I'm trying to build a simple game to be projected onto a table to do a small AR demo.
To do this, I need to open the game window in fullscreen mode on a second monitor (projector). I have seen in other questions asked here that there is no way to do this directly in pygame. Can anyone suggest me another way to open a pygame window on a separate display?
I found the answer to my problem by using SDL environment variables before initializing pygame:
x = 0
y = 0
os.environ['SDL_VIDEO_WINDOW_POS'] = f"{x},{y}"
By specifying x, the left border of the window will open in that location.
eg If you have two monitors with resolution 1920*1080 and x=0, the window will open in the left monitor; if x=1920 it will opened in the right monitor.
Since I also want the window to be fullcreen without a border I specify the flag NOFRAME in set_mode:
screen = pygame.display.set_mode((screen_width, screen_height), flags = pygame.NOFRAME)
No way to test(now)
if that solves exactly your problem, but display has
set_mode(size=(0, 0), flags=0, depth=0, display=0)
which features display argument
