Netflix looks like crap

It's only me, or Netflix looks like crap on WP7? I just got the phone yesterday and one of the things that push me to get the phone was the ability to have Netflix... but after several movies,, I saw that the quality is very bad, it's like is not using the full Color scale. The movies look like is using a 16M color pallete... is that the way its looks? I tried over wifi and 3g and it was the same

I've noticed the first couple of minutes are pixelated, but then it smooths out and runs fine. I haven't noticed any color problems with it. What device are you using it on?

Yeah, this is my experience as well. Something to keep in mind is that the Samsung AMOLED phones (Omnia 7 and Focus) have some color banding, so if whatever you're watching has a lot of gradients, then it may look worse than it would on other devices. In my experience with my Focus, I haven't had too many problems with the colors looking bad.

I use the Surround and have been satisfied 100%. Occasionally it gets pixelated due to bandwidth but never any color issues.

I havent been color problems in Netflix. Looks good on the screen resolution.

I have the Samsung Focus.
I'm not talking about been pixelated, resolution wise it's looks good,, the issue is with the coloring . is like netflix is using a less than a 16bit color pallete,, take you computer screen for example, go to the properties and change your color to 16bit or less and you'll see what I'm taking about... is the gradients

I guessing its a super amoled problem then as others haven't had this.

I found this article,, it confirms what I was trying to explain... and I though I was getting a better display going with samsung instead of HTC..., but I think part of the issue is due to WP7 , I used to have a Galaxy S and never notice the color banding issue.
http://www.mobiletechworld.com/2010/12/05/super-amoled-color-banding-issue-microsoft-could-partially-fix-it/

Let me assure you that the Galaxy S also has horrible color banding. Well, the ones I've used do as well. All AMOLED screens do, to some extent. Gradients end up looking reeeaaally bad, which is why I'm sticking with LCD until the technology improves.
Sorry bud, it's not Netflix's fault. Blame Samsung. Hopefully it can be fixed with a software update.

The galaxy s phones that you've used have all been duds then because its definitely not a problem with amoled in general. The pentile "pixel" arrangement may make them look a little less sharp, but there is no color banding on android.
That definitely looks like a wp7 software issue as the article says.

lol you guys must be on crack i have a focus and i see no issues while watching netflix. the beginning is pixelated for the first 30 secs or so and then the image is perfect hd quality. theres no comparing the image quality on this phone to one of an lcd.

well, if it's only on the amoled displays, sounds like a samsung problem. Have you tried to exchange it and see if its better?
And how would you notice it on a galaxy s phone? Android doesn't have netflix.

Funny, because I'm typing this from an Android phone with an Amoled display and if I view an image - video or still - that has color gradients I get the same color banding as shown in that article.
Believe me, it's an AMOLED thing, and can be fixed if programs run in 24 bit. Most don't, though, which is why LCD displays are better in my view

wanted to chime in that netflix looks pretty awesome w/ 3g on my LG Quantum

Yeah,, I guess is not a Netflix issue,,, but using netflix was when I first notice the issue because netflix use 16bit... is a combination of WP7 and Amoled, WP7 could have reduce the banding issue by using dithering but they did not... When I had my Galaxy S running Android I never noticed that issue and I had the phone for 6 months... even my wife's iPhone3gs looks better on netflix..., I guess I will have to get used to it... since of all other WP7 phones on At&t the Focus has the better Camera.

LG I want my yellow back

So, I love everything about this G Pro except one thing it was bought for. The display of it is a disaster. I mean it's the worst LG smartphones' display in some years. I prefer to use indoors @ 60% brightness with autobrightness on and in this setting everything looks so dim, grey and almost unseen-able. Especially yellows, I mean there's almost no yellow colors @ all even at 100% brightness, but at 60% it's even worse. And to not be a windbag I've snapped some comparison photos of G Pro next to another LG smartphone, which has, IMO, the best screen ever. When you hold them both in hands its no question which one you'll keep to yourself being forced to choose
So if LG will continue to mistakenly set their display's color temperature to 10000K, I confess my next phone would be HTC or even Motorola. I don't want to see ppl faces of corpse skin colors, and green everywhere where yellow supposed to be

Your comparison phone is over-saturated and blown out. I am looking at the images on an very expensive and calibrated IPS at work. Neither phone has it right, but the G Pro is closer in comparison. The G Pro certainly is cooler in color causing the yellow to become green-ish. But comparing an almost green image looking for yellow is silly. It won't make people look like corpses... you can test that too, with pictures of people... odd you didn't include that in your image set.
Edit:
Wait, hold the phone, there is one person in your test, and they don't like like a corpse... imagine that.
Edit 2:
Wow, if you really can't see that the G Pro looks better, you need to have your eyes checked.
Can you really not see how **** the other devices screen looks?
What ever you used to take the pictures is very grainy too... just fyi.

You don't see my point or don't want to. Look on your expensive IPS at this image http://www.google.com/search?site=imghp&tbm=isch&q=5403393757_b5b17ea28d_o.jpg You see? There's tons of colors in it. Then transfer it to your G Pro and open, it made all color turned into shades of blue. It's intolerable. Well, Nitro also make this image bluish, sort of, but in way no as blue as G Pro
Nitro has its fallacies, of course, it can't show every possible color in the Universe, as I remember it covers 87% or 97% of sRGB when G Pro covers 99% sRGB. But Nitro has col.temp set around 6800K and all images looks true to life. I haven's seen one person who was dissatisfied with that screen, even photographers. And G Pro has around 9000K, it's way too much, the white percepted as grey, yellow almost gone and turned green, oranges turn into cherries and etc

No, even there it has slight green tint, and white below is blueish, you must have good IPS monitor or mobile display at hand to compare. When you compare the difference is stunning and eye-popping.
Also, in original post the second picture is https://play.google.com/store/apps/details?id=com.gombosdev.displaytester showing yellow on both devices and in archive all other main colors like white, red, blue. My concern is yellow and white because the white is what you looking at most of the time

No, I don't think so. Every other youtube review unit had the same cucumber-blueish tint on white background, EVERY. So it's LGs settings that are faulty.
Do you have any spare phone at hand? Like HTC One? It almost perfectly calibrated. Go to some place, put the same white or yellow wallpapers on both devices and compare which unit will be more eyepleasing and easier to look at. I'm sure the other phone than G Pro will be
We're waiting for anandtech review, pity that he doesn't even look at G Pro, it even prefer noname Oppo Find5, it means bad for LG, it's bad marketing that even anandtech doesn't review their phones

I have yet to find a single review that had anything negative to say about the display on the Pro. The worst comment is that it's almost as good as S4/One. I even saw the color accuracy praised in a review. I don't doubt there are likely exceptions, but not in the ~10 reviews I browsed through.
My co-worker has an HTC One and while due to size his screen looks crisper, the Pro looks damn good otherwise.

Checked out that link, everything looked perfectly like they saidit was supposed to even at lower brightnesses...maybe u just have a bad screen, i watcj lots of vids and pix on mine and they all look fine

"The screen is very nice." First sentence in what you quoted. Not a single one of the reviews mentioned an issue with the color balance. I personally do not see an issue with the color balance. A number of other people in this thread don't see an issue with the color balance. I definitely saw an issue between the two in the picture, but my phone doesn't look like that and from the sounds of it.. neither do most of the other people's. So, if everyone else is telling you it's your phone...

Why are you so effing worked up over this? It's not nearly how you describe. Almost everything you have pointed out is either slanted/strategically chosen quotes from actually solid reviews or pure hyperbole.
Just sell the flippin thing and move on, your exaggerated criticisms are going to scare off developers that we desperately need.

Will Google tighten up quality control on the Pixel 2 XL?

Do you think Google is going to subtle improving quality control on the Pixel 2's, specifically the 2 XL?
I have a 2 XL that I received on the 20th. Overall the phone is great, but I do have the off axis color shift. I see some that barely show a color shift and others that show a more pronounced shift. I'm debating sending the unit back and waiting a couple of months before checking it out again.
Do you think phones in a couple of months will have less off axis color shift?
Thanks,
Rick

The color shift is the polarizing lens applied to the scree. Other phones do it too.

Google says this color shift is inherent in the P-OLED implementation. They might try to lessen the effect with a software update but it's a feature that probably won't go away.

It doesn't even bother me... I think half the sky is falling reports, are coming from Apple fans trying to do damage control because iPhone 8 sales were lackluster...

I think you know the answer to your question: NO ONE KNOWS

There are multiple levels of color shift. Some are ok and some are horrible, such as mine phone. Hence the QC question. Alot of these phones are abnormal, so saying it's normal is not legit, alot of fluctuating between phones

The question is if someone has returned their phone with excessive blue shift and got a new one that's acceptable. I wonder if there really is a large difference between phones or is it just based upon individual perception, or what

The simple fix is that if you are trying to write an email or watch a movie at a 45 degree angle from the screen... Tilt the screen towards you. Problem solved!

My phone is awesome in all regards.
Samsung best remember googles android( Samsung has been trolling Google) put them on the top of the smartphone business.
Along with over-saturated screens and the android play store.
Now im seeing articles online about a Pixel XL 2 recall seriously,its not that bad.
I have a slight bluish tint but not enough to return this wonderful device.
Im really wondering what is the endgame here,does google keep lg as a screen partner? Highly unlikely at this point to many headaches.
This really is the best smartphone i have ever used until the Pixel XL 3 is released lol.

Here's a couple more at various settings. Still looks nothing like the video.

I've read on a few sites that the blue shift is from the circular polarization filter over the OLED screen. I would GLADLY give up the circular polarization filter to have a PURE WHITE SCREEN AT ALL ANGLES.
My Nexus 5X the screen would be black in portrait while wearing my polarized prescription glasses. It was no big deal to see the screen though.
1. Lift my sunglasses
- OR -
2. Turn the phone to landscape
Designers dwell on small problems only to create larger ones. What they should do is not apply the filter layer to the screen, but add it to a glass screen protector. They could sell "clear" or a "depolarized" version
Then everyone's happy.

I find it really hard to gauge where my screen falls in the blueness scale when comparing to pictures people have posted online and in threads.
I wish there was any easier way to tell.

How prevalent is black crush?

This is one issue that actually affects my user experience. I'm trying to decide between an RMA and switching to a Pixel 2. If black crush is a universal problem, I'll go with the latter but if it only affects a few devices I'd rather RMA and stick with the P2XL. Chime in, black crush/screen bleed - do you have it?

I have it. Very noticeable. Curious if it is widespread or not, as well.

When is it noticeable??

FYI - the Pixel 2 has it as well.

I seem to be finding mixed messages on this. Some report this is not an issue on the Pixel 2 and only the XL. I only have an n of 1 for each device - my P2XL has it, my wife's P2 does not. Ultimately, this is what I am trying to figure out - how widespread is the issue, do I play the lottery or exchange for something new or just keep my original XL, though I'd certainly miss the camera and active edge.

Low brightness, dark videos and images, basically any near black colors get "crushed" to black. I was watching The Croods on a flight the other day and there is a dark scene near the end of the movie where I couldn't make out what was going on because it was so bad. Any dark area of the screen went completely black and/or black and very pixelated. There are a few test images in a thread on Reddit to see if you have it, I'll see if I can link it.

See I don't think it is necessarily the screen as the display has a really high range of greys, so I think it could be fixed to some extent. The bigger problem I have is the ridiculous amount of black smear at low brightness. I never had anything like that on my Nexus 6P, it is dreadful.

Yeah same. I've got a decent unit at normal day usage. Once it gets to lower brightness and night mode is not very nice. The black crush is slot worse with night mode
.but black smear is there with or without.
Wish Google just went with a Samsung panel

Yeah, this is kind of a weird one as it seems to affect both P2s and P2XLs, but not all. Maybe its mostly a software issue but is most pronounced on certain screens for some reason? Idk.

It is difficult. Also do you trade in for another one? But run the risk of getting worse blue tint or grain or uneven whites... I'm going to give it a week, see if I find it a big deal or not. 90 percent of the time I don't notice because the brightness is higher during the day

Wow, so I've got a pretty bad unit...
Black Smear: Even on full brightness and slow scrolling. So bad, it even covers Text to the unreadable (It's complete gone and "hidden" under the Black-layer).
Black Crush: Until 40% noticable on Photos. Mostly in Shadows which are normally grey. They turn to a complete Black which looks awful.
Blue tilt: Starting at a very small angle. Pretty extreme and bad, but the other two are more of a dealbreaker for me.
Currently requesting an RMA after resetting my Device. And be sure to be nice to the Support. They did not manufacturer this Device wahtsoever.

I don't see anything wrong with blacks or greys during videos or on pictures whether night mode is on or off or brightness is high or low. Can someone post a screenshot or two? I'm curious.

I'm debating if I should exchange it or just keep it, it's only noticeable at leow brightness

I have the same effect in original Youtube app. It is just a bad background gradient in the application. Don´t blame the phone....
When I open Messenger with black background and grey status bar at the top of the app in the same brightness level, there is no greenish effect.

I am also having uniformity issues. Very noticeable, unfortunately. As there are no 512GB Ultras available anyway ATM, O will just have to live with it for the moment. Maybe I get used to it...

mm weird, I see it in every single app with dark grey background, even in settings (w/Dark mode on), the bleeding is a lot bigger from the top right corner.
EDIT: Just checked the messenger app (FB messenger) and background is completely black so most pixels are off except for the letters and gray search bar but bleeding wouldn't be noticeable.

I've just checked it with Gmail since it is also a Google application and you can notice the bleed when the lights in the room are turned on and I try to cover the top of the phone to see it. After turning the lights off, whole app is equally gray so in my opinion it is just an optical illusion. If I recall well the AMOLED displays use some kind of dimming (tinkering with the frequency) in order to reach a lower point of the brightness that is not noticeable for human eye. Probably this can be seen when covering a gray part of Google apps in a room that has another not so bright light source.

I made a picture. It is showing a 5% gray test pic and supposed to be uniform. It is easy to see and I was kind of shocked when instantly noticing it the first time I was using it in the dark. Settings and many parts of the dark one UI are using grays in that range.
Anybody else? If it is rare, it will be worth pushing for an exchange.

I did the same test, I'm attaching a picture of my Note 10+ and the S20 Ultra side by side. Uniformity seems a lot better on the note 10+, however on white background the Note 10+ turns more red when I slightly tilt it while the S20 Ultra seems to shift colors a lot less and still white overall.
Still not sure if it's worth the hassle to return.

Ok, the fact, that it looks very much like mine can be good and bad ?
Could you please check, if is different at 60Hz? For me, it is clearly different.

Oh wow, you're right! I set it to 60 hz and QHD+ and uniformity on the gray test got noticeable better, still some green on top right corner and around the punch hole but noticeable less. I love reaaally 120 hz during normal use though.

Thanks for confirming, same here. I wonder, if this is something, that can be fixed in software... And if the rumoured 'dynamic refresh raze' update might change things.
Could please note people check their Ultras displays?

Same here with my s20 more visible at 12hz refresh rate with dark theme

Damn it, ok, then I really hope that it is fixable... Weird.
I am using smiled displays since Symbian Nokias, never had one, where I noticed it so much.

I remember all the Mate 20 Pros with LG screen had this issue buy way worse in some cases

In some cases they were normal during the first days but the problem evolved until the display was unsusable in low light conditions, hope the same won't happen to our phone during the next weeks.

yeah I don`t have this issue I did the screen test in Gmail and download the app that does all the different colors including gray, at the lowest brightness and at other levels of brightness at 120hz its all uniform.

Mine is most noticeable at around 35-40% brightness and with 120 hz but still noticeable with 60 hz while on the note 10+ I can't see any green at all at any level of brightness. I think it's a quality issue and variation of OLED screens but not sure if it would count as "defective". Samsung doesn't do exchanges so it would be a pain to return everything and recorder without the promotions and reservation/pre-order credits. Ugh not sure what to do yet.
EDIT: Btw I tested with gmail and didn't notice the green in the app since it's light gray but as soon as I drop down the notification panel (w/dark mode on) the green is immediately noticeable. It's only with very dark gray that lookd almost black which is what Samsung use for all their apps (settings, calculator, messages, etc.) when dark mode is on. I wish they used true black so pixels were completely off like with facebook messenger.

I am also unsure what to do. I have to say, however, that this is the device that gives me the most uncertainty ever. For this opportunity price I want a good to perfect display. @vwite Don't you think that the dark grays are too bright as well? It wouldn't be so visible otherwhise. I also sent my picture to the 'write the CEO' address and a pledge to be aware of the issue:
https://www.samsung.com/uk/info/contactus/email-the-ceo/ (example: UK)
I will try checking in a store, which will be totally hard because of the light there. Maybe I will just order another one... Or a plus ?

Made another picture 'for the CEO' :silly: and will also attach the source image I showed on screen. To replicate:
- 25% brightness
- Show 5% picture in a dark room
- made picture with an S10+ on full auto

Thanks! Please let me know what they say.

Actually I ordered an S20+ now and will most likely just give the Ultra back in the first 2 weeks. Yes, it is a pain, but I really can not stand the screen as is. I am even putting it in its box before I have the plus and using my S10+ in the meantime - the green tint is driving me a little nuts.
I am having a hard time justifying the thickness and weight for a feature I hardly use (amazing zoom) while having an inferior main camera at the same time (focus issues).

i noticed this issue too on my 20+
it seems to be worse some days less bad other days
it also is very dependable on how much ambient light is around - eg is much more noticeable in dark rooms
and yes is an issue with Samsung dark mode that isn't true black but some dark greyish
other then this - all other colours look amazing = so not sure if the screen itself is defective
I do hope there will be a software update that will fix this or make it less visible
