What kind of monitor do you have? The times of multi-sync monitors passed by for over a decade now, so I'm not convinced that you can control the refresh rate at all.

It's not getting clear to me, what you are looking for. What is "the content displayed on any monitor refresh (frame)"? Do mean mean a screen shot?

If you are on Windows, you can get and set this using WMI (Windows Management Instrumentation). If you google for "wmi screen refesh rates" there are plenty of examples of how to access WMI and manipulate screen parameters. You'd need to write some code to get at the information, though -- there's not a direct way to get at it in MATLAB.
I suspect that for most monitors nowadays, the refresh frequency is 60 Hz.
Setting your display parameters by running an application seems kind of odd, though -- usually you'd expect an application not to do such a thing.

I don't think so. It's an interface that's used to get information from Windows. I'd suspect that you would need to look more into the technologies behind things like VNC or display drivers to get that information.
You could also look at ways to generate a screen shot automatically and do something with that image.
