1024x768 32bit color.

When 32 bits are used, there are 8 bits for red, 8 bits for green, 8 bits for blue, and 8 bits left over that may be used as an alpha channel for transparency.

How is transparency relevant to a monitor that refreshes 75 times a second?

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.

I'm running XP. You mean all that for just some icons? Seems like a waste if there's not much noticable difference. So someone running on 24 bits and Windows XP wouldn't see any icons?

They'll see the icons, but they'll be dithered.

I'm running 8 bit 256 colors, so if you see me post anything out here and the color stinks you'll know why.

...Nah, just kidding, I have no excuse. I'm set to 1024 x 768 resolution, running a 32 bit color setting and a 17" monitor.

Oh, but, did I mention I'm color blind? Yeah, that's it...I'm color blind.

21-inch flat-screen Mitsubishi
32-bit color (makes gradations smoother)
1280x1024

I don't know how you all survive on 1024x768---I go back and forth between the above setting and 1600x1200.

Depends. I often "cut out" a chunk of an image (like the center of that funny dollar bill engraving thing in another thread I did) and when you do that, the image data is 32-bit - the edge, which was not square, is defined by those extra 8 bits.

When moving just that section of the image, if the screen display mode is 32-bit, the software can send the clip directly to the disply card to move it, and it'll move with transparent edges. If the display is not 32-bit, but 24 (or less), then the image has to be clipped in software before it is drawn as it is dragged or moved. So a 32-bit display can add quite a bit of efficiency from the viewpoint of the application software. From the end-user's perspective, it buys you speed, which you may or may not notice, depending on how loaded your system is when you're moving clips like that.

And, yeah, on Windows 2000 or XP, it'll get you some cute icons and fade-in/out effects, too.
