Hi,
I recently got the hp zv5000z laptop with the 1680X1050 monitor and I noticed that black text is not perfecly black when you look close enough. Some pixels have all kind of colors. And I find it a little unpleasant. I also installed linux, and this problem was even more obvious. Luckily, somebody posted a fix for the problem which was identified as subpixel antialiasing. Here is the link:

So, the display works fine in linux now. But I couldn't find the solution in xp. My laptop has the nvidia Ge Force4 440 graphics card. Disabling antialiasing from the display menu didn't solve it.
Thank's.
