticeable in normal use then it's fine.

Is there any reliable software for Android to do the same thing done by notebookcheck and testing the brightness? Like this:
I've checked that one on playstore, but I did not find nothing.

You need something that can detect the brightness, usually expensive hardware that connects to a windows machine. I think they start at around $500 or so. You could rent one i suppose. (if you could find somewhere or someone!).
But yeah it needs hardware.

What did you decide? I have one side that is darker or M5 10.8, not a pro version.
Should I try to replace it? It does not bother me much and I read here that there are more units, that come with more darker sides/edges.

The problem for me it's just a little and not worth a change for defect.
Because a repairing stores told me that quite always somewhere that little little darker side happear. It's not guarranteed that with a replacement it would not happear elsewhere. It's happening only with the White. Normal use the tablet is fine.
It's an issue of the IPS display, expecially large displays. That's Why i love the AMOLED all the way.
Technician said it's not for a change/repair, exept if it is gonna go worse.
So I'll keep it. Does your problem is so noticeable?

Thanks for help.

Did you had this issues also with other colors? If you were watching a movie or working on a picture was noticeable?
For me it's only the White, but you do have to look for it. It's same issues that have low/mid ranged TVs.
Not worth a change or a repair. Because it can ne elsewhere.
Does it is the same for you?
Keep us updated.

Yes, there was also a problem with other brighter colors. It was noticable only when browsing, but that's mainly what I do with a tablet. After a while I started searching for that darker side in various apps/colors, instead of enjoying a tablet.
Today I got a replacement. The screen looks more or less fine on the sides/edges both with white and other colors.
my m5 pro 10.8 is perfectly in balance.
iv´e tested with a white fullscreen wallpaper on max. brightness. everything is ok.
also other colors are fine.
...
every M5 screen has it. I had 3 pieces, each one had a near the status bar (battery, hour) visible only at a sharp angle. If you do not see it, you look at it badly. I stayed with the first copy. These two still had dead pixels. This is the construction of ips.
yeah i have no issues on mine, full brightness and looking from sharp angles doesn't make much difference at all. Slight brightness changes maybe, but same happens to any screen.

S10's OLED Display Is Actually Better For Your Health

One interesting thing that most people aren't talking about is the fact that Samsung's new displays are actually TUV Rheinland certified for significantly less blue light emission (advertised 42% reduction), while still maintaining optimal colors and picture quality.
To me this is a huge selling point. Most people probably don't care, but blue light is shown to cause significant eye strain, and slow the development of melatonin in the brain., destroying your sleep quality. Just curious on everyone's thoughts about this.
Here's some more info if anyone's interested;

https://news.samsung.com/us/samsung...rp-reduction-blue-light-emission-oled-panels/
Samsung discussed it at their event. Reviewers/Youtubers and tech sites rarely comment on blue light emission. You'll come across more articles on how to kill Bixby! The Honor 8X was certified too, but few speak about it.

Didn't know about the honor 8x. Is that also a Samsung display? I'm curios to know exactly what manufactures use Samsung displays aside from Apple.
hope this doesn't mean the screen will be more yellow. I hate that. loved Samsungs bc of their nicer, bluer screens tbh. my pixel 2 looks nasty compared to my note 9.

Blue-light filters usually make things yellow, but I checked the s10/s10+ in a shop and the display is PERFECT, the white levels are incredibly pure and it looks cleaner than my XZ1's IPS which I thought would have unbeatable whites when compared to oleds, that's no longer the case.
I always hated OLED but Samsung found a way to reduce its drawbacks while creating a super accurate panel, if you want to buy one last AMOLED device while waiting for Micro-led to be a thing in mobile, this looks like a very wise choice.

Didnt even know about micro led until now. Does look very promising. Hopefully we see in on the S12 if not sooner.

They're still trying to shrink it for the average TV size, I hope it will come soon.
Did some more research on the Honor 8x, it appears they are advertising blue light reduction with their "eye comfort mode" which tweaks the colors you are seeing. While on the other hand, Samsung is pointing out the 42% reduction from previous OLED's still maintains the same colors you're seeing. So based off that, the S10 is capable of reducing exposure without software tweaks.
It also appears that out of the box, the S10 is defaulted to the "Natural" color setting, and provides a "Vibrant" setting, which does increase color saturation. I wonder if the higher color setting changes your exposure by much...

Then the Honor 8x's solution is nothing more than a software re calibration tweak, I'm glad the S10 comes with a hardware solution that doesn't impact viewing experience.
But yeah using Vivid mode will increase your exposure to blue light depending on the displayed colors, I wouldn't worry that much, it is in no way as dangerous as the exposure to TVs, Desktop monitors or even daylight.
Can someone link to a bluelight study that shows its harmful. I lost my ebsco access when I left college. I always thought this was an overreaction. I've been staring at cool temp computer screens since the 90s, and my recent eye exam says my eyes are still perfect.
I've found the press release, but no peer reviewed papers.

Glad to know I'm not the only one. I even wear reading glasses with blue light filter due to my extreme light sensitivity, so yes, totally big deal for me too
Pwm is for losers. Now Sony is also on the oled bandwagon.

Is the TAB S6 AMOLED screen really that bad?

So I currently own a Tab S4, Note 10+ and Note 8 and I've been impressed with the AMOLED screen. Today I got a Tab S6 and I'm severly disapointed by the screen quality. Compaired to the other AMOLED displays, this looks like an old LED panel, pretty bad quality no deep blacks, low contrast and the same image looks totally different over the two Tab screens. Additionally, when something comes up that blurs the background, the effect is more like a severly reduced pallet count rather than the normal blurring effect.
Is this normal for the Tab S6 or is this a bad unit?
I've also had trouble with the under screen finger print scanner not registering fingerprints, so I'm thinking faulty...
I haven't had any problem with the screen nor the fingerprint. Might be a bad unit.
No problems with mine...Everything looks great. Just a thought...When I first got mine up and running it looked a little dim as you describe. I went into the settings and put it on vivid and it lit up and was a totally different look. But if that don't help then probably a faulty screen.
Come from the tab s3 have an s10 plus as my daily phone looks just as good as the s10 plus in my opinion.
Nope it isn't
I did try that, but even with vivid on it still looked washed out

Yeah sounds like a bad screen....I would take it back.
The quality control is awful, I've had three which I've returned due to uneven black levels.
Samsung are obviously aware of the issues with the displays but they don't care because many users just don't complain about it, or don't know what to look for.
Apparently there are a lot of people having uniformity issues with their devices and there doesn't seem to be one free of defects. As always it's the OLED lottery! Exchange until you're satisfied.

We are all techies in this forum the average user would probably not even notice if the backlight was uneven especially if they have come from an old non OLED device I think that's probably part of the issue

Totally different look that gnus hooked people up on, and milliards of nobbs saying that amoled is way superior tehnnologi. Now it decided to turn around and present natural colour palette (with uneven wrinkled display to boot), i agree that it can be not so good to look at it after vivid

Im in the same position as you and I already bought 3 Tablets that had unsatisfying black levels. I feel bad for buying and returning them and I am asking myself if I should keep trying or just give up.
The OLED display on my note 8 looks so smooth and even. I wish I would find a similar tablet display.
Did you finally find a unit of the Tab S6 that has perfect blacks ?

Unsatisfying black levels? How is this possible? Black should be totally black LOL xD
Do you mean the grey color or something near black? Or you guys really talk about true black color? ( for example when booting up the device )
True blacks are fine, but it doesn't handle mixing very well - Compression and noise is easily noticeable at that point.
For example : The blacks in this video look terrible and Compression is easily noticeable when mixing the Vegas sign and the landscape of the city.
But in this video, they're perfect - The only noticeable problem in this video for me is when the camera is panning the planet and mixing black, purple and blue - at which point some minor noise is present but the rest is fine.

No, I'm not concinved there are any perfect displays. I still have one corner that's darker, honestly this experience has put me off Samsung. As soon as there's an Android tablet with better specs I'm done with this, I might be done with Samsung to be honest, the punch holes in their new phones are horrible and they're overpriced..
What's the best way to check the uniformaty of the panel in the S6? I don't believe I've got any issues but better safe than sorry!
Tab S4 much better will return the s6 I just bought as you can see grey in blackboard in so.e videos which you don't on the tab S4. Hopefully replacement will be better.
