Say you want to have your display launch as a hidden window that goes fullscreen when clicked on. You can store the flags inside a variable called flags and then pass it into display.set_mode() as shown.
```Python
flags = pygame.FULLSCREEN | pygame.HIDDEN   
#store flags for fullscreen and hidden in variable 'flags'
window_surface = pygame.display.set_mode((1920, 1080), flags, vsync=1) 
#create a display of size 1920 * 1080p and with the fullscreen and hidden flags
```

Code Example of Initializing Display with Flags in Pygame

There are multiple flags you can choose when calling display.set_mode() to customize your display. You can chain multiple flags together using the or operator |.
```Python
pygame.FULLSCREEN    #create a fullscreen display
pygame.DOUBLEBUF     #recommended for HWSURFACE or OPENGL
pygame.HWSURFACE     #hardware accelerated, only in FULLSCREEN
pygame.OPENGL        #create an OpenGL-renderable display
pygame.RESIZABLE     #display window should be sizeable
pygame.NOFRAME       #display window will have no border or controls
```
Pygame 2 includes the following extra flags:
```Python
pygame.SCALED        #resolution depends on desktop size and scale graphics
pygame.SHOWN         #window is opened in visible mode (default)
pygame.HIDDEN        #window is opened in hidden mode
```

You can create a display surface by using the set_mode method on pygame.display. It will take in five parameters: size, flags, depth, and vsync. The size is the width and height of the desired display. The flags param controls which type of dipslay you want. Depth dictates the number of bits to use for color, which should be left empty since pygame will automatically find the appropriate color depth to display. The display param Vsync allows you to enable vysnc on the game, but requires certain flags to be set and may not work depending on hardware specs of your machine. The set_mode command is shown below.
```Python
pygame.display.set_mode(size=(0, 0), flags=0, depth=0, vsync=0)
```
