My monitor quit working and says check video cable and video source.

All of a sudden my monitor won't display my MacBook Pro. It says check video cable and video source. I have reconnected all cables. I had to use a usb cable to connect and it was working just fine. The monitor was bought in December 2019 so should not be going out.

Welcome to the HP Support Community!

I reviewed your post and I understand that the monitor is not working on your Mac computer.

Don’t worry, I assure you I will try my best to get this sorted.

Have you tested the monitor on a Windows PC?

HP monitors are not supported in a Mac environment. However, newer Macs use graphics with VESA modes and can display to most HP LCD monitors. To do this, connect the monitor to the Mac while the Mac is off, and then turn on the MAC. The monitor should operate at 60Hz. The INF and software for the HP monitor are for Microsoft Windows and cannot be run in a standard MAC OS environment.

I hope that answers your question and you have a great day!

If you wish to show appreciation for my efforts, mark my post as Accept as Solution. Your feedback counts!

Cheers!

I disconnected my monitor from my Mac and turned off my Mac. Then I connected my monitor to the Mac. I still get the following:

Input Signal not found. Check video cable and video source. 

As to not working with a Mac. It was working just fine since I got it in December. Then just quit one day. So the problem should not be incompatibility with a Mac since it was working fine before. And I do not have a Windows PC available to test it on.

As informed earlier, HP doesn't create any drivers for Mac computers or provide support. I recommend you check with Apple support.

Cheers!
