What is the purpose to change the Android device screen resolution? Well by change the screen resolution and DPI (Dot Per Inch) / density, there is some purposes like:
- Make a device screen looks bigger or smaller
- Increase performance on the Android device by set smaller resolution or higher screen density, because it means everything on the screen is rendered with lower quality.
- Render more object and graphic on an Android device screen by increasing the screen resolution or reducing the screen density.
- Fix the PPSSPP emulator application "Native device resolution" and "Auto 1:1" graphic rendering that causing black dotted graphical bug on older Android version (older than Android Kitkat). I will tell you more below.
PPSSPP emulator application black dotted screen bug on older Android version is fixed by increasing screen resolution
Yeah, this one is definitely true happen on my Android phone Samsung Galaxy V. But the bug is also came only when I using ROM with Android KitKat. The black dotted screen is not appear when I used ROM with Android 5 Lollipop and higher.
When using PPSSPP emulator application on my Samsung Galaxy V, I do not know why if I render the graphic same as my screen resolution the screen is going blacked. Rendering same as my phone screen resolution is the only option I can get better graphic quality and get better performance and speed at the same time. Because if I render on 2x PSP resolution, the game become very laggy.
Accidentally when I want to change my Samsung Galaxy V phone screen resolution using Nomone Resolution Changer so I can make it "looks" bigger, then I start to play games using PPSSPP emulator surprisedly it can fix the black dotted bug.
How to change Android device screen resolution and density using Nomone Resolution Changer application
Requirements:
- Rooted.
- Backup.
- Install third party launcher and keyboard. It is to anticipate if your stock launcher and keyboard cannot adapt to different screen resolution and DPI, so you can still operate your Android device normally by switching to third party launcher and keyboard.
Just install the Android app Nomone Resolution changer. Open the app and there we can select the screen resolution and DPI template. Or if we know exactly what screen resolution we want that can match our Android device, we can also enter manually the exact screen resolution and DPI settings.
Beware that if the template is not supported by the device System UI, the system will constanly give crash toast message. Do not worry because the Nomone Resolution Changer app is already have prevention step.
After we change the screen resolution it will give 10 seconds dialog are you want to apply the new value for furthermore or not. If we not choose to apply it after 10 second, it will automatically restore to our Android device original resolution and DPI. So, in case things goes wrong, just ignore the dialog and it will restore to original resolutions and DPI settings of our Android device.
If your purpose is to solve the blacked screen bug on PPSSPP native device resolution render display on your Android device, it is enough to increase all the value just a little bit, example 1.1x of original so the device performance is not affected too much because we render the screen on higher resolution.
• Example if your Android device original screen option values are: widht=480, height=800, DPI=240.
• Then the new value should: width=528, height=880 DPI=264(or original).
Above setting is able to solve the blacked screen bug on PPSSPP emulator with native device resolution on my Samsung Galaxy V running Android KitKat.
After every you change your Android device screen resolution and DPI, it is recommended to restart your device to optimize the change.
