HDMI port stop working

[FernandoRS]

Hello everyone, I have had installed a second big screen to my notebook, was working perfectly for weeks, and today for no reason the screen lost connection with my computer, I have tried another screen and new HDMI cable and didn't worked out....

just to make sure I tested the screen on my son's notebook and it worked....so definitely the problem is my HDMI port.....oh yes and also I've tried restart computer few times.... and tried the settings but it doesnt show any link between my computer and screen.

My question:  

Could there be some setting or configuration I missed, or do i really need to take it for repair service?

thanks

HDMI is powered, so when connecting or disconnecting HDMI cable, at least one of two devices must be powered off or there is a risk of a short circuit.
