I don't think there is anything you can do. When you first pluged the HDMI cable in when you first bought your monitor or your card and decided to go with HDMI. What did you have to do then to make it work?
Maybe if you follow those steps you might be able to get it to work again. If your card is dead then you would not get anything to your monitor and if your monitor is dead then the VGA cable would not work as well.
It might be something burned out on the HDMI or the HDMI cable went bad. With out anything to test it with not to much you can do about it for now. Just use the VGA untill you can figure things out and I wish you good luck on this.
could you check the graphic card with the vga or dvi output on another monitor to see if you go signal from the card also do the same with the monitor
The VGA on this monitor and the card on my PC is working without issue.
The problem is that when I use teh HDMI cable, like I used to do, I have 'no signal'. So, either the HDMI on the card or the HDMI on the monitor is hosed.
Does your monitor or card have DVI?
YES! Which leads me to my next question. If I get the right adapters to go from HDMI to DVI, could I not check this card and this monitor as follows:
Plug the HDMI directly into the video card, adapt the other end to plug into the DVI on the monitor...if it works, then the card is good.
Then, the apapter on the HDMI cable plugged into the video card....the other plugged directly into the HDMI...if it works, then the monitor is good.
I could cheaply buy adapters and DVI cables in case it all failed. I know the DVI OUT on the video card is good, because I have an adapter for it to VGA.
It could have burnd out on both ends. Did anything happen that night to make you think that it could have been the storm? Something happened. But the only way for sure to tell.
You will have to take your GPU or your monitor and have it tested or get another card or you have a friend that can help you out a little or take it into the shop.
Because after doing all that you can to get the card to work in the HDMI mode and swaping everything out and wiring it all different ways and you get nothing. Or you replace one thing at a time.
I am out of ideas about what is going on in your case. Look on the good side of this it could have burned out your GPU and Monitor all the way and You would have nothing. I hope you get a fix and I wish you the best of luck. Cheers
