Hello I am developing a game and I want it to be fullscreen and I was looking around on the wiki and I wasn't quite sure what the proper way was to make the game fullscreen. 1#include <allegro5/allegro.h>
2#include <allegro5/allegro_image.h>
3#include <allegro5/allegro_primitives.h>
4#include <allegro5/allegro_font.h>

6#include <allegro5\allegro_acodec.h>
7#include <allegro5/allegro_ttf.h>

Most monitors don't support 1000x800 screen resolution. Try something standard, like 1024x768 or 1280x1024, or better yet, query the available modes and pick one that's about the right size you want. See here.
