How to Know if the Video Card Is Working?

A video card, also called a display adapter or graphics card, is a computer device that sends a video signal to a monitor. When you plug a monitor cable into a computer, you are plugging the cable into a video card. Some computers have video cards built into the main board while others have "dedicated" video cards, which are connected to the motherboard using an expansion slot.

Step

Click "Start," right-click "Computer," click "Manage" and then "Device Manager."

Step

Double-click on "Display Adapters." If the video card is installed and working properly it will be listed under "Display Adapters."

Step

Right-click on the card, click "Properties" and then check the "Device Status" box on the "General" tab. If the device is working, the device status box will read, "This device is working properly." If the box says, "This device is disabled," go to Step 4.

Step

Click the "Driver" tab and then click "Enable." The device will be turned on.
