Up to a few days ago. My notebook Envy connecting to tv with hdmi. Now I get no signal. All updates are current. I plug hdmi into both my tv hdmi ports and received the same message. My cable box connection is hdmi and works on both my tv hdmi ports. I followed the suggestions in hp help for hdmi, screen resolution is set to recommended and didn't resolve issue. I was able to successfully connect to another tv that is older. I've done everything I know what to do. Your help is appreciated.
