Does your PC turn out but there's nothing on the display? This could indicate a problem with your wires, CPU, power supply, or drivers. Here's what to do if your computer turns on but there's no display.

Quick Ways to Fix Black Display on a PC

If your Windows computer boots up but doesn't display anything on the screen, check for damaged or loose wires. For a dedicated graphics card, plug the cable into the HDMI or DisplayPort on the GPU itself, not the motherboard. You can also reset your graphics driver using Windows + Ctrl + Shift + B.
