I feel almost silly posting this poll, but the recent interest in calibration and a similar question on usenet made me think this might be relevant.

24-bit, 1024x768 on a 21" monitor (not mine - on homeloan from my husband's place of work). Don't know why I don't have it set at 32-bit. I think remember trying it once and it seemed that my video card wouldn't support it. Maybe I should try it again...

This discussion prompted me to check my site stats to see what settings people are using. (The tracker can pick up most system colors used, unless it is an unknown browser type).
Over the past two months, and 1535 visitors, a surprising 31% are in 16 bit mode!
Top numbers are 49.9% at 32 bit, and 41.6% at 1024 x 768 (800 x 600 second) at 31%.
Interesting. I may put a "optimal" type of notice on my site now that I see the numbers.

OK, I've done a little research. 32-bit does, indeed, represent the added 8 bits of an alpha (transparency) channel. We almost never see this in use, but it is getting more prevalent. One good example is in Windows XP all the icons are 32bit. I've enjoyed some menu transparency effects in my Windows2000 setup without realizing that's a benefit of 32bit color.
The extra 8 bits don't seem to play a roll in photographs (since there'd never be any transparency there). They are also unneccessary for most web browsing (since transparent GIFs use a 1-bit scheme built into the file) unless the site is using 32bit PNG files, which are very, very rare.Learn by teaching
