Getting HTPC video to 2nd TV.

depending on your video card just a set of rca cables and bluetooth mouse/keyboard.

A little more information would help.

What interfaces do you have avalable on your graphics card that also exist on your such TV-Out(s_video), (HDTV-Out) YprPb componet etc?

What cable types will you be able to run between the systems, if not cable how to want or plan to get the content to the Bedroom TV?

How do you plan or want to control the HTPC from the Bedroom?

What inputs does your tv in the bedroom have? I think that the hdmi is disabled if dvi is used and vise versa. You would need to use some type of adapter to go from VGA to composite/component/svideo. Also would need to get like a headphone to dual rca adapter for audio. That is what I think if you plan on keeping with onboard. All of these are available from monoprice i think.

just get an extender...

What is the source of the programs that you are receiving in the HDTV that you also want to play on the Bedroom TV?
You can get an IR repeater at Radio Shack that works over you home wiring so can use you MCE remote in either location.
If the HDMI interace on your IGP also supports audio(not all do) then you would need an HDMI to RF coax transcoder to us your existing cable.
Are you currently using a wirless router to establish a home network?
