Need help with downsampling on HP Compaq LA2405x

Referring to: http://forums.guru3d.com/showthread.php?t=366244 and http://forums.guru3d.com/showpost.php?p=...tcount=167 I can use your software to SuperSample. I wrote the wrong word haha, Supersample is what I meant, as in I put a higher resolution than my monitor is, then that SHOULD be f. ex. 2560x1440 on a 1920x1200 which means I get a higher definition of the picture, as if you would be watching a 1440p video on YouTube on a 1080p monitor, you just get a compacted version of 1440 which makes edges less visible and so on (helping alot with AA) and this is called SSAA (SuperSample Anti-Aliasing) which downsamples an image (or frame in my case (at least should)) to remove jagged edges and by doing this it should refine the graphics of games and increase the definition of images (Referring to http://en.wikipedia.org/wiki/Supersampling) I would be very glad if I could get some help with this, as I am new to the whole Anti-Aliasing scene, and for my friend his Nvidia card optimised the resolution itself to be 1440p on his 1080p monitor, and according to him the results are amazing,"it is as if you would go from graphics setting Normal to Ultra" were his words about it.

Best regards , and waiting for an answer MadPixie.
