Paul was recently gifted an Apple Cinema Display. But it doesn't light up if he plugs it in. Leo says there's no on/off switch on that old ACD. You just have to plug it into a computer that has a display port to get it to turn on. You may need an adapter for Display Port to HDMI.
Paul wants to also know what's the best streaming box. Leo says that Roku seems to be the most compatible, but some ISPs have deals with other boxes like Apple which can give it better programming or preferred traffic. So Apple TV may also be a good choice depending on your ISP.
