Well it depends on what you are connecting to the TV. Are you trying to figure out how to connect the PC to the TV? Because this depends on what kind of graphics card you have. There are DVI to HDMI Converters if the graphics card on your PC has a DVI slot on the back of it. Also you can look into all sorts of other types of converters such as VGA to Component and I beleive there are converters to RGB. Just look on Amazon for any of these things for under $5.
