well, the obvious first step is to try an HDMI connection to your TV.
Get an inexpensive HDMI cable at Wal-dump and see what happens. You may have to do some graphic card driver settings, or you may not. Depends on how capable the graphics chip is at determining what the external "monitor" is.
If the HDMI test works, then consider a longer HDMI cable from

Let us know how the experiment goes so we can help with problems, if they appear.
I did this with my Dell Studio notebook, and it "just worked". However, now I have both a Rolu HD-XR box for one TV and a Western Digital TV Live Plus for the other TV to stream Netflix and other internet content. Hooking up and un-hooking the notebook from the TV turned into a pain....and wifey was not about to fool with it, so the streaming boxes ended up the better choice.
