    You need to understand VGA timing, how "new" are you to VHDL? Anyway, the DE1 User's manual has a section on VGA timing. You basically need to generate those signals. Here is more information for higher resolutions:

    Good luck.

    You should take a look at the University Program from Altera

    ftp[dot]altera[dot]com/up/pub/Altera_Material/10.1

    The component is called "altera_up_avalon_video_vga_controller"

    Good luck

    Speaking of Altera wiki I forgot that I posted sample VGA VHDL for DE1 :D:
