Can't see 3rd monitor anymore

My TV has worked fine (Sharp Aquos) as a 3rd monitor for a few years now, even after upgrading to Win10. Every once in a while lightining will strike nearby and all 3 monitors will temporarily shut off and return but recently, the TV monitor did not. I use a professional grade power backup so none of my equipment ever gets fried but when lightning strikes, somehow stuff in the air (I guess) causes my monitors to go out. After this strike, the TV still works just fine and nothing else is out of whack. I have tried everything I can find online, trying to get Windows to detect the TV, but nothing works. All of my drivers are up to date as well as my Windows operating system. I'm really frustrated and it does not make any sense that it should not be working. Any ideas? I am using a 980ti graphics card.

So it's not showing up at all in the Windows display settings or DisplayFusion Monitor Configuration window?

No, it does not show up in either the NVIDIA control panel, Windows 10 or DisplayFusion - but it works perfectly as a TV and for cable. This is all of a sudden and doesn't make any sense.

Super strange! If it's not showing up at all, my only guesses would be one of the following 3 things:
  • The video cable is bad
  • That particular input is somehow broken on the TV
  • That particular port on the video card is somehow broken

Other than that, I'd be stumped too :(

Okay thanks! I am checking the cable itself now because other cables have worked on that same input.

Okay, it was the cable. Very strange. It is not an old cable at all but somehow lightning down the street rendered it useless without damaging anything else.

Strange indeed! At least it was a cheap fix

Well, I'm in Florida so, the number of lightning strikes and the amount of times my monitors have shut down and back on immediately following one, may give an idea of the amount of stress on the cables themselves. Other than that, I haven't a clue.
