This one?
https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-
setthreadexecutionstate

In your case it would be something like (Aircode)
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i Var 
STES:LongWord; //Or some specific Type, probably an EnumBegin 
 STES:=SetThreadExecutionState(ES_CONTINUOUS Or ES_DISPLAY_REQUIRED);
 //Start of "Screen stays online"  //DoSomething 
STES:=SetThreadExecutionState(ES_CONTINUOUS);  //End of "Screen stays
online"End;

Thanks.

I tried this
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.FormClose(Sender: TObject; var CloseAction:
TCloseAction);begin 
SetThreadExecutionState(ES_CONTINUOUS);end; procedure
TForm1.FormCreate(Sender: TObject);begin 
SetThreadExecutionState(ES_CONTINUOUS OR ES_DISPLAY_REQUIRED);end; and
it seems to work.

Easy to check: Set your Power Management Settings to 1 or 2 Minutes.
Just let your computer idle that time away to make sure that it really
turns off your display after that time.
Run your program, and let it run without touching anything (Keyboard,
Mouse), and check if Display turns off

For Windows 11, 10, 8.x, 7 and some other Windows there is an
alternative: a small nice program (184 kb download) which does this
job and many more: "Don't sleep" =
http://www.softwareok.com/?seite=Microsoft/DontSleep

It can:
 - prevent the monitor from going to sleep
 - prevent automatic Standby mode
 - come up in an activated state, so no keystrokes or mouse clicks are
neccessary after you start it
 - be configured with an INI-file and command line parameters
 - start minimized or in the system tray
 - speak many languages
 - does *not* change any system or registry settings
