The DC has nothing to do with monitors because monitors are just
different coordinates on the same (virtual) screen. (Obviously since
you can drag the window between monitors, even such that it's
partially on two monitors at the same time.)

It is the size of whole "(virtual) screen" that we want to know here,
rather than the size of a particular monitor.

Then use
        w = GetSystemMetrics(SM_CXVIRTUALSCREEN);
        h = GetSystemMetrics(SM_CYVIRTUALSCREEN);

I tried to use CreateDC
because the reference says:

  If there are multiple monitors on the system, calling
  CreateDC(TEXT("DISPLAY"),NULL,NULL,NULL) will create a DC covering
  all the monitors.
