Hi,
I got a question about how to use SetDeviceGammaRamp Function.

As in SDK, Remarks said:'*SetDeviceGammaRamp* succeeds only for devices with
drivers that support downloadable gamma ramps in hardware.'
And I tried in my pc, the function return FALSE. but in my friend's pc, it
work well.
Maybe my pc doesnot support downloadable gamma ramps.

So How do I know if my device support that?
What's the definition of downloadable gamma ramps ?
And what kind of device support that?

Thanks so much!
