You can use this cable to connect to both old-school CRT or Tube Televisions and new Flat Screen Televisions, as long as they have an RCA (Red, White & Yellow) Input.
NOTE: The SEGA Genesis Model 1 and the SEGA Master System do not output stereo sound from the AV port, only Mono. That is why there is only 1 (white) audio cable and no red cable. Red is the “right” speaker in stereo and white is the “left” speaker. When using only a white cable, most TVs will play the sound through both speakers.
