I have the Acer Iconia on a test run..........I am somewhat peeved by the screen being just a tad bit washed out. I mean, compared to Galaxy Tab or even Asus EEPad ( I also have them for testing !!!). But Iconia feels more solid, and its very responsive - a big plus !! So much faster than the Galaxy Tab.
Is there any custom fix for the screen.........like a kernel fix or something that improves gamma or something like that....
Thanks !
You can't compare A500's color with Transformer or Galaxy Tab 10.1, the Transformer is IPS screen while the Galaxy Tab is AMOLED screen, both are completely different technology from the A500... and as you found out, both of these technologies do offer nicer color than A500's TN technology.

Uh.. just because they're different technologies doesn't mean they can't be compared. In fact, it allows them to be compared.
Comparatively, the a500's screen is pretty weak. I think a simple saturation boost would help it quite a bit.

what I meant is IPS and AMOLED is known to produce richer colors than TN screen, that is a fact - so don't waste time to verify the facts, I haven't seen any TN screens that can beat IPS/AMOLED, no matter how you tweak it.
Nobody said it had to beat it, stop getting so defensive. We just want it to be better.

I ain't defensive, it isn't my thread anyway.... I'm just saying you can't get it better if it's in the hardware, I just want to save your time looking into something impossible.
just a little input here. once chainfire 3d fully supports honeycomb/ics you may be able to write a plugin that adjusts the color saturation. i personally am waiting to adjust the color temperature as it is a bit cold.

That would be great! Mine has a blue color cast as well, it'll be nice to get rid of that. Out of curiosity, why has chainfire 3d got anything to do with this? I don't recall chainfire 3d having any color adjustments?
Hate to burst bubbles, but the Galaxy Tab 10 does not at all have an OLED screen... it's an LCD... they have a 7 inch tablet coming out with Super AMOLED, but Samsung isn't even producing 10" OLED screens yet. It's just a much brighter, more colorful screen, but the colors almost seem unnaturally bright. I kinda like the more natural tones on my A500's screen.

cf3d has a day and night setting. the night setting allows you to adjust your color settings. if you lower blue you then bring up the color temperature
this is the only non cm7 way i know of to adjust your color settings cross rom

ic, I haven't got the pro version of chainfire 3d, I think this setting is only available on pro version.
Anyone know of a way to adjust screen colors on Nexie-7? Comparing GoogleTalk on it to GSII, colors are way, way washed out and pale. I appreciate that some of this is IPS vs. Amoled, but this is really pronounced.
Any suggestions?
Thanks!!!
There does not seem to be a way to do it yet. This question has been asked many times since release and there is nothing to even show it can be done. Its looking very unlikely that we will have such feature. Would be great though.

I have a hard time comparing the screen to a device like that because I'm really not a fan of the over saturation of colors. Something that looks like I'm on acid at the Willy Wonka factory just doesn't appeal to me. On the other hand, it'd be nice to have color control capability on the Nexus 7, but I'm extremely doubtful any adjustment capability will be possible.

Hi!
im going to get the N10 in the next week and the first thing i will do because im a color junkie is a calibration test so se how close/far it is from
reference.
i have been into hardware calibration for displays for some years so i see myself as a pro.
i have X-Rite Display 3 Colorimeter and Chroma Pure calibration program.
http://www.chromapure.com/
the test patterns i use is from AVSHD709
http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration
i have already calibrated my LG Infinia LED TV to reference quality,so if only the right (ISF/CMS) settings is there i can calibrate any display to near reference quality.
but its all about the settings how much you can change.
so the question is:
is there a App that i can change the RGB values and saturation/hue also gamma settings?
or do i need to get a custom rom?
i know some custom roms for the SG2 has some screen/gamma adjustments in EX tweaks.
if its not i will still post the results from the calibration so you can check it out to see how good/bad calibrated the Nexus 10 is
Edit: i just found one
http://forum.xda-developers.com/showthread.php?t=745248
but i need this for the N10
Theres an app in the play store called Screen Adjuster that allows to change RGB, contrast, brightness but requires root. Been wanting to try it but I cant root my tablet as my pc wont recognize my tablet in fastboot.

Apps on the market only apply a filter on top of the screen. You're going to want a kernel with proper color calibration support to prevent performance loss.

thanks for the link
interesting
damn the Nexus 10 is WAY off in the Gamut Chart!
how the hell can they release a screen thats is so off?
surley needs some calibration there
fix a kernel with RGB adjustments and i will fix a calibration that is better than on the iPad4.
after that you can just copy the settings and BOOM you have a reference display.
(that is if the screens dont differ to much)
i have the tools and the Knowlegde to calibrate displays but zippo knowlegde in hacking kernels
so Kernel Experts
MAKE IT HAPPEND!
Edit: first thing you will start with is the grayscale
when the grayscale is right (whites is white and not blue) then automatic you have your 6500k color temp (6500kelvin is messured from daylight in california if someone wants to know)
Also the Gamut is adjusted in position.
so its easy
with a correct grayscale everything (almost) else becomes right on spot.
one setting that they dont test there is Gamma
gamma at 2.2 is important if you want to see all details in darker parts of movies or photos.
gamma is adjusted with all three sliders Red/Green/Blue locked
So what i need is RGB adjustments and Saturation/HUE adjustments if its possible
comon hackers
we must beat the iPad!
If you want to have ICC support in kernel you've to ask a kernel dev. But I don't think that someone will implement this feature. Because the majority of users doesn't know or care about correct colors.
As the test results of your linked page show the N10 reaches a "good" neutral in white, gray and black. But the contrast is very low and by calibrating and profiling it you'll reduce it more. You've to calibrate D65 at 120 - 140 cd and after this to write a correction profile especially for blue and violet tones.
Apple does such things because their customers want to have and need good colors. But I don't see a market for android users. Photoshop touch is crap and there is no other "real" graphics suite / app. Given gamut is okay for daily use, e.g. viewing movies and surfing around the web.
So, don't be disappointed if your wish to cailbrate and profile the N10 won't be possible at all. An google seems not to have plans for ICC support in android, see https://groups.google.com/forum/?fromgroups=#!topic/android-developers/Ifnsdbkqxqo
The only thing that really seems off is that it has very washed out purples. Its fine other than that. It strange as it can display blue and red just fine.

Fortunately a lot of devs seems to think different seeing the amount of stuff they've coded that average Joe doesn't know or care about.
I for one would love to see the OP succeed as i see nothing wrong with getting better colour accuracy on my N10.
I personally really hope that a color calibration app/kernel becomes available.....devs PLEASE make it happen!! I like the punchy (albeit 'ficticious') colors of the amoLED display on my Galaxy Note....Please devs, give us the option to control/enhance the color of the Nexus 10's screen!
Another shout for some calibration tools on the nexus 10. All my main displays are calibrated & it's quite a shock to pick up my nexus 10 & the see the washed out colours
Indeed, the guy who mentioned the fact that the average Joe doesn't care about color reproduction is forgetting the fact that not a single one of us here is an average consumer, I also own an iPad 3 and I really loathe the washed out look on our display, the iPad looks very similar to the calibration I have on my Sony TV while the nexus looks almost like a color less gray when its put beside them, they all look like crap when you put them besides my SGS 2 though, all I really need to be completely happy with my Nexus would be a way to calibrate our screens, I have already pretty much given the iPad to my little sister but I hate to admit that the colors there look much much better than on the Nexus.
And by loathe I mean that I completely hate and despise it, such a great display ruined by the damn color calibration, the option should be built into Android for ****s sake.
PLEASE devs make it happen, color calibration seems to be an issue shared between all of the recent Nexus devices, for example, the screen on the Nexus 4 doesn't look as good as the one on the LG Optimus G (Or so I've read)
It's a shame Google are apathetic on this issue. Users that want do photo work are forced to go to Apple. Small OT aside: It's the same deal with audio creation apps/interfaces, Google doesn't care. I'd rather set my sites on Ubuntu.
Another vote for getting some kind of good calibration tool for the N10. I can put up with a lot, but the black levels are killing me. I would even put up with some loss of detail if I could get better black levels.
So... Guys, how can we contact Google to ask them to fix this themselves or do something so we can fix it ourselves?

Nah, the screen on the Nexus 4 doesn't look as good as the one in the Optimus G and the screen on the 7 is kind of washed out from what I've read, and from past experience I've seen that Samsung tends to calibrate their screens pretty nice, (albeit a bit saturated) on factory settings across all devices.
Hope someone can sort out the black levels, watching movies the blacks look grey specially with Dark Knight! Tried all sorts of things but nowt helping!

It's a shame for Google not calibrating any of their screens. Nexus 4 has those ugly washed colors, same with the nexus 10. And black levels, despite as many synthetic tests you will post (anandtech etc) are quite bad.
I'm so sure this is software... and 0 upgrades from Google. Its ok they will push next version of android as soon as avaliable, but nothing else, no OTAs for bug fixing. Any other brand would have already pushed several upgrades to new devices, bugs appear and samsung, htc etc gives you solutions (not always, but...)
Excuse my ignorance, but how great of a screen is the N7 supposed to be in comparison to some of the higher end smartphones out there in terms of color reproduction and saturation?
I have the HTC One, and side by side comparisons of the same image makes the N7 look washed out and bland.

That remains to be seen until LaptopMag or Displaymate or someone with the tools can accurately measure it, but reviews so far point out that both brightness and colors are very good on the device.
Be cool if ISF calibration could be implemented into tablets & phones.

Didnt the N4 have some color correction tuneable built into the kernel? Since the N7 mk2 is on a similar SOC, I was hoping for the same.

The N4 color out of the box was terrible. Not to long after launch a few devs implemented a much better solution baked into their kernels. I would expect the same here. The N4 gamma and color is brilliant now

It's pretty good on par with iPad 4 according to Anandtech and Apple is known for having good calibration. But then again, just a matter of time when we can calibrate it ourselve like the Nexus 4.

I agree with you completely. I have an HTC One X and immediately thought the 2013 N7 looked pale in comparison. Hopefully there's some resolution in the future.
I have a Note 8 and a Nexus 7.
On colors with green elements displayed on the Nexus 7, the entire photo takes on a distinct greenish hue. The black level on the N7 is not very dark, either.
I set up both tablets on the floor, mounted a camera on a tripod over them and took photos.
Attached are some detail shots of flowers and our dog showing the green wash and the bright blacks. I certainly hope that this is something which can be addressed in software.

(fullsize image; nex 7 images at top, note 8 at bottom)
thumbnail preview attached.
I would definitely want to look at the N7 side by side with something else at the shop before buying one, or else be ready to return it if you have trouble with the color accuracy once you get one home.
Not everyone will care, of course.
But what I've seen in reviews is that brightness is good but color is not very accurate, not that both are good.
roustabout,
thank you for that.
that proves my point from other threads, the N7 screen is not properly calibrated yet again.
Overall, it seems pretty good to me. I compared it to my Spyder calibrated IPS monitor and the colors were fairly close.

They managed to bake it because LG left some display colors related things in the kernel. That said I would like to see if asus made the same thing for this device. (hopefully)
The view angles and color are excellent on it. Much better than the first nexus 7 and a million times better than the nexus 4.

That's what I've found: it looks a lot better than my Nexus 7 2012. I think it gets slammed a lot for being "bland" since most of the smartphones like to oversaturate their displays (I'm looking at you, Samsung). I have a really good IPS monitor for my computer, and it seems to fit in quite well with it, and it makes my Galaxy S4 screen look like a colorful kid's toy.

Asus provides a screen calibration in the setting on the Asus Padfone 2 & Infinity (Stock). So its likely possible.

Pretty sure the issue with the first generation nexus 7 was that nvidia didn't provide a way to set these things. Qualcomm I believe does so the odds are pretty good. I personally like the stock calibration though. The first time I think its been good on a nexus device. The panel itself is much better than the nexus 10 and nexus 4 as well. Much wider view angles.

No display is ever "accurate." The question is which colors of the spectrum are closest. Here's the N10.1-14 (left) against the N3 (right).
Here's my N3 displaying the same yellow background as my N10.1-14
And actually the N10.1-14 does better than the N10.1-12 on whites; at least the example Anandtech tested.
i noticed my Google Keep and IMDB icons were alot darker than on my old touchpad

This is from Anandtech's review of the N5. There's been lots of grumbling in their forum about "washed out" colors.
It’s interesting to hear some Nexus 5 users complain that the display seems undersaturated, since that kind of end user feedback reflects subjective comparison. It also suggests to me that a large percentage of the population doesn’t know what some colors or system elements actually should be. Even for me, looking at the green elements inside the Google Play store on the Note 3 in movie mode or Nexus 5 initially seemed slightly more muted than normal. The reality is that this is what they actually should look like. We’ve just become accustomed to their oversaturated appearance on virtually every other device.
This kind of expectation about what looks right and what doesn’t is rather telling for the state of display calibration in Android handsets, and how OEMs have used oversaturated colors to increase retail shelf appeal. Unfortunately the reality is that oversaturated colors do seem to win taste tests among shoppers, the same way that TVs in most big boxes do. We’ve been looking at them for so long that well calibrated displays like Nexus 5 initially do look noticeably different.So I don't know if the N10.1-14's yellows are closer to "right" or not but they are certainly close to the N3's. I'll admit I like oversaturated colors even though I know they aren't real. Assuming the N10.1-14's movie mode is closer to natural like the N3's try using it for a bit. It does look washed out even though it's technically more correct. Exaggerated colors on a small display actually have an advantage via greater separation from each other making things easier to view. At least IMHO.
I I think most colours are pretty natural on this, which you find with lcd. I love the screen though
