Hey, I am a complete noob when it comes to computer hardware and such. I have a Compaq SR5605F with a NVIDIA GeForce 6150 SE video chip. I want to hook my HDTV up to my computer as a second monitor for movies and such. I would like to be able have a movie/screensaver on the TV while still being able to surf the web on the original (not tv) monitor. I will have to hook it up using either SVGA or HDMI. What should I be looking for in a video card? Any help would be great because i'm TRULY clueless.
