Official specifications been made to recognize the DIB/BMP files with color depth 2bpp.
But why not make support DIB / BMP 2bpp in IrfanView?
Quite often need to work with non-compressed graphics resources, the simple structure of the DIB/BMP is suitable for this, but the inability to view, and convert from/to the DIB / BMP 2bpp very disappointing.
To advanced users possible add option in settings:[*] Switch on the DIB/BMP 2bpp
