I have done vhdl code for color changing on monitor through vga port of spartan3E and it works successfully but i am not able to display image on monitor. As we have 5 out pins to vga i.e hsync,vsync,red,green and blue ,i am not understanding how to assign bits of pixel to red, grren and blue out of vga. which image format is compatible with vga. If we have 8 bits per pixel then how to assign this to out pins?

You can try implementing for smaller sizes but as these devices doesn't have DSP blocks and low density devices these are not suitable for larger video sizes or video applications.
