Hi All,
I currently own a viewsonic vpad 10s tablet. It's currently on 1024x600.. is it possible to have a software hack or other to change the resolution to 1280x like the xoom?
The short answer is no.
The longer answer is...kind of.

OK, and now the even longer answer.
There is no way to increase the resolution to 1280 x 800. Our display is an AU OPTRONICS B101AW06. Look it up on the net & you'll find max resolution is 1024 x 600. What BK553 is speaking about is a change in text DPI. You can see this in Windows where you can change the DPI. Manufacturers normally set the DPI to give the user the best readability but not necessarily the highest DPI. If you change the DPI, text & icons will become smaller (or larger depending on if you increase or decrease the DPI). To see what effect LCDDensity Changer may have, see the attached picture. Icons are smaller & text is smaller, giving the illusion of higher resolution. Notice how the backbround is the same while the text & icons are smaller.
Again, you can not change the resolution...videos, pictures etc will always displayed at a max resolution of 1024 x 600.
By the way, check this post http://forum.xda-developers.com/showthread.php?t=864338&highlight=lcd and you will see that atleast in Dec 2010 there used to be a field in build.prop that you could change to change the DPI. I looked for it in mine (I'm running Calkulin+Clemsyn Combo v6) and that field no longer appears.

I use blade and spare parts to tweak the dpi. don't think you can get up to 1280 with any software though.

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?
Can someone in the states try installing the nest thermostat app on their streak
https://play.google.com/store/apps/details?id=com.nestlabs.android
I can't download it in the U.K. I have tried market enabler and other tricks but I am wondering if it is just the Streak's resolution that is stopping it. There is a review saying it works on the note, so I'm hopeful.
If anyone wants to send me the apk it would most appreciated
Thanks,
Mark
**** Ignore this, found a way of downloading the app and it doesn't support the streak's resolution :-( ******
What do you have the dpi of your Streak set to?

No idea, just the standard resolution.
From Nest
To use the Nest Mobile app for Android, you’ll need:
An Internet-connected Android smartphone (Android 2.2 “Froyo” or later required) with one of the following screen widths:
520 pixels on a HIGH density device.
480 pixels on a HIGH density device.
360 pixels on a MEDIUM density device.
320 pixels on a MEDIUM density device.
270 pixels on a LOW density device.
240 pixels on a LOW density device.
working on GS3
hmmmm, under the impression the GS3 is 720 pixel width, yet the app opens on my device.
just checked their site, same android requirements, and they also mention it should show a popup window if it doesn't meet the requirements.
However, I never got the popup window, so it works with 720?
Looking into Nest, just sent them an email questioning just these items.
Well according to the market, my S5 at 240 dpi is compatable.
The S5 is a standard WVGA (480x800) device, and nearly all devices of it's age are the same thing.
I tried to raise the dpi on my mediapad while running cyanogemod by after_silence but if i enter anything above 213 it removes the home and back buttons and changes to the phone style notification bar. Any Ideas? His Rom is great, Its every thing i want except I want to use my 1280x800 screen as 1280x800. I would post this question in his devlopment thread but xda wont allow my account to do this since i dont have enough posts.
You need to lower the dpi to simulate a larger screen dpi.
Basically if the resolution is equal, smaller screen would have bigger dpi than bigger screen.
Android still use the full resolution regardless of the dpi. The dpi is an indicator of how big your screen is and it will choose the appropriate icon, font, etc based on that. You don't loose sharpness just because the font look bigger.
As the previous poster said - Android will use the full screen resolution no matter what.
When you raise the DPI, you are telling the OS that there are more dots per inch. The number of dots on the screen is fixed, so raising the DPI is telling the OS the screen has those dots squeezed into a smaller space.
At the default DPI of about 213, you are telling the OS that your 1280 x 800 screen is 7 inches diagonal (small tablet). Note that in Jellybean and higher, a 7" tablet will trigger the "small tablet" interface that looks like a Galaxy Nexus phone layout but still has tablet elements.
On the MediaPad stock ICS ROMs, the "high resolution" mode reports a DPI of 160, which tells the OS that your 1280 x 800 screen is about 9.3" (larger tablet).
If you raise the DPI even higher, let's say to 300, then you are telling the OS your 1280 x 800 screen is 5" diagonal (very small tablet / very large phone, like the Galaxy Note). In ICS this will pop you into the phone interface.
The OS uses this information to scale fonts and user elements. So if an app decides it wants to output text on the screen that is 0.5 inches tall:
- At 213 DPI the text will be 107 pixels tall
- At 160 DPI the text will be 80 pixels tall
- At 300 DPI the text will be 150 pixels tall.

Hello,
just edit your build.prop (/system/build.prop) with appropriate rights (e. g. root explorer):
change
Code:
ro.sf.lcd_density=213
to
Code:
#ro.sf.lcd_density=213
Best regards,

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..
I have just bought 10.8 version and I like it, but was really surprised to find out there is no way to change resolution like for example in this video (I am not allowed to post links, but you can search it on youtube under the name: How to Change Screen Resolution in HUAWEI P20)
Is that a bug of some kind and we may hope that this feature will be introduced in some later EMUI updates?
With developer options enabled you can set a custom DPI, effectively changing your resolution
This method doesn't actually change resolution, just the size of the icons, text etc. You can try and check it yourself with some app like CPU-Z for example.
The only option I found is using ADB commands like "wm size 1200x1920" and "wm density 209". This does truly change resolution and sets appropriate DPI for this resolution at 10.8 display size. Needless to say that this method is cumbersome and besides that DPI value has to be reapplied after each reboot, otherwise it resets and homescreen looks messed up.
But yes, when set correctly to 1200x1920 and 209 DPI it looks good and what's more important games run a lot faster.
So why would Huawei remove the option (which is already present in EMUI 8) to easily change resolution specifically for our device is beyond my understanding.
And here is reply from Huawei support:
Thank you for contacting Huawei. We widely appreciate your preference and we thank you for your email.
Regarding to what you kindly shared to us, we appreciate that you point out this issue, we kindly inform you that your screen resolution is unable to be modified unless it is done through a third party application. Due to this, we have forwarded your request to our Research and Development department. Receiving your feedback and inquiries means a lot to our company, since our only way to improve is through acknowledging our customer's experiences.
Yeah it doesn't change the resolution but your command shouldn't either because the same amount of pixels is used. Changing the resolution is basically only possible with amoleds (which we don't have) because single pixels can be disabled.
So that's probably the reason why the huawei p20 has it and we don't. As for what you are doing it should be the same as changing dpi. Grouping small physical pixels to one bigger virtual pixel, decreasing the amount of different content the tablet has to render and therefor making the tablet run faster.
I was able to set my screen res to something else using a third party app on my note 2 (amoled) but not anymore on the LG g5 (ips LCD)
Hope what I'm trying to say is understandable.

Hehe, my honest answer is not quite. But I would appreciate if you could tell me which DPI should I set in Developer Options to get the same effect as I am getting with "wm size 1200x1920" and "wm density 209" in terms of speed gain and homescreen look (not distorted or messed up, etc).
Edit: Tried changing DPI only without changing resolution today. Result: no speed gain in any games I played.
I'm using this app to change resolution and dpi.

It required root access (I'm using magisk). But author said that it just need adb access for those don't have root. Works brilliantlu on my M5 8.4.

As far as I undertand to avoid distortion for your 8.4in it should be something like 1920x1200 and 270 DPI.
Though again, as far as I understood, you can play with DPI as much as you like, it doesn't influence game speed or battery drain like resolution does.

Thanks, I am going to check out this app. The problem is that I don't want to root my M5 in order not to void the warranty. So going to try the ADB way and hope permissions will not reset after reboot.

After you've lowered your resolution from stock 2560x1600, do you find better battery life?
EDIT: Also if I want to change it back to normal, do I jsut change the resolution back to 2560x1600 and 359 dpi?

I have not been using this tablet long enough to notice major difference in battery drain from changing resolution. I was mostly interested in speed gain in games. But from the fact that there is an option in Settings menu to automatically lower resolution to save battery, I conclude that there must me some (albeit a small) advantage in overall power consumption when using lower resolution.
And yes, to get back your native resolution and DPI, I guess you can either use ADB commands "wm size reset" and "wm density reset", or just set 2560x1600 if you are doing it through an app. As for DPI, it depends on which display settings you use in the Settings menu (large, small, etc.) but the default (factory) one seems to be 480. All this Resolution-DPI stuff seems to be very confusing as for me.
