If just using a Smart TV for a computer monitor, what is the easiest way to keep it from sending your information? Just keeping it away from WiFi? Would it be able to connect via your HDMI?

No problem! You can purchase that hard to find cable at Radio Shack…Oh wait.

I have a nVidia card. Is that bad?

I think it’s hilarious that you show proof of how overpriced Apple products are and there are still fanboys that down vote you.
