Hello, i have a lenovo z575 laptop and up until today i could use it on my tv via hdmi cables. Now the laptop wont recognize the tv. I called lenovo support and they said that even though i have a software and hard ware warrenty this specific problem isnt covered because its a setting. They wont tell me what the setting is unless i pay them 250$ and i think thats absurd, so i was wondering if someone could help me. I have restarted the computer multiple times, tested the hdmi cable, tested the hdmi port on the tv, tested all ports on the laptop including usb, and vga. Please help me.
