I can not get my Lenovo computer to connect via HDMI to my 42 inch Vizio TV. I know the output I'm using on the TV works because it connects to my PS3 fine. I know the HDMI cable works because I also use it for the PS3, So I think it is a problem with my Lenovo laptop. The TV screen says "No Signal" and I have gone to Display/Screen Resolution to try and display on my TV. The resolution of my laptop is 1366x768 and my TV is 1920x1080....is this making a difference? How can I fix this problem.
