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.
Click "Start," right-click "Computer," click "Manage" and then "Device Manager."
Double-click on "Display Adapters." If the video card is installed and working properly it will be listed under "Display Adapters."
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.
Click the "Driver" tab and then click "Enable." The device will be turned on.
Tips & Warnings
- If a video card is not working properly, you may experience display errors.
- Right-click any device in the device manager and then click "Update driver software" to make the system search for new drivers. A device will not function without drivers even if it is enabled.
