Hi, searching the forum a bit, I tried to implement a screenshot of
one of the monitors of the PC on which the program runs.

I attach example that doesn't work as it should. The screen of monitor
0 works well, from the second onwards I'm doing something wrong.

Who can help me? A thousand thanks

You are in trouble with different DPI and the resizing of the
monitors.

If the monitors are differents DPI and / or different resizing, you
must calculate the real dimension (may be quote X and / or Y) of the
corners.

I never tried to catch a single part of a monitor, but for sure this
should be the problem.

Instead to calculate "by code", sets the property in the projects
option DPI AWARE PER MONITOR V2
