Hi I’m a OpenGL game developer,and I’m trying to figure out how to enable 10bit per channel output from GPU to display. I currently have Dell 4k display UP3214Q that is capable of working in 30bpp modę. Its connected through Display Port 1.2. Will specifying 10bit per channel during window and ogl connect creation be enough? Assuming I’m rendering to at least half float per channel render target?
Please have a look at the OpenGL pixelformat selection inside the “Whitepapers, Sample Code, Demos” section on this site:
Mind that the Win32 API ChoosePixelFormat() won’t work. You must use the wglChoosePixelFormat() extension function.
If that doesn’t work, it’s most likely not a supported feature on consumer boards.
