Hi jer! The TU8000 features 3 HDMI, 1 composite (Yellow, White, Red), and 1 coaxial connection for antenna, or certain cable boxes. Samsung TVs are compatible with the majority of universal remotes, consult the remote manual for the pairing code with Samsung TVs. Alternatively, the One Remote included with the TV can control a wide range of devices connected to the TV eliminating the need for a universal remote. ^Tim
