Look very great on the xperia P, could you provide a download link to the wallpaper?

Things look FAR better on the Xperia P. I tried to not bias myself in as many shots as possible by not identifying which phone it was before deciding which was better, and in every single one I found the Xperia to be the superior display.
I do hope they're able to either overcome the size limitation of the white magic displays for LCDs, or at least continue this work on future OLED displays.

Wow. the quality of the xperia p display is unreal. Wish the xperia s came with white magic as well

I have neither phone and stumbled onto this thread by accident so no ax to grind but there are some problems with comparisons of this sort in general and I have trouble accepting the statement as to bias quoted here.
As to the bias: it is impossible for me to not immediately know which phone display I'm looking at simply because the size difference of the image is painfully apparent in each and every instance with that of the Note being significantly larger. Even someone such as my self who "has no ax" can't avoid bias it's built into the human animal and can't be removed except by carefully designed double blind trials where there can be no hint of identity. No one could claim the conditions of the samples here are "double blind" in fact there is zero level of disguising which is which, ergo bias is an unavoidable consequence.
Regarding the comparison itself:No information is given regarding the displayed images. The resolution the original images were shot at is just one example of possible problems with the comparison. If the originals were shot at any other than the native resolution of the particular device in question it could appear distorted when scaled to the non-native display parameters. For example, if it were shot at qHD then blown to HD it would certainly suffer in the translation because the larger display simply can't offer more information than was contained in the original and might simply make any flaws larger and thus more apparent. A multitude of other artifacts could be introduced depending on conditions and even on the display of the screen of the device you are looking at the thread with.
In the image of the Headphones the words on the earpiece are very much clearer on the larger image on my computer screen ditto with the netting in the fruit image. On the other hand the colors and white balance appears to be better on my screen on the smaller images.
Is one better than the other? Very subjective.

Of course it's subjective. That's why we have some people out there who prefer to look of OLED displays to LCD, and vice versa. As for the comparison, yeah there are some pics where the size gives it away, but IIRC there were a couple where the sizes were similar. The pics aren't all loading properly for me now for some reason so I can't identify which one those are, but before making my post I did view the pics on both my tablet, 40" LCD TV and 55" LCD TV and in all cases I prefer the Xperia Ps screen.

Screen color temps between units

Here's a side-by-side of two ATT GS2s on auto brightness showing the same application. The one on the left has a bluish/greenish tinge to the display, while the one on the right looks...I dunno...pinkish? Almost dirty by comparison, at least to my eyes, as it's much harder to read in low light settings. I thought at first it was the Helvetica vs stock font, but it's clearly the panel's lighting characteristics.

Here are the same phones again running the 'dead pixel test' from the Market, set to max brightness on the white screen color test.
The one on the right doesn't seem to be able to produce a true white.
Now, I get that there are different screen suppliers, and manufacturing variances among panel batches, but this whole thing has me a little disappointed at Samsung's QC. I would love to know what qualifies as a successful screen test, because the one on the right is a huge disappointment to my eyes. Just for the hell of it I compared both screens to my old Captivate, and to my surprise that had the most accurate color reproduction of the three.
How bout you guys - true whites on your screen? (try the gmail app, for example) Maybe I just got a bad batch?
The screen on my SGS2 has no colot tinge whatsoever. It's white and bright. I did however notice a bluish tint on my Infuse; which drove me crazy. I actually exchanged 3 Infuses because of a flaw in market where I got the "unable to download, insufficient memory on device". Each Infuse had a different tint, or brightness to the display. I switched to thw SGS2 and haven't looked back since.

Wow... big difference.... what the hell...
I thought this too about my SGSII when comparing it side-by-side with store units... Turned out for me the brightness was the same but another setting (adjust screen to save battery or something like that) was checked on my phone, making the screen look like crap on some colors, including making white look gray and yellow look bluish. Once I uchecked that box the display looked fine.
yeah I am anal about colors too. Being a photographer.
So I was looking for ways to improve the displays on my SGS2(now returned).
I have a Gretag i1-Pro spectrophotometer that I use for calibration and also matching color swatches. So I 'calibrated' my screen to the best of the available software. There is a program call 'Screen Adjuster' you guys can use to alter the RGB values. However gama will be off, and you can only calibrate EITHER high bias RGB or low bias RGB. There is no way to calibrate both.
Have you tried Supercurio screen tune? He just started making it but can probably help you out with colors and such.

QC and screen temperature were both big issues with the ISGS2 when it launched. There's a 100 page thread that's been talking about it since May. Five ISGS2's side-by-side all had from slight to wild differences in color temperature. Some of the ROMs also alter color temperature which makes it even more confusing. Cool/blue is what's intended to be normal and warm/yellow is the exception. The phone on the right in the pic looks like it has a warmer screen. I'd guess they changed either the screen or manufacturing process for the ASGS2 or you guys would have been freaking out by now.
P.S. - Samsung manufactures all their own displays and they all come from the same factories. So if there are differences it's QC or allowable deviation.

[Q] Black Fragmentation color on display - is it just mine?

So I am seeing some color issues with my SII
Not sure if it's just the way it is (because I am coming from the LG G2x which had the most amazing display you can ever imagine), or is it just my phone.
The funny thing is that even though I am attaching a screnshot, obviously YOU will not be able to see the issue (since of course, the pic itself is fine, and it is the display that makes it wavey...)
I am not even sure I am explaining myself the right way.
Wavy colorts, uneaven, almost cartoonish-like, smeary.
It is most apparent with darker shades
(U can't see it here)

Samsung's Super AMOLED Plus displays exaggerate colors and shades, and that is it's key feature. Not sure about your phone, but if you think something's wrong with your phone, go check with your service provider.

Thank you!!!
Found some info here, i wonder if mine is one of these....

I hope more members will have something to say, perhaps they have experienced this as well.
I was also thinking whether this can (hopefully) be a kernel issue or color calibration issue? I know that some kernels has effect on the colors, but I am out of my field here and completely wrong
The weird thing is that light colors are perfect. When GRAY or BLACK, it just looks bad.

I've got something similar to that.
It's not noticeable in a well lit environment but if I'm in a dark room and have a black screen on my sgs2, some blotches seem darker than the rest of the screen.
I wouldn't be too bothered about this if it was just one or two but there's one large one and a bunch of smaller ones scattered around the screen.
Thanks!
I wish I could upload a photo to show it, but (funny enough), my only camera is my phone's camera (a single student - what r u gonna do?!)
This is especially noticeable when I take a picture or when I use the Music app (pictured above), where there is huge smears of color going from the dark to the lighter.
I hate to even imagine it, but I think I will have to depart from my SII if this is something that isn't fixable. If no one else experience this, I will get a new SII
(i don't know anyone that has the SII so I have no one to compare it to)
Managed to take some pics
Hope U can see it:
Look at the bottom discoloration:
All menus with shades of grey and black present this issue (kernel problem maybe?)

Lumia 800 screen looks "serrated". Is it normal?

So I just bought a new Lumia 800. My previous phone HTC Mozart so I compare their screens and there is one thing that annoys me: while my HTC Mozart displays everything from fonts to live tiles smoothly, those in my Lumia 800 look "serrated":

}
in which the "No sim" one was taken from my Lumia screen. Similarly, when white texts are displayed in black background, they look serrated too which a little bit hurts my eyes.
Could you tell me if this is normal for AMOLED screens or is it just my device's problem?
Thank you in advance.
I believe this has to do with the Pentile Matrix of the Lumia 800.
search "pentile" on this forum for more info.
found an online artice http://www.theverge.com/2012/1/11/2699574/lumia-900-amoled-display-no-pentile
talks about Lumia 900 not having this type of matrix
Yep, what (s)he said. It's due to the PenTile matrix used.
Thanks for all the replies. Now I believe my phone's screen is normal, although I don't really like that pentile effect at all
Not many people do. Some people apparently can't see the effect at all. Annoyingly, I can.
I can see it if I look for it, but it doesn't bother me in normal use.
Unfortunately, I got used to the smoothness of HTC Mozart display, so this really annoys me
i find it's far more noticeable if you use more warm colours (like oranges and reds) than if you use blues or greens.
I am used to the pentile. I have always disliked pentile screens but now after using one for two weeks I can say the pentile doesn't bother me one bit. Even though I see it all the time as I'm sensitive to these things. The true black and good response time of the screen makes up for it. I now prefer it over the sharper screen of my old Xperia Play. Much more comfortable screen to look at on the Lumia.
Like comparing LCD to plasma. Amoled seems much easier on the eyes than ordinary LCD.
I can notice it and I hate it, but I knew what I was getting. The Samoled+ on my old GS2 looked much better. Honestly, even looking at my GF's 710 I have to say that I like that screen better for some aspects: pics and vids have more natural colours and look less pixelated, text is also more readable in the browser without zooming. Anyway at the end of the day the 800 is overall a much better phone, and its unique design mekes you feel like you're holding a true work of art in your hand. Right now thinking about going back to my super plasticky GS2 makes me cringe.

Screen brightness

Just walked into a corporate store to check this thing out and get a feel for it, see if its worth leaving a GS III. Everything about it seems legit, except the screen set to full brightness still seemed too dim. Might just be the AMOLED screens spoiling my eyes for the last 2 years, but just wanted some comments from owners who have been able to take this thing outside.
So how is the brightness for you guys? Is it still fairly viewable in sunlight? Please no discussions about color clarity/saturation. I know it doesn't hold a candle to reproducing vibrant colors like OLED does.
I went out in full daylight and could see perfectly clear. First time ever on a smartphone that I've never had to cup my hands around the screen to see
Sent from my Droid DNA. 1080p never looked so sweet
Awesome. I was initially concerned with it being LCD, but I remember reading on a few sites that the superiority in SLCD3 was its manufacturing quality and clarity. I guess that coupled with the display being bonded better and closer to the surface translates into better visibility. Thanks for responding.
It is interesting to hear others review on this screen.
Since the major reason I did not buy galaxy 3 or note is AMOLED screen really looks dime even max brightess is only equel to my htc one x 's 50% brightness level which I can not accept.
It's a beautiful sunny day in Los Angeles.
Walked outside.
Had no issue seeing the screen contents.

We decided to pit the Droid DNA against the iPhone 5, Nexus 4, HTC One X, and Samsung Galaxy S III (from left to right it's the iPhone, Nexus 4, Droid DNA, One X, and Galaxy S III). All screens were turned up to maximum brightness, as can be seen in the photo above. The first thing you'll note is that the Droid DNA isn't the brightest by a long shot; that title still belongs to the iPhone 5, followed by the One X (though the One X seems brighter because there are simply more pixels in total). Disappointing? Yes, though it's still plenty bright enough to be visible in daylight.

The displays on the One X+ and 8X are 20% dimmer than the OG One X too. Previous One X's had panels from Sony, Acer, and Sharp. The new display on the One X+ is from a mysterious fourth vendor (0x944a03) that hasn't been identified yet. Maybe HTC's changed panel vendor's for their new devices?

Alldocube iPlay 50 Tablet (Android 12): Display output has greenish tint + artificial sharpening artifacts – How to fix?

Note that the described tinting effect is IMO, and based on my eagle eye and 30+ years experience in the field neither caused by the color of the backlight LEDs (as one would immediately think from seeing the snapshots; I know backlight color variations ... this clearly isn’t one), nor as someone presumed, the panel lamination glue.
Question to Android developers who are familiar with Display Color Profiles/CLUTs and output filters (if such exist):
Already owning an Alldocube kPad and iPlay 20s, which I'm highly satisfied with, I recently purchased 8 pcs. of Alldocube’s new iPlay 50 via AliExpress (excellent deal: each 2 pcs. for a total of USD 225 delivered). The hardware built quality is as with the previous models excellent, but the display on the iPlay 50 has a major problem:
When placing the iPlay 50 next to the excellent kPad and iPlay 20s one notices that
the colors are completely off and have a greenish tint
an artificial contrast enhancement/image sharpening effect is obviously applied, which adds an annoying and disturbing halo effect to detailed areas and edges where dark colors adjoins lighter color (e.g. black against medium grey).
Both effects are globally, so not limited to a specific app or screen area.
Unfortunately the effect is very difficult to capture in photos, attached below are my best efforts (the chinese comments are meant for Alldocube’s Customer Support, which isn't very supportive on this issue, although it would be in their best interest).
In my opinion it is not a hardware (LCD panel), but rather a software issue, thus should be easily fixable by their software engineers. Note that it is NOT POSSIBLE to correct these problems through Android’s Settings > Display > Contrast & Colors! The greenish tint remains, and so do the artifacts of the unwanted, unnecessary sharpening. Greenish tint also isn’t affected by Material You.
Any suggestions or ideas how to fix this? Because if I can’t fix it, I'll have to return those tablets, which would be real pity, as the tablet as such with its laminated 2.000*1.200px 10.4" IPS panel is an excellent bargain.

hello
i bought brand new one and its like yours i think that the lcd pannel are just bad quality
I have never seen a screen as bad as iPlay 50. I think it would be better if rooted to adjust the sharpness.
i forwarded this post to the seller, hopefully we get some update on it soon cuz i also experience this issue
