AMD Radeon HD 7450 - black / white display available on device driver level ???

Dear AMD Team, dear community members,

i am a PC with AMD Radeon HD 7450 graphics card and a windows 10 operating system.

I am developing a C++ application using the Bloodshed IDE and am testing Bitmap Functions of the Win32 API / WinGDI.

The behavior of monochrome bitmaps is rather odd, and it looks as if the MS API isn't either working properly or isn't documented properly (or both).

So i would like to set my display to black/white (=Monochrome) on device driver level, so that regardless of any MS Windows settings, the display is only using two colors to display anything on the screen, preferable the colors Black & White.

The AMD Catalyst Control Center does only allow to set desktop display mode to resolutions between 640x480 to 1920x1080 pixels. BUT always with 32 bit color mode only. Does the AMD device driver does not offer the functionality to switch the displayto a pure s/w mode ???

Or am i just missing how to activate that functionality?

Any feedback is welcomed, thanks in advance, J.R.Horst

This type of question would better fit the Developers forum.... https://community.amd.com/t5/developers/ct-p/devgurus
