Pixel mapping, Videocard and Samsung 226BW

I would be interested in going from a 17 inch CRT NEC Multisync 75 to a 22 inch LCD monitor. The Samsung 226BW seems a good candidate, but it seems that it can not do any 1:1 pixel mapping. As I want do continue playing old games on my computer (Heroes of Might and Magic, Starcraft, etc...) without stretching the picture, I was wondering if my videocard, NVIDIA, XFX 7600gt xxx, can handle "pixel mapping", scaling, or whatever the name is ? As my computer is not that powerful (AMD 3200+), that would also help me play new games at lower resolution that the native one of the LCD, when necessary. If the videocard can handle this, is this a good solution ? Is the image quality as good as normal ?

For the moment, the Samsung 226BW seems to me a good solution, but I think that Samsung is supposed to launch new models in August ? Any insight on those ? Any 22 LCD monitor with pixel mapping ?

Thank you for your help

Hi, i have the 931bw (the 19" model) and i have used the scaling method of my nvidia drivers (162.18) and it just puts the screen on 1280*1024 and makes it fit the screen :S (with the 16:10 ratio)

As far as i know it doesn't work
