Hello, when i connect my vga cable to onboard mobo… it displays well, but when i switch off a pc and put in a graphic card… .it start well with a beeping sound but i get nothing on display… it shows well onboard even if my cable has a problem with colour red, it does not display a colour red because its broken… so my main question is… do the graphic card displaying rely on the full colour pallete… or it also has the possibility of playing with a lacking colour pallette… .please help.
