What is it?
A video card, also known as a graphics or display card, is the output device that sends a signal from your computer to your monitor. The device is inside the computer and generates images and translates them into what you see on your display screen.
Types of Video Cards
Most modern day video cards come in two types of video slots: PCI Express or AGP. PCI Express (Peripheral Component Interconnect-Express) cards have been the standard video cards in PCs since 2005. Most computers are equipped to fit the largest size, 16x slot.
AGP (Accelerated Graphics Port) are the more outdated video card slots. They dominated in the 1990s and early 2000s, and usually were fitted in 4x or 8x slots.
Types of Ports
Video cards fit four types of ports on your monitors: VGA, DVI, HDMI, or display port.
- VGA (Video Graphics Array)
- DVI (Digital Visual Interface)
- HDMI (High-Definition Multimedia Interface)
Other Features to Consider
Random Access Memory (RAM): The more ram the higher video resolution you’ll receive. Video cards range from 64MB to 512MB of RAM.
Maximum Resolution: the higher the video resolution a card can display, the more your monitor can display.
Multiple monitors: some video cards come with the capability to support video display on several monitors.
