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
```

Flags For Initializing a Display in Pygame

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)
```

Using the display module, you are able to:

- Initalize/uninitialize a display
- Create a display surface
- Update the display

Using the Display Module in Pygame

Pygame Documentation

Note that display.init() should be called during pygame.init() automatically. Also, quitting (uninitializing) the display will stop showing every Surface drawn on the display Surface. You can initialize, check initialization, and unitialize a display with the following commands:

```Python
pygame.display.init() 
pygame.display.get_init() #will return true since display is initialized
pygame.display.quit() 
```

Create a Display Surface in Pygame

There are multiple functions for updating displays--display.flip() and display.update(). Flip will update the whole display, whereas update will update only a portion of the screen (either a rectangle or a list of a rectangles). These functions are demonstrated below.
```Python
pygame.display.flip() #updates entire display surface
pygame.display.update(rectangle) #updates a rectangular portion of display
pygame.display.update(rectangle_list) #updates a list of rectangular portions
```
