I want to reduce the saturation of my laptop monitor to the point that it is almost grayscale. That's the goal.

Intel and Asus don't have an answer. Asus Splendid and the intel graphics control panel can increase the saturation, but not lower it.

I would prefer a software solution, although I DIY'ed a vga grayscale adapter for my desktop.

I have an Asus UL30A with an Intel GMA 4500MHD. I know that the latest ATI cards, windotosh's and high end nvidia cards all support control panel desaturation.

Why? black and white makes me 3 times more productive.

I wonder how black and white can be more productive, it would annoy me a lot and you will lose the difference between colors... If you want, could you share an explanation? – Tom Wijsman Jul 2 '10 at 21:10
Have you tried High Contrast mode? – Hello71 Jul 3 '10 at 2:54
Basically, there is a correlation between fun and being unproductive, thus killing fun should make you more productive, appartely that is the case. – Oldarney Jul 3 '10 at 4:42
I use Macintosh computers, which can natively turn on/off the greyscale/color option, so it's easy to do what you want. To explain the "why" anyone would like to do that, I say that it generates much less radiation, so it's much easier on your eyes and, therefore, you can work for many hours without any visual effects from the display. If you wish to see any particular feature in color, you simply switch your screen to color mode in a second and that's it. Everything is simpler on Macs. Cheers – John Feb 18 at 15:41

I found a way using an accessibility software. It isn't perfect, but this program: http://users.telenet.be/littlegems/MySoft/DesktopZoom/Index.html can be set to zoom 1000/1000 and has greyscale modes of 4,8,16,32,64,128,256 colors. It works on xp and Vista. Only issue is that occasionally, the color peeks through before the program greyscales it. The invert mode is very much like the high contrast theme.

I am also interested in this solution, and I think that it could be done by using a color profile. Google for "Windows Color Management: Background and Resources" and you find "ICC profiles are used to communicate through the rest of the color management system to ensure that colors are represented accurately to users, regardless of the device used for display or printing. ICC profiles for devices offer great flexibility and control, and can be used to describe the unique color management capabilities of a particular device. To take advantage of ICC profiles in Windows, each device must have its ICC profile installed. This can occur automatically when the device is installed, or the user can use the Display Control Panel to associate a profile from the device manufacturer." This page: http://www.color.org/opensource.xalter allows you to find tools that can design those profiles that you can use in windows.

Good luck,

I tried this before, and I tried this again today. So far I havent' been able to do anything to my monitors color with that. My guess is that color management and color calibration are on the same fields, but are not the same thing. Good try though. – Oldarney Jul 5 '10 at 2:57
