Many newer laptop computers are designed with an HDMI connector for connecting the computer to an external display device, such as a projector or a flat screen television. HDMI stands for "high definition media interface;" it is able to carry both a digital high definition video signal and an audio signal simultaneously over a single cable. When a laptop is connected to an LCD TV with an HDMI cable, the laptop display is expandable to the TV.
