Hi, I have a HP Pavillion g7 Notebook. I have often connected my laptop to a tv via a hdmi cable to watch streamed movies, etc. My laptop recognized the connection automatically, I never had to adjust any settings on my laptop or tv besides selecting the correct hdmi channel on the television. I just bought a new Insignia 32" - LED - 1080p - 60Hz - HDTV Model: NS-32E440A13. I also purchased a new Rocketfish HDMI cable. When I got home, set up the TV, and connected my laptop via the cable. The tv showed a black screen and a "NO SIGNAL" error. I tried it for all 3 hdmi slots- no change. I then cycled through all the different projector modes, and still nothing. I tried going into control panel- hardware and sound- display- connect to an external display. When I click on "Detect," my laptop does not recognize that it is connected to the tv. I've tried rebooting, turning both devices off, unplugging the cable, removing the power from the tv, plugging back in the power to the tv, attaching the hdmi to the tv then the laptop, then turning on tv, then turning on the laptop, and many variations of these and still nothing. I tested the hdmi cable on my dvd player, and it worked fine. I also tried connecting my laptop to 2 other televisions (Panasonic and a Vizio) using other hdmi cables, and still got the "No Signal" error. No problems show up in the Device Manager. I wondered if a recent update or program I installed might have caused the problem, but when I attempted to do a system restore several times, I kept getting an error message that the restore had failed. Any ideas?
