The Computer Turns on But no Display on the Monitor

When your computer starts up, but you don’t see anything on your monitor, it can be a bit frustrating. This situation is often called a “computer turns on but no display” issue and this might be due to an Input Signal Not Found HP monitor. There are a few reasons why this might happen, and some things you can try to fix.

  • Check the Connections: Sometimes, the cables connecting your monitor to the computer might be loose or not plugged in correctly.
