Hi@Ivan61, Welcome to the HP Support Community!

As I understand you have the message - No input signal found,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you check if the resolution is too high for the monitor? did you try reducing the resolution and check if it works?

Does it work with an alternate monitor?

While you respond to that, here's what you need to do:

Messages display on the monitor when the computer starts, shuts down or enters suspend mode. Some messages that can display are:

• Going to Sleep
• No input signal
• No signal detected
• Signal Out of Range
• Sync Out of Range
• Cable disconnected
• Check cable connection
• Warning-PC entering power save mode

  ... or similar.

These messages are normal when the computer truly goes into sleep mode or loses the video signal (such as when the computer is turned off). However, if the monitor displays any of these messages when the computer should be displaying video, something is wrong.

If you suspect the monitor should be displaying an image from the PC instead of the message, use one of the following sections that match how the monitor behaves after the computer is powered on:

• Windows opens, but after a while the monitor displays the message

• Startup screens display, but the message opens before the Windows desktop opens

• The message is the only item that displays on the screen
