Thanks rich, that's the kind of theory I was working on.
Thanks Pie, I tried the FnF8 combo, and while it did change the appearance of my screen on the laptop, it still didn't send to the TV.
I also resized the PC screen to a ratio the TV was comfortable with but that didn't help either.
As for Rich's shopping style, buying the VGA cable took about half an hour because, not only did the shop have a really good driving simulator game all set up for customers to play on, there was a pet shop next door with puppies and kittens in the window. Awwwwwww....
