A:Answer HDMI are the best wires to use. It has two options for sound system. ARC, which uses HDMI slot, or a Digital Optical Audio Output. Again, HDMI works best. It has two USB ports. I plan on buying a keyboard for it. It also has a Component Video Input, and a Composite Video Input. Those are the multi color plug ins, mostly for older equipment. You can hook a cable, or antenna, directly to the television. There's a couple more, but I don't have a use for them myself so I can't advise you on those. It is also Bluetooth enabled. It comes with a power cord.
