Three solutions to failure to play full screen games in Windows 7

Procedure:

1. Nvidia graphics card

To solve the problem of N-Card full screen gaming in Windows 7 (the same for Windows XP), take the following steps:
1. Right-click the blank area on the desktop and select "NVIDIA control panel ";
2. Select "display" on the left-side: adjust the desktop size and position. (for some, "change the scale of the flat panel display". The different video card driver versions are different. Find the scaling settings)
3. Select "use NVIDIA scaling". If the original settings are on this option, apply them and confirm them.

II. AMD ATi graphics card

1. First adjust the screen resolution to a non-optimal resolution state, such as (1024x768)
2. Right-click the video card settings center;
3. select the "configuration" option, click "properties", change "aspect ratio" under "zoom options" to "full screen", and click "OK, go to the screen resolution settings page again and set the resolution to the optimal resolution of the screen (for example, 1366x768 or 1440x900.

III. General solution to full screen game problems in Windows 7 (if the first two methods are invalid, use this method ):
 
Tip: It is risky to modify the registry. Back up data in advance and operate it with caution under the guidance of a professional.
1. Win key + R Key, open the run window, enter regedit and press enter to open the registry editor;
2. Locate the following locations:
HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \ GraphicsDrivers \ Configuration \
Right-click Configuration, select search, enter Scaling, find scaling in the right box, right-click scaling, and modify
Change the value to 3 (the original value is 4). This method basically kills the full screen problem of all Windows 7 games.
For example, some users find:
HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \ GraphicsDrivers \ Configuration \
BNQ7820G5904027026_14_07D9_0D ^ 982BE6B19D3412E0FED7CFC9082CBA39 \ 00 \ Scaling
Change the Scaling value to 3. In this example, the number BNQ7820G5904027026_14_07D9_0D ^ 982BE6B19D3412E0FED7CFC9082CBA39
The display device varies, and the key value found by everyone prevails !!
The above three methods basically solve the problem that all games cannot be played in full screen mode. We recommend that you use the first two methods first, which is easy to use. After all, there is a certain risk of modifying the registry.
