Lenovo ThinkCentre 7638 Video Card
A graphics card processes the input and renders images to the monitor where it is displayed for you. Almost all newer desktops will have at least one spot available for a video card to be installed. There are two types of video cards, integrated and dedicated. An integrated graphic card is built-in to the main board, while dedicated is a separarate piece of hardware that gets installed. At the moment, nVidia rules the dedicated card market, while AMD is in second. Integrated, or onboard, graphics are almost never as good as a separate video card, in general. Dedicated video cards are usually necessary for high-end games on the desktop like Battlefield, Fortnite or Far Cry.
Elements of an inadequate display card
- Your display produces colors that are all wrong
- Your Lenovo reboots when beginning a game
- The display does not come on when starting the computer
- The video card driver has issues installing correctly
