Having equipped with a fast display rate, rich colors, and high resolution of 640*480, VGA is widely used in various types of color displays and is mostly used in desktop applications. They have more processing power and need more power.
What is QVGA?

Created shortly after Vga, They are most commonly used for mobile displays and also for the videos captured by mobiles. It is smaller and just a quarter the size of VGA, and hence the name is Quater VGA.
Main Differences Between VGA and QVGA
The full form of VGA is Video Graphics Array, whereas the full form of QVGA is Quater VGA.
Conclusion
Both these video transmission standards are widely used in the world. They both have several advantages and disadvantages, as can be seen above. They both are developed in order to produce good quality images and pictures which can be used in bigger as well as smaller screens.
