I also met with all the players the same problem, I am win7 64-bit system, playing all the stand-alone game on both sides have black bars, modified the registry does not use.
Later, a problem was found, which also modifies the value of the registry scaling.
Generally on the web search results are: The Start menu in search files and programs to play regedit into the registry. then expand. HKEY_LOCAL_MACHINE---SYSTEM---ControlSet001---control--- Graphicsdrivers---Configuration---and then right click on Configuration, select Find, input scaling, in the right box can see scaling, right button scaling select Modify, the value to 3, the original value of 4.
The following actions do not resolve the problem after you modify this registry:
1: Enter the registry. And then expand. HKEY_LOCAL_MACHINE---SYSTEM---ControlSet001---control--- Graphicsdrivers---Configuration---then open all subdirectories under Configuration to the root directory, and then look for scaling one by one. Double-click Open to change the value to 3, the original value is 4.
2: Enter the registry. And then expand. HKEY_LOCAL_MACHINE---SYSTEM---ControlSet002---control---graphicsdrivers---Configuration---Then All subdirectories under configuration open to the root directory, and then look for each scaling double-click open to change the value to 3, the original value of 4.
Note 1: Some of the registry will be: ControlSet001. ControlSet002. ControlSet003 ... All need to follow the above changes.
Note 2:1 and 2 the only different places are: ControlSet001 and ControlSet002.
Note 3: The above values must be the same. (Some of the original value is 3, this needs to be changed to 4).
