TBApiSetVirtualDesktopMetrics API Call



Some video drivers support a "virtual desktop" mode where the size of the Windows desktop exceeds the size of the monitor display area. A program can make this call to report the size (in pixels) of the visible area and the offset of the top left corner from the top left corner of the Windows desktop.


Left, right, width and height


0 = fail, 1 = OK.


Note that this API is used internally by UPDD for certain video cards, but is exposed so that 3rd party utilities can call it in situations where UPDD does not provide native support.
