A VGA driver facilitates communication between the operating system and the graphics hardware, specifically for devices using the Video Graphics Array (VGA) standard. It translates high-level graphics commands into a format that the VGA hardware can understand, enabling the display of images, text, and graphics on the screen. Additionally, the driver manages various settings like screen resolution and color depth, ensuring compatibility and optimal performance of the graphics output.
VGA is an interface for connecting a monitor (as well as a specific resolution used in the earliest cards and monitors to implement it). AGP is a bus on which a graphics card can be installed.
The Video Graphics Adapter (VGA) was one of the first standards for video cards so that manufacturers could create increasingly powerful video cards that would be used in a variety of computer systems. VGA also represents the 680x480 resolution that was standard on VGA-compatible monitors.
VGA stands for Video Graphics Array, a display standard introduced by IBM in 1987. It defines the resolution and color depth for computer graphics, originally supporting a resolution of 640x480 pixels with a palette of 256 colors. VGA has become a widely used interface for connecting monitors and projectors to computers, although it has been largely supplanted by more advanced standards like HDMI and DisplayPort in modern technology.

The full form of VGA is Video Graphics Array. It is a display standard introduced by IBM in 1987, primarily used for computer monitors. VGA supports a resolution of 640x480 pixels and a color depth of 16 colors, though it has been succeeded by more advanced graphics standards over the years. VGA connectors are still commonly found on many devices today, primarily for backward compatibility.
HDMI and VGA are both video interfaces capable of carrying computer display data to a monitor. HDMI is digital, VGA is analog. HDMI is NOT inherently better than VGA. Each will support a wide range of screen resolutions and it is the screen resolution and color depth that affect the image quality rather than the interface used. Choose a graphics card that supports the resolution you need and make sure it has the output you need to connect to your monitor.

What are your system specs? What type of graphics card do you have (Nvidia, ATI).
640x480
WVGA stands for Wide Video Graphics Array, or Wide VGA. It is basically any display resolution with the same 480px height as Standard VGA, but wider.It is commonly used in hand-held devices or laptops.
VGA (Video Graphics Array) supports up to 640 x 480, which is a 4:3 ratio between horizontal pixels and vertical pixels. Page 328, CompTIA A+ Guide to Hardware Managing, Maintaining, and Troubleshooting, Fourth Ed.
