SM_CYFULLSCREEN gives full screen client size, add caption height.
screen_height = GetSystemMetrics(SM_CYFULLSCREEN)
+ GetSystemMetrics(SM_CYCAPTION);

GetSystemMetrics returns the size of a maximized windows, so it removes from
the total height of the window the size of the system tray.
To get the screen size you have to get a DC for the entire screen surface
(GetWindowDC(NULL)) and the use GetDeviceCaps(dc,HORZRES) and
GetDeviceCaps(dc,VERTRES) to retrieve screen size.

try SM_C[X/Y]SCREEN instead of FULLSCREEN. Those work for me.
FULLSCREEN is maybe occluding the space for the taskbar?

If you want the size without the taskbar, use
SystemParametersInfo( SPI_GETWORKAREA, 0, &rect, 0 )
