exactly what computer model and tv model. not all tvs will allow hdml pc hookup even though they have an hdml port.

You have to be ensure you are using a TV spec resolution (ie: 480/720/1080 @ 60hz ). You are using a TV input, so you have to use TV spec resolutions.

some tv's will only connect a computer through a vga port

I know it's a basic question but are you activating the tv in the display properties? It will not automatically send video by itself.
