Greetings .. I have a samsung LED series 8 tv connected to a samsung laptop .. I have been able to watch movies online on the tv connected to this laptop via hdmi for months. But last nite when I turned on tv and laptop the tv shows hdmi source no signal. I didnt change anything. So I troubleshoot by changing to different hdmi port on tv and select the right source .. Same issue. Then I changed to a new hdmi cable. Same issue. We reset the tv same issue. Then I took the same laptop and connected a different tv it works .. so it confirmed tat it is not my laptop or cable problem. Need some prof tips here. Thx in advance
