Generally "32 bit" is 8 bit Red, 8 bit Green, 8 bit Blue, 8 bit Alpha = 32
bits per pixel.
In fact, if you have the proper monitor, the proper graphics card, it is
possible to run 32 bit color as: 10 bit Red, 10 bit Green, 10 bit Blue,
2 bit Alpha, and Proper cable (Display Port or Dual Link DVI, or HDMI 1.3a
or later)
Presuming the Graphics card + Graphics card drive + Monitor support it,
Windows allows per application Bit depth - thus it is possible with to have
40 bit color, aka, 10 bit Red, Blue, Green and Alpha, and even 48 bit
Color ... 12 bits per channel.
To my research, only 10 bit per color is supported by current LCD monitors,
there were old SGI graphics adapters which supported 12 bit per channel,
not sure how it was actually displayed or used..
To be fair, I think there are roughly between 5 and 10 current LCD monitors
which offer true 10 bit per pixel color, most conventional monitors are
truly only displaying 6 bit per pixel color, and most of us are none the
wiser.
