|You will need to figure out what types of inputs your TV has, IE. HDMI, component, composite, s-video, etc. Then you will need to find out what type of video out (if any) your computer has. If it doesn't have the proper outputs, you can purchase a video card that would have the output you need.|
HDMI will give you the best picture and will also carry the audio.
Component is the next best, you will need separate audio cables for this.
s-video is probably the next best, you will need a separate audio cable for this.
Composite is the next best, you will need separate audio cables for this too.
