No signal being sent to monitor or tv

Hp omen 870-213w
Microsoft Windows 10 (64-bit)
Just purchased an HP omen 870-213w and it won't send a signal to a monitor or two different tvs. Any help will be appreciated.

No signal being sent to monitor or tv


Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out!


As I understand you are getting the message - "monitor input signal not found",

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

Does the message appear on an alternate monitor?

Did you reduce the resolution of the monitor and check if it works?


While you respond to that, I recommend you check with another monitor and if the issue doesn't occur on the other monitor, follow the below steps:


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


(By the end of this article all the issues should be resolved)


Keep me posted,

If the information I've provided was helpful, 

give us some reinforcement by clicking the solution and kudos buttons, 

that'll help us and others see that we've got the answers!

Good Luck.
