Sorry for confusing

Btw I did made a mistake just now, it's 1920x1200 instead of 1920x1080, how come? 23" supposed to be 1080p isn't it?
Can a Asus ENGTX 460 support 1080p resolution? And will VGA/DVI result in the graphic being displayed?
Thank you

Even integrated G945 graphics can support up to 1080p, the rest will depends on what you want to do with that resolution.
If you game with that resolution, GTX460 should be quite enough provide you don't go for current high-end game and select very-high details in-game.
23" from general view is always 1920x1080 but your graphics card might not able to detect the native resolution properly thus might gives you choice of up to 1920x1200, you might see distorted image or cropped image.
You can post your monitor model here for much accurate analysis.
