Sensitive eyes and black levels

I just picked up a Galaxy Nexus from WIND Mobile.
I have to say, the one thing I dread the most about AMOLED is the black/bright contrast. My eyes are very sensitive, and whenever I see something bright against an intensely dark background I get halos and it's very difficult to focus. For this reason I prefer LCD screens where the blacks are slightly grey. Nonetheless I decided to make the leap to the GNex because I like a lot of other things about it.
Do you think there is any sort of hack that could make the AMOLED look a bit more like an LCD? I realize this would affect battery life but basically what I'd like is to hack the colour space so that black becomes maybe 1-5% grey. I remember on CM7 there were hacks that could apply filters to make white into a more salmon-pinkish hue, a warmer white, etc. What I'm looking for is the reverse - leave the white alone but make the blacks greyer.
Anyone think this might be possible?

I don't know a specific solution, but here are some options:
If you're rooted, francois kernel and app can adjust the Gama levels, affecting all colors, but may help.
App Log graph can adjust your auto brightness levels.

Yes I am rooted.
Does increasing the gamma change the black levels? If so that could help.

It seems to depend on the app. Some apps have a gentle dark grey gradient in the background. But the stock taskbar, even at full brightness, is just as black as the same part of the screen is when the screen is off.

Not trying to be a comedian here, but have you gotten your eyes checked lately?
Seeing halos is linked to several severe eyediseases or wearing wrong/none correction.

+1. Yup.

Fair enough. Optometrist says my eyes are healthy but I have large pupils that don't contract very efficiently. As a result I get halo effects at high contrast even when using proper vision correction. It's not something that poses a health threat otherwise. But he did advise me strongly against laser eye surgery as there would be a high risk of halos getting worse.
So that's me in a nutshell.

Super dim is a root app and it can lower the brightness below the normal values

I'm not looking to lower the brightness - I know how to do that already. I'm looking to decrease the contrast by making the black levels greyer.

HD Netflix?

Is there an HD Netflix app for our phone?

If you go to the website under your settings you can change the quality level.

Quality is usually adjusted on the fly but being a phone that in portrait only has 480 lines of resolution I wouldn't expect it to offer streaming 720P plus anyways. Watching on Wifi or good 4G should come up great but bad connections and 3g it will come out overly compressed.
Resolution is one issue and bitrate is another. The bitrate is adjusted based on connection speed to prevent buffering.

You probably won't on such a small screen but its the only solution that I can give to the question. Our screens aren't even HD anyway.

Using tubemate I can notice the difference between 480 all the way to 1080 easily and even on he fastest wifi there's no difference between the settings in android app
A big difference in ps3 app tho
I wish ps3 and android Alps had very own settings for quality like hulu plus apps do

Agreed. I think that netflix looks great on our screen considering the size. Definitely have to stream over wifi, sprint just isn't fast enough otherwise. Perhaps going over 3g is leading to poor display quality

Nexus 4 Display control

Has any of you tried this app yet? maybe its useful to get rid of the yellow tint of the nexus 4? It was made by Francisco Franco
https://play.google.com/store/apps/details?id=com.nexus4displaycontrol

Judging by the reviews it should work. I know im getting it once i receive my N4.

It does work. I just don't know what each setting combinations look the best.

I don't notice yellowing yet. Guess if it appears, I know how to fix it now. Since it looks like software, why isn't this fixed?

Can someone post their settings for this app. Black's are too light and colors not as vibrant as when using cm calibration settings on the previous nexus'

This is a different type of screen. Blacks will not be as deep nor colors will it be as saturated as super amoled. As far as settings I use 255 190 255.

I use Fauxclock. It's got CPU/GPU clock and voltage control, in addition to color (and gamma, when ROMs/kernels begin to support it). You can also select an IO scheduler.
Basically it does all the same stuff as Voltage Control, SetCPU, Incredicontrol, and N4 Display Control, but it's in one app so it's overall cheaper.

I went to a Best Buy today and compared my N4's screen directly to a Optimus G. I didn't actually think my screen looked yellow at all until I compared it to the Optimus G. My N4's screen looked terribly yellow, was less bright, and had worse viewing angles than both of the Optimus G's my local Best Buy had on display.
Based off the first post in this thread for the GNex, I set my Nexus 4 to settings of:
182
190
200
I haven't tinkered too much but this seems to make things a bit better.
Has anyone else experienced the screen turning very yellow, almost brown, when viewing from the corners of the device? I am pretty unhappy with the viewing angles on the phone, especially after comparing it to the Optimus G, which is supposed to have the same display.

Do you think there is a limit set on the brightness maybe a dev could unlock that limit to make the phone more brighter

This app puts an overlay on top of your screen, so it doesn't really "change" your display colors. Also: the overlay should disappear when you try to install an app because of the security issues with having one in place when trying to install an app. I believe Lux and other similar apps do this too.

But why you can't see it on a screenshot then?

The screen settings definitely do not change when you attempt to install a different app.
Why do you say this is just an overlay? It is baked into the kernel.

SCREEN FILTER: Dim/Darken Screen app

I read this up yesterday and wanted to post it here too for those who don't know about the app yet. "Smart Filter".
This app is magnificient in that it doesn't tweak hardware functions, but it applies a dark layer. Thus making it work wonderfully with the OLED screens (Apparantly OLED can only be dimmed to a certain extent).
This app is fantastic for reading, viewing videos or taking notes at night. Also awesome for using your phone in the theatres (I guess?).
Once again, app is called: Screen Filter

i use this app alot. great one because i too could not figure out how to lower the brightness.

Thanks for sharing!

I have tried many screen filter apps, and to this day, none have come close to Lux Auto Brightness.

Does Lux apply
a filter as well? The only down side I can think of with the filter method is that it doesn't really save battery (in comparison to actually emitting less light).

I dont think it applies a filter. I think it allows you to go below stock settings.

What display settings do you use?

What display settings do you use.
Right now I'm using Standard with the change color tone to save battery option. But my second favorite would be natural with the color tone option off.
I was reading that if you use Movie mode and turn off auto tone, you get the most real looking pictures and the best contrast ratio. It beats the IPhone display in every way, contrast and real color. I tried it out and it made the display look like a LCD display. It was kinda neat. Using those settings with an iphone 5 side by side to my Note 2, the Note 2 looks way better. But still, I'm not really into the washed out look of LCD displays like the iphone 5's.
Anyway I'm just wondering what display settings you guys use on you're Note 2.

i like real colors, so i try to use whatever is best for that goal.
actually, i use natural, without the auto adjusting. looks the best imo

I was using dynamic, but I've switched to movie. I like the way it looks.

I always use standard, but ill try some of the options.

I also use dynamic and just tried using Movie. Looks weird to me, everything seems...washed out. I'm sure you get used to it after awhile but everything looks so crisp and vibrant under dynamic.
Think I'll just stick with that.

I use natural. I prefer the look of my s3 but it sits in the middle of standard and natural. Standard and vivid are just way too saturated for me. Movie is slightly more dull.

Yeah I don't use Movie mode. I was just saying what it does. Maybe for people that came from the Iphone and want the screen to look more like there old phone.
I just use standard with color tone to save battery on. I really can't tell a difference with battery life with it off though.
