windows display calibration registry key

Hi guys, could anyone tell me what is the registry key referring to the value of gamma when using the windows calibration tool? when I move the slider the gamma value changes. Where can I see this gamma value in the registry? Image: windows display calibration registry key-adjust-gamma-monitor.jpg

I don't think there is a gamma value stored in the registry. I could not find one. The gamma intensity setting is ultimately stored on your monitor.

Windows has APIs for changing the gamma level.

Quote:
All of these APIs operate on the same hardware, and change the same values. The Direct3D 9 and DXGI APIs are write only. You can't read the value of the hardware, modify it, and then set it. You can only set the ramp.
