You may change the screen resolution of your computer for any requirement. Did you change the screen resolution of your Android/Tabled? There is a difference between two of them. If anybody increases the resolution of his computer then the text, icon, app etc become smaller. But after increasing the density of Android/Tabled the icon, text, app etc become larger.

For the Screen Resolution of Android/Tabled the density setting is needed to change. Simply we can say that the DPI (dots per inch) is changed. It is known to all that the default DPI of Android/Tabled varies according to the different devices. For example: 120, 240, 320, 480…

When you decrease the DPI then the text, icon, app, widget etc. become smaller and after increase the DPI these look larger than before. Most of the user wants to change the screen resolution of their Android/Tabled. Because it increases the screen performance of the device. To make enough space in the home screen during the time of playing video games it is needed to increase the resolution. At that time high resolution is needed.

The accurate value of DPI (dots per inch) could not be measured. It depends on your device. The display setting which perfectly fit for your Android/Tabled is the accurate DPI of your device. You may try 2-3 setting. Somebody change the DPI from 120 to 90/100, 240 to 120/180/190, 320 to 240/180. But remember that if you do not set it accurately some app may be crashed. 

How to change density: You can use two processes to change the density of the device.

With app: It is a simply process. We use here the LCD Density Changer app. At first you need to download it. Then install this app in your device. Now change the density value and click the change button. After restarting the device you will see the changed screen. This process is very helpful for the new user. Just remove the battery to get default setting if any problems occurred.

With build.prop edit: It is also a easy process. Just download it from here. Install in your device. Then alter the density value of qemu.sf.lcd_density. Save and restart your device.
