Hey guys, maybe you can help me with this one. I get a lot of banding on my grass live wallpaper even after multiple restores. Does anyone have a higher quality version or even a reason as to why it is such low quality? I'm running CM7 on a rooted, s-off MY4G. I use LP and have not touched any quality setting except overclocking the device to 1.2 ghz.
I checked the stock rom and the grass live wallpaper is smooth as ****. To be more descriptive, in the daytime the top part of the wallpaper has big banding ovals and you can see the colors do not fade smoothly. At night I can see the lines of the night getting darker behind the grass as if the fading is really low quality. I ever have the good screen, man! I searched everywhere but am not seeing too many other people with the same concern! Maybe it is just my device or methods. Either way, If you have a lead I'll take it.
from my experience, it's the rom. I am using the latest nightly of CM7 and I have terrible banding issues also...Might consider switching back to sense again
Has anyone figured this out? It really does look like ****. I'm on RC3 CM7

I don't watch Netflix on my phones that much, but i was bored today on lunch and decided to watch a Doctor Who episode. I noticed that the video playback was very dark and grainy (brightness all the way up). I'm sure others have noticed this as well but i couldn't find any posts about it. I know that the phone is capable of 1080p playback so i fired up an HQ youtube video and it looked anything but high quality. The pentile display could be the culprit in this case, but it seems like it would be the gpu because it still seems like the resolution is low. Thoughts? Comments?
Hd on my phone looks great. I won't deny the pentile display leaves a lot to be desired, but not on pictures and videos. At least for me.

The graniness during playback is a negative characteristic of the pentile display that some people notice and others don't. The graniness is greatly reduced (even eliminated) when you turn the brightness down. I would recommend turning the brightness down to the lowest setting. The photon's display is so bright that you will probably never need to turn it up.
I noticed the dark grainy too, I thought it was just the program I was watching.

I've tried that and the quality was a bit better, however the contrast ratio on this phone is so great that the darks are dark as hell. I don't notice the pentile "screen door effect" unless i am looking for it, or if it catches my eye for a split second. Oh well, i still love the phone, i guess the Iphone's retina display spoiled me.
I dont think its the videos or the software playing the video. Its the Display Technology Moto chose to run with. Ive been on 30+ android / windows mobile / ios phones and this phone has the worse Display I have ever seen.
Its great that the display is in QHD res but the colors are awful on this phone. Coming from Evo 3D / Nexus 4G those 2 phones alone have bright colors. Especially the Nexus since it uses a AMOLED screen.
The photon is a GREAT phone but the display is just crazy bad. All my pictures / videos don't have enough color to them which then give it that grainy look. Shouldn't have to turn brightness down but even while doing that, there is still grainy picture.
Ima hold on to the photon for a lil while longer and then might jump to GSII.

Oh boy, i think i can smell whats coming... sorry for starting Display War II.
The blacks being to dark is black crush. This can be fixed with software. Hopefully something like voodoo will come out to allow us to make these changes.
Also note that display also has white sub pixels in addition to RGB which is supposed to increase the perception of brightness without being brighter. At least that is what i understood.
Last note when watching netflix, 4g and wifi seem best. Not sure if the limited 3g bandwith could be lacking the addition black information making the blacks crush.

Black Crush. That is exactly what it is. Everything else in this phone is near perfect. GPS locks in seconds. Speaker for music is loud and clear. Camera takes beautiful pictures. The camcorder is beautiful also at 720p 30 frames per sec. Phone is beast. Only draw back i see is the display BUT phone is nice and bright while outside in direct sunlight. As for the display i guess thats when DLNA and Micro HDMI come in LOLOL.
Hey all, to start off I want to point out that I've done my research on the pentile display, and the way it handles lighting by replacing some of the pixels with white ones to make it brighter.
It obviously has an issues handling "normal avi's" especially when it comes to black crush (crappy detail for shadows/dark during video playback).
When playing the same video side-by-side with my nook color, I've found that the atrix seems to be a bit more saturated... (sample image below... sorry for the crap quality, but I think it gets my point across)
so my question is, is there any way to get rid of the black crush and change saturation levels on the screen of the atrix? I'm currently running stock 2.3.4. Do any other roms have a fix for this?
(as a sidenote, my phone options were either the atrix or the gs2, and both suffer from black crush... sort of disappointing considering the price tags of both machines...)
Which video player are you using, and is it the same one on both devices?

I'm using MX video player on both. I've tried a bunch of players... same result. Even the stock player seems to have the problem... so I think I'm just stuck with it.
My Atrix 4G compared to my GTab Tablet looks pretty much equal in color representation, being the Atrix 4G more natural and bright. I'm too using MX Player (at max brightness btw)
Anyhoo, I rather have my Atrix's Pentile screen than any of the oversaturated/overrated Super Amoled (+) displays that tend to burn-in quite fast with moderate to heavy use.
Cheers!

thanks for adressing that... but does the gtab suffer from black crush? :/ that's the only thing that turns me off about the atrix.. video playback.
Just wondering if anyone else noticed yet...
Before the new update you could switch power modes and notice a major decrease in image quality in power savings mode, then notice it get a lot better once switched to balance mode or normal...
Well with the new update it seems to be stuck in the poor image quality mode that it gave before while in power savings mode. Also switching modes has no effect at all on image quality.
You can only get good colors now with super IPS mode turned on.
Maybe it is just your TFP, I had no such issue before or after the update.
Maybe you just didnt notice... Before the update it clearly adjusted brightness and contrast of the screen when in power saving mode...
It no longer does this and seems to be stuck with low contrast and washed out colors. I had no problems before the update because I would use it on balanced mode which let the colors out of the bag. But now with the new update every mode looks washed out.
I noticed that too. I don't know if it is the lower or higher quality, but it doesn't matter that much. All I care about is this stupid dead/stuck pixel.
I think it did adjust brightness but I am not sure it adjusted "quality". And not everyone is going to notice or see a difference because if some people always use auto-brightness then I don't think their screens every changed when they switched power modes (I don't recall my friend's changing).
So while I do think you might be correct that the new update has stopped the screen from changing brightness when you switch between power modes, I am not at all sure about the quality.
I wonder if we can assign screen brightness and quality to the power settings somewhere now? (or could before?)
I remember hearing months ago that Nvidia had this new idea to save battery life with the whole dynamic contrast and brightness thing.
But after using the device as an ereader for a while, the constant flickering was more than I could bare.
I'm glad its gone, now I can read in peace. I didn't notice any change in quality. Color temp perhaps...
No this is not what im talking about, It would change the image quality... not just the brightness...
Making images more detailed and colors more vivid. But its gone now, strange and kinda of sucky...
Any TFP users that knows what im talking about please chime in.
Update:
It seems that the tegra 3 auto image quality is working (not in the modes but according to what your viewing) but I really wish they would just take it out all together..
If you have a dark colored wallpaper your colors will seem washed out because its adjusting the brightness, contrast and colors to be weaker.
If you have a white bright wallpaper your colors will be more vivid, sharper and screen brighter...
This is why the homescreen may appear washed out to some, and others dont see it. It all depends on what colors your viewing.

I see what you mean.i just updated for the very first time.Its not poor image quality but when i hit my buttons it doesn't do anything screen stays the same.
Are you able to compare it with another device? Try to have the same icon on your home screen on each device. For me the TFP is noticeable different (even with a white wallpaper). I compared opera,market and google music icons, they seem to have less color and appear washed out on the TFP.
I am glad you noticed what I am talking about with the modes.
Screen brightness adgusts on mine even with auto brightness on which is expected to help battery life, but I see no change in quality of images on mine.

If you didnt notice the modes adjusting this (colors and brightness) before then you may not know what I am talking about. Yes even with auto-brightness off it will adjust brightness but this is not what I am talking about.
Before the update it most defiantly changed the brightness and image quality in low power mode. But not it does not and appears to be stuck in bad image quality mode, If you did not notice this before the update then you wont be able to notice the poor image quality unless you compare it to another android device.
Notice how the colors are off and appear washed out in comparison.
Not sure if I agree. I spent quite a bit of time examining the picture quality prior to the update. I do not see any significant difference in picture quality now.
I have a pretty good eye for picture quality (I was part of a team who set the picture quality for KURO televisions).
I am very pleased with the picture performance of the Prime. What I would love to see is local dimming......

Don't notice a difference. Seems about the same quality to me.

I think he is finally on to something for once..lol. He is correct in the sense that the major change in contrast from balanced or normal mode to power savings is not apparent anymore. I described this change in contrast and detail in the first week Prime was received. Its not in permanent poor image quality though or power savings look. Before you could hit power savings mode and instantly see the screen contrast change, it wouldn't look as detailed. at first it would look like the brightness dropped a lil but its actually the contrast being adjusted. the icons would have a cartoonish look to them. then once you press balanced or normal mode it would instant switch back. NOW, there seems to be no change at all. like its stuck in either balanced or normal mode color scheme. I just switched various wallpapers, light and dark and colorful ones. its all the same. But there is no loss in quality though of pictures. we just don't see the change anymore immediately. of course when hitting super ips+ mode the colors and screen brightness gonna jump up. it's from the dramatic increase in screen brightness. which for me is too bright, especially at night time.
Good find though Jzen. I didn't notice until you made this thread. as I never use powersavings mode. I only noticed the change in the beginning because it was so prevalant. now the switch isn't anymore. Maybe like he said Tegra3 is doing it all automatically. I can't get it to look like the powersavings mode look like before though. Display still looks as great as it did before. just now the contrast doesn't immediately drop when putting it in powersavings mode. it is seeming like battery life has increased even more though somehow. if this is related to situation mentioned, then its a good thing as there's no loss in quality or contrast. Super ips+ mode is a battery drainer though. keep switching it on and off and you'll see battery life drop in multiple numbers. not just gradually one by one. lol.

I would notice as I was the first one to mention the drop in contrast weeks ago in various threads and my Different Performance modes thread. it is not stuck in poor image quality mode. you just thinkn that because you don't see the immediate switch and drop in contrast when going into powersavibgs mode. cutting on super ips+ will look dramatic no matter what before or after update so that can't really been used. you are only partially correct in your find. and that is there is no drop on contrast anymore. To me it seems as if its stuck in the balanced or normal mode look from before. cause before when contrast dropped in powersavings, all the icons would look funny and catoonish looking. now it just looks normal no matter what mode you in or wall paper you using.

corrrect but if people never switched the modes before then it'll be hard for them to notice there is no longer a drop in contrast when going into powersavings mode. its all looks great now what mode you in. maybe it does it very slowly and gradually in powerssvings mode so the change won't be so noticeable like before. either way Best Display by far of any tablet.
This is definitely not true for me. It is correct that the switching feature is gone, but it is not stuck in low quality mode. my screen looks as awesome as before. maybe you were in powersaving mode before updating and this is another updater bug?
Yes even with auto-brightness off it will adjust brightness but this is not what I am talking about.

Sorry if i jump in at this point with wrong subject, but - so this is a known bug on the prime? I already wondered about the automatically de- and reincreasing brightness while scrolling websites even if auto-brightness is turned off...

it is not a bug it is a feature seriously this is really intended, but maybe a bit buggy...
I notice my sig's image looks very blurry in the browser on the Prime than from the browser on my desktop PC.
My PC res is 1920x1080, with the prime having a lower res shouldn't the sig look better only bigger?
I ran the firmware update almost immediately after using my prime for the first time and connecting to my wifi. Didn't even think to look at images through it yet.
OT: I thought the clouds on the background image move. Perhaps I have been wrong from loving all the videos of this online. Will there ever bee a desktop background to have such a feat?
Ok this is my post from few days. So am not crazy? You noticed the same thing?
got a question about the screen. Some times I can sense and see that despite of auto brightness off that the screen adjusts its brightness by itself. It is a little change but my sharp eyes can see this... Do you have a similar thing? it looks like prime adjust the contrast / brightness by it self even if autobrightness mode is off. it happenes while watching youtube, browsing www or playing. it happenes like this on all 3 performance modes but it is more aggresive on battery mode (power saving mode)
Do you notice the similar thing?
i just recieved another update for my prime. The "feature" of brightness instability while scolling seem to be fixed, but yes - after using the power save mode and changing the background image i noticed a really poor color/compression in all backgrounds i set, doesnt matter which one. Restart and changing the modes to high performance or balanced doesnt help, same with setting up a live wallpaper for a while..
Now that the cat is out of the bag as to the cause of the DNA's color woes (kudos to beaups), I thought I'd throw something else out there. I've noticed now across both sense 4+ and sense 5 ROMs that the DNA employs some kind of very aggressive dynamic contrast algorithm as dark images or large amount of text moves across the screens while slowly scrolling though it, especially noticeable in browser applications, effectively cause a 'pumping' or manipulatable shift in display brightness. Obviously, this is most jarring when the majority of the background is white and darker areas are introduced. Also, it occurs both with auto-brightness on and off, being most noticeable at lower brightness in darker ambient conditions. I've used various kernels with the same behavior. I know that this feature is commonly used in media presentation, but it seems way overdone in general use outside of videos compared to other devices I own and have owned in the past. I'm curious as to whether this is possibly something kernel or OS related that could be addressed or a deeper issue. Thanks.
Finally, it appears to be present in the HTC One as well:
http://forum.xda-developers.com/showthread.php?t=2243483
im going to say kernel but dont hold me to it as i dont know exactly how the os controls that aspect of graphics
what rom are you on
I was on a couple of sense 5 ROMs, viper DNA, and now Carbon and all have exhibited this issue with different kernels.
Any other thoughts on this? It must be a source kernel " feature" but it still annoys the hell out if me.
Hey,
I've just bought a V30 today after my Nexus 5 started to have some issues to hardly use it as a daily driver.
After spending some time on it, I've noticed that the display is quite blured if you look close to it (it can be seen mostly on white backgrounds). It looks like watching a 480p image on a 1080p display in full screen. Everything seems to have lower resolution than it should have (note that I've tried to adjust brightness and resolution but it seems to be hardware related)
Is this normal? Is it like this for all oled displays?
Thank you for your answers

Are you talking about grainy looking? That happens on very white backgrounds in my experience. Shouldn't be blurry though. Any chance you are able to take a picture of what you are talking about specifically

Yes something like grainy, mostly noticeably on 50% brightness and white backgrounds but also on other colours (like there is a another layer between the oled screen and a display). Should I sent it back ?
@Klyno
From what I've read on the matter it seems to be just an inherent "quirk" for the V30s P-OLED display (kind of like the "Blue-shift" effect that happens when viewing the screen at a certain angle and beyond). There was a thread on here somewhere about the display that some people mentioned this. You can try exchanging but I'm not sure it will help. Maybe someone else can chime in ( @ChazzMatt frequents the V30 forums quite often so I'm sure he can direct you to the right thread). Maybe try the display thread under real reviews category
