HP Pavilion - 15-cs3087tx

I have a HP Pavilion laptop 15 that has been having issues connecting to a HP monitor. I am using a HDMI cable. 

I have done the following:

Used different HDMI cables

Ensured BIOS, all latest windows updates and HP drivers are up to date

I have connected another Dell laptop to the monitor with the same HDMI cable and no issue it works every time

I have cleaned the port with a cloth

I have done a hard reset with the power button on the laptop

The monitor keeps saying check your cable or video source .. input signal not found 

I thought may be if i update to windows 11 from windows 10 that might help.. but no.

 

I could always go to an IT shop and get it diagnosed.. but should i really have to do that?

 

Any help appreciated

Steve
