The specific settings are as follows: Enter the game, press F11 in the game, and the game will change from window mode to full screen mode. If you can't press F11, it may be that your display screen is wide. You need to right-click on the desktop, select the NVIDIA control panel, select the option to adjust the size and position of the desktop on the left, and select Do not zoom in the second option on the right. OK, and then enter the game to complete the screen. Whether full screen is possible is related to your graphics card program. Some are forced to scale, so when playing, both sides are black and cannot be full screen. Some are stretched by default, so full screen can be achieved.
