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. >-- >Claude Jones >Brunswick, MD, USA -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
