Short for National Television System Committee, NTSC is a committee responsible for video standards in the United States, South Korea, Taiwan, Japan, Philippines, and other locations. The NTSC television standard defines a composite video signal with a refresh rate of 60 half-frames (interlaced) per second. Each frame contains 525 lines with up to 16 million different colors.
When configuring a desktop computer or laptop computer to connect to an external video source users in the United States should configure the video or BIOS for NTSC. Users outside the United States should select the option for PAL.
