Screen gamma and black levels! - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

Hello everyone ,i recently got a z3+ and i noticed that the black levels of the screen are pretty bad...coming from an oled display i was expecting some diffrence but not that bad...I watched some movies and in the dark scenes it is very difficult to see the picture ,everything looks the same and you cant really see the characters or the background ..its a mess especially in daylight conditions its almost unviewable.Cranking the brightness all the way up helps a lot -again in very good lighting enviroments/outside/daylight i cant see a thing in dark scenes- but then the black levels are too bad almost grey not black..
I also had a z1 compact which i dont think it was that bad, i'll try to test them side by side...
So i was wondering if a have faulty screen or something but i would like to hear your experience ...
Overall its nice screen bright with nice colours etc..but the black levels are a dissapointment in movies/videos..
Also i have disabled all screen enchanments (x-reality etc) and my white calibration is 178/162/37 RGB
Based on this review i was expecting more...

Blacks are pretty good in my opinion contrast ratio is brilliant for a ips. But this may come from you're eyes trained to a OLED screen. It's like my TV I have a lg OLED in the living room but a led in the bedroom and now I'm seeing grey instead of black :silly:

Here are some photos of my screen's blacks ...taken at 100% brightness in a 100% dark room ,all screen enchanments off, showing the same black level block picture in all 4 photos...i tried to adjust the camera exposure to make it look as close as what i was seeing ...as you can see it actualy can lit the desk under it and there is massive light bleed (if thats the correct term) out of the 4 corners in low viewing angles ,it actually creates a shape of X of light in a surface...Thats all please try it too to check out your results so as to know if i have problematic screen...

[Q] SGNote unnatural colors?

Since I can't see an SGNote in a store yet, curious if the SAMOLED's less than natural colors ever bothers you, they seem to bother me on the lower resolution SAMOLED phones but a bit less on the same res but lower pixel density Tab 10.1 screen (however I prefer Transformer's IPS for a tablet)? -Thx
P.S. - I've heard mention in video reviews that the SGNote does have better color calibration than its other SAMOLED's handhelds.
http://www.mobiletechreview.com/ubbthreads/showflat.php?Number=41813
"Blacks are extremely deep and colors are richer than life, which is typical of Samsung's Super AMOLED display technology. For this high end phone, Samsung spent some time calibrating and tweaking it, and the blue color cast found on other Galaxy phones is at a minimum, and pure black images are pure black with no banding or light patches."

There are three color settings that are select able by the user. They go from very saturated to about normal.

I didn't know that, cool, I'll look into that, if anyone uploads a YouTube video I'd like to see if that shows up..-Thx
same as computer monitor
i was shocked at how different the colors where when i got my capitvate. unnatural is the only way to put it. took me a long time to get use to the pumped up color amoled screen. (certain colors are increased because that is ones your eyes see easier making the screen pop) so when i was thinking of buying the note i had read that samsung gave the owner the choice to change that pumped up look to a more natural scheme i was thrilled. the lower saturation of color feels more closely to regular lcds. when i hold the phone next to my high end computer monitor with the same picture they are very similar in hue and saturation. although sometimes when i am showing off the big screen phone to friends i switch to the standard amoled setting (because the colors pop) i usually choose the lcd type setting for everyday use. hope this helps.

It does help, thanks, how is that color setting changed?
P.S. - Even on my newer Samsung TVs, when someone with blue eyes comes on the screen they can look fluorescent fake giving it a sci-fi vibe that can look ridiculous!

Zedomax did it http://www.youtube.com/watch?feature=player_detailpage&v=RsmDvvckt6k#t=1096s but ideally still would like to see it in person. The higher res screen must help as the colors are not bothering me like they do on lower res SAMOLED screens. I'll check out the 720p SGNexus in person even though I don't think it has the SGNote 3 color settings ("Dynamic, Standard, Movie" in Settings->Display-Screen Mode) that provide more user control.
Still would also like to see the SGNote with other launchers+cool live wallpaper as I'm no fan of the stock TouchWiz look..it shouldn't be too difficult to make it look cooler than stock right?

Is Note pleasant for night reading?

I've seen many Youtube Note videos with max brightness (some about e-reading), but almost none with the lowest brightness setting.
So, what do you think of reading at night with the Note, with low or no exterior light? Are white letters on black blackground too bright that becomes unconfortable?
What is your experience with apps like screen filter?
Those who come from HTC phones, do you find Note's screen more stressful to your eyes?
I've owned htc and sony phones and the Note's screen is very vibrant and great for night reading. Even on the low brightness in a dark room, you won't have trouble to read unless you have a bad eye sight.
Only people who are used to smaller screens or have pain in the eye will find the night usage painful for their sight. I use it every night before sleeping - no complains so far.
My fear is that Note will be too vibrant and brightfull and will strain my eyes.
For instance, I prefer reading at night with my HD2 than with my Asus Transformer, because it has a lower brightness level.
I don't know about you but I've also own a HD2 and I found the amoled screen very pleasant compare to every htc phones. The brightness can be toggle to suit you. But it's better that you test before in a shop if you are afraid.
There's an app called screen filter on market where you can lower the brightness until the letters are almost invisible. Great for night time reading!

I use it on my HD2, but I've read here that Note's screen doesn't deal well with it and the image becomes greyish

Yep, I find it easy to read at night but only with screen filter. Must have app.
It is pretty bright at night, even with white text on a black background, but no problem if you use Screen Filter or one of the other several similar apps to dim it further. I have toggles on my home screen for several different filter levels for different purposes. Also, I use the night-vision mode that comes with Chainfire3D to turn it to red text on a black background, for even better night time reading.
With Fbreader you can just change the color of the text to something closer to black and have night mode with the lowest brightness setting on. Voila! Very clear and easy to read in pitch dark.
.....
My experience is a little different to others in the thread.
I also come from using an HD2 and to me, reading at night is a weakness for the Note. Even with saturation and contrast adjusted, the pentile display really stands out to me when you're (a) in a dark room and (b) holding the Note quite close to your eyes.
Both these are true when I'm reading. It's not particularly uncomfortable but just a bit annoying.
Could you detail further the 'pentile experience'? You see pixels or 'grain'?
I've had lots of other phones and can with certainty say that I've never had a book reader as good as my beloved Note. Pentile or not.

I can see the separation between the pixels as I tend to hold it quite close on a low brightness when reading. It doesn't make it any more difficult to read, and of course the resolution outweighs that negative, but it just makes it look a little bit less perfect.
I am using Screendim application and it works much better than screen filter. There is Screendim trial just for three days.
Amoled screen cannot be made lower brightness than the default so it must be using contrast features to make it dimmer.
I have to say that reading is the primary reason why I bought the Note. I read a lot of ebooks. I find the Note to be a perfect size for reading at night in bed.
I have never found the brightness an issue... What u need is a good reading app. Thats what makes the difference.
I use Moon Reader Pro and epubeader (free on the Market and can also read .mobi). Both these programs have the ability to change the text color and background and brightness.
I find that black background with pale grey/blue text is the easiest to read while conserving most battery power.
For me, Note is amazing, and if talking about brightness, it can auto-adjust itself.
I agree with documents transformed to pure black backgrounds and maybe 10% black to white text color is perfect for the eye, so you can almost fall asleep while your phone saves battery.
For some reason ScreenFilter worked better on my S2 than it does on the Note. Using ScreenFilter just makes the picture look bad... washed out and difficult to read. I wish my Note could have lower brightness on the lowest setting.
Maybe Samsung doesn't want to go lower to avoid showing imperfections.

I find it better if you use the Voodoo screen tuning app - worth trying

[Q] How is the Display?

Alrite guys, I've planned to get the Z1 by this week and reading every thread here I only got one problem that is the Display, so I want to know how does the display looks like (only for owners of Z1) I want a straight and easy review (don't give any other information on viewing angles other than I asked) how is the display of Z1 head to head and also while watching videos and while playing some motion games does the screen fades out? like in games as real racing 3 we have to tilt display left/right only a bit to turn does the display gets bad or faded? ( I guess no it's a small tilt not some weird angles of using it) and specially is the display head to head great and better than the gs4 or htc one? (head to head only) don't need comment on viewing angles that they fade on huge tilt coz I am not an idiot to use it that way, watsoeva.

I personally like SUPER AMOLED (read samsung devices' display) better, dipper and richer colors (black especially), I hope there will be a gamma adjustment tool for Z1 available soon.

Good
Head on you will get
- Great colors, saturation
- Great at watching movies
- Great reading legibility at direct sunlight
- Great brightness
- Good contrast
Bad
- viewing angles. but you have to tilt more than 45 degrees to really notice the difference. playing real racing 3 is ok, does not distort the display.
- some units get yellow hue. but this is just a software bug, can be fixed by simply downloading an app in google play and adding a little more blue. or wait for a firmware update.
Vs S4 and Vs HTC One
- Z1 has better color, saturation. best at watching movies.
- S4 has better blacks and contrast and viewing angles. but bad brightness, literally can't use under the sunlight. also remember that Amoled deteriorate very fast (1 year, almost 10% loss)
- HTC one has better brightness, better contrast than Z1, best viewing angles.

This was a perfect answer, thanks man! I am not going to use my phone flat in my hand as only stupid people will do that, I just was intended to know if the display is good head-head and while on some games where motion is used (I was pretty sure it will be perfect) thanks again! :good: :good:

Everything you said it's true, but I myself saw a htc one with z1, I guess z1's screen was better with a great contrast and brightness and htc one's viewing angles, no one can win it, though it's just what my eyes saw that z1 had a better screen than any phone atm the moment in market has (head-head or even while gaming/watching vids) cant really say if others see the same

sRGB Mode [Opinions]

So with the new update sRGB mode was enabled and I personally dont find it good, it has too much yellowish tint. I mean how does this make the screen better in any way. The colors might seem accurate but the yellow tint is too hard to ignore. Went back to previous mode. How about you guys
No yellow tint on my display. sRGB seems pretty natural to me, I absolutely prefer it over the standard mode.
Same with 6P of 5X, that's neutral color, your eyes are familiar with vivid-tuned display tone, just like me lol
Your eyes are just used to a brighter more colourful display so it looks worse. it does show of a yellower tint but I'm gonna use it for a while see if I get used to it.
Tbh the mode is for Colourophile's and i'm happy with the normal one
I don't know what you expected. They told you neutral colors when you're used to super saturated colors.
Loving the sRGB personally.
Same, sRBG represent a more natural color spectrum. The "yellow" tint is actually a proper (as close as they could calibrate) representation of true white. Too many oversaturated screens on the market are being accepted as "true" color representation.
Personally I don't like it, too. First I was really excited about it. When i tried it everything doesn't look as shiny as before. All the colors looked like they are washed-out.
Sent from my ONEPLUS A3003 using XDA Labs
I'm not a fan. Personally, I prefer sRGB off and just setting the colour balance slider to max in the display settings. sRGB makes all my icons look washed out, like when you leave a print exposed to sunlight and the ink fades. ????

I use the amoled. So it doesnt matter to me.
Compared to my computer screen, OPO and many other devices the stock colour calibration is closer than sRGB

Something wrong with your screen then. The color calibration is a lot more accurate in sRGB mode, but that doesn't mean you can enjoy the original calibration more since it's more "fun" to look at. sRGB, while more accurate, looks a bit washed out in my eyes but after having used it for a while I don't want to switch back because of how exaggerated and saturated the original calibration is.
Guys you are never statisfied.
You have a choice between two options, stop complaining, choose the one you prefer, and try screen calibration apps like Scrreen Balance, or wait for specific mods/app.
sRGB is close to natural colors all objective tests and done on labs say that, what you like is a different thing, many screens are oversaturated so people are used to that. Thoses complain threads are useless.
Just got my replacement device.
Screen is now perfect and even (had tint problems on the 1st device).
And really loving the sRGB mode instantaneously! NOT too yellow, and finally colors which are not crying" HERE I'M! I'M REEEEED! NOOO, HERE! I'M BLUUUUUUE!"
Great job, Oneplus! Thanks!
People who are complaining here just have no clue and are just conditioned by the companies into loving overblown colors. (Just like many people love too loud and too bass-heavy music because the music industry has conditioned them into that.)
Its a similar thing on the S7E, which in 'basic' (sRGB) mode has been measured as the most accurate phone screen available. Once you get used to the more natural look its difficult to go back to 'shop mode'.
Try it for a few days. You can always switch back
As an added bonus you may also have slightly better battery life.
Its making the decision to keep the phone as a second driver easier and it will replace the p9000.
Compared with s6 on basic mode and op3 does a better job, couldn't do a good job in clicking pics tho, you can barely make out anything in these
I really love the sRGB mode. Finally the colors aren't so super shiny anymore. Coming from an iPhone and never liking Samsung like colours that's a really big deal for me.
When white is not white, then it sucks. Better give us KCAL control,
Let me decide which contrast, hue and tone i want =b
So, i agree, sRGB sucks

Absolutely agree with you, when white is not white it sucks, other colors do appear more natural, this mode is best for viewing photos and videos rest I'm not sure .
We need custom kernels with kcal, waiting to try out cm but dash ????
They should call it sDRAB it makes my screen look like a corpse. I like a little spice. sRGB is way too bland albeit accurate. I guess it's useful when using photoshop or snapseed but I don't see any day to day application for it. Other than dying of boredom...

Contrast (true blacks)

How well do you know your fifty shades of grey? Rate this thread to express how good the Lenovo P2's display contrast is. A higher rating indicates that black is true black, rather than a very dark gray.
Then, drop a comment if you have anything to add!
The super amoled screen is excellent in this domain.
It is an AMOLED display. What do you expect? Black is pure no light. The screen is switched off a the dark areas. It is excellent for inverted text reading (grey text on a black screen) with very low power consumtion..
I cant really distinguish the bezels and dark background of soft nav keys.wow
i use sustratum with swift black theme....
it is PERFECT.... awesome too see each app with black theme.
i comparedside by side the black of other phones of my friends and everyone now noticed HOW MUCH COOL is to have an amoled display eheheheh ( my first amoled phone and i am on love , i won't turn back to ips)

This phone display is great but again there is super amoled display on my friends Samsung C5000 and it is even awesome .It has even better sharpness and shine of colors on it. (Although our display is also a super amloed)
Sooo , I was thinking if we can get Kcal color settings or something it would be fantastic.
i modded my display. now my white is perfect, just usa a custom rom with live display and i put green value from 100 to 92 . now whites are good

Yeah will try when in 3 days my bootloader is unlocked.my white colour is currently yellowish at normal settings in stock s244
The screen is unbelievable for the price point . But the pure Red gets blown away though , eg., see the youtube app logo
I set my green value to 96, now it's perfect!!
Pitch black for sustratum is the best.U save a of energy as well and it looks awesome.
