After I've connected the cable to both ends my nVidia control panel still doesn't recognize the 2nd display which is a Skyworth LCD with a perfectly fine regular HDMI input.

I have the newest graphic card driver installed.

What to do?

My nvidia card needs to go through a boot sequence with the TV attached and powered on before it recognises it. – Xyon Nov 15 '12 at 13:03

If you have a laptop, make sure the video output is configured. Usually you can find a key which looks like a monitor symbol in the function keys, mine is F4. Hold the down function key (by the start key) + press F4, then you should be able to select the display output. This may varies from between laptops depending on manufacturer (mine is Hewlett Packard).

Also the TV must be set to receive from the HDMI port which you have connected the cable to.
