Connect the HDMI cable to the TV and press FN and F8 together on the keyboard which will cycle through the input options. You may have to cycle through (press FN and F8 a couple of times)

Thanks for the response. I tried what you suggested and gave it some time before I cycled the next FN/F8 until I got back to the start. All I got was a blank screen or the Invalid format on the TV screen. Any other suggestions?

On the TV, have you changed the Inputs to cycle through to the correct HDMI connection?
