To send a video signal from a computer to a television requires one of the following:
  • A computer with a composite video card installed. (A laptop will not have one.)
  • An S-video output jack. (This accepts a round, multipin plug; many laptops have this.)
  • A converter box for converting the SVGA signal to something else that a television can handle, such as composite video, S-video, or component video. (Such boxes are available at Radio Shack and elsewhere for about $100.)

The computer's VGA (SVGA) video output and the television's composite-video (RCA yellow) input are so different that there is no simple cable conversion. There is no software that would cause the computer to output analog NTSC video onto the VGA port.

No. That may be a hardware limit. You might try and start your laptop in VGA mode to get to 640 x 480
