Hi, i have a code which i want to program to turn computer screen off using matlab function. I do find code which shut down the computer such as system('shutdown -s') but i just need to turn the display off. Could anyone suggest me how to turn it off? I am using window 7. Thanks.

There are many possibilities, which can be easily found by asking your favorite internet search engine:
One solution:
system('%systemroot%\system32\scrnsave.scr /s')
WinPower('monitor', 'off');
This does not stop the processing. If the computer whould sleep also, use: Winpower('sleep').

Thank you Walter! But I really need a code, so I can use it in my program.

I am not even close to being a Windows specialist, so I might have missed something, but the information I find suggests that Windows 7 through to earlier Windows 10 only support screensavers on the primary monitor. Later Windows 10 by defaults shows the screensaver on all monitors, and has provision to configure the screensaver to display only on particular monitors, but not to configure different monitors with different screensavers or different timeouts.
So far I only see the following commercial product indicating support for different screensavers with different timeouts on multiple monitors: https://www.actualtools.com/articles/detail.php?ID=1392

Trying to use WinPower I get the error "== InstallMex: failed."
>> mex -setup
MEX configured to use 'MinGW64 Compiler (C)' for C language compilation.
For manually compiling I get
>> mex -O -largeArrayDims -D_LITTLE_ENDIAN -DHAS_HG2 -DMATLABVER=907 WinPower.c -v
Error using mex
C:\Users\aktiv\AppData\Local\Temp\mex_237481349027607_8440\WinPower.obj:WinPower.c:(.text+0x238): undefined reference to

collect2.exe: error: ld returned 1 exit status
Any idea? Thanks in advance...
