The More HDMI Ports, The Better

One of the best things about HDTVs are their dead-simple, ultra versatile HDMI inputs, which funnel high-resolution audio and video through a single cable. But a single HDMI input is rarely enough for all but the most spartan home theater setups, and even a pair of ports could force you to juggle connections, constantly fumbling behind the TV to attach and reattach consoles, Blu-ray players, or other devices. To be safe, don't settle for fewer than four HDMI inputs. And to accommodate cameras, smartphones, or other gadgets that can pipe stills and video directly to the big screen, consider getting a set with at least one of those ports located on the side of the TV, as opposed to the rear.
