basically, modelines are a way of telling your video card
specifications as to how it should output a signal beyond just the
resolution. It is required no matter what output you are using, though
used in different ways by the driver/hardware and the output you end
up using. There are two groups of modelines in that wiki article,
standard modelines, which should work with a variety of hardware, then
custom modelines  at the end for VGA/DVI output that users have
submitted so that others with the same TV's can benefit.

If your connecting to your tv via DVI/HDMI, and you have not disabled
EDID, you should see EDID information in your X.org log gathered from
your TV, including "recommended" modelines, from which you can
probably cut and paste into xorg.conf or you may have to slightly
modify.
