I ordered an Amazon mini HDMI to HDMI cable; it worked perfectly on the first try--when I wanted to connect my laptop to the TV. After using it, I took it off and switched back to regular TV. Two days later, I wanted to connect my laptop to my TV; but now it's not working. I went to display settings and it does not recognize an additional display source. I'm using windows 10--what do I do? FRUSTRATED.
