Q: how to turn off overcast

I have looked at the apple page for playing about with overcasting, but as you can see from the image above i went to the same location yet my laptop seems to lack the overcast option, so if anyone knows where to find it, it would be much appreciated.

Thanks for the help.

As shown in my screen shot above I don't appear to have the same as what they use to demonstrate, so is it accessible somewhere else on my mac?

As stated in the support article, the setting is only available when a TV is connected.

You need to configure it on the Chromecast or TV - a wifi connection to another device is not going to support the same features as a direct cable connection.

The other option you have is to use a cable & connect directly to the TV. See Chromecast's manual or it's user forums for info on how it handles overscan.
