Thumbs down Horrible blue aliasing/artifacts in black areas during video playback

Tonight I started watching a video on my phone and noticed some terrible blue boxes/artifacts/aliasing during playback. The video in question is a 720p mp4. I played it on my dinc and the same blue boxes/aliasing is NOT present. I do see a very, very minor aliasing happening which is just characteristic of a lossy video encoder. But the blueness is not there on the dinc.

It's hard for me to describe properly, but I might be able to find a video on youtube or publicly available video I can post a URL to so people can see if it happens for them.

I thought perhaps it was the video player I'm using on the nexus (mx player), but I tried moboplayer (which I use on the dinc) and it crashes on the nexus. I guess I can try some other video player on both the dinc and the nexus to compare, but I'm pretty sure this is a problem with the nexus.

I watch a ton of video on my phone, and this is a huge deal breaker for me. I'm willing to put up with the less than stellar signal and other issues, but this is just horrible.

I'll reply as soon as I find a video people can try out to demonstrate the issue. Has anyone else noticed this?!

Ok, I found a clip that exhibits this. It shows in the default movie player on the nexus and also the mx player app.

http://dl.dropbox.com/u/28717002/test.m4v

Can someone out there play this back and see if you notice it? I think it's pretty hard to miss, but would like some others' feedback. Watch the black parts of the video (especially the guy's hair on the left) and you'll see some really annoying blueish/light-blue blockiness in the black areas. This same video played back on my dinc doesn't show this.

I'm also curious if people with a Rezound can check this? That will probably be my next option if I return the Nexus.

Thanks in advance.

I can also see it. As soon as I got the phone I wanted to see the HD screen in action so I watched the Transformers trailer and The new Harry Potter trailer in HD(on youtube) and I saw that when there was dark scenes the blacks were pretty washed out. Kinda like what you see on some LED tvs. For myself, I don't watch too many vids so it's not a deal breaker for me. But I can see where that might bother others.

Yup, i noticed it the first day i had the phone. The screen is honestly worse than my old HTC Touchpro 2 with respect to clarity on everyday views.

could you post a picture of what type of artifacts you're seeing? I dl'ed the vid and put my brightness up and i'm noticing maybe very very slight noise on the blacks, which to me just looks like something similar to high iso on a slr camera type noise. it is very very feint though and i can't really notice it.

i'm sure we all have different levels of what we consider great quality, but maybe it is a batch issue in production? because i'm quite happy with the display.

Apply the "Microbes" from live wall paper and tap around the screen (not long press) and you will get the worst bleed thru artifacts. Its unreal, you can almost make the screen white.

hmmmmm...

"Nexus S" Microbes - Live Wallpaper - YouTube

Microbes live wallpaper from Nexus S - YouTube

do these videos exhibit the same artifacts you guys are trying to describe? to me, the white cloudiness is intentional as part of the design of the live wallpaper.

This is what I see, as well. For the most part the blacks are very deep and everything is gorgeous. There is a slight bit of noise (that's what I'd call it, also) on his hair, but nothing that I would notice without looking for it.

Honestly, you might have a defective device. The blacks are deep on mine, even with full brightness. Extremely little artifact in areas that aren't true black.

But in the heavy shadow areas, it's as black as the bezel.

I wish you hadn't pointed this out but I see it as well. I noticed it watching the HD Ghost Rider 2 trailer on YouTube. It's strange though because on the app selection screen you can plainly see the display is capable of pure black so why don't videos show that? Maybe a software update can fix it?

Or this may just be the pentile screen norm.

I know when the SGSII came out, there was talk that the video player would support Samsung's mobile DNIe which would allow selection of things like dynamic, natural, movie modes, etc. I guess the GN has no such settings? Perhaps it's the saturation settings for the display that is causing this.

I have a rezound and just tested the video as this is a very important factor for me as well. I can tell you that there is NO artifacting, blockiness, blueish anything. The video plays perfectly, just like you're watching on TV.

The problem you're talking about absolutely has to do with the pentile display. I played it on my old droid 3, which is also pentile (but not super amoled) and it looked horrible. But I knew it would. All my videos, HD or otherwise, had problems with dark scenes on my d3. This is especially noticeable when the black isn't true black but a lighter shade of it that constantly changes due to slight changes in lighting (within the scene itself). It made certain movies just plain unwatchable on my d3. I never had this problem on my first android phone (DX) or on the rezound. Also makes me think your Inc is of the SLCD variety, which the later ones came with and is the same screen tech in the rezound.

I thought that the denser pixel count of the HD screen on the Gnex would make it less obvious, and maybe it does. But from the sound of it, it doesn't seem enough for those that watch a lot of HD content on their phones like me.

Thank you for pointing this out. If I had any lingering doubts about sticking with my rezound, you just ended them. I'm on the go all the time so do most of my video watching from my phone. My HD rips look stunning. I've seen no distortions in any on the videos I watch.

To the poster, since your dropbox link streams, just go to a verizon store and install mx player on their display rezound (if you can't access the market, you can always download the app directly from the dev's google site, Download - MX Video Player, using the browser). Then side load it and play it on the rezound. I guarantee you will not see a single artifact.

Thanks again for the info.

Looks like you are right. I had thought the screen of the Nexus was the same as the Galaxy S II; but it's actually a high-def Super AMOLED vs Galaxy S II's Super AMOLED PLUS.

Samsung Galaxy Nexus Phone Review | PCWorld

Quote:
The Galaxy Nexus has a high-def Super AMOLED display--not to be confused with the Super AMOLED Plus technology found in the Samsung Galaxy S II line of phones. This 1280-by-720-pixel display is actually based on a PenTile pixel structure in which pixels share subpixels. Engadget points out that the Galaxy S II phones have full RGB displays in which the pixels have their own subpixels. This means that the Galaxy Nexus has lower overall subpixel density, reduced sharpness, and degraded color accuracy than the Galaxy S II. But according to site FlatpanelsHD, the Galaxy Nexus has 315 pixels per inch, which is slightly lower than the iPhone 4/4S at 326 ppi.

To be quite honest, the only quality difference I saw between the Galaxy S II, the Galaxy Nexus, and the iPhone 4S was in color accuracy. Colors on the Galaxy Nexus had a slight yellowish tint, mainly in pictures or websites with a white background. Otherwise, blacks looked deep, while fonts and details appeared sharp. Unless you’re crazy about pixel density or have insanely sharp eyes, you probably won’t notice the slight display downgrade.

The display is a roomy 4.65 inches, but really only 4 inches of that real estate is usable. The remaining 0.65-inch space is occupied by a customizable shortcut bar that appears at the bottom of the home screens as well as some other internal screens. Even so, the screen feels plenty spacious for all of your gaming, video, and other multimedia desires.

I think the issue here (at least on my Gnex) is that regardless of what I have the screen brightness set at... it goes to max brightness when I play a video in both google video player and MX video player.

Set your screen brightness to low - open MX and as soon as start a video you will see the whites get much brighter... they then go back to your setting when you stop the movie.

This seems to be a software issue not a hardware... so hopefully a dev can fix this.

Why do you think it's a software issue? I tried multiple players, including the built in one. I tried various movie formats, various compression levels and configured the players to use hardware, software and "software fast" decoding methods. They all exhibit the same blue artifacts.

The thing that sucks is now I have to pay a $35 restock fee and get a phone I don't really feel thrilled about (the rezound), but I guess I'll have to take all the bloatware and locked bootloader on the rezound and pray they get it hacked and I can run CM9/ICS in the future.

Really, really bummed to have to return this phone. I love every aspect of it, and I was ok with the slightly worse radio performance. But I guess this is just too annoying for me to live with, since I probably watch at least 1 tv show or movie a night, it's totally a deal breaker for me.

FYI, for anyone that claims they can't see it, look again when you're in a dark room. It's very difficult to discern in anything but extreme low light or darkness. I'm trying to figure out how I can show the CSRs in the store since it'll be super bright in there I'm sure.

sigh...after all this wait, I have to take it back.

Yup

I would report it as a bug, but I am about 99% sure this is a hardware "limitation".

God I hope the Rezound gets S-OFF soon....

What would I search for on google for this? I want to see if anyone else is reporting this on the GSM version since it's been out for a while now. I imagine it's the same, but who knows maybe it's an issue with only the LTE version (highly doubtful).

FYI - It is nearly impossible to see the issue if there is strong ambient light or sunlight around you. I checked the video again as I sit next to a window and I could not see any of the aliasing or artifacting at all. I could only see it when I went into a dark room.

Yep, exactly. Which means I'm screwed trying to show it to the CSRs in the store. I need to figure out a way to do this. Maybe bring in a shoe box and cut a hole in it or something? LOL, what a sight that would be...

How often do you watch your home tv at max brightness and expect a good picture and dark blacks (especially in a dark room)?

Unfortunately I don't know how to test what effect max brightness is having on pq as all of the video players i've tried default to max brightness when watching a video (regardless of what brightness the screen is set to)

I watched videos on my dinc every night probably for over a year. There were zero problems with the video playback. It's not like this is a problem with ALL phones out there. I don't know if it's a pentile thing or something specific to the nexus or what. All I know is my dinc did not have this problem and the video quality is much better and unfortunately it's not something I can compromise on, but that's just me. Obviously not everyone watches a lot of videos in the dark, but I happen to and it's really annoying.

I think your missing my point... Did you always watch videos on your Dinc at max brightness??

Not asking you to compromise.. just throwing out a potential cause If your unhappy return the Nex there are plenty of other good phones available

Could also be a defective unit... maybe try exchanging before returning? Hope it works out... no matter which route you go

Yes I did, except when my wife complained about it Normally she'd already be asleep so I did use max brightness. And nothing like this was apparent. I can live with not-fully-black black, but this is different. It's nowhere near black. It's not like a deep black issue, it's some sort of blue-ish artifacting when not-quite-black is on the screen and moving. Hard to describe, but once you see it, you will know what I mean.

I stand totally corrected. It may not be a software issue, but software CAN fix it (or work around it). I found an app called screen adjuster. I set it to various brightness levels (which overrides the auto-brightness in the video) and the blue stuff is there regardless of brightness.

However, bumping up the contrast DOES make the blue blocky stuff go away! YES! The blacks aren't quite as black when I do this, but I am totally ok with that. I'd rather that then the nasty blue aliasing that is apparent with normal contrast.

Ahh, this makes me happy. I'll tweak the contrast and post the optimal setting (lowest contrast setting that makes the blue stuff go away) as soon as I find it.

I'll post this to the "known issues and solutions" thread, but here goes:

- for those of you who watch movies/videos in a dark environment, you may notice blue/blocky artifacts in dark parts of the video
- to work around this, download the free app named screen adjuster
- optimal contrast (lowest contrast that blocks go away) for 100% brightness is a contrast of ~7%. Could go a little lower, but then the blockiness starts to manifest

Anyway, for anyone like me that noticed this, try out this free app. I am more than happy to use this workaround and keep my Nexus than go to a locked down device.

I may still file a bug with Google/Samsung on this. Seems like it MIGHT be fixable in software - even if it's just a built in way in ICS to adjust contrast.

Hmm, I actually couldn't see what OP was talking about in the sample vid. Even in a dark room, his hair looked totally black to me regardless of brightness setting. No blue hues to be found . My G-Nex is totally stock at the moment too. I've passed several color blindness tests too, so it's not that .

I'm glad you found a fix for your problem though.

Hmm, weird. Others can see it too. Did I get a bum screen? Others are seeing it, too, though. So if it's a bad screen then it's not an isolated thing.

I'd get hold of an MHL cable and play it on your TV.

If the blue is there, it's a decoder issue and maybe can be solved in software / firmware.

If the blue isn't there, maybe that indicates it IS an issue with the Nexus' screen?

it's kinda subtle and you'll only see it if you really look for it. in camera-land, this is like pixel peeping to see how effective the sensor is at producing true black and not having a lot of noise.

I would kinda think that this is a minor flaw within pentile compared to true super amoled plus screens and retina displays.

see this:

Super AMOLED Plus vs Super AMOLED vs Retina Display

and this:

Galaxy S II and Galaxy S screens compared at the subpixel level (video) -- Engadget

if you look at the macro shots you can see that the blue sub-pixel actually appears to take a larger surface area than red/green, this could account for the blueness we are seeing.

Ok so this is still really bothering me. the bump in contrast helps a bit for black areas with the blue splotches. but i am seeing nasty banding ( i think thats it) and what looks like slices of ghosting. its not in the same spot on the screen, and only visible in a dark room.during video playback. what IS this and what can I do about it? is.this just par for the course with amoled?

btw, i did swap my device out bc.of.the yellow hue you can see on the keyboard, but this one looks the same. is it possible the keyboard itself is a slight gradient? but yeah, this one has the same video anomalies i have seen. really annoying.

I was going to exchange my phone tomorrow due to the horrible traveling blocks ruining videos. I thought I had a defective unit. Now at least I know I'm not alone in my irritation. Tried the screen adjuster app but it did not seen to work for me. I had other small gripes I could live with, for example going to the camera from the lock screen does not work 9 out of 10 times. I could live with that but I watch a few videos almost every evening. I can't believe after sitting on my upgrade since July waiting for the SGS2, then when that never came, the Nexus, that I have to exchange it for a Razr or Rezound. I keep tellng myself its just a phone I should not be this sad about it.

Well I was ok with the other issues and would have been ok with this if I'd have had success with the contrast thing. But pretty much any dark scene is utter crap on this phone, I'm sorry to say. And it seems like out of focus areas show this line graph look to them. Is this what people refer to as banding? I honestly don't see how anyone can watch a darkish video on this phone without doing a "WTF??".

If anyone has a nexus and is in the bucks county, pa area and doesnt see this behavior in their phone, i'd live to see if people just dont notice it or if they just have a screen that works properly.

Default Possible issue with video playback quality on Nexus in dark/low-light conditions?

I know I will get flamed by people who are in denial or who just love this device to the point of not caring about the video quality.

But folks, if you are reading this forum and you watch a lot of videos on your phone, do NOT buy it. I really hate to say it, but it's the God's honest truth. The combination of pentile and samoled do not make for a good video viewing experience.

Whether it's the nasty blue blockiness in dark scenes or the banding/artifacts evident in video playback, it's simply not a good looking display for watching videos in dark/low-light environments.

By all means, if you watch in environments with more ambient light, you may never notice or care. But I challenge any of you folks with Nexuses to watch a video (even with full brightness) in a dark room and NOT see the nasty blue blocky artifacts in dark parts of the video and general bad video quality.

I REALLY want to keep this phone. I honestly do. I am willing to deal with the bad radio signal. But I watch too much video on my phone to "live with" this. I love the look/feel of the phone. I love ICS. I love the other features, and honestly the battery life is GREAT compared to my dinc. I just can't live with the video quality.

I'm more than willing to accept that it's a BAD screen, but this is my 2nd gnex and plenty of other folks said they observe the same thing:

http://androidforums.com/samsung-galaxy-nexus/465326-horrible-blue-aliasing-artifacts-black-areas-during-video-playback.html

I want to be wrong. I want to keep this device. But I can't get past this horrible video quality. At this point, I'm pondering either returning the nexus (if I can to a store in PA, when I bought in CA - the CA CSR assured me I can) entirely and hoping my dinc survives until the mid-year offerings or just getting the rezound. I dislike sense, and I can't really say I love the look of the device nor the thickness. But if I can get GOOD quality video @ 720p from that sucker and I will get ICS soon, I guess I can deal. Who knows if it's going to get S-OFF. God I hope so if that's the way I go...VZW is my only carrier choice, so I have to decide if I want unlocked nexus goodness with craptastic video or a locked device like the rezound.

major *sigh* here.

What video are you watching? I rarely ever watch videos on my phone but I'm just curious if it's something i'll notice when I do. (So what i'm saying is I want to watch the same video and see if I notice anything, i'm betting I won't)

~Skryre
Basically, anything that's set in a dark environment will show the problem (at least EVERY video I've watched has). Here's a sample video from the thread I mentioned which you can view for yourself. Again, watch in a dark/low-light room. I've observed the artifacts/issues with both full brightness as well as with the 2nd level brightness from the power app:

http://dl.dropbox.com/u/28717002/test.m4v

Like I said, I really want to be proven wrong, but EVERY video with dark parts I've view has this issue, and I'm just not going to sacrifice the ability to watch a movie/video/tv show without the crappy artifacts and banding/etc. But hey, for folks who don't watch much video on their phone, it's probably a non-issue. I happen to watch a lot of things in bed in a low-light situation and any dark video exhibits these problems.

I see the blue blockiness that people on here are complaining about, but I don't believe it is a screen issue. It only seems to manifest when the guys head is close. When the pictures moves further away, the blacks seem perfect to me. I would think if the issue was the display itself, that blue blockiness would rear its head in other areas than just in video. I'm not an expert or anything, but it seems to me that this is a video codec issue. I'd be willing to bet that this issue can be fixed 100% through software.

This issue isn't the same as banding. Banding is basically when you can see a strip running vertically or horizontally across your screen like in this image.

Well I dont have the phone, but after playing with it in the VZN store and comparing it SIDE by SIDE with the Droid Razr, it kicks major butt. I was ready to walk in and walk out with the Razr, but the video playback is what made me hold off and rethink my future purchase...Just saying.

I don't typically watch a whole lot of video on my phone. In the past I've watched replays of NHL games and the occasion Youtube video, but not much else. With this phone I've been viewing a lot more video though.

Maybe it is my eyes or something in my settings, but I just streamed about 8 minutes of Aeon Flux, Lord of the Rings The Two Towers and Limitless via NetFlix on my phone and they all played back really well. I wouldn't rank the video quality up there with my TV, but its a TV. Now I am in a dark room where the only other light is coming from my computer screens and I have the brightness set to auto, but it looked pretty nice to me. As I said, maybe it is just my eyes or that I don't really know what I am looking for (this is honestly one area I prefer to remain ignorant on personally).

Sorry it isn't living up to what you are looking for. I can say that I thought the Rezound also had an awesome screen, but that probably won't mean much from someone who still thinks the Nexus screen is really nice too. Good luck. I hope you find what you need.

I've only watched some youtube HQ stuff and some videos I've made. It looks unbelieveable to me. We all see things differently and each of us has different tolerances when it comes to things like this. If you know you don't like what it is showing you and your post states you "want to like this phone" then you've already made the decision. Now follow through with it and get something you like

What brightness are you using? The auto brightness is a bit aggressive in putting the brightness down to practically 0, which will create banding. In dark environments it's really common for it to go down really low.

I keep mine at about half brightness and videos look great with no banding at all. It's not really noticeable at 30% or higher.

ah 30 year olds playing highschool kids. Anyway, I see the artifacts but they arenot nearly as bad as you make them out to be. I find the lack of autocorrect to be a far.more annoying issue, seeing as ive had.to.retype.this a few times already.
