Howcan I change the monitor refresh rate in windows 3.11?

I'm not familiar with 3.11 and don't find any setting for it.

Great question!
I'm looking for some better answers, but this is a start:

I hope you do know Sysedit? If you don't bring up a run dialog and type "sysedit". This little program will allow you to edit the config files, including win.ini and system.ini.
One can tweak the system by modifying a few eintries system.ini (italic: speed, normal: stabiliy):

First the [386Enh] section:
[386Enh]
DMABufferSize=64 ; size of the DMA buffer in KB, should be at least 64 KB, on my system it's even 150 KB
FileSysChange=Off ; Changes in the file system are reported to programs which understand it (File Manager). Off is faster.
MaxBPs=768 ; defines the number of breakpoints, default: 200


WindowUpdateTime=5 ; interval (in ms), in which the content of DOS windows is redrawn, default: 50

Read through this link for a lot of WIN 3.11 tips - plus specifics on refresh rates:

WindowUpdateTime=<milliseconds>
Default:  50
Purpose:  Specifies the amount of time (in milliseconds)
          Windows takes before it updates the display oXf
         -> non-Windows applications<- running in a window.
To change:  Use Notepad to edit the SYSTEM.INI file.

That's not what I want. I already googled and found the other articles and clues to use manufacturer specific tools, but I still don't believe, that win 3.11 did not offer that on its own.

Ya, Ich werde fortsetzen zu schauen.

I would like to close the question. I found the option in the VideoSeven-Options which I did not notice at first.
