I clicked on the graphics accelerator icon in my task bar, went to properties, and changed the settings on the display to "clone". It worked. I'm not much on computers and fixing them but as of right now it worked. I was watching Netflix fo about a week and al the sudden i started getting "no signal" on TV I tried eveything. This was very simple to do because I did it. lol. My laptop has " Intel R Graphics Media Accelerator Driver for Mobile" That's what I right clicked on then made the change.Hope this helps and I hope it fixed my problem.
