Yesterday I decided to hook up an HDMI cable between my TV and desktop and it worked perfectly fine. Now just after working good for only one night, today it won't work. I plug in the HDMI cable and it does read the intro "Starting Windows" but then then it goes black and says "No Video". What's the diagnosis because I can't figure it out. I tried changing the resolution on my desktop but it doesn't work. It should not work either because it worked fine yesterday. Thanks if you can help.
