Title, pretty much. I change my color settings and they only apply to the dual screen when attached, and not at all when disconnected. It's the exact opposite with specific game settings. I can change a game's resolution and framerate settings and this works on the main screen, but NOT on the dual screen. When I swipe the app on lower settings from the main screen to the dual screen I can see the resolution increase.
EDIT: Specs - Verizon model, newest update. Which I'm irritated about because I kept myself on the base firmware this whole time waiting for root and finally gave up, hoping it would fix this, along with a plethora of other issues. It fixed some of the minor ones, but not the big ones like this or others.

First off, grovelling apologies for what is probably a painfully newbie-ish question - I am entirely new to Android phones. I have tried searching - came across this thread, for example: http://forum.xda-developers.com/showthread.php?t=1124669 - but haven't found much in the way of practical solutions yet. This may conceivably be more of an "Android question" than a "Galaxy S2 question" as well, I'm not sure....
Anyway: one of things I use my phone for an awful lot is watching videos. What I'd like to be able to do is get the the display a little closer to a properly callibrated TV - so the whitepoint should be somewhere near D65, proper white balance across the whole grey-scale, the gamma somewhere near 2.2 across the scale, primary colours not too saturated, and so on.
The main problems at the moment seem to be that the white point is pushed quite badly towards the blue, and that the green primary colour is oversaturated (this is in line with the findings in the thread above). So my question is: what can one do about this?
I've investigated the "Display" settings menu, and discovered the "auto-adjust screen power" option which (again, according to the thread above) improves the gamma (reducing black-crush) at the cost of somewhat reducing maximum brightness. I've also spotted the "background effect" option; setting this to "Movie" makes colours a bit less over-saturated, but green saturation still isn't right. And within the standard video-playing application I've got the "colour balance" set to "Warm", which helps with the blue push a little, but not enough.
Are there any other display adjustment/callibration options that I've missed? Are there any apps which allow the display characteristics to be tweaked? And are there any 3rd-party video-playing apps which allow more precise callibration of the overall colour balance without compromising playback performance?
I just compared my buddies TouchPad to mine and his screen is MUCH brighter, mine doesn't seem very bright at all. Yes, I'm aware of the option on the top right to adjust the brightness level
We're both using TouchPad 32GB 3.0.2., i'm overclocked to 1,7GHz, he's on stock kernel.
Any ideas?
Open up the app launcher -> Settings -> Screen & Lock -> Disable Auto Dim.
This should also have been posted in general, it has nothing to do with development.
There are two different types of displays.. I have 3 TP's in my home and one of them is much brighter and displays colors in a different shade.. I wouldn't see that one screen is better than the other though
Thank you for your answers guys and sorry for posting in the wrong forum.
So there's nothing i can do about that? I disabled auto-brightness but there still is a difference.
The screens are just different and that's it?
Hi, curious question.
I'm wondering why the Nexus7 doesn't allow you to slow scroll/pan down at single pixel steps. Always seems to be in 2-3 pixel jumps. I got a bad habit of scrolling web pages while reading from iOS but on my N7 I get these kinda anoying start/stop jerks.
Is this related to the virtual pixel resolution being lower than the actual screen resolution? And would changing it allow one to match the virtual pixels to the screen pixels and get smoother slow speed panning?
Anyone know if some custom ROMs optimize for this?

I have been struggling with this issue for days. Looked into kernel code hoping to find anything related to scrolling or touchscreen but nowhere to find such a thing. It has nothing to do with virtual pixel resolution. If you swipe your finger at a degree of between 45-90 (accapted as scroll up by the system), Y coordinates change by 3 pixels where as X coordinates can change by 1.. Therefore its not a limitation, it is kind of scroll sensitivity which is 3px.. I've seen other devices can scroll by 1 pixel.
I believe google has set this value to 3 because of rendering issues, since its gonna render the screen 3 times more if it is set to 1. Maybe it is the optimum sensitivity. Lower than 3 pixels may disrupt buttery smoothness but its just a guess..
I hope one dev can lead us the right piece of code where it is set to 3 and we can change it ourselves to test the best..
You guys can try the problem yourself actually by installing the "Multi-touch accuracy check" app from market, which shows the exact pixel of the touch..
the xy coordinates readout from the developer "show touches" setting shows the 3pixel increments too.
when panning something just a bit faster than dead slow then suddenly gets rid of the jumps and goes smoother as well.
could it be a battery saving thing that they just get rid of taxing the cpu/gpu when people like me do these constant slow scroll pans on webpages and books etc.?

2 more thoughts:
a) this relatively coarse sensitivity can lead sometimes (not often) lead to a +/-3 pixel uncertanty in a UI element and cause it to jittter - sometimes happens when finger pressure changes.
b) I had for a while thought that it may be linked to the size of the touch sensors on the display. Being a lower cost device I figured that the HW resolution may be lower than pixel count. But I'm pretty sure that you must be always hitting multiple sensors and the system should just interpolate to a finer resolution.

When scrolled a little bit faster, it still increases by 3px , not 1.. I also assume that it is about battery saving but if I can find a way to decrease the step size, I'd love to try it by myself..
Also It can be related to the sensors , as you mentioned, but not likely.. It can catch 1px changes when swiped horizontally..
Any news on this?
As far as I can see, this is only related to touch screen; if you use a usb mouse, you can actually see the scroll by one pixel at time, and there is no graphical issues. With mouse all seems smoother...
At this point, I think It's an hardware issue of the touch screen, as the system can easly support 1px scrolling

My two cents...I tried this approach and when you move your finger with about 5 degree you can get 1 pixel change by Y and 3 pixels change by X. And if you move your finder with about 85 degree you get 1 pixel by X and 3 pixels by Y. It seems that hardware can handle the 1 pixel change by X or Y. It looks like the touch events are throttled by the system based on the distance between points.
There is no decent and satisfying answer to this yet .. I'm still waiting for a solution..
Odd issue i've got on my Z Ultra, easy to replicate by doing the following, bring up chrome, click the address bar, with nothing entered in the text box, but then type something, an the white box drops down, with search suggestions, I can see the brightness increase on my screen, clear the text box, brightness dims back down very easily by staring at the keyboard while this is happening.. is this a hardware issue, or software related? anyone else notice this? very strange. its like more white content on the screen, the brightness kicks up.
Seems normal from what I notice. If it bothers you, turn off auto brightness.
It's part of Sony's dumb LCD optimization gimmicks
It's equivalent to auto contrast used by TV's and LCD computer monitors
You'll notice your brightness goes down when much of image is dark, and you'll notice the brightness goes up when viewing white images
This doesn't happen on custom roms based on Aosp (like slimrom which I use aand prefer)

Wow this is crazy, I just noticed my phone doing this a couple of days ago, and here's this thread. While I do find this dimming "feature" a bit irritating, it's hard to complain about the screen on this device. It looks so damn good.
This feature is called optimized backlight and you could disable it in settings on android 4.2.2 (correct me if im wrong) but since android 4.3 sony removed option from settings menu and they enabled it by default, unfortunatly you cant disable it unless sony returns this option in new android version or if you downgrade to android 4.2.
Sorry for my bad English
I was really happy with my LG G5, until after a week or so, I noticed that the screen actually seems to have problems with "fast" change of movement. And I am really annoyed at this point by it, because I compared it with other devices of mine, and it's not that bad on these older devices. For example my old phone, a Samsung Galaxy S3, doesn't have this issue at all.
You can easily notice it in the Android settings (use list view). When you now slowly move up/down with your finger, you see that all fonts have a "ghost-effect" (get blurry) of not properly refreshing in time. There is a bit of border / re-draw affect around each word on the screen.
You will notice it also for example on the app store scrolling down / up, or in an app drawer (if you have a launcher with app drawer) and scroll through the app list.
On my phone i have no ghosting or problems with fast change of movement. There is a website called "testufo" where you can test your display for ghosting and FPS.
