How to Check My VGA Card
IBM introduced Video Graphics Array (VGA) as a video standard in 1987, but it is not uncommon to see it on modern desktop and laptop computers. It was the first standard to render clear, high-resolution displays on the computer screen. The VGA connector is usually a part of the "video card" hardware component in PCs, which sends display data to a monitor or LCD screen. Microsoft includes a troubleshooting tool in the Windows 7 operating system that performs a check of the video card adapter, including VGA components.
Click the Windows orb logo at the bottom of the desktop to show the Start menu. Click the "Control Panel" from the menu to open a window.
Type "troubleshooter" in the search box in the top-right corner of the window. Click the "Troubleshooting" link that appears in the center of the window in the search results.
Click "View All" in the left pane of the window.
Click "Display Quality," and Windows will begin checking the computer's video card adapter. Monitor the screen, answer the questions and follow the instructions if a problem and solution are given by Windows.
