Is this a question or advice? If a question and you have a PC (or anything else for that matter), you need a video out. Laptops by default have these as laptops are typically used in the business world to connect to overhead projectors where someone can show a powerpoint slide presentation or whatever. If you have a pc and your video card does not have a video out invest in a new video card with this. Typically today many video cards have two video "out's". The driver software will let you set the mode to clone your dekstop to the 2nd video out and have that connected to your tv video in. Do full-screen video on your pc and this will show right on your tv, etc.
Been doing this awhile, very easy to do, just find out what connectors you have for what type cables you need. My gear is a couple years old and my video card is DVI where I have a DVI->HDMI cable that connects to my tv. Now after, I chose on another pc to use a dvi->hdmi converter that connects to the card then just get the hdmi cable needed. The DVI->HDMI cable turned to to be quite thick where HDMI is very thin. Invest interest in signal/cable length, I don't know hdmi off the top of my head but my dvi->hdmi is a 25ft cable and is within maximum distance (wikipedia is your friend here.) For instance an Ethernet network cable can only go 330ft before a repeater is needed, etc.
The one thing you'll probably find is that it's best to match your desktop resolution to what you want on your tv. Typically you can set the software to diff res's for the different sources and it works but even with my good nVidia stuff it just doesn't work out as desired. The one monitor I have on my vid out to tv is a 20" flatscreen 1440x900 native. This doesn't work out right on my tv so I kick up the res on the monitor to 1920x1080 to clone to the tv.
I watch the MX races on tv and recorded races through the season on tv when desired. It's a great and easy thing to do.
I'd say unless your a computer tech head and know what your doing and why, don't spend over $150 on a new video card (which benefits in many ways besides just dual video out's.) cheap guys (which is a good thing too), you could probably find a $50 card w/the 2 outs once you look into it if this is all you want the card for.

(as opposed to a shameless plug, but of which I have no affiliation with besides being a customer, do NOT pass "go", do NOT buy an HDMI cable for $30-40-50 bucks, goto newegg and buy whatever you need. (rip off anywhere else whom is not a computer parts retailer. (even if it's not computer parts but just an hdmi cable for instance.) newegg rocks! eggcellent!)) (luv newegg
