I'm using SDL in my current project, and when in fullscreen, opengl defaults to 60khz refresh rate (windows xp). From what I can gather, it is beyond SDL's limits to set the refresh rate. But how would you go about setting OpenGL's refresh rate outside of SDL? I know it's possible, a lot of other libraries do it.

You have to use OS specific calls to change that, on Win32 for example you'd do it at the same time as you change the rez and into fullscreen mode

That's what I'm looking for, the api calls to tell windows to use a specific full screen refresh rate.

(I use SDL to set up the window, and resolution, etc)
