DE2 Board and Using VGA output

Question

I'm trying to use the VGA output on the DE2 board and I cannot get anything to work.  I've tried looking through Altera's documentation, and searching the web, but I can't seem to find anything that explains it or has any decent examples.  If anyone had an example, even for just turning the entire screen blue or red or half and half or something really simple, it'd help me out a lot.  Thanks.

You should read the VGA SPEC. A certain timing is required to make the monitor recognize a valid mode. For Xlinx, there is an example project out somewhere called vgatest.vhd. You might search google for code to find it.
