OpenGL formats in different modes


Is it possible to find out what OpenGL formats are available in all modes not really switching to them because it’s too long and unpleasant method. I know under Direct3D it’s possible.
Is there any valid assumption like for example: for all 32bit modes OpenGL format set is the same and etc.


No, pixelformat enumeration results depend on the actual display settings. The number and types of pixelformats rely on the available frame buffer memory and HW possibilities in the chosen color depth.
