As you describe I would let the user position the scoreboard one, store
the setting and then re-use it for the lifetime oof the projector.
It's simple, gives the user hardly any work but complete control.

I'm doing the same with a window that is specially for showing planned
matches, matches that are on court and matches that have been played.
This process runns on a separate PC that id mainly used for that purpose.
While running in a loop it uploads the tournament progress once in a
while to the Internet.

I don't think they're listed there. You can use the following prototype for
Enumerate display monitors:

_DLL FUNCTION EnumDisplayMonitors( ;
hDC AS PTR, ; // HDC handle for your app
lprcClip AS PTR, ; // clipping rectangle (option)
lpfnEnum AS PTR, ; // callback function to enumerate
dwData AS DWORD ; // Private data passed to callback function
) AS LOGIC PASCAL:User32.EnumDisplayMonitors

I haven't used this function but, from top of mind, something like this could
do:

STATIC GLOBAL hMonitor AS PTR // Your monitor handle

FUNCTION FindMyMonitor( oShell AS Window ) AS PTR PASCAL
// Finds the monitor handle where <oShell> is displayed
LOCAL hHDC AS PTR

hMonitor := NULL_PTR // start clean
hHDC := GetDC( oShell:Handle() ) // Get window DC
IF hHDC <> NULL_PTR
EnumDisplayMonitors( hHDC, NULL_PTR, @EnumMonitorsProc(), 0u )
ENDIF

RETURN hMonitor

STATIC FUNCTION EnumMonitorsProc( ;
hHandle AS PTR, ;
hHDC AS PTR, ;
pRect AS PTR, ;
dwData AS DWORD ;
) AS LOGIC _WINCALL
// Callback function for EnumDisplayMonitors()

IF hHandle <> NULL_PTR
hMonitor := hHandle
ENDIF

RETURN TRUE

HTH,

Amilcar

Thank you very much for that. You have been very helpful (as always in this
forum).
