Hi all! Love the site! Noob here with a question that I've researched a bit (on here and in other places) but either I'm not getting my answer or I'm not understanding it and either of those could be one of my issues. Ultimately I would like to wirelessly connect a laptop or tablet to a flat screen monitor. I've seen the sticks out there (i.e. Chromecast) that allow you to run Netflix, Pandora, and that type of entertainment but I'm looking to do more PowerPoint presentations and show those on the tv. Will Chromecast do that for me as well? Is wi-fi necessary? Thanks for the help!
