That says nothing to this Gentoo user...
FWIW, the latest KDE is version 4.6.3, just out Friday. However, the 4.6
series has been a bit problematic. You may be better off with 4.5.5 or
possibly 4.6.0, than with the newer 4.6.1 thru 4.6.3. But YMMV as they
say...
To figure out your current kde version, check the help, about kde, menu
option in pretty much any kde app.

The multiple monitors kcontrol applet only activates /after/ you have the
second monitor up and running.
What you would ordinarily want instead is the Size and Orientation kcontrol
applet. You may also find the krandrtray system tray applet useful.
However, depending on your TV and graphics hardware, these may not be able
to detect or activate the TV, especially if it's an old-style analog TV --
an HDMI or DVI digitally connected TV is far more likely to be detected
and "just work". Additionally, if you run proprietary drivers such as
those available from nvidia and amd/ati, you may not have the normal randr
based setup, as they tend to be slow about adopting such things, and would
probably use their proprietary tools shipped with the drivers, instead.
If the kde tools aren't working (and you aren't running proprietary or old
xorg drivers without randr support), you can try xrandr, in a terminal
window (konsole or xterm or the like). It's an xorg CLI based app,
meaning you'll probably need to study its manpage to figure out the
various command-line options you'll need, but it's more flexible than the
kde graphical tools, and often works where they won't. A simple "xrandr"
should spit out the outputs it sees and their status, however.
If that too fails, you may need a customized xorg configuration. Again,
this is far more likely with old analog TVs or legacy analog connections
to digital TVs, and possibly with proprietary drivers. If you find
yourself in this situation (and it's not due to proprietary drivers), post
a reply with a few more details on xorg version, graphics driver, kernel
version, etc, and I may be able to help further. But I don't do
proprietary (see my sig for why), so if you're using those drivers, you'll
probably have to find help elsewhere.
