HDMI + too much overscan...

No worries, Skeptic, have fun... Just for future reference if people need it, here is a graphical representation of the screen timings. Imagine the visible screen as being just the top left hand part of a larger "virtual" screen, so that you can envisage the timing positions:


                      |   | |     |
XXXXXXXXXXXXXXXXXXXXXXX---SSS------
XXXXXXXXXXXXXXXXXXXXXXX---SSS------
XXXXXXXXXXXXXXXXXXXXXXX---SSS------

The X's are the visible pixels. The -'s are "no information", then the S's are the horizontal and vertical sync signals. The first timing position is marked by the first | on the top, the next timing position by the next bar and so on. Same for the vertical timings, marked with a <. The width of the screen scaling is proportional to the ratio of the first and forth marking bar for horizontal and the same for vertical.

A few more sync signals and you have the US flag. 

On a more serious note, this is really good info.  I'll keep it in mind as we will soon be replacing every TV and MD as well as buying new ones for new areas when the basement is finished.  In fact, my last two CRT TVs are being sold or dumped this weekend, then replaced with LCD screens.
