This is a slightly more advanced TV's back panel. On this particular TV, the HDMI inputs are on the side. The PC input is the same connection found on most computers, also known as RGB-PC or D-Sub 15. Check your TV's owner's manual to find out what resolutions this input can support (if so equipped). It may not be 1,920x1,080. The "Video In 1" is the composite input, and is not HD.
