tweaking the CONTRAST? - Xperia Z Q&A, Help & Troubleshooting

Hi, i recalling a few months ago about a post in xda, people said that a possibility to tweak the CONTRAST for our Z or ZL screen, to improve the viewing angles. NOT the white balance settings. Someone mentioned abt tweaking the KERNEL values or some sort, just like the improvement of screen colour that Sony done from firmware .350 to .434. I am very sure that if we can tweak the CONTRAST values, viewing angles will be solved. Can any dev help?

Till now we don't have a capable developer to do it.

Just take an example Xperia Ion, although the screen is not as premium as our Z or Zl, the contrast is great! hopefully some Dev can put some attention to it and our Z/ZL would be flawless, as good as the Z ultra's screen!!

Doomlord is currently working on gamma controls.

how many layers does ion's screen have and how many the Z (glass thickness protectors, etc.)
more thing on top means more light distorsion and colours fade sooner. anyway why you want uber viewing angles

Oh really? Wow, thats worth looking forward to!! :good:

[Off Topic] How the LG Optimus 4X compares to the Xperia Z

Some of us here really like the Xperia Z and want to switch , here is a video comparison

the 4X's screen is way better in terms of color reproduction

Really? 4xx PPI vs 312 ppi? And on top of that Bravia engine? I don't think so. The Xperia Z is in another league my man. Yah the o4x is an awesome phone, but there's no way it can compare to the Xperia Z. But I were to get one, I'd opt out for the ZL.

Yup, really, 441 ppi doesn't have anything to do with color reproduction, Bravia Engine 2 could, but here it doesn't...and Xperia Z it is another league, that's why 4X is AWESOME
Just look video from 2:40 wow XZ is owned by X4, Sony take my deepest sympathy...:crying:
Only your eyes will tell you how gorgeous is the screen on Xperia Z...
There's nothing to compare.
The Z is light years ahead in every aspect if you try to put it against our 4X.

Actually, that's what I expect. It's brand new while our 4X is nearly a year old. Things change fast these days. Three years ago the best you could get was 900MHz single-core with 480x800 screen. Two years ago the best you could get was the 2X with dual-core, still with 4" display in 480x800. And it was until last year that the quad-core phones and HD screens were introduced. So it's the logical next step, even higher performance and even better displays. What doesn't mean our phones are obsolete now. Android can't even handle four cores properly.

Well my eyes told me, looking at this video, that Z is not so spectacular. Even more it fails short in color and brightness department.
Or I should use my ears to hear (look) what daddy Sony has to say about it's child Z?!?
And there is nothing to compare, man R U SERIOUS?!?
There are great screens out there and they are comparable!!!

Well... You saw a video of a display,wasn't your eyes.
So,what i said is right.
Again,there's nothing to compare.
Even with your arrogance the Z still light years ahead and,if a phone is better,this makes our 4X worse?

And about "sense",i prefer UXP :good:!
The only thing blind is your nescience.
Videos doesn't do any justice to how beautiful the Xperia Z will be. Hell, my co-workers HTC Droid DNA has a 1080P display with 440PPI...and my O4X doesn't even get close to how sharp color reproduction is.
seems like ips panel is still good on color reproductions

[Q] xperia tx or t?? i dont know witch to buy! help me :D

is there eny diferences in hardware??? i mean, at least for me the xperia tx looks better because its thiner and has a biger dispay, but i read in some post, the xperia tx procesor is diferent then the xperia t. another point, i like to use rooms and addons, i was a xperia S user so, i wanna buy a phone that has the same facilities to install all ths things (sry about my english not my native languaje xD )
xperia tx is better all around except when it comes to faster ROM support.
there are more people that have the T, but the TX still is a better phone because it has:
slightly bigger screen (? i think)
same processor
better form factor
removable battery
feels much better
doesn't have the body paint issue
The Xperia T and TX have the same screen as far as I know. It's just that some sites round the screen size (4'55) up to 4'6 or not.
The TX is slightly taller and wider, and a bit thinner, but on the whole you probably wouldn't notice the difference.
TX's main advantage is the removable battery, but you pay a price: less capacity 1750 mAh vs 1850 mAh of the T.
Also, as Fuzalert2k mentions, most devs have the T, so rom variety and development is better.
AW: [Q] xperia tx or t?? i dont know witch to buy! help me :D
i think the most important has been said
i have the xperia t and i'm very happy with the device :thumbup:
Sony Xperia T Black
4.1.2 JellyBean
9.1.A.0.489​
thanks dudes now i have another problem
hio, so thanks i get my new xperia TX jejejeje beautifull! love it! but i cant root it!! maybe you know how to plx help me ty
OH !

It's not that rare, you just have to search a little more in Indonesia porducts
In general, both of them are good.
About design of them, X-T looks manly and stronger than TX ( in my opinion)
And XT has water resistant but cant change battery.
But for me, i see the T screen is not good as TX. Its default brightness is to bright. So it does not display true colour like TX. It shows the black colour like grey. Sometimes it display the colour like super amoled.
And more but i dont remember all.
Sorry for my bad English.

[Q] Xperia Z - Screen Calibration

heard a lot that Xperia Z is washed out & poor contrast , this was added up with "Screen Calibrator" software , the question is - IS THIS SOFTWARE REALLY COMING ? IF NOT WHAT CAN BE DONE TO IMPROVE CONTRAST ?

check the these pics that compared with flagship of Samsung S IV, S III with Super AMOLED Display
Just amoled will become darker and lcd tech will become brighter
Found a VERY interesting video. Just shows what the Screen is capable of!!

This has also been bothering me. Back when I was using the nexus 4, i was able to flash a kernel that fixed the screen 'washed out colors' problem. Is there a similar fix to the xperia z?

yeah the software will come, and will be under settings display. I recently updated my japanese version of the xperia z and the screen calibration was part of the update as well as a fix for the black screen.

Display screen calibration

Now that I realized that our phones do not come with the display calibration softwares like Z and ZL, still I'm looking for some way to fix the annoying low contrast and washed-out colors on my T. Is there any alternate software or app that can do that?

Bravia Engine...all time??

So I know that our display is fading when it stands vs HTC, LG, Samsung screen but if we make Bravia Engine always ON the situation changes, the screen could be equal or maybe a little bit better than others with more power consumption.
So its this possible..to have bravia engine in games, homescreen, anywhere in sistem? As I read on the internet I didnt found an exact answer for this question.

Theoretically it would be possible but the battery drain would be enormous ATM, unless Sony delivers some tweaks!
That's probably the reason why they haven't done.that in the first place!
Sony.would be better off with an oled display, tweaking it and sticking the BE2 ENGINE or x-reality into that, saving battery consumption. Then they would be unbeatable for a while!

OK its quite late , but I can suggest you some alternative try it and lemme know..
google is your best friend , search for Screendim.apk and install it
enable it and set the bottom bar ( contrast ) for about 60% and the brightness on top for about 60-70% and now tell me how dark or colorful your screen looks
this defnitely works.. not perfect but close to BE alwasy ON types..

Fanboy alert. You didn't see very grey black, fogged colours, bad view angles etc? So you have some problems with your eyes (or just fanboy). Even 2 years old phones have batter screens than Z.

Nope. Neither my Xperia S nor my Xperia Neo nor my Nexus 4 nor everything i've owned had a better screen.
Maybe there are some people on the world who like natural colours, becoz after looking at a amoled display my head hurts.
The display of the lg g2 is the only one which impressed me though, this is miles better, but nothing else.

If you display some screen calibration patterns while using bravia engine, you see how bad it is for fidelity. It just oversaturates, tints, and destroys detail in brighter and darker areas of images/videos.
If a phone has a screen of 300/1 contrast ratio, there is no way some software can improve this, it only can put some make up but at the cost of some other things, just like LCD's are doing since the beginning with dynamic contrast and all that bullsh*t, where you see skin become shiny bright and where there used to be a dark grey shadow over a black background, then it becomes all black and no shadow.
BE is the first thing i disable in all my Sony products, and its equivalent in any non Sony product.
I think that our screen without bravia its complety UGLY! :-&
I never had any issues with the colours on my device. Infact I prefer them this way as opposed to colour popping and extra vibrant. Infact I turn down that setting on my LCD monitor. A friend of mine did a side by side comparison against his Samsung device and the 1st thing he notices was the colour was more toned down then said he actually preferred the Sony display. Point is some ppl like the toned down visuals and others like them vibrant but funny how as someone says they have no issue with the Sony display they are labeled a blind fanboy.
As for viewing angles, Also never had an issue with them due to the fact that I always take up my phone when I want to look at it (always, its a habit of mine) and never just glance at it while it is on a desk or anything like that.
Xperia Z Screen is OK, i have been using it everyday since launch date, viewing angles may be low, but that is something i forgot completely in everyday use. Screen brightness is more than enough, contrast is ok, and visual fidelity is great (as long as you have BE2 deactivated).
For people saying there were better screens two years ago, please point me to a device released two years ago with a 5" FullHD screen with better specifications.
We all know the XZ screen, today, is not one of the best FullHD screen on a smartphone, but it was the first released.

I don't think they need a doctor or anything, it is a matter of taste, there are people who like viewing screen with oversaturated colors and overdriven contrast just because it is more eye catchy, for god's sake they even ported the bravia engine to the galaxy nexus, and there are people who even enjoy it, if the nexus screen weren't oversaturated enough... let's oversaturate it even more and add a lot of detail loss due to contrast overdrive by BE.
Oh, also forgot to mention, "nits", why the hell would we need a screen with a gazillion of nits if at the end of the day we are all using the brightness bar to decrease it to save battery (or using the Auto mode), at the end we all are viewing the screen with about the same luminosity, it doesn't matter if our screen has 10 or 8.000.000 nits.
