Core duo with 32"LCD TV slight problems

Question

Hi there!
I've decided to buy an LCD High def telly with HDMi input. So I puchased a DVi to HDMi lead and everything looks great on the telly when set at 720p.
Only thing is, the top and bottom of the screen are missing so I can't see the menu bar. To cure this i've used switchresx control panel to alter the settings to achieve a lower resolution, of around 1102x620. After messing around with the front porch (or whatever you call it) the picture is now central and pretty much fully visible.
But I can't help but think that i'm missing out on some pixels! Is there any way I can run it at the full 720p or 1366x768 and adjust that resolution to just fit? It's like it just needs shrinking a little.
It's also worth pointing out that this is with overscan turned on. Without overscan the picture doesn't fill the screen and has black borders.
Thanks in advance for any replies, am glad theres a dedicated community out there!

Hiya, thanks for your replies so far.
Which frequencies should I play with? I shouldn't really go away from the native vertical frequency of 50hz should I?
It's an Acoustic Solutions LCD32KD750HDF. With overscan off I can't really seem to get any setup that doesn't have a big black border, plus there are no settings possible on the telly when running through HDMi, it is fixed at whatever is being inputted.
It looks great at 720p with overscan on, it's just that the top, bottom and sides are cut off so I can't see the menu bar. Also when running front row, the time display on a song disappears of the edge of the screen.
As I say, i've lowered the resolution slightly to achieve visible screen - but it just seems to be defeating the object. The televisions native display is 1366x768 pixels, but I can't get a setup that will make that work at all.
Again, I do apreciate all responses.
