VGA vs. QVGA: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 28, 2024
VGA (Video Graphics Array) is a display resolution of 640x480 pixels, while QVGA (Quarter VGA) has a resolution of 320x240 pixels, a quarter of VGA's resolution.
Key Differences
VGA, or Video Graphics Array, is a standard for display resolution introduced in the late 1980s, offering 640x480 pixels resolution. QVGA, standing for Quarter VGA, has a quarter of VGA's resolution, which is 320x240 pixels, resulting in a lower display quality compared to VGA.
VGA was once a high standard in computer graphics, commonly used in computer monitors and video cards. In contrast, QVGA is often found in smaller devices like mobile phones and handheld game consoles due to its lower resolution.
In terms of image clarity and detail, VGA provides better quality due to its higher pixel count. On the other hand, QVGA, with fewer pixels, offers lesser detail and is more suitable for smaller screens where high resolution is not as critical.
VGA's higher resolution requires more processing power and memory for graphics rendering compared to QVGA. Consequently, QVGA is more commonly used in devices with limited processing capabilities.
The aspect ratio for both VGA and QVGA is 4:3, maintaining the same proportional dimensions, but with VGA offering a clearer and more detailed image due to its higher pixel count.
