|
|
|

lpDevMode

dwflags
[in] Indicates how the graphics mode should be changed. |
|
|
| Return value: |

| My comment: |
|
Specifying CDS_TEST as dwflags allows an application to determine which graphics modes are actually valid, without causing the system to change to that graphics mode.
To change the settings of a specified display device, use the ChangeDisplaySettingsEx function. |
