LCD Density is a tweak I like to make due to my eye sight (or lack thereof). There are a few apps that will change this setting for you provided you have root access. The problem I've run into is the dreaded "your device is not compatible" on the Play Store (Android Market). The reason behind this was due to an awkward setting. 2 out of 3 apps I've used in the past had pre-set configurations. Usually the settings to choose from were 240 (default) 260, 280. On the smaller side were 220, 200, and 180. What I found out recently is 256 is the native PPI. So do yourself a favor and find an app that has a sliding scale in increments of 1 PPI and set your Atrix2 to 256 if you'd like a bit larger images and text. Its helped me feel comfortable using my phone and I no longer incur the Play Store (Google please change the name back) error. Otherwise I'd have to readjust the LCD density, reboot, clear data for the Store and THEN go get the app. Then change the density BACK...reboot. you get the idea. It was painful. So to make a short story long, LCD density at 256 for the farsighted people like me. Whew! Didn't mean for that to be so long. Hope it helps.

Hi everyone
So, I have this Android Tablet called the Haipad M701 which runs on Android 2.1
By default the icons and everything are HUGE, doesn't look too good So, I rooted the device and found a density setting which by default was at 240. I changed it to different values between 160 to 240 and with smaller values it looks very nice
BUT at any value other than the default 240, almost ALL apps and games are no longer in fullscreen
Does anybody know if there might be a fix for that?
Thanks
wow... not a reply since sept... not sure if you get it fixed or not.
one step you can try is to turn off the compatibility mode in your tablet.
this should fill up the whole screen in most apps except some apps that written specifically for small screen phone without adding large screen display mode in it.
Hi guys. Lets say I have a game or app and it lags cause of 1080p. (DO NOT answer like: This is not the resolution problem, because sometimes it is). Or just app is not supported by full HD. Anyway. Can I change the resolution for 1280x800 (Popular and from normal Transformer)? Does simply DPI change work? What to set? Please tell me. Just for the situation with 1280x800, I want ALL apps etc to run in this resolution. Will it lag anyway?
Sorry for my English.

Actually this is a pretty good question. Some games can't really be displayed in full HD because it just requires much better hardware than is in our devices. Lowering the resolution would probably be very helpful in improving the frame rate and consequently the game play.

I'd like to know an answer to this too. Is there a simple way to do this, such as installing an app from the Play Store?
perhaps paranoid android can help?

have not tried it myself.
I don't know of any app or setting that does what you want.
changing the dpi will do nothing to change the resolution. all that does is tell the OS the physical size of the pixels on the screen in an attempt to keep UI elements the same size across varying dpi screens.
for example, if you take an icon and display it on a regular screen and an hdpi screen with a straight 1:1 pixel mapping, it will appear much smaller on the hdpi screen. but if you tell the OS what the pixel density of each screen is, it then has a reference point and can then enlarge or shrink the icon so that it appears to be roughly the same physical size on both screens.
this is why lowering the dpi setting on your device shrinks everything. the OS thinks the pixels of the display are much larger than they are and shrinks the images to make them appear the intended size.
to change the display resolution, you'd first need a display driver that supports the lower resolutions, which we seem to have since we can output at 720p over hdmi. then you need a screen that will upscale lower resolutions to fullscreen (because you really don't want to play in a tiny 1280x720 window do you?) when non-native input (something other than 1920x1200) is received. i'm not sure if the display in the infinity is built to do that. they may have designed it thinking they will never run it at anything other than native resolution and left it at that.
who said anything about dpi?
Transformer TF300 update on TF700
Happily we have previous Transformers with almost the same hardware and lower screen resolution. Do I have FULL HD installing this (UP) ? I guess gaming on tablet with lower resolution is not possible, but maybe I can downscale the graphics with CHAINFIRE 3D. This is really cool feature. I think we all need it (now and in future). 1280x800 is acceptable res, and some games just won't work on FULL HD.

The phones keep becoming inferior with every superior model getting launched. Some users might not want to buy a new phone just yet. You might want to get the most out of your device while it lasts. To compensate for the continously increasing screen sizes and resolutions in the newer phones, we can change the Screen Density of our devices in order to utilize our screens more efficiently.
Most manufacturers stick to the standard DPI of 240 on the large screened phones like Samsung Galaxy S II or HTC Desire HD, so it might be too big to really make efficient use of the Android device.
Still, there is hope. Just make sure that you are rooted and equipped with Root Explorer or a free app like ES File Explorer in order to access the Root owned partition of the device.
Method:
1. Open Root Explorer
2. Go to /system
3. Click on Mount RW (It shall appear aa Mount RO)
4. Look for build.prop. Long press on the file and press Open file in Editor
5. Scroll down to ro.sf.lcd_density=240
6. Change the value to anywhere between 180 and 240. The lower the value, the higher density your screen will have.
7. Click on the Menu button , and Save and Exit.
8. Reboot.
You should now have a phone with the same screen size but alot more density, slightly smaller text and more space to use applications on.
This guide can be used on all Android phone, even the smaller MDPI and LDPI phones to make your screen to appear bigger and more useful . However, you will have to tinker with the value unless you find one that suits you best.
If some applications cannot span properly to the new screen size, download Spare Parts from the market, uncheck Compatibility Mode in the options, and reboot.
Some launchers may act wierd , however most do look good with a higher density look!
Do press the Thanks button if this guide has helped!

I am using 160. With this value you don't have problems with play store.

What issues did you experience with play store before?
When I used different values between 160 and 240, i. e. 180 or 200, I had compatibility problems with play store. New program version weren't shown as update, and if I searched for apps the message Not compatible with this device appeared. With 160 no problems with unhacked play store.
Hi,
what is optimal DPI in your opinion, for the OP7 Pro?
And how does variable screen resolution affect DPI set in settings? Times used to be easier when display resollution was fixed at 1080p. Do one needs to disable this autochanges in settings to keep table image size?
I used to have either 390 or 400 DPI set virtually all the time on my Oneplus 3, Oneplus 5 and Oneplus 6T... But with this unnecessarily high resolution that is, absurdly, used only sometimes, I would like to hear your experiences.
Thanks
In OOS, I use the "Small" setting in display which comes to 470dpi
In AOSP, it is probably pretty similar. I basically move the slider in display down one notch. I am not currently on AOSP so I'm not positive what that setting is or the actual dpi value.
So i really like the DPI at 200, it means I can see more than 4 lines of a text message and dont need to scroll for days to get to options in most apps, but having the GW4 on dpi 200 is a mess, the tiles are just shrunk down and attempting to work in the top left quarter of the watch while sometimes elements from them(like weather) will try to centre making things overlap and ruin the visuals.
Is there any way I can have my low DPI without having janky tiles? am I just choosing bad DPI numbers with the ones I have tried and that is what is causing it? Preferably id like to be able to choose the DPI per app but I assume that isnt possible
Let me put it this way. You use android smartphones for some time, right ? At last 8 years, right ? Have ever seen in any android phone dynamically adjusted DPI per app ?
I'm not sure if it's possible to change DPI per app via ADB, but you should be able to decompile each APK and manually set the DPI in Android Studio. It could be a lot of work if you want to customize a lot of apps, but it's an option if it's important to you.

I am not shure if it is move in the right direction. Lets say you rework app to 100 dpi BUT display will still work in 200 dpi. So the visual will be distorted.
This is not Windows where app can set display of the monitor to required resolution.
I don't know per app but you can increase or decrease all on your SW4.
