Hello i have a lenovo ideapad y550 and i am trying to connect it with my samsung tv via hdmi. in the past the connection was successful but lately it can't be done. I've tried several hdmi cables so I believe that is something wrong with the laptop. when I am doing the connection my tv says that there is no signal. In the device manager i can't find hdmi port. I've tried to reinstall nvidia drivers but nothing, I went into BIOS but i can't find hdmi port neither. What should I do? Please help me thank you!!!
