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.
