Whats the point of 32bit colour!
Switch from 16 to 32 bit colour on a CRT monitor and you'll notice a big
difference. But I've found no LCD monitor with a colour depth greater than 24 bit (8 bits per channel) Since LCD monitors are are now even sold with cheap systems, I guess the real question should be - WHATS THE POINT OF A GRAPHICS CARD WITH 32 BIT COLOUR! Until LCD monitors improve to beyond the point where computers can only be used as glorified DVD players or games consoles, I don't see why graphics cards manufacturers bother to offer higher and higher specifications. As a serious graphics user I would love to have a bigger screen, but the cost - in lost performance - is just too great. NB - I do have a small LCD monitor as well... Naturally, switching from 16 bit to 32 bit on that makes no difference at all. |

Both 24bit and 32bit produce the identical number of colors (16,777,216) on a monitor of any kind. In 32bit color mode, the remaining 8bits are used to render what's called an Alpha channel, which handles separate layers of transparency or translucency of images and objects. You'll see differences in 3D animations, digital video and 3D games. Not on a 2D desktop. Since these transparency effects do show up on the LCD's used by Apple running OSX and will do so under the upcoming Vista, running a 32 bit desktop vs a 24bit one will have visual differences under these circumstances. |

Forgot to add, many LCD's can't display 32bit with analog input. With DVI they do flawlessly. Try doing transparency effects with Photoshop or other graphical software with your desktop set at 24bit and see what happens. Try it again at 32bit. You'll notice that it now works. Even on your LCD monitor. |

Just emphasizing this point - it makes quite a large speed difference
in most cases (at the expense of memory space). In some cases, those extra 8 bits aren't used at all. It's just easier and faster to access memory in 32-bit chunks than separate 16- and 8-bit chunks. -- If there is a no_junk in my address, please REMOVE it before replying!

The optical difference depends on the creator of your desktop icons.
Turning windowsXP icons in 16bit makes them ugly,however there are very pretty icons that look great at 16bit. Nowadays videocards don't suffer much from running 32bit native,but older cards do get some performance impact due to the extra memory usage. And indeed,it's the lack of capability from certain videocards that they can't run 24bit,so they made them 32bit. Or it was too difficult or expensive those days so they skipped 24bit. There is some insight story on this subject which already exsisted back in the voodoo addon cards,or started at that time. So don't hang me on this for adding an incomplete statement.

Because there is no such thing as true "32 bit color" on PC systems. 32-bit color uses 24 bits for the color data, the remaining 8 bits are either used for something else like alpha (transparency) data or are simply wasted. The reason for using 32 bits rather than 24 is that video memory buses are multiples of 32 bits wide, therefore using 24-bit packed data could require multiple memory bus transactions to retrieve the data for a single pixel. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from Home Page: http://www.roberthancock.com/ |

Hey mister, you have any links showing the difference, since I am kinda
skeptical of this theory Bye, Skybuck. "Augustus" wrote in message news:d7Ilf.157078$yS6.49317@clgrps12... "Garry Rowland" wrote in message ...
