WOW RGB format? RGB is colorformat has hardly anything to do with NTSC or PAL. All tv's are RGB, all print is CMYK. The console will prolly be ntsc or pal. DOn't know much bout consoles.
It just says NTSC because ebay doesn't make a difference in console and pc games, so it just says NTSC, just ignore it.
All monitors and TVs use RGB to present the graphics, but the data in sent to them with different encoding. Different types of encoding include PAL, NTSC, RGB and more. Your monitor or TV needs to be able to understand the encodig to display the graphics properly.
I think console games have the graphics saved to the disc in PAL or NTSC format, or they have specific converters in the software. I'm not entirely sure why it is done this way. Since PC games are assumed to be played through a monitor, the graphics is saved in RGB format.
