Hello, I have a Sony VPCF11J0E laptop and have replaced my aging CRT TV with a LG32CS460 Flat Screen TV. When linking via HDMI cable the input screen on the TV states ‘no signal’. My son’s Hitachi Laptop worked first time and displays his laptop monitor on the TV. I have checked the Sony manual and tried the duplicate, extend, and project options of the F7 button. None work. The Sony manual mentions about a ‘licence compatibility issue’ which I do not understand. I have emailed both Sony and LG but neither has offered a solution. I would value anyone’s help. Thank you. Phil
