Hi there! The Samsung TU8000 is a Smart TV, which will allow you to choose and download from hundreds of apps in the built-in App Store. If you wish to connect any external devices (PC, gaming console, cable box), you may do so via HDMI cable; however, since this is a Smart TV no external devices are necessary. The TU8000 has 3 HDMI ports, 2 USB ports, 1 LAN port, 1 Optical Output port, and 1 Composite (AV) Input to seamlessly connect your TV to any device you wish. ^Gina
