It comes with both DVI and VGA ports (among other) cables were
I checked, both ends of the cable has 15 pins

Cool, but I have no idea how else I can approach this methods. I have
i810, nv and the nvidia drivers as available options.

I am guessing it's with the TV... I believe the TV simply doesn't
report properly but is in fact capable of what it says (in the manual)

I was focusing on 1280x1024 and eventually got it using simply
system-config-display. Then I realized I actually wanted 1366x768 I
may have given up on that a bit too early.

The first problems were based around the face that Xorg could not
determine the appropriate modes, and so was rejecting the modes that I
put in place. the EE messages reflected that.
Further attempts were due to the fact that what ever mode was being
translated to the TV, the tv reported "unsupported mode" ... no useful
EE messages, I will go back in and check again for WW with 1366x768 at 60
with the nv driver.
