Hi!

I'm trying to write a little C CLI app that changes the refresh rates of my display.

I've experimented with the following:


mode = CGDisplayBestModeForParameters(dspy,8,640,480,& ;exactMatch);
err = CGDisplaySwitchToMode(dspy,mode);

where dspy is the id of the display.
CGDisplaySwitchToMode allows me in this example to switch to a resolution of 640x480 with 8-bits color depth.

But how can I change refresh rate from 60Hz to 50Hz? CGDisplaySwitchToMode doesn't seam to take any more parameters.

Any ideas?

I think I found the correct function. It should be:

mode = CGDisplayBestModeForParametersAndRefreshRate(kCGDi rectMainDisplay,8,640,480,50,&exactMatch);

Would you be able to make the source code for this tool available?

I'm trying to get started in C development on OSX, and this is exactly the type of utility I'm interested in developing (C code, CLI application, calling into various OSX APIs).

What API is this using? Carbon?
