I'd suspect in that case Claude, that the lcd itself is doing some 
antialiasing actions. I have not actually tested that very much on my HP 
dv5120us with a wide screen other than to note that it was butt ugly when 
trying to run at 640x480, so it didn't take me long to change that, and I 
haven't otherwise experimented with it since.  Come to think about it, I 
think it is running at some slightly lower std when its booted to XP.  
The actually correct mode doesn't seem to be available in XP Home.

I suspect this would almost have to be a 'try it and see' thing on most 
lcd monitors. With the availability of single chip solutions for almost 
everything, its possible such a function might be incorporated in the 
better lcd units, but marketting wouldn't understand that as a desirable 
feature (generally speaking) so any mention of it would never make it to 
the outside of the box at Staples et all.
