Clearing up the display issue of the Xperia Z

[Riyal]

Plastic tend to flex while glass is fragile. Sure glass could survive a drop on a material where it is harder but I highly doubt it if it were to be dropped on a metal/concrete surface. Impact would create a deep shock on it's body and I don't think any glass could survive that. Since glasses are pretty solid and doesn't really have any shock absorbent property on it.

Maybe we would have to wait for a drop test video of gizmoslip for the Xperia Z/ZL

Hi! If you don't mind could you try installing this software on your Xperia Z?

And see if you can fix the saturation like they say.

If you can then I can confirm that the issue is within the ROM it is using and not in the display nor the gamma values defined on the kernel.

Yes please someone with a z try this out

2nd that, this could be a big game change!

Seriously anyone with a XZ should try this and post some results too with screenshots!

This will be the deal breaker for me......patiently waiting some feedback about this, i like the screen, but for 2 years?....not so sure......i got my One X on a 12 month contract and was hoping to do the same with the Z.........but none about.

If this app makes no difference whatsoever then i will probably be pre ordering the M7/One when details come out about contracts.

Indeed, although I'm kinda worried about the battery life of the M7 since everyone says the One X has a rubbish battery life. It could be a trade off i'm willing to make as the display is as step up from what I have now, would be far more difficult if it was a step down

One X running custom ROMs give good battery life.....i regularly get 2+ days out of mine, light to medium usage.....in fact i have had over 4 days from my battery, only 2hrs screen on time, but still, good battery stats can easily be achieved. I am not a heavy gamer, but once i initially got over the "new phone" period with my One X, the battery became easily more manageable, and i would expect the same to be true for the M7.

Also the battery should be quite easy to change for one of a higher capacity, as many are now doing with the One X, changing the battery for the higher output one from the X+.

Tried, but the best way by far is default (without the app). Changing any value just decreases the contrast or throws off the colour balance.

Thanks, in the end it would still be possible since the bravia engine manage to get more vibrant colors from the display. sure would have been nice to get that without lo level trickery

Bravia Engine just increases the saturation of images.

This actually is a good thing. It means that the Xperia Z is a nuanced display that doesn't do a cutoff but actually is capable of displaying all the colour gradations properly. The display is fine, I don't know how many times I have to keep repeating it. The only 'problem' with the Xperia Z is that the UI uses a lot of greys, causing everything to look a bit dull, especially with higher brightness settings. Colours are pretty deep and accurate.

Yeah I have to see it my self, some people think that my TV looks dull while it is near perfectly calibrated but these days some people are used to highly over saturated un natural color palettes. It's just like with food, eat enough highly salty or sweet food and every thing else seems tasteless

Exactly. I work on a Vaio Z with a very accurate colour reproduction myself, a display that has been praised numerous times for being very high quality and I hardly notice any difference in reproduction with my Xperia Z (without Bravia Engine), unlike all other phones I've seen before. I'm very pleased!

I'm going to head to the 3 shop in Newcastle today to have another play with the device. This screen issue is driving me up the wall!

Really? The only detailed colorimeter analysis of the XZ screen that I've seen wasn't exactly flattering. See slides 5-12, here: http://www.phonearena.com/news/Scre...ows-almost-perfect-calibration-by-HTC_id39893 The colour temperature swings all over the place as you move across the grey-scale (and is, on average, too blue); and red and green primaries are decidedly over-saturated (the Butterfly does a far better job of both, but is a bit weaker in terms of gamma accuracy).

Reviews consistently point to a poor black-level, too; for example: http://www.gsmarena.com/sony_xperia_z-review-887p3.php or here (third photo): http://www.frandroid.com/test/128142_sony-xperia-z-test-smartphone-android/3/

I think it is clear that the z uses the lesser screen tech, but perhaps also less power hungry.
For me the question is how much worse is it, if it is a a big a difference with the xt I would be disappointed. But than again if the leaked specs are true of the m7 it would be a very power hungry device with a relatively weak battery and that could be the deciding factor for me.

It was mentioned by a member on this forum who has the T that he/she could see little to no difference when comparing both devices. Have to say I was somewhat disappointed in hearing that.

ZL does use the same screen as Xperia Z and what's economical IPS? If you're talking about e-IPS it's Enhanced-IPS not Economical-IPS. There's no such thing.

Also isn't e-IPS made by LG? And the display here isn't from LG but from sharp.

As you can see in the document it is a LTPS type of panel.

Panel Low-temperature poly-silicon (LTPS) TFT

LTPS is a description of a manufacturing process, not a display technology. Low-temperature polycrystalline silicon can be used to make different types of screens – AMOLED as well as standard LCDs. It’s a way of creating tiny silicon crystals that go into making the pixels of a display.
I guess samsung use LTPS to make the flexible amoled display.
the LCD family are TN, VA and IPS and the Xperia Z/ZL probably is a kind of e-IPS display because pro and cons are typialc of this display family.

this one has even more detail, it's in Russian but readable with translate.google.com

I should note that they report a contrast ratio of 570:1 nearly the same as gsmarena first reported than changed it to 700:1.
Also they say that the screen of the HTC butterfly is miles better than the Z, but again they would choose the Z over the butterfly. Almost every review says it's the best on the market so it must do allot of things right to get that label in spite of it's sub par screen.

Screen looks just as good in every photo apart from the extreme viewing angle on that site though?

EXPLAIN why in chrome, whites don't look white until you turn the brightness way up.
But by turning the brightness way up, blacks no longer black, but all washed out.
and vice versa when you decrease birghtness.
The display is washed out, I don't know how many times I have to keep repeating it.
