[Q] Is LCD Density safe? - XPERIA X10 Q&A, Help & Troubleshooting

Just now i installed LCD density changer and i have set it to 190.
Is the 190 setting safe and the main thing , is this software safe and future proof that it wont effect my hardware in future.
Thanks.

I'm quite sure you have nothing to be worried about.

you have to worry about your eyes though
190 is to much for me, but loving 220

LCD Density works on software level, not hardware level. The hardware display frame buffer is still 480x854, but when you change the lcd density, the software frame buffer is resized accordingly.
If you decrease the LCD density properties (dunno why increasing the value make things bigger), the SW frame buffer resolution will be increased in width and height, then after the OS finished with the rendering of SW frame buffer, this frame buffer will be resized to match the HW frame buffer, then the content will be copied.
So its safe, but increasing too much will make the phone slower because of bigger SW frame buffer, but of course you can see more text because the text is smaller.

Anyone care to post screenshots with 220 density?
Everything looks OK?

Rooted Nook Tablet Options

Indirect deserves a salute for rooting the NT
http://forum.xda-developers.com/showthread.php?t=1354487
Still running a Nook Color with a dpi of 240 in build.prop, I would very much
get any reports on the following
1. Can the same be done on the NT without too many side affects?
2. Has anyone installed skype and tested the built in Mic?
How about a response as to a rooted Nook Tablet with a higher (240) dpi setting?
speaking completely out of curiosity, how can you display a higher dpi onscreen (if I'm understanding what you're asking), if the display is only capable of 169 dpi?
maybe I'm oversimplifying the question and am not understanding you.

after doing some searching, are you referring to actual font size?
Android allows different dp settings independent of the hardware dpi for UI design. Details in below link,
http://developer.android.com/guide/practices/screens_support.html
Density-independent pixel (dp)
A virtual pixel unit that you should use when defining UI layout, to express layout dimensions or position in a density-independent way.
The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, which is the baseline density assumed by the system for a "medium" density screen. At runtime, the system transparently handles any scaling of the dp units, as necessary, based on the actual density of the screen in use. The conversion of dp units to screen pixels is simple: px = dp * (dpi / 160). For example, on a 240 dpi screen, 1 dp equals 1.5 physical pixels. You should always use dp units when defining your application's UI, to ensure proper display of your UI on screens with different densities.

I understand the advantage to a developer laying out UI that needs to run on different display resolutions, but I don't see an advantage for an end-user. Why would you set your dpi to 240 if you can only display 169 dpi on the device? Won't the tablet simply downsize bit-mapped images when they're actually displayed?
Honest question--I'm probably not understanding something here--and I'm certainly not trying to rile anyone. Thanks!
Per above equation, setting your device's dpi setting to 240 would allow the app to be 150% in size. This aids in legibility, at cost of more screen space.
If you have an NC, you can see this firsthand by adjusting abovesaid dpi setting in build.prop up or down.

Ah, cool. Thanks for the info!
All I wanted to know was if the build.prop can be edited on a rooted NT as I have done on the NC.
Also, I will try once more. Did anyone use the Microphone with skype or some other chat app?

[Q] Android DPI

Can someone please explain how the android DPI system works?
If i reduce my dpi on my Gnex, from 320 to 250, everything gets smaller; it gets denser (as there is more in a smaller space), however the name (dots per inch) would suggest that a higher figure would result in a more dense screen.

There is plenty to read... but you might just take a look at figure 4. which explains sizes of xhdpi, hdpi, mdpi and ldpi drawables.
It's basicly hidger dpi = higher res drawable = takes more space on your screen.

[Q] Decrease Resolution for Gaming?

Hello Tablet Z community,
This is my first post in this devices forums since getting mine last week. It's a great device, love it, etc.
I've never owned an Android device with a screen resolution this high so I've yet to encounter this problem - some of my games (specifically the emulator PPSSPP) have relatively low framerates (compared to my less powerful Samsung P6810 @ 800x1280). I know with computers in particular it's trivially easy to change resolutions in games/the OS, especially to increase FPS but I've never seen a method to do this on Android and Google searches turn up people mentioning device resolution without changing them.
Does anyone know if it's possible to, ideally, force a different resolution for a particular application? A less than ideal solution would be a system wide change but I would be willing to endure temporarily to increase FPS.
Any advice and suggestions would be greatly appreciated
I would be interested to know about this, iv just loaded ppsspp however havent been able to play any of the playable games listed, I did see a few videos of the xperia z playing well, however that has the same resolution and specs.

This is very different, setting the DPI to a non-stock value just resizes the userspace, the resolution is fixed and unchangeable as the OP is thinking. Compared to a Windows PC where you can change the resolution, in Android you only have the ability to change the dpi, which states how large the pixel-to-screen size is. A smaller number indicates a smaller pixel-to-screen size, meaning the information shown on screen is sized for a laeger screen (making it smaller, since the screen is a fixed size). And a larger number has the reverse effect. Android UI guidelines set the optimal dpi for resolution vs. screen size, to mainain a similar experience across devices (similarly sized icons and fonts, etc). Again, this has nothing to do with adjusting the physical resolution of the device, which (to my knowledge) is not possible in Android.

Heh. Thanks for the schooling, but it was unnecessary, I didn't just fall off a turnip truck.
Thanks for the replies guys, at least now I know for sure..

[WARNING] Changing LCD density and then resolution

I just thought I would give everyone a warning about changing LCD density with "adb shell wm density XXX"
(only applies to us non-rooted users -- rooted users can edit build.prop on the fly)
If you change the density, and then decide to check out the other resolutions like 720p and 1080p, it will fully erase your set density and return to stock resolution, even if you change the resolution back to stock (WQHD)
I myself didnt know this. I thought it would keep the resolution and recalculate the density, or reduce / increase the density based on the difference between WQHD. This is not the case.
So for those who set a custom density, DONT CHANGE RESOLUTION!

Is it possible to change the rendering resolution of the Xperia Z Ultra to 720p?

I was wondering if it was possible to change the rendering resolution of the phone from 1080p down to 720p? But I still want to retain the scaling of things. The reason I want to scale it down is because I'm fine with 720p if it means I can push the processor to perform better on games (because it's rendering fewer pixels) and to save battery (smaller screen resolution would mean less stress on the processor = more battery saved).
Just to clarify, I'm not looking to change the DPI, I can use the App Settings xposed module for that. What I want is to lower the rendered resolution so that the processor doesn't have to spend more resources in displaying things.
