Hi everyone, I got a Optoma Neo-i projector for Christmas and I want to use it to watch sports outside on my deck when the weather is nice. It has an HDMI port in the back as does my Time Warner digital cable box which is currently connected to my TV. Do I just need an HDMI cable in order for the cable TV to work through my projector or do I need some other connections etc? It has speakers built into the projector so I don't think I would need anything else for sound but I'm not sure on the video connection. Also will I have to change the mode or setting on My TV for the signal to go to the projector? Sorry, first timer here and not too savvy. Thanks.
