1. HDMI cable. No lag, cheap. Mine is 36 feet long.
2. A WDTV Live. Kind of techy to setup, added a small form factor 2TB Toshiba Canvio Basic for movies and such.
Been searching for ever to find myself a solution and not been able to find out what i need to buy for my purpose. I have checked out Chromecast & Netgear but found that they lag while playing movies. Would be nice to be able to mirror my laptops & mobiles but the most important is just playing video's, dvd's & movies from my laptops to my Samsung TV, my TV has USB & HDMI inputs.
