SetMonitorContrast() - SetMonitorContrast function (highlevelmonitorconfigurationapi.h)ДЄll of the above High Level Monitor Configuration API functions appear to have requirements of:.

SetMonitorColorTemperature() - SetMonitorColorTemperature function (highlevelmonitorconfigurationapi.h).

SetMonitorBrightness() - SetMonitorBrightness function (highlevelmonitorconfigurationapi.h).

GetMonitorContrast() - GetMonitorContrast function (highlevelmonitorconfigurationapi.h).

GetMonitorColorTemperature() - GetMonitorColorTemperature function (highlevelmonitorconfigurationapi.h).

GetMonitorBrightness() - GetMonitorBrightness function (highlevelmonitorconfigurationapi.h).

Looking at the Windows App Development topic Monitor Configuration Functions which contains a list of functions, there are several that you may find useful. To develop Monitor Configuration, you need these headers: The Monitor Configuration topic mentions: Internally, the monitor configuration functions use the Display DataД¬hannel Command Interface (DDC/CI) to send commands to the monitor.

Reset a monitor's settings to their factory defaults.

Change image settings, such as brightness and contrast.

Change a monitor's geometry settings, such as the width and height of the display.

You can use the monitor configuration functions to get informationДЇrom a monitor and to change a monitor's settings. This API is used with a physical monitor handle which implies that it is for the entire monitor's screen and not individual windows displayed on the monitor. While I'm not sure this is how they are doing it, it seems to be the most likely approach. Microsoft provides the Monitor Configuration functions which use the Display Data Channel Command Interface (DDC/CI) to send commands to a monitor. The last approach, working only on your own application's window, would be to apply a shader to your window. The next most compatible approach would be to use the Magnification API. This one was available since Windows Vista, and thus is available on currently (2020) supported Windows versions. Yet another highly compatible API would be within Direct3D 10-12's DirectX Graphics Interface - DXGI, specifically IDXGIOutput::SetGammaControl. It offers SetGammaRamp, with same data table format as that of SetDeviceGammaRamp above. This family of APIs may fail if you try to do 'too much'.ДЄnother highly compatible API would be within Direct3D 9 (available since Windows 98 and XP). There is a caveat: Windows doesn't allow compressing the color too much, and it's quite arbitrary about what it allows. The function to use is SetDeviceGammaRamp. The most legacy-compatible way would be to use the Windows Color System APIs, supported since Windows 2000. There are three generations of those APIs: Windows itself performs monitor colorspace calibration using the 'gamma ramp' system: a lookup table, historically used mostly for linearization of the monitor response, and subsequently used as a kitchen sink. With that out of the way, there are several ways that Windows could implement it, but we don't care because we're not writing a direct replacement for the Windows Night Light component. its presence in the kernel would cause PMP-using applications to refuse to play protected content), and perhaps quickly at that.

And you'd not dare put it on the web, because Microsoft would blacklist that driver (i.e.

To get around PMP you'd need to write a driver, sign it using an EV code signing certificate, and then submit it for automated attestation signing by Microsoft. from Netflix, Hulu, Youtube Red, system DVD player, BluRay player, etc. So: whatever night light you may implement by accessing the screen contents, won't work as soon as any protected content is displayed, e.g. And most certainly, under Windows you have no unfettered screen access, not least because of DRM: there is a protected media path (PMP) for protected video and audio content, and you won't be able to sniff it from an arbitrary process. Just because 'the os should be able to access the screen' doesn't mean that you (in userland) should be able to do that. It's not always a valid expectation that the OS will allow you to do what it itself does.
