Google for a VGA to HDMI converter. They range from cheap to expensive. TBH, I'd consult a geek about it. You are not just going to need one of those, but a switcher of some sort (unless built into the converter) unless you fancy getting back there and changing cables all the time!
How far away is your TV? Don't forget to factor in the cost of an HDMI cable that goes that far...

My Tv is about 10 ft away from my bed/pc..I see this as usual is going to be a pain in the butt to do Argggg!.....maybe I'm better off just watching things on my 24" PC desk monitor for now.
