What should I do if the screen on both sides is Black during Windows 7 full screen games?

Method 1: Change the video card settings

 

• We will install a driver Wizard or download the latest driver installation for the video card.

• Right-click "computer" in the Start menu and click "Manage" on the page to open the page.

•  

•  

• After entering, click "Device Manager"> "Display Adapter"> "XX graphics card driver software" on the left, and right-click "update driver software.

• 
  

• 
  Then we performed step by step so that Windows automatically searched for software updates.

• 
  

•  

• Change the display settings.

• 
  This setting varies depending on the graphics card, some of which are scaled, others are green, and some are directly borderless.

   

  Method 2: modify the registry

  If the first method is invalid, you can modify the registry to implement full screen.

  In the initial search, enter regedit.exe and double-click it to open the registry table editor.

•  

• HKEY_LOCAL_MACHINE----SYSTEM ---- ControlSet001 ---- Control ---- GraphicsDrivers ---- Configuration ---- HWP28423CQ92762B3_1B_07D9_38----00----00 ---- Scaling

• 
  

• 
  Note: HWP28423CQ92762B3_1B_07D9_38 is the value corresponding to ATI Radeon 3100. Different video cards have different node names. However, this node has a 00--00 -- Scaling subitem.

•  

• Find scaling in the left window, right-click it, and click "modify" in the pop-up menu ". Change the value to 3, and the original value is 4.
  If it is 3, I change it to 4, and then I try to change it to 3 to see if it works.
