TV's HDMI won't work with 3 different computers, but it will work with an Xbox?

I use my tv as a monitor for my PC. I have it hooked up via hdmi. It started storming so I unplugged both my pc and tv yesterday. I plugged everything up after the storm and the tv quit working with my pc it says "no signal". I've tried to hook up my 2 laptops via hdmi and they won't work either. I tried my little brothers xbox and it works. I'm stumped. How can I fix this issue? I want it to work with my pc.

different pc output devices use different codecs to output video. if your stuff does not work on that tv, it is not a compatible tv unless you can find a pc option somewhere deep within its' menus

But it was working 2 days ago. Like I said it was working fine I unplugged everything, now the hdmi doesn't work for any computer.
