This is the core device in the graphics card that actually carries out the computational tasks necessary to produce the video you see on your screen. Laptop displays can be replaced, but it’s usually best to let an IT expert handle the process. If it’s a laptop display, then replacement is more involved. If it’s an external display, then you just need a new monitor, and you’re good to go. If you do, then you understand the issue. Plug in an external display (can be a computer monitor or a TV) and see if you get anything. Most laptops are capable of outputting video information.
This is even a good test if you’re using a laptop. It’s entirely possible that the display itself is the issue.Īs you read above, the easiest way to test this is to use a different display. It actually changes the signal, which means your converter usually comes with a boxy component. If your plug on the computer is HDMI or DisplayPort, you can’t just use a simple adapter to make that work with a VGA or DVI.Ī converter is more than just the plug adapter. If you’re going from a digital output to an analog display, you need a converter and not an adapter. It’s pretty common to use adapters to make different displays and computers work together, but adapters don’t always work the way you might intend them to. There’s one other thing to understand about display connectors. If switching displays fixes the problem, then that rules out the connection, and you can move on to the next selection. If switching cables solves the problem, then you know what it was. If that doesn’t resolve the problem, try testing the setup with a different cable and/or a different display if you can. If a plug is damaged, or if the connection is loose, then that’s all it takes to keep your screen dark, even though everything else is working just fine. The first and easiest thing to check is the connection from the computer to the display (assuming it’s not a built-in laptop display). Let’s go over the most common scenarios together, and you’ll get a better sense of what might be wrong, how you can identify the issue, and what you can do about it.

There are also tons of potential software issues that might be the source of the problem. This includes the graphics card, but it’s possible your graphics card is actually just fine. It could be tied to connectors between the computer and the display.Īny of the major hardware components of the computer could be failing. In reality, there are a number of potential problems here. 2 Laptop Fan Loud All of a Sudden? What Could Be Wrong if Your Graphics Card Is Spinning, but There Is No Display? (8 Causes)
