Does It Affect our HD display? - Samsung Galaxy Nexus

our nexus display density default is 320.. while slimrom is set to 245.. just wanna ask does changing the density affects our HD view on our screen?

HD view?
a maguro sent this.

As far as I know and what makes common sense for me, the display density that you set in software only dictates the size of the graphics and has nothing to do with the actual resolution of the display. The driver will still sent 720p graphics to the display, which will still be 720p.
The only thing that might be changed is the quality of certain bitmap graphics that, due to interpolation, might look a little bit worse in certain conditions. But that's unlikely to be noticed in day to day life because of the size of the screen and pixels and the distance from they are being used.
Cheers!

LCD Panels - Some Answers

Ok I have seen a lot of confusion over the months regarding the LCD Panel fitted to the Kaiser, I will attempt to answer most of these issues here.
Hardware: The kaiser series is fitted with a 2.8 inch 240x320 TFT LCD panel, which means that it 240 pixels wide by 320 pixels deep, the optimum density of this LCD panel is 143 Pixels per Inch.
Resolution: This refers to the screen resolution that the Operating System will use to display on the LCD panel, the 3 most common being 240x320, 320x428 and 320x480, the reason this is possible is that the OS is capable of fooling the display into using the fixed 240x320 panel to display more pixels, ( it does not really have more pixels, it just looks like it).
DPI: DPI or Dots Per Inch, also known as Density, and correctly known as PPI or Pixels Per Inch, this refers to the number of pixels the screen displays in a One Inch Square on the screen. As I noted above, the actual PPI of the LCD panel is 143 PPI, this is fixed by the hardware, and cannot really be changed, however since the LCD is software driven, it can be persuaded to look as if it is displaying more or less pixels in that same area.
Panel Type: This refers to the actual LCD panel fitted to your device, there are 3 types fitted to the Kaiser series, one manufactured by Sony, the other two by Topoly. While the 3 different types of panel are functionally identical, they differ at the electronic level. On Windows Mobile this difference can be detected by the OS, however on Android this is not possible, so the panel type must be set in the parameters passed to the kernel at boot time, either in default.txt when booting from SD, or hardcoded in the NBH when booting from Nand. Also there is no easy way of telling which panel type is fitted to any given Kaiser, since the panel type was chosen by HTC depending on price and availability and stock at the time of manufacture, so any model of Kaiser can have any of these types fitted.
The main problems encountered with the display are usually solved by changing the Panel Type, either by editing default.txt, or reflashing the correct NBH, ( note that you can also edit the kernel parameters of an NBH using a Hex Editor, however this would be a relatively advanced method, since an error could cause major issues).
Changing screen resolution and density: As noted above there are 3 main resolutions used, 240x320, 320x428 and 320x480. These easy to change either by editing default.txt, or flashing an NBH, depending on how you run Android, resolution is usually a personal choice. Density is not as easy to change, although Rogue Tools by Myn, (available in Market, and discussed here: http://forum.xda-developers.com/showthread.php?t=667581), is excellent for this purpose, there are various common PPI settings, and again mostly personal choice, a little experimentation with resolution and density will allow you to find what you prefer.
Hope this helps clear things up a little
Thanks for this, it helps alot!
vertical lines issue
just to add to the above: the vertical lines issue some have is related to choosing the wrong panel type. Chosing the correct one will solve the problem.
Wrong panel make errors display, ok! But Can it lead to additional consumption of the battery?

I suspect it may, since display errors such as vertical streaks, pixel errors, colour issues etc are actually caused by a mismatch between the OS drivers and the actual physical electronics, and it's possible that the panel may demand more power than it would normally, I'd have to bench test this to be sure, but it's probably easier just to use the correct panel type setting.
The correct panel type should lead to a 'normal' demand on the battery.

I use panel 2... I go to use panel 3 to test this. panel 1 make for me pixel errors. I'll report here.
Thank you
EDIT: no difference between panel 2 or 3 on my kais130
Thanks! That helps a lot.
I havd a thought, which is to change a physical LCD panel for my kaiser, HVGA or VGA... Is that possible? I would look into some electronic files later...
i guess that our chip has max resolution only 320x240 so no higher resolution
but as I look in the pdadb.net there are some devices with higher resolution and same chipset as ours so perhaps it is possible
It is unlikely to be possible to use another panel, since there are a lot of differences with the interface, it's not just the chipset, but how it's wired, plus higher resolution panels may need extra address lines which are not present in our kaisers.
For those of you experimenting with LCD Density settings. You may wish to try the following density settings.
100
121
144
169
196
Remember, pixels are square, so the density settings should reflect this, also the extreme ends of this table are just that, extreme

density 106 works very well with 240x320 if the build is designed for 320x480. I'm using that on the CyanogenMod port. Haven't tried it with other builds though. I did try 107 once with another build but that did not turn out very well.
106? that should really look a little blurry, but I think it depends on the resolution that the build was designed for, however I think I'd find it a little small personally, have you tried 100? it should look clearer than 106, although I have noticed that some people just prefer a certain density regardless of the actual mathematically 'correct' one.

So how do I detect which panel in winmo?
I don't like the idea of just stabbing blindly in the dark and hoping I get it right.
Basically? Stab in the dark, there is no way in wm or android to know which type is fitted, type 2 seems most common, and is usually a 'safe' default, if the graphics/colours are wrong, you probably have type 1, if you have issues waking from sleep then you probably have type 3. So try panel 2 first.

I'm running Android on my HTC Tilt and am using panel 2. I tried panel 1 and the colors were off so Panel 2 seems good.
But the problem I am having is that when I open up the dialer, it doesn't fit correctly on the screen, the bar which shows which numbers you have entered covers up the numbers 1,2,3 and the sides are cropped.
Everything else seems to be fine why is the dialer messed up?
Should I try changing density its at default right now.
I personally like to use 110, but every time I open detail application on Market, it gave me force close. Facebook for Android does that too (I mean FC) whenever I open detail message or upload picture from gallery.. I've tried 106, 104 and 100 and still having the same problem.. it's not happening when I use 120 for density, everything seems work properly normal.. is that common or I have to do something to fix that problem?
Thats not normal behaviour for market, although it has been known to be a little flakey on some builds, however this is unlikely to be related to lcd density, since density only affects the visual appearance of the screen, not the OS itself.
Which Panel?2 or 3?
Am using HTC Tytn II and recently i tried almost all Android builds(donut,eclair,froyo) on my device.panel 1 shows some pixel errors and panel 2 and 3 makes no big difference for me, both settings showing a white flash screen on wake up!
and panel 3 i feel little smudge,not sure.panel 2 wake up with white flash screen and follows by grains(just like noisy TV screen).All these for two seconds.after that TYTN II behave normally.Any body can help me please?

As previously stated, panel 2 is the most common of all.
As for the white flash and grainy display, this is due to the fact that we have to "fake v-sync" in order to display anything on our screens. Remember, Android was not designed for our Kaisers, but developers got it to run, piece by little piece, really well on our devices. There will always be drawbacks to this as the hardware doesn't really meet the requirements of what Android was developed for.
If you want to see whats going on when you have a white screen or snow, slide the keyboard open and press "Fn-left softkey". this brings up a screen that shows you what Android is doing.
To return to the main screen, press "Fn-right softkey".
Hope this helps...

[Q] Best resolution for wallpapers

what is the ideal resolution that we should use for the G2, so that the image will be displayed as best as possible? i have a lot of wallpapers on my desktop that i'd like to use that are 1280x____ or higher, so obviously those won't work. thanks

There's an app called Wallpaper Set & Save free on the Market. It does a much better job than the native option. Highly recommend it. I usually use very high resolution images. 1200x____.

I'm gonna have to disagree with the previous posters here - the best resolution for any display, whether phone, computer, or whatever is always the native resolution of the display, and in your case that would be 800x480 pixels.
just take any wallpaper you like that is larger than that and crop it until it is some multiple of that, i.e. the aspect ratio is 5x3 and then resize from there to the 800x480 size.
so, for example, a wallpaper that is say 1200x720 is already the correct aspect ratio and ready to be resized by any imaging program such as irfanview, takes about 5 seconds, and if it's a jpg, then convert to png file first so you don't lose resolution during the resize.
or you could just look in google images for "800x480 wallpaper" and you might get lucky and find one that is already the correct size that you like, and then you are ready to go.

I was just stating my experience. I always use photographs that are very high resolution. I apply them with the application I mentioned previously, and they look sharp. I know nothing more about how or why it works, but it works. Images of lower resolution, for instance 480X800, the native resolution of our device, always appear somewhat blurry. Perhaps you can elaborate on this...

Actually this is correct, because the vast majority of launchers support scrolling wallpapers the wallpaper needs to be larger than the native resolution of the phone.
But if you have wallpaper scrolling disabled or are running a sense 3 rom the best of bet is to use a wallpaper that matches your screens resolution

How to Change The Resolution of Your Phone / A Must if You Have Root!

So it has been mentioned throughout a lot of threads but I figured I would give a step by step and overview for the people who do not know about this or are unsure what it means and does. You must be rooted to use this.
When you compare our phones to a phone that has a qHD display you will see that the qHD display will have smaller text and will allow you to view more on the screen at one time then our WVGA screen allows. Well this is how you can even the playing field and view your phone like it was a qHD or even a 720p screen.
No more super large text like your phone was built for the blind. Also, a great feature if you use an alternate launcher you can set the screen to 5x5 or even 6x6 depending on the resolution you pick.
You will need the 2 apps from below.
First you need to install busybox. Download the app and then open it. From there it will ask you to install. Just choose okay for all the defaults and don't change anything.
https://market.android.com/details?...t=W251bGwsMSwxLDEsInN0ZXJpY3Nvbi5idXN5Ym94Il0.
Next app is lcd resolution. This is where you change the resolution.
https://market.android.com/details?...NvbS53ZW1vYnMuYW5kcm9pZC5sY2RyZXNvbHV0aW9uIl0.
There are 2 settings I use, 200 which is almost identical to qhd. qHD is 960x540 and the app allows you to set it at 960x576. You can also set it at 160 which is 720p. You can use all the settings in-between as well but I stick to these 2. You can do your own testing and see what works best for you. Make sure when testing that you do not click save on boot in case your Rom does not play nice with that resolution. I have found that 200 works almost everything but 160 can be a little more tricky, especially with certain themes. You top bar will be all blurry. A reset will put you back to stock if your Rom does not like the resolution as long as you did not click set on boot.
By doing this hack, TW launcher will not play nice so you must use an alternative. All other launchers will work. The stock dialer will also not work. You can use Go contacts, dialer one or Ex Dialer. They all look and function great. You will also need an alternate calendar and calculator app. Their are a ton to choose from.
When setting your system to 200, you might encounter an error message saying certain apps are not compatible with your phone in the market. This is because this setting while close to qhd is not exactly the same resolution so the market app does not think is is compatible as it is not a standard resolution. There are 2 ways around this. You can install the app through Amazon market as it does not know the resolution you are running on your phone or you can switch back to stock (240) then clear market data and you can download the app. Then switch back to 200. This won't happen with every app as a lot will still download when st to 200.
When running at 160 (720p) you will not have this issue in the market as this is a native resolution of Android and is recognized by every app.
I think that covers it all for now and I cannot imagine going back to a WVGA resolution as it looks sooooooo much better running at a near qhd res.
Below are 2 picks showing the difference. One is stock, one is set to 200 (qhd) and the other to 160 (720p).
Stock (240)
qHD (200)
720p (160)
I like 720p. Also, you can edit your build.prop manually and modify:
ro.sf.lcd_density=240
Does anyone know how to modify a theme to make it work with this?

That works as well but the app makes it much quicker to jump between resolutions then having to edit the file.
When i changed it with LCD density the resolution changed but there was lots of space under the home screen # indicator, can you do a shot of your home screen and wallpaper to see what it looks like?

you can't use Touchwiz. Need another launcher, and dialer. On some roms the camera and music apps break too if you go too low (like 720p), likely others.
I am confused, if the resolution can be improved via software, then how come the manufacturers are not doing it, what is the catch?

I was going to take issue with OP's terminology but decided to not be 'that guy'...
...but here we are.
This doesn't actually change the resolution of the panel at all. You always have the same amount of pixels. Period. All this does is scale the UI. at a screen density of 160 our screen will display things at the size that a 720p screen of identical size would display them. However we lose detail on fonts whereas a 720p screen would have the same amount of detail at 160 as we would at 240....roughly. If you can live with smaller and slightly blocky fonts, go for it.
I can. It's awesome.
another confusing but interesting tidbit: LCD Pixels are made up of red green and blue subpixels. Our panel and the 720p Galaxy Nexus panel have an identical amount of subpixels. But the 720p panel achieves a higher resolution by using less subpixels for each pixel. That is why it is said to have a "pentile" display, as each pixel is composed an arrangement of 5 sub-pixels whereas we have 12 sub-pixels for each pixel. This also explains why 800x480 (WVGA) "pentile" panels look like crap...err...ahem...receive so much criticism. (See: motorola displays)
EDIT: Also, more sub-pixels per pixel means better 'sub-pixel hinting'...which is an effect used to enhance text on LCD panels. The fact that we have so many sub-pixels is probably the only reason why we can pull this off. Of course I'm assuming that android takes advantage of subpixels.
Just a reminder to everyone to nandroid before doing anything like this;
My phone won't boot after doing this. I can get into CWM, but anytime I try to reboot it gets stuck in a loop at the Sprint / 4g animation. I suspect it has something to do with busybox installation but who knows.
I did NOT have the "Set on Boot" selected in the LCD density app. I think I already had busybox support... maybe trying to install the market busybox app borked something.
Anyhoo... always do a nandroid, kids!
As Dan mentioned, it does not actually change the resolution in the true sense but for the purpose of this thread I didn't get into that detail.
I think our screens look 10x better then the Evo 3d and the photon screens when our screens are set to WVGA compared to their qhd display. This only makes it better. With a screen this large it only makes sense to shrink things down to get more on the screen.
Now the Galaxy Nexus screen, I am expecting that to be a killer screen.
Ok thanks, it was leaving like choke real estate under the page number on the screens, I actually like Touchwiz but thanks for the heads up

I think if we could yank touchwiz off of a Galaxy Note it would do 720p (160) and if not whatever the density setting is on the Galaxy Note would make it fit perfectly.
As far as I've seen, touchwiz isn't ingrained in Android at all. I could be wrong, but, it seems like just a launcher. It's nothing like Sense which has it's big fat tentacles way up Android's ass.
...though I'm not a fan of Touchwiz, so, it really doesn't bother me at all. It's not that I hate touchwiz--I was actually astonished to find how nice it was after all of the Sense-o-philes bashed the crap out of it--I just love me some Launcher Pro and/or ADWex, depending on the time of day....though every now and then I throw on Launcher7 for giggles.
I think you are right on all accounts. I actually like its styling (well with ICS + ICS Twist) but the fact that the launcher is hardware accelerated is too much to give up

Has this been verified? I stopped caring about it once I got LP/ADW up and running and it seems supernaturally smooth. Though I have to admit that the transition to the app drawer in TW is phenomenally smooth...aside from that, though, I don't really see it.
...and if only TW is hardware accelerated that must be via an API. Samsung proprietary? Considering the popularity of the SGS2 worldwide I'd imagine there would have to be another launcher that would take advantage of these hooks.
Honestly if we do, in fact, have hardware acceleration (and I believe we do) why wouldn't that be system wide? Once you go into settings you are out of the launcher and if anyone remembers Cupcake or Donut holy crap was that a painful experience for what was at the time super fast 528-800mhz phones (g1/hero and moment).
this is a great find I think, I really like the tight resolution, not too keen on having to change the type of launcher either
Has anyone noticed the jacked up notification on the notification bar?
And too bad there's not a way to make the dialer and home screens fit the screen now!
Thanks for the hint
Tried this at 160 using go launcher on starburst 1.9.8r with the beta ICS theme and it looked great except the status bar was screwed up. Do you think it might be the theme or rom?

Has anyone been able to get any density changer apps working on their Nitro HD? I've tried all of the following, and none seem to work. It's possible there is a problem with my su access, so if anyone HAS gotten any of these to work, please let me know. That at least tells me I definitely have an su problem...

Never mind; my build.prop file was set to read only.
Excuse my ignorance, but what exactly are they for? Does the density changes only the size of text or everything including graphic become bigger/smaller?

For the most part, yes. Decreasing the LCD Density is like increasing your desktop's resolution. Icons and text become smaller, though apps that are written to scale to any resolution will usually appear the same.
Hmmm...I do see some issues with current density, for instance the avatars in Talk don't stretch to fit the square.
So witch tool would you suggest?
I tried DPI Changer the other and couldn't get it to work, thanks for the heads-up about the build.prop!
The Nitro also already has the "Screen Optimization" util (Settings > Display > Screen Optimization) that resizes checked apps to the Nitro's display. It helped with a few games, but some games just won't work (like Asphalt 5)...But now with the Density changer, maybe I'll give it another try.

Actually, I'm not sure any of the tools above would work; part of the problem I am sure is that the build.prop file was not only read only, but there wasn't an entry for the LCD Density - so if the apps work by simply retrieving and editing the property, they aren't going to work. I just edited the file directly with a text editor, saved, and restarted the phone. Some of the apps would then at least report the new value, but still didn't seem to successfully update it. I quit looking because I got the density I wanted (about 270, down from the native 320).
As for compatibility with other apps, if they don't quite look correct it is because they aren't written well, and a different density changing app isn't going to do you any good. Again, it's like changing the resolution on your computer - it doesn't matter how you change your resolution - once it's set it is what it is, and apps that don't accommodate it just aren't going to look good.

The Screen Optimization utility only seems to address apps that are written to a specific resolution - not pixel density. In this sense, the LCD Density is actually more like changing your computer's DPI - I didn't use that analogy first because more people are more familiar with changing a desktop's resolution. The fact is that LCD screens have a set resolution, and you cannot increase or decrease that resolution through software. The Nitro's extremely high resolution (1280x720) just isn't common enough in phones (most software would see it as a tablet) to be accounted for in all apps - particularly older ones. So, the screen optimization app that is built-in will automatically stretch apps to take up the entire 1280x720 pixels, even if the app only renders (for instance) 800x480 pixels .

The attached image shows MobileSheetsPro running on my old Galaxy Note 10.1 (left) and on the S4 (right).
The note is 1280x800 and the S4 is 2560x1600.
I would expect the applications to look the same, but this is not the case. On the S4, the dialog is about 25% larger, the icons are larger, etc.
If you are familiar with MobileSheetsPro you can see that I needed to lower the font sizes used by the program (to about 80%) to get the same contents on the display. Other applications show similar differences.
DevCheck (see 2nd attachment) shows resolution 1280x800 and screen density 160dpi (mdpi), 1280dp x 800dp for the Note, and for the S4 resolution 2560x1600 and screen density 360dpi (xhdpi), 1138dp x 711dp. I find the red numbers puzzling.
Is this normal behaviour? Is MobileSheetsPro misbehaving? Is there some setting that can (needs) be adjusted?
'm confused about this as well. Just picked up a a new s4 for super cheap...and games are too zoomed. I used recheck and an online tool and they both show 1280 x 800. Tried changing min width in developer settings to no avail
My tablet is at home, and this isn't the behavior I remember, but i don't use Mobile Sheets, and it could be specific to software. Android does some weird treatments that are supposed to be based on resolution. The xhdpi is a clue to this. In your old tablet it was using the native resolution in determining what resources to use/scale. On the new one, it appears to behave as if it believes the dPI is higher than it really is and the resolution lower. Somebody who understands better how this works in Android will have to give a more complete answer.
