This is an old laptop from around 2011, with a pentium p6200 and no dedicated GPU, and I was fiddling around in the display settings when I saw that differenet programs show the built in display as having different bit depths.

Windows display properties shows the bit depth is 8 bit .

The display adapter 'list all modes' list shows that it's running at 32 bits, ( View: https://imgur.com/zi6CFiU
, and no matter what option I choose, windows display adapter properties ( View: https://imgur.com/QmBB1tS
) still shows the display is 8 bits.

And HWinfo shows that bits per primary color is 6 bits. ( View: https://imgur.com/ew9tikZ

Which means bits per pixel is 18 bits?

I am confused as to what the actual bits per channel and bits per pixel of this monitor is.
Anyone know what's going on here?
