Cannot see all of my desktop on the screen

[romatech]

So, i've finally got my new Mac Mini and hooked it up to my Toshina 42" TV via HDMI. I've run through the setup and all is well...almost. I find that I cannot see the whole desktop. The mouse cursor vanishes off the edges and there's a menu at the very top that I cannot see.

Any ideas how to fix this?

What resolution is the Mac Mini set to?

It's set to the 'best option' for the display which I think should be 1080p. When I do into the Display preferences I don't see any resolutions available. It has detected that my TV is a Toshiba.

SOLVED: Played around with the 'Underscan' slider and this zooms the display in and out (or appears to at least). Setting it about halfway showed the whole desktop.
