It looks like you are not there. I do not know the model of your Sanyo device yet, so for now, let me provide a general solution. When you are available, please reply back to continue.
- I've checked your Gateway computer model zx6971; it only has an HDMI-in port, so it can only accept content from another computer (laptop or desktop.) Your computer model does not have an HDMI-out port, so it cannot display the content from it to a TV (or to a computer monitor.)
- But there is a solution, you can purchase a USB to video / graphics adapter from your local computer / electronics store (or online), then install / connect it to your computer. Then connect a cable from the adapter to the TV, then you can display the computer's content to the TV's screen.
- Please tell me the exact model your Sanyo device, so I can let you know the exact type of adapter you need.
